SCIENCE, OBJECTIVITY & POSTMODERNISM
- Aparthib Zaman
The most unifying element between races, religion or nations is science. Here all speak the same language. It is common to see a Chinese scientist discussing research topics with say an Arab scientist in a conference, academic institution or research laboratory. There is a universal aspect of scientific laws, principles that crosses racial, geographical & cultural boundaries that is absent in other branches of knowledge(e.g history, arts, economy, law etc which are taught, developed and adapted to suit their respective nation or society). The programs in Physics, Chemistry etc. in an Arab, Chinese or US University cover the same topics and principles. The theologians of different religions have widely differing views but the scientists of all religions have identical "views" of scientific principles. A vindication of the point I am trying to make is nicely illustrated by the noted British American elite Physicist & Philosopher from Princeton, Freeman Dyson who, in his insightful book "Infinity in All Directions" credits a Bangladeshi Muslim (Dyson's own word) Physicist Jamal Islam as having inspired and helped him in his quest for understanding of what the possible ultimate fate of the universe might be, and to a Japanese Biologist Kimura for having helped him in a mathematical way in his quest for the understanding of how Life on Earth might have evolved (genetic drift through random statistical fluctuation). Incidentally, Jamal Islam is also mentioned in Frank Tipler's mind boggling book "Physics of Immortality" on page 116. As Physicist and former president of the New York Academy of science Heinz Pagels said: "What distinguishes scientific theories from the pictures of reality provided by religion, culture or politics is the intention of their creators that they be useful theories independent of their user's religion, culture, politics, sex, race, personality, feelings, or opinions (p-172, "The Dreams of Reason"). Nobel Physicist Steven Weinberg remarked: "The experience of listening to a discussion of Quantum field theory or weak interactions in a seminar room in Tsukuba or Bombay gives me a powerful impression that the laws of physics have an existence of their own." (From "Dreams of a Final Theory, p-47-48). Physics is the right choice as the laws of physics are fundamental laws of nature that are universal and any explanation of any aspect of nature eventually reduces to explanation in terms of these basic laws. All other branches of science are derived from these basic laws of physics with some additional assumptions reflecting the complexity of the individual instances. Pleasee refer to A scientific view of Life, death, Immortality for quotes from scientists substantiating this conclusion. The principles of medicine etc are not fundamental laws either but reflect empirical rules that can and sometimes indeed seem to be violated, but are nevertheless universal i.e not culture or tradition dependent. A nice illustration of this universality is by listing the following Nobel Laureates in Physics (with diverse ethno-religious backgrounds) and their work:
Often a cavalier view and misconception exists among many laypeople about scientists, scientific truths and scientific methodology itself. There was a common perception before (and still is among some) that the laws of science are discovered by bespectacled, absent minded scientists, working quietly away in their labs, dabbling with microscopes and playing with simple equations or graphs of the kind that one is familiar with in their high school math, adding here, subtracting there, tweaking numbers until they are hit by a piece of good luck. In fact the math that is used in contemporary science is quite sophisticated. The simple math of the early Greek and medieval times has evolved into an incredibly complex edifice of advanced math today that are applied to scientific research. This complexity is not just in quantity, in the sense that an entire page of equations of high school algebra or calculus being needed to express a physical law, but rather in the complexity and novel concepts, notations and structures needed to express a physical law precisely. The new notions themselves often require mathematicians to delve metaphysically into the realm of higher dimensions, far removed from ordinary experience, sometimes to a 11 dimensional world, for example in developing the superstring theory of spacetime-matter at the fundamental level. Also the stereotypical image of scientists diligently engaged in trial and error with experiments and equations until finally they hit upon something revolutionary is a myth as well. It is not realized by many that all the profound breakthroughs in scientific ideas are not due to just the patient and diligent tinkering of instruments and numbers, but due to the painstaking, disciplined mental work through mathematical analysis and observations following the scientific method. Although the inspirations behind the discovery of certain scientific truth may be epiphanic, but the formulation, verification and communication of such scientific truth requires the use of scientific methodology before it can attain the status of a universally accepted scientific law. Scientific method is the "conscience" of the scientists, so to speak, that guides the scientists and prevent them from succumbing to individual whims and wishes. It enforces a uniform rule of engagement for any scientist irrespective of affiliations to search for the objective truth about reality based on observations, evidence and logic. Technological marvels, which are results of applying those scientific principles through ingenious ideas using both theoretical and experimental techniques, however at times do require diligence and tinkering. Some layfolks even think that the laws of science are just the result of some abstract imaginations or mental constructs of scientists reflecting their bias for what they perceive to be true, and the scientific laws are just a post hoc mental constructs to explain away observations, denying the objective reality of scientific laws. They seem to equate the claims of truth by religions with scientific truths. But unlike religious and personal beliefs, which are considered true just by thinking it ot be true, scientific beliefs are arrived at and inspired by a desire to seek the truth through a systematic, repeatable, testable experimental and theoretical endeavors. Such endeavors have to be necessarily objective in nature for it to be verifiable by scientists collectively regardless of their affiliations. A scientific truth does not result from haphazard attempts. It emerges from a systematic series of tests and observations inspired by intuitive thinking, reasoning and evidences, aided by theoretical or mathematical analysis. The level and complexity of the mathematical analysis is often beyond that seen even in graduate level math courses. One need only glance through the pages of the book "The large Scale Structure of Space Time" by Hawking & Ellis or "The Mathematical Theory of Black Holes" by Subrahmanyam Chandrasekhar to appreciate this fact. Oftentimes lay persons are illusioned and take the profound scientific statements of reputed scientists for granted as obvious,simple, or armchair speculation, not realizing that pages and pages of sophisticated math that went into arriving at such a scientific conclusion in a precise way (An example being Hawking's mathematical derivation of a Universe with no beginning or end and the notion of "imaginary" time) and developing a theory based on such math that can predict any result that is a logical consequence of the theory, testable by the scientific community in a repeatable way. A full consensus of the scientific community crossing national, racial borders is an absolute prerequisite as well. The most important aspect of scientific methodology is its ability to predict and a scheme of verification/falsification of this prediction. All known scientific laws were established through verification of the predictions it made. A lay person is hardly aware of the ruthless and exacting rigor with which the prestigious scientific journals and their international referees screen a prospective article publicizing a scientific principle. Such is the firmness of an established scientific law or truth. A scientific law is not introduced in a cavalier way like the pseudoscientific theories of "Scientology", "Quantum Healing" and similar other new age myths that are not accountable and subject to any rigorous peer review and testing. One simply has to remind oneselves that there is good reason for these never being taught in the regular programs in any general Academic Institution, private or public. It is important to remember that only one violation of a scientific law is enough to topple it whereas a series of evidence/verification together with a mathematical and logical consistency tested repeatedly by peers help to establish one.
Many laypeople hold the view that something that cannot be "seen" by their eyes cannot be said to exist in a certain way but only conjectured. To them an electron or atom is thus not a real object, but a scientific conjecture. They miss the point that our individual senses are no longer the only reliable means of verifying, testing or predicting a truth or proving the existence of some entity. Our observable universe consists of visible and invisible domains, the macrocosm and the microcosm. The entities of the microcosm can be "seen" by more sensitive means than our limited senses. Scientific methodology has, over hundreds of years been able to perfect an objective systems of observations through the design of extremely (Cannot overemphasize this word) sensitive equipments & procedures that can measure one billionth of the thickness of a hair to give an example. Scientists today can "see" an atom by a Scanning Tunnelling Microscope. Add to that the extremely complex, sophisticated mathematical structure & language to express a scientific truth that defy human words. Scientists spend a substantial amount of time mastering this complex language before even beginning to express and converse about the truths with their peers. Our entire assortment of technological boons like T.V., microwave or for that matter any electrical/electronic appliance is based on the same principle that asserts the existence of electron, even the computer that the Software Professional was writing programs for. Saying that the existence of an electron is a perceived truth by the scientists is like saying that the existence of the computer he is operating is the result of his believing that it exists! Many educated people even doubt about the objectivity of Einstein's Relativity particularly its implication of time dilation etc. They don't realize the "Nuclear" bomb, whose existence no one dare doubt, is built and devised from the very same law that yields time dilation as its natural consequence. It is also sad to see the cavalier way some lay people and non-specialists dismiss many scientific theories/speculations just because it contradicts their subjective perception, belief or "common sense". Examples are "Big Bang", "Black Holes", "Time Warp", Superstring Theory, Antimatter, prediction of machines having consciousness beyond 2050 etc(As believed by Nobel laureate Scientists Crick and Edelman, Computer Scientist Marvin Minsky, Philosopher Daniel Dennett). The noted philosopher of this century Martin Gardner commented in 1983 in his book "The Whys of a Philosophical Scrivener" : I cannot say it is impossible for humanity someday to build a computer or a robot of sufficient complexity that a threshold will be crossed and the computer or robot will aquire self-consciousness and free will (p-114). Notice he is not saying that this WILL happen, only that it cannot be dismissed as impossible. Scientific theories are based on painstaking mathematical derivations based on well established fundamental laws of science or are propounded in a mathematical expression derived on the basis of some premise that seem plausible from observations. Once enough observational evidence in support of the consequences of the theory is accumulated the theory becomes a fundamental law itself. Scientific speculations are predictions based on existing natural laws but project its future extensions far beyond its current range of validity. For a lay person to dismiss or disbelieve such a theory or speculation, he/she has to point out the flaw (if any) in the mathematical derivation of the theory (For that he/she obviously has to master enough technical proficiency in the sophistication of the mathematical framework) or put forward an observational evidence to contradict the theory (Also has to be able to master the observational skill needed in the experimental field of that theory). A lay person is intellectually dishonest/wrong to dismiss the result of the painstaking work of the scientists. Here by lay person I mean those not trained in science, they can have PhD in non-scientific discipline. A lay person can with good conscience only confess that they don't understand or are not capable of comprehending or analyzing it because of their lack of necessary background. They can either accept the words of the science experts, read up enough to get a reasonable grasp, or just stay neutral. See http://www.csicop.org/sb/9803/reality-check.html for a related interesting article by Victor Stenger. Some post modernist social theorists also audaciously characterize Science as another cultural construct of human and question science's claim to objectivity. Interestingly these postmodernists use the same scientific results to propagate their outrageous propositions while declaring science as relative and not objective! This is a gross mischaracterization of science and scientific truths, which although tentative, but are nevertheless objective. As Werner Heisenberg said "In science a decision can always be reached as to what is right and what is wrong. It is not a question of belief, or Weltanschaung, or hypothesis; but a certain statement could be simply right and another statement wrong. Neither origin nor race decides this question: It is decided by nature, or if you prefer, by God, in any case not by man" (Quoted in p-267, "Dreams of Reason, by heinz Pagels). The truth about these postmodernists is that they are suffering from "science envy" and since scientific knowledge undoubtedly commands glory and respect, they cleverly try to wrest more respect by pretending they know more than scientists by proving that science is wrong. After all, if science requires high intellect then surely discounting science must require even higher intellect, so why not pretend to "debunk" science if you cannot understand it? Thats the ploy of these postmodernists. Another reason for these posmodernists to pretend to debunk science is because that would provide a convenient excuse not to go through the hard route of learning the difficult principles of exact sciences and apply them correctly to the social sciences. These postmodernists are nothing but armchair social scientists incapable to face the challenge of the hard sciences, who unlike some of their fellow social scientists (who have successfully tackled the scientific challenge) are threatened by the incursion of scientific paradigms and principles in their field. For them the appropriate maxim is "If you can't join them beat them" rather than "If you can't beat them join them" ! There are even some outrageous views like "scientific truths are the results of the mental constructs of the white males of Western society !". Thereare those who propose "Islamic Science", "Vedic Science" etc. Then there are feminist sociologists who take this post modernist view and advocate feminist science! (For debunking of such ludicrous view, see an article by a female philosopher Susan Haak where she takes on the preposterous position of Sandra Harding on feminist science at www.csicop.org/si/9711/preposterism.html. For another rebuttal of post modernist views,see http://www.godless.org/eth/round.html. Philosopher of science Noretta Koertge criticizes feminists' position of science at http://www.mugu.com/cgi-bin/Upstream/Issues/fem/KOERTGE.html . A Female freelance journalist Elizabeth Larson mocks feminist science in the April/May 1997 issue of Heterodoxy maganzine. The famous Sokal's Hoax lucidly illustrates this ridiculous attitude of some non/pseudo-scientific social theorists who pass irresponsible armchair commentaries on the value of scientific principles. For more on post modernist's abuse of scientific ideas check out Alan Sokal's Book: Fashionable Nonsense
Here are some excerpts from Fashionable Nonsense: :
"Science is not a text. The natural sciences are not a mere reservoir of metaphors ready to be used in the human sciences. Non-scientists may be tempted to isolate from a scientific theory some general "themes" that can be summarized in few words such as "uncertainty", "discontinuity", "chaos", or "nonlinearity" and then analyzed in a purely verbal manner. But scientific theories are not like novels;in a scientific context these words have specific meanings,which differ in subtle but crucial ways from their everyday meanings, and which can only be understood within a complex web of theory and experiment. If one uses them only as metaphors, one is easily led to nonsensical conclusions."Check also the following excellent and timely written books:
The Nobel laureate scientist P.B. Medawar said that "there are some fields that are genuinely difficult, where if you want to communicate you have to work really hard to make the language simple, and there are other fields that are fundamentally very easy, where if you want to impress other people you have to make the language more difficult than it needs to be." ("Third culture - By John Brockman, p-23). As Alan Sokal says in his book "Fashionable Nonsense": "Not all that is obscure is necessarily profound" (p-186). The renowned Biologist & author thinker Richard Dawkins says:
"And there are some fields in which--to use Medawar's lovely phrase-- people suffer from 'physics envy'. They want their subject to be treated as profoundly difficult, even when it isn't. Physics genuinely is difficult, so there's a great industry for taking the difficult ideas of physics and making them simpler for people to understand; but, conversely, there's another industry for taking subjects that really have no substance at all and pretending they do-- dressing them up in a language that's incomprehensible for the very sake of incomprehensibility, in order to make them seem profound."
Interestingly neither Medawar or Dawkins are physicists, but are biologists. Dawkins also said, apparently saddened by those pseudo/non-scientifc intellectuals who argue that science alone cannot answer ultimate questions about existence that:
"They think science is too arrogant and that there are certain questions that science has no business to ask, that traditionally have been of interest to religious people. As though *they* had any answers. It's one thing to say it's very difficult to know how the universe began, what initiated the big bang, what consciousness is. But if science has difficulty explaining something, there sure as hell is no one else who is going to explain it". (From End Of Science - John Horgan p-119)
Dawkins is right on the mark here. My point here is that when laymen, mystics or new age thinkers etc assert that "scientists or science cannot answer all questions or that one cannot/should not try to understand life, consciousness/soul/Creation of the universe etc using science", they are in fact themselves arrogantly claiming that their way (mystical meditation, pseudoscientific mumbo jumbo etc) is the "right" way to know them! So much for consistency! At least scientists are always basing on objective evidence and reasoning as their guide and constantly making room for revision and revocation and humbly confessing not knowing all the truth at any time. It is one thing when scientists say science is yet unable to explain some mystery and another when a layman or mystic says that. The laymen's assertion is an uninformed biased view. The scientists' assertion is an informed verdict. The two assertions are not by any means of the same weight or consequence. One may accidentally hit on the truth by random guessing, but it is not the same as arriving at the truth by systematic reasoning. The truth is not always what appears to be most likely from common sense. Our senses can be easily fooled as amply borne out by history.
Another unfounded view held by many non-scientific leftist intellectual is that it is impossible if not difficult to change the existing scientific paradigm by fresh new minds brilliant ideas specially if theses new minds happened not to be from the elitist white western male scientist etc, i.e basically they contend that the objective content of a new scientific theory is not judged in isolation but that the affiliation of the proponent figures in its acceptability. A single landmark exception will suffice to debunk this preposterous belief. Until 1956 the overwhelming majority (In fact 100%) of Physicist believed that Parity conservation is never violated in nature. Any new theory without evidence that went against this ingrained belief would almost certainly be dismissed. The belief in parity conservation was too strong an accepted paradigm to be challenged. Then in 1956 two Chinese physicist Yang and Lee first pointed out the exception and theoretically predicted non-conservation of parity. Initially there was predictable skepticism and it took further convincing work and subsequent experimental verification by another Chinese woman Wu and her colleagues and in 1957 the physicist community abandoned a long held belief in conservation of parity. Yang and Lee were not only vindicated,they received the Nobel Prize in Physics for this intellectual feat. So much for conservative western scientist clinging on to their scientific "beliefs" and refusing to accept any new ideas specially if proposed by scientists from different affiliations. This debunks two myths in one stone:
Another example debunking the first myth is that of Nobel
physicist Paul Dirac's suggestion in 1928 of the existence of anti-matter
purely on mathematical symmetry considerations. As bizarre and
far out this idea may have sounded back then in 1928 physicists
didn't ridicule it even though they didn't accept it either for lack of
observational evidence. When observational evidence did come in 1932
his idea was accepted and rewarded with the Nobel prize. Truth,
however tall sounding, ultimately manages to shine out. A very
opportune note can be found at by a female Professor emiriti of
Physics Nina Byers (See her page at
http://www.physics.ucla.edu/faculty/emeriti/byers.html) and Claude Pellegrin,
professor of Physics at the University of california at Los Angeles, at:
http://www.soz.uni-hannover.de/isoz/SOKAL/NYTREV6.htm. It is equally
disingenuous for laymen to observe "Of course, that's obvious, I knew it
all along" etc when commenting on some superficially trivial sounding but
truly profound statements by top scientists like Roger Penrose's assertion
that "Human mind/brain cannot be simulated by a computer (Turing machine)".
This assertion has a deep scientific connotation and is made to
refute the opposite viewpoint taken by top scientists in Artificial
Intelligence theory. This disagreement between Penrose and AI people
(Dan Dennett, Marvin Minsky etc) for example) is of a highly technical
nature and Penrose was not making a cavalier remark to echo what
mystics and pseudoscientists often make while discounting the role of
science in metaphysics and what laypersons perceive by their gut
feeling and common sense. This trivial sounding statement is a result
of a laborious research (Summarized in the two books, "The Emperor's
new mind" and "The shadows of the mind" in hundreds and hundreds of
pages). For a layman to quip "Oh that's obvious" is an arrogant, flip
remark implying he/she already is in possession of the insight that
is reflected in Penrose's conclusion based on his painstaking
cerebration and whose conclusion is nevertheless debated by top
scientists from Harvard, Carnegie-Mellon etc. Similarly when top
scientists express the views that in about 50 years it may be
possible to create intelligent machines possessing consciousness it
should not be cavalierly discounted by laymen but should be debated
with authoritative expertise in artificial intelligence, brain research
and mind/matter research based on Quantum theory. Laymen and
quacks etc seem to thrive on dissenting views of scientists. They
quote the views of the side which seem to be favourable to theirs and
claim that their view is supported by scientists! The fact is that
the two dissenting views of scientists on an issue differ on a fine
level and the two sides nevertheless agree on 80% or more of a
detailed and technical knowledge of the issue on which their
dissension is based. The quacks and laymen are totally ignorant about
those detailed technical background. So for a layman or quack to claim
that their view is supported by scientists is nothing but and disingenuous.
In other cases the laymen or quacks point to the
dissenting scientists and conclude that since the scientists differ
with each other so they are all wrong and its them (laymen/quacks)
who are correct ! (conveniently ignoring the the broad area of
agreement between the two dissenting scientists). As a final example,
when cosmologists state that vacuum has no weight, laymen should not
jump to a derisive laugh and say "Phew. Isn't that obvious? How can
empty space have weight anyway?" etc. Emptiness(vacuum) is more
than meets the laymen's eye. A deep study of quantum theory and
general relativity reveals empty space to contain virtual particles in
various modes of excitation and the fact that ordinary vacuum has
zero weight is a fortuitous result of the Grand Unified theory of matter.
Another example is the question why is the night sky is dark. To
a layman this may sound like a silly question, but it is not,
according to Physics it should not have been dark IF universe was
infinite with stars or space was not expanding, So there IS a
deep cosmological reason behind night sky being dark.
The bottom line is that so called "common sense", "gut feeling",
"intuition" etc are not always guaranteed to be a reliable guide to an
objective truth. They all reflect to some extent our desires and
wishful thoughts deeply ingrained inside, though in many cases they
are indeed right, but NOT ALWAYS, and it is this exceptional cases
that a true scientists ruthlessly tries to guard against any veil of
illusion and deceptive appearances that might creep in through fond
wishes and habits, by deductive, objective cerebral work. And it is
through these deductive cerebral intuition that some of the the most
bizarre yet valid predictions and theory have sprang forth that defy
usual common sense and intuition of laypeople, like time dilation,
quantum non-locality, matter from vacuum, many worlds etc. A
layman's intuition is almost invariably based on his/her wishful desires
and is believed in naively by him/her but is constrained by his/her
refusal to think in a more detailed and careful way. A scientist's
intuition is almost always based on an assumption of symmetry and
simplicity of nature, but is refined by deeper and careful thinking
and is always considered tentative. So it must be emphasized that
just as in order to establish a theory one has to get it screened and
reviewed through highly respected journals by a wide body of scholars
crossing national boundaries and actively involved in the field and
most importantly borne out by clear objective (indicated by unanimity
of scholars of diverse background) evidences, it is equally true that
to declare an established theory wrong one has to go through the same
rigorous path. Unfortunately often one is seen to cavalierly dismissing
a theory just because it seems too abstruse to him/her. Humans have
learened enough sobering lessons not to jump so quickly in accepting or
dismissing any notion without careful investigation.
SCIENCE VS. MYSTICISM & PHILOSOPHY - Aparthib Zaman
It is commonly thought that understanding of mind, life,
consciousness etc belonged to that vague discipline called
"Mysticism" or religion and that science cannot, or should not try to
deal with them. Layfolks often defend Mystics & Theologians by saying
"You cannot judge their approach to truth as wrong using logic or
science". Laymen, mystics and theologians also feel that questions
of life, consciousness etc should be handed over to mystical philosophers,
spiritualists and, theologians, not scientists. Nothing could be
further from the truth. By their aversion to materialistic
pursuits and adhering to ascetic life style, the "mystics" may seem
to create an aura of wisdom and superior cognitive power. This is not to
question the sincerity of ALL the mystics, many do have the genuine
yearning to grasp the meaning of the ultimate, but to question the
means they are adopting and more importantly their claim (or putative
claim by their defendors) to having the most priviledged, if not the
sole access to the ultimate reality and their disdain for scientific
methodology. Some may not disdain scientific methods but still belittle
science by calling it just "another way" among many in the the effort
to learn about reality. By implication they view scientific way as no
better than any other way, mystical, religious etc. It is a serious
mistake to equate the objective methods of science with just any other
subjective belief systems. If someone claims to experience a very personal
feeling of higher state of consciousness (in whatever subjective sense),
or a sense of heightened illumination about some transcendent reality,
that is perfectly acceptable as long as he/she characterizes it as such
(i.e subjective). But when these experiences are attempted to
formalize and made into an "ism" such as "mysticism" or when such
personal subjective experiences are defended by others as equally "real",
"objective", "true" like science, that is going a bit too far.
"Divine" experience, if such existed, cannot be obtained through a
prescribed set of regimens which when followed
will yield that privileged experience to any individual. If that
was the case it would become a routine mechanical method for
anyone to attain ultimate insight and thus would be amenable to a
scientific analysis and would be integrated with mainstream science.
Such a prescribed regimen for any Moe/Joe to follow by "joining" the exclusive
mystical school in order to experience the same personal subjective
senses of illumination, ceases to be of any spiritual or
transcendental nature. A divine experience or truth (about a transcendent
world or entoty), IF it exists at all, cannot be acquired through pure procedural
regimen. Truth about nature (non-transcendental,phemomena), on the other hand,
may possibly be obtained in an epiphanic
flash like it came to Einstein (Any such about nature, i.e a platonic truth,
can be viewed as divine/religious in a sense, since that truth is not the
creation of human mind, but a discovery), who out of pure metaphysical intuition
grasped the truth that the space time we live in is curved (This concept has a
precise objective meaning that can be shared with others, which no mystical
"truths" possess). His insight is an enlightenment about objective reality and
is not tangible through ordinary intuition but is amenable to the
objective language of mathematics and physics, and to empirical
observations of a very high sophistication. That's how his
metaphysical insight was elevated to a universal truth. A divine
"feeling" of enlightenment on the other hand cannot be translated
into an expression capable of objective communication and so has to
be solipsistic. Any belief in such amounts to a belief in testimony.
Moreover a pure procedural regimen to stimulate such feeling
will necessarily imply a non divine nature of the same, because
the outcome of a mechanical procedure is necessarily a phenomenon,
not a noumenon. Any attempt by mystics to elevate a personal subjective
"feeling" of spiritual enlightenment and call it a universal truth and
prescribing some regimen for others to experience the same would be disingenuous.
It is true that through meditation and other induced means brain can
go into an altered state which can produce a feeling or sense of
enligtenment, joy, fulfilment, unity etc. That in itself does not
imply that a contact with a transcendent entity/truth has been established,
although any individual may justifiably believe it to be so in
their own mind. At the end of the day it is really to each his own. Anyone can
"subjectively" claim to have grasped the ultimate mystery of life.
It is quite possible that mystics, meditators etc may experience
some subjective feeling of enlightenment/vision/hallucinations etc,
(Aviators when subjected to severe and sudden change of motions
causing substantial oxygen deprivation to the brain also report
similar psychedelic experiences, sort of induced effect of mystical
mediation. In fact Harvard researchers have concluded that the
experience of mystical meditation is indistinguishable from altered
brain states induced by certain drugs. So for the mystics,
theologists & laymen to go one step further and assert that they
have gained access to the ultimate truth and reality is a stretch.
No real substantive or cerebral work goes into their pursuit to
back up their presumptuous (though repetitive and often self
evident truisms) talks and preachings. If at all any truth is
arrived at through mystical means (meditation etc), then it cannot
be communicated to others because it is bound to be highly
subjective and subjective thoughts and realizations cannot be
communicated unambiguously to others and generate the SAME
subjective perceptions in them unless an objective language
(symbolic/mathematical) is developed. No mystical studies have
ever developed such objective language. Subjective perceptions or
sensations may be stimulated in others through communication of
rituals/regimens prescribed by some "mystic", but understanding or knowledge
cannot. There is a crucial difference. Understanding inevitably involves
knowing truth (Not personal perception of such). And truth requires
an objective means for its expression and verification. And objective
expression requires an objective language (Math & Logic, Natural Laws,
as expressed in terms of well defined concepts etc) to be unambiguously
communicated. Mystics, New Age thinkers emphasize cognition
through intuition. But the cognition that their non-inferential intuition
results in cannot lead to the truth, at best a perception. Scientific
intuition is inferential, and is necessarily a prelude to en eventual
expression of an objective truth, once the intuition is developed
, refined and verified. Intuition, does play a crucial role in
science. But unlike mystical intuition, scientific intuition does not
end by a vague verbal assertion. A truth in the real sense
must lend itself to a universal objective expression or an
inferential derivation for it to be communicable and an objective
criterion for its verification/ falsification. For, without a
consensus reached through such communication the mystic's "truth"
becomes a solipsistic concept devoid of any substantive value. No
mystical studies have ever developed such objective expression
of truth and its verification, and so cannot honestly claim to
communicate the "TRUTH". On the other hand the hard sciences
(Specially physics) do have the sophisticated objective language
to not only communicate but to understand in a fundamental way
subjective perceptions on such issues as mind, consciousness, life
and reality in general. This is what has been and being done by
scientists like Roger Penrose, Henry Stapp, David Deutsch,
Paul Davies and others. None of these great yet humble physicists
claim that Physics in its present form has solved the problem of
explaining consciousness/mind/reality but that it may be explained
fully in future by extending the present structure of physical laws
through further discoveries and break throughs, if not within its
present purview. The boundary between science and metaphysics &
philosophy is getting thinner each day. It is inconceivable that
one could grasp the mystery of mind or consciousness without ever
knowing the facts of Quantum coherence or collapse. To appreciate
this one need
only to check this link out on the attempt of a theoretical Physicst from
Berkeley to understand consciousness. Here's another link
of another PhD Physicist Evan Harris Walker's attempt to understand
consciousness, and another on the inevitable role of Quantum Physics
on consciousness research.
It is fair to say the ultimate truth about reality, if ever is
explained, will be done so not by just by pursuing a formal study
of reductionist Physical principles or non-cerebral meditation of
mystics, but through a combination of a strong grasp of the
reductionist principles of Physics and preceded or accompanied by
metaphysical reflection/intuition. So either a Physicist has to become
a "mystic", or a " mystic" has to grasp the fundamental truths of nature
through a thorough grounding of the reductionist principles of Physics
and mathematics in order to seek the truth about reality. That's why
most of the leading minds in the area of consciousness and mind
research are either from Philosophy, neuroscience or mathematics
who have spent enough time to train themselves in the advanced
principles of Physics and mathematics (Dennet, Lockwood, Chalmers
et alia) or are Physicists who are equipped with the knowledge of
the workings of brain/neurons (Penrose,Stapp et alia) and spent
enough time in metaphysical intuition and thinking. In their book
"Where God resides in the brain", authors Allbright & Ashbrook says
in p-xxv that theoretical physicists are exceptions in the usual
dichotomy of mystics and scientists. They appreciate the particular but
also seeks order and theoretical beauty in ways reminiscent of
mysticism. And on page 32 they comment that neuroscience resides
between physics and metaphysics.
Dan Dennet is a distinguished
philosopher (Educated in Harvard and Oxford) who is well versed
in science and bases his philosophical ideas on solid scientific
insights in an authoritative way unlike pseudoscientists and
mystics. Richard Dawkins, the celebrated Biologist who insists on
precision, has even objected to labelling Dennet as a philosopher
rather than a scientist!. After all, bare mysticism/metaphysics strives
to deal with intangible entities and constructs to arrive at some
higher level of reality/truth based on the fundamental intangible
entities. But lacking the necessary tool, it is bound to fail. On
the other hand that's exactly how physics works. After all,
uncertainty principle, quarks, superstrings, curvature of spacetime
etc are the most intangible concepts which through series of
intricate deductive mechanism give rise to higher level of reality
of forces, matter and most all phenomena in the visible world and
life. Traditional mysticism is a poor man's (intellectually,
figuratively speaking) attempt to connect to the platonic reality.
Metaphysical reflection based on the principles of Physics and
Biology etc, on the other hand are the sophisticate's way. I must
emphasize that no derogatory connotation is implied here. Its just
that a well-intentioned effort is misdirected in the former case.
It requires both the necessary tool and the proper mind frame to
get the best possible grasp on reality. Some of the mystics may be
well intentioned and have the desire and mental capacity but lack
the necessary tool (A deep knowledge of Physical laws and
mathematical logic) and hence do not really achieve anything
substantive, in terms of contributing to out understanding on the
fundamental reality for others to share. Metaphysics without Physics
is like a car without fuel. It can go nowhere. The noted Cambridge
Philosopher Michael Redhead
says "Physics and Metaphysics blend into a seamless whole, each
enriching the other, and that in very truth neither can progress
without the other" (From "Physics to Metaphysics", page-87). Just as
those who undergo rigorous and arduous physical training and
exercise are the most capable of performing tasks that require
physical skill by the same token the principles of advanced Physics
and mathematics enforce a rigorous mental exercise and training
that makes one prepared for an effective metaphysical speculation.
What could be intellectually more rigorous a training than say the
mathematics of the 11 dimensional hyperspace of Superstrings?
Metaphysicians/mystics with no reductionist training cannot in an
unambiguous and objective way, formulate/express reality of life and
universe but do so in a vague and highly subjective
manner that is only amenable to blind veneration and subjective acceptance,
prompted by biased and wishful desires and. Also merely quoting or
paraphrasing the truths of Physics (Quantum non-locality etc) by
so called Quantum healers/mystics to back up their vague mystical
affirmations does not/should not impart legitimacy to such
assertions. One has to pay their dues through a formal training
in the natural laws of Physics. It is simply an intellectual
dishonesty to assume that all the fundamental facts and truths of
nature discovered by painstaking mental efforts of brilliant minds
are all useless or irrelevant and one can bypass them and gain
direct access to some ultimate truth about reality by some vague
mediation efforts alone. As physicist/skeptic Victor Stenger
says his book "Physics and Psychics": "Despite widespread
belief to the contrary, mo mystical revelation has ever told us
anything about the universe that could not have been inside
the mytic's head all along. The most basic truths about the
universe - its size, constituents, the fundamental laws these
constituents obey, and humankind's place in it -- are nowhere
even hinted at in the sacred scriptures that recorded the
supposed revelations of history's leading religious and mystical
figures" (p-10-11, Physics and Psychics). Even if it was true that
some special soul by some freak did gain access to ultimate reality
through some meditation (Or may be without it, why even mediation, if
it is a divine gift?) then he/she would be a lone inhabitant of an
island of enlightenment since no other ordinary human being can ever
grasp what the special person knows or feels, there is simply no
mechanism to communicate it, other than a blind belief on his/her
words generated in the minds of the ordinary folks through their
charismatic traits (Ascetic life style, detachment from
materialistic pursuits etc).
It may be noted as a side that it is far easier for a physicist to
get up to speed with neuroscience than it is for a neuroscientist
to get up to speed with quantum theory, due to the inherent
difficulty of grasping Quantum principles let alone its
mathematical complexity. It should also be noted that it is Physics
which is APPLIED TO neuroscience and not the other way around in
the attempt to understand mind/consciousness. It is no surprise
that most of the leading brain/consciousness researcher are from
Physicist background, like John Hopfield, a quantum physicist
turned brain scientist (Pioneer in neural net) appled Q.M. to
neurons. Miguel Virasorz is a superstring theorist turned brain
scientist (neural net. bottom up approach). Particle Physicist Leon
Cooper (Nobel Laureate Physics) also turned into brain scientist.
Physicist Eric Harth (Author of the book "The Creative Loop" and
"Windows of the mind") also worked on mind/brain research for
many years which has added valuable insight.

Even Russell envisaged the role of physics in brain/consciusness very early
in his essay "Cosmic Purpose" from his book "Religion and Science" where
he said that Physics and Psychology will eventually be merged into one
science. Mind and matter will not be the issue, but events". He also says
in that essay that the belief that personality is mysterious and irreducible
has no scientific warrant, and is accepted chiefly beacause it is flattering
to our human self-esteem. (from "Critiques of God").
In more recent time distinguished scientist and editor of prestigious Science
magazine John Maddox in his book "What remains to be discovered" says on p-278:
"Psychology will be a branch/handmaiden of Neuroscience".
Let me now move on to the meaning and relevance of Philosophy
in the classical sense, in the context of today's world. The word
Philosophy literally means love of knowledge. In ancient times the body
of knowledge was too small and there was no division of labour among
knowledge seekers. Philosophers were people who tried to understand
everything in life including the structure of matter, origin of the
universe, life/afterworld, consciousness etc. Not being aware of the
natural laws that we know now they came up with unique and often
ridiculous theories to explain everything. As you can see Zeno's
paradox baffled scholars at that time, whereas today an average
college student can figure out the flaw. Calculus was not known in
Zeno's time. Here's an interesting quote by Dawkins from his BBC
lecture in November 1996 : "You could give Aristotle a tutorial. And
you could thrill him to the core of his being. Aristotle was an
encyclopedic polymath, an all time intellect. Yet not only can you
know more than him about the world. You also can have a deeper
understanding of how everything works. Such is the privilege of
living after Newton, Darwin, Einstein, Planck, Watson, Crick and
their colleagues." (For the remainder of Dawkin's lecture see:
http://www.world-of-dawkins.com/dimbleby.htm
Another Scientist and renowned author E.O. Wilson writes in his book
Consilience(From http://www.theatlantic.com/issues/98apr/biomoral.htm):
..
"Had Kant, Moore, and Rawls known modern biology and experimental
psychology, they might well not have reasoned as they did. Yet as this
century closes, transcendentalism remains firm in the hearts not just of
religious believers but also of countless scholars in the social sciences
and the humanities who, like Moore and Rawls, have chosen to insulate
their thinking from the natural sciences"
For another example lets take Hume's reasoning in Inquiry V II:
This is ridiculous and simplistic by today's standard. We can
certainly "prove" that it will, based on geometry and theory of
gravitation. Its not just a belief based on past observations. Of
course it will be a truism to say that there is no guarantee
that the proof itself is not a guarantee that the sun will rise
tomorrow. But then that is simply playing with words, one is not
saying anything deep. After all what would mean by "guaranteeing"
in this context? The proof is certainly there, however it is
defined. In light of modern knowledge in Physics, Evolutionary
and molecular biology, psychology, neuroscience, all the
speculations, questions, reasoning etc of classical philosophers
seem puerile today and reflects an ignorance of the deep
knowledge of the Laws of Physics, Biology (evolutionary/
Molecular/Neuro). Nevertheless they stand in high esteem for
the manner in which they reasoned and thought despite the
primitive knowledge database that existed in their time. No
one really needs to study them now to gain insight in life and
nature. For that they need to study Physics/Cosmology,
Evolutionary and molecular biology in depth AND (that's the
vital part) try to understand the meaning of it all (i.e think
metaphysically). Mere reading in a fact gathering manner, like
feeding data into a computer is not adequate for human insight.
Humans today have been passed down a gene pool that contain the
cumulative knowledge over millions of years and a research Physicist
or a Molecular biologist today knows more about nature and life than
the combined knowledge of all these primitive philosophers of ancient
days. Even religion (eschatology) now is a more properly addressed
by Cosmologists. The incredible level to which Physics and the
Biological sciences have progressed has radically changed the
traditional meaning of Philosophy in modern context. Philosophy
today is primarily study of logic and epistemology. Logic is more an
integral part of mathematics, and the rest of philosophy is only
meaningful as a historical study of the evolution of human thought,
epistemology and reasoning. Basically, Kant, Hume, Heidegger,
Wittgenstein etc have put to rest all philosophical/metaphysical
speculations by showing that they are just constructs of words with
no meaning beyond that can be conclusively arrived at by consensus
thru any objective means. All previous philosophical ideas are
nothing but subjective verbiage of individual abstract ideas which
can never be tested/verified or agreed upon in an universal way
except for the obvious statements of individual perceptions that are
common to all in an intuitive way (The feeling of mystery and awe
about the infinite universe and its creation and existence etc). Here'
s an interesting excerpt from cognitive scientist Roger Schank (See
his bio at http://www.engines4ed.org/hyperbook/misc/rcs.html) who held
triple faculty positions in Computer Science, Education and
Psychology, referring to the remarks on consciousness in Mortimer
Adler's "Syntopicon" by old philosophers like Aquinas, Montaigne,
Aristotle etc : "These people have vague hand-waiving notion of what
consciousness is about, with a religious tinge to it. Their work
wouldn't fly at all in modern academics. Yet we're being told that if
you haven't read them you aren't educated. Well, I'm reading them,
but I'm not learning much from them. What I'm learning is that people
have struggled with these ideas for the last two thousand years and
haven't been all that clever about it a lot of the time. Now, with
the computer metaphor, and a different way of looking at the idea of
consciousness, we have entirely different and new and interesting
things to say.." Stephen Hawking, in the final chapter of his
celebrated book "A Brief History of Time" quotes the eminent
Philosopher of this century Wittgenstein as saying that the only
meaningful work left for philosophers today is the analysis of
language ! Nobel Laureate Gerald Edelman has commented: "Philosophy
is the graveyard of isms". Another nobel laureate Francis Crick
(Codiscoverer of DNA) has said "Philosophers had such a poor record
over the last two thousand years that they would do better to show a
little modesty rather than the lofty superiority they usually display"
. All the so called deep philosophical verbosity on Life, Soul, etc
be it in Buddhism, Hinduism, Sufism, Hellenic Philosophy etc, can
never be boiled down to any tangible fact or a precisely formulated
truths of life/nature i.e there is no real substance but some rich
literary/poetic/romantic imageries. To be a true seeker of knowledge
(i.e philosopher) one has to understand the deep laws of Quantum
Theory, Cosmology, Chaos theory, Molecular Biology. Reading on the
early Philosophers and their works are only for historical interest
and to understand how human thoughts have evolved and advanced with
time to the sophistication today. The theories of Aristotle, Ptolemy,
Copernicus appear so obvious and elementary today. But they were the
pioneers of their days. But the combined knowledge/insight of top
Physicist, Molecular Biologists and all the other disciplines today
will far surpass the combined insight of all the ancient
"philosophers" in existence. Today's hard sciences are ready to tackle
even issues that were considered the exclusive realm of religion/
ethics/spirituality etc. In fact the laws of physics ARE the Laws of
nature and the laws of biology are the laws of Physics (in the
emergent form), so ultimately, Life/Consciousness, End of the World,
etc will all be in the domain of Physics ("The Fabric Of Reality" by
Oxford Physicist David Deutsch states this premise in a remarkably
elegant and convincing way). In fact all contemporary philosophers
(who still survive as a species) of today are either former
professional Physicists/Mathematicians/Life Scientists or have strong
background in such and constantly invoke the deep truths of those
disciplines to construct their philosophical ideas. Science provides
the "raw material", so to speak, for the philosophical speculations
and views. Scientists themselves are so occupied in the actual hunt
for the truth and refining it through painstaking series of precise
tests and observations that they can hardly afford to pause and
speculate about the metaphysical implications. But many do, and
they are to me truly the true philosophers, like Paul Davies, Roger
Penrose, Richard Dawkins etc. For example Philosophers have debated
and written profusely on morality, ethics etc, but they all in the
end analysis, reduce to verbal meanderings with no remarkably
significant insight. But if these issues of human life is viewed in
the light of the profound truths of evolutionary biology, genetics
etc they do provide some remarkable insights into it, an example
would be the ideas of Richard Dawkins as outlined in his book. "The
Selfish Gene". Even the concern of the philosophers on the issue of
the limit of human knowledge is more effectively dealt with through
mathematical principles and Quantum Theory. So my whole point is
that there is no such viable thing as philosophy in isolation from Science.
Philosophy is just the pursuit of understanding of life and nature
through "thinking" and this understanding is only possible, if at all
through Science. Up until the thirties, there were intellectuals
devoid of scientific background who were monopolizing the profession
of "thinkers" while scientists merely writing technical books on
scientific principles, forming two distinct cultures. Now it is the
time of the Third culture where Scientists themselves are taking the
role of thinkers since nobody with little or no scientific background
can even dare think on the profound issues of life which are so
intimately a part of scientific pursuit today. Modern philosophers of
Science are really doing their thinking on ideas and issues
that are already the result of the work of scientists by first
mastering the ideas and then working on the implications and/or
extrapolations thereof. For example look at the 1988 article at :
http://www.infidels.org/library/modern/quentin_smith/uncaused.html, to
see what a 36 year old PhD in philosophy had to say about the origin of
the Universe (Warning: Maybe too mathematical for you). All the
contents of this article refer to the work of cosmologists(Scientists) like
Einstein, Roger Penrose, Stephen Hawking, James Hartle etc. For other
examples of philosopher's subject of study see the other articles by
Quentin Smith at www.infidels.org/library/modern/quentin_smith/.
Finally the book "The Ends of Philosophy" by Harry Redner does a post
mortem of traditional philosophy and the attempts to revive it new
form. Click here for excerpts from the book.
Einstein in an obvious sense of pity for the moribund state of philosophy
commented in 1932 "Philosophy is like a mother who gave birth to and endowed
all the other sciences. Therefore one should not scorn her in her nakedness
and poverty, but should hope, rather, that part of her Don Quixote
ideal will live on in her children so that they do not sink into
philistinism. (From p-150, "The Quotable Einstein")
SCIENCE, LOGIC, FAITH & BEAUTY ETC - Aparthib Zaman
A mistaken perception among many is that people who
tend to be logical, rational or scientific (henceforth abbreviated
and referred to as LRS, in alphabetical order, not in order of
importance, and will also be used to refer to logic, rationalism
and science) in their thinking, lack in the finer sense of
aesthetics, appreciation for art, humour, or are incapable of feeling
human emotions like love, passion, fantasy, faith etc. This view
is erroneous and a myth. Not only can they show all these human
emotional sensitivity but even have a belief in something not
provable by science (This may not have ever occurred to many, will
be clarified later). Thinking logical and rational is a way
of organizing our thoughts and actions to avoid unnecessary
fallacies and misunderstandings that result from careless or
cavalier thinking or reasoning. It is of practical significance,
intellectual aside, and is mutually exclusive of, yet compatible
with purely "natural" human emotions like love, (com)passion,
imaginations, daydreaming, fear etc. Appreciating logic and insisting
on it in speech and actions that are of impersonal nature does not
prevent one from appreciating a piece of artwork, or to hug someone
or hold someone's hand and look into their eyes with admiration. So
one should not immediately jump to such an impression about anyone
by his/her logical remarks or insistence on logic. Often remarks like
"Logic or reason cannot apply to emotions, love, beauty etc", "science
ruins the beauty and mystery by trying to explain it" etc are commonly
heard, the classic example being of the English poet Keats who accused
Newton of ruining the beauty of rainbow by explaining it with the laws
of optics. Other poets have also made sarcastic references to science
in their poems, like Eugene Cummings, Emily Dickinson ("A color stands
abroad, on solitary fields, that science cannot overtake but human nature
feels.."), Wordsworth and others.
It is not just a coincidence that this kind of remarks are
never made by those who understand science truly, i.e the scientists
or science literates. This allegation that trying to explain or
underatsnd beauty ruins it could be tested by asking those who make
this statement to read themselves how rainbows are formed and
see if the beauty of the rainbow is dimisnished to them. The common
response is "I don't want to underdtand it", reflecting a closed
mindedness in this regard. Besides these remarks sound like answering
a question that was never asked, or refuting a conclusion that was
never made. No one ever says or suggests that Logic or science
"applies TO" emotions, beauty etc. Science or logic does not have
any relevance to the experience of the "feeling" of love or beauty.
But that does not by any means imply that logic and reasoning cannot
be of any help to understand the origin of such experience
of love, appreciation of beauty etc. Such understanding is within the
domain of modern science specially the new field of "Sociobiology" or
more specifically "Evolutionary Psychology" where usual human traits
like selfishness, aggression, altruism, love etc are explained based
on the fundamental lessons of Biological Evolution in terms of
the workings of gene and hormones. There have been a
good number of books published by scholars and research workers
explaining the evolutionary biological basis of human emotions
and perceptions, like "Why We Feel: The Science of Human Emotion"
by Victor S. Johnston, "The Feeling of What Happens: Body and
Emotion in the Making of Consciousness" by Antonio R. Damasio,
"Emblems of Mind: the inner life of music and mathematics" by
Edward Rothstein (see http://www.maa.org/reviews/emblems.html),
and "Math and Music : Harmonious Connections" by Trudi Hammel Garland
et al, are just to name a few. Trying to understand the origin
of emotions in terms of a more basic underlying natural principle
through scientific reasoning does not mean that science or logic
negates or belittle those emotions themselves. Then why so many
harp on this defensive statement when no such contrary statements
are made by scientists? The reason may be rooted in the inherent fear
of the truth. For many the truth may destroy the idealistic mental
images that their romantic imaginations create and inspire them in a
personal way. There is a propensity among most humans to live with
wishful thinking providing a sense of purpose, security and inspiration
to move on in life. But a mature insight into the truth should not
interfere with these personal images but should complement it
instead. First let me tackle the issue of LRS vs. beauty, passion,
mystery etc. Those who choose intuitive OVER rational approach in
thoughts and actions and are critical of LRS (henceforth to be referred
to as NLRS), are heard to pass comments like "LRSs kill the beauty by
trying to explain or understand beauty". I must clarify that
dividing people into LRS and NLSR does not mean there is an
inherent difference between them. All humans have similar potentials
and attributes in varying degrees that are manifested and expressed in
varying degree by a combination of gene and environment. Anyway,
the NLRS are making a subjective judgment in the comment above.
I should also point out that intuitive approach is not discounted by LRS
totally. To LRS intuive approach is also importajnt, but complementary
to LRS, but LRS is primary. No what does kills the beauty mean? Does
it mean it kills the capacity of the LRSs or NLRSs to appreciate art or
beauty? How can an NLRS judge the pure subjective qualia of artistic
sense in the minds of an LRS, who may not at all agree with that
statement? And how can the attempt to explain by LRSs have an effect
on the mind of NLRSs so that they will cease to appreciate beauty, love
due to that attempt by LRS? There does not seem to be any connection.
Many NLRS may also think that LRSs feel less of the qualia of love
and other human emotions due to their effort to understand those
feelings rationally. For all we know many scientists have a quite a bit
of sense of beauty, and they feel that their appreciation of beauty is
enhanced by knowing the object or phenomenon of beauty at a deeper
level. Just as trying to understand the working of the brain does not rob
the neurologists of their own brain or stops it from functioning, the
act of trying to understand the deeper meaning of love and beauty
does not rob the LRS of their inherent sense of beauty and ability
to appreciate it. An astronomer is not less appreciative of the wonders
of night sky than a poet, but may instead be more appreciative, because
an astronomer may already possess an inherent poetic frame of mind
and also an additional passion to understand the mystery behind the
formation of stars and galaxies in terms of the principles of Physics.
What possibly can make it impossible for an LRS not to be moved by the
beauty or charm of a flower, a charming woman (for a male LRS)
or a charming man (for a female LRS)? I tend to believe that I am an LRS.
But why is it that I am attracted to surrealism in visual and aural art,
why am I touched by hauntingly beautiful music, poetry etc? These are not
explainable nor demanded by LRS thinking. Of course which music or poetry
appears to reflect beauty to an individual is purely subjective. But we
all are equipped with the potential to feel and experience beauty.
An LRS has the same genetic structure and capability to appreciate and
enjoy beauty as an NLRS, despite the fact an LRS follows the valid
argument forms of Modus Ponens, Modus Tollens, Hypothetical Syllogism
or Disjunctive Syllogism!.
Inherent sense of beauty or sense of awe and appreciation are mostly
genetic traits in humans in various degrees and are not affected
by any other genetic traits like propensities to understand or explain
things at a deeper level. They are mutually exclusive. In other words
if sense of beauty, compassion, love etc are determined by one genetic
factor (say gene-1) and the propensity to understand and search for
deeper answer through LRS way is determined by a second genetic factor
(say gene-2) then gene-1 and gene-2 are mutually independent, not affecting
each other. My reasoning using gene-1,2 etc is for heuristic purpose.
Things may be more complicated than that. In the book "ORIGINS: Cosmos,
Earth and Mankind" by Hubert Reeves et al, leading biologist Yves Coppens
has traced the origin of the emotion "love" to the gradual increase in
the gestation period of women of the early hominids
(Australopithecus Afransis), houndreds of thousands years ago.
Einstein saw beauty in the laws of nature. Beauty is symmetry. And
it is by believing in the beauty of nature that Einstein, Dirac and
numerous other physicists came to the most insightful realizations of
the secrets of nature. Behind their profound discoveries lie the
motivation from a sheer metaphysical sense of beauty and mystery of the
universe. But Einstein was also moved by music. he used to play violin.
Nobel laureate Feynman was an accomplished Bongo player. The Nobel laureate
Physicist Chandrasekhar who wrote a 650 page mathematical tome "The
Mathematical Theory of Black Holes" also wrote a book called "Truth and
Beauty" in which he emphasized the role of sense of beauty behind the
motivation of scientific thinking. To him, art, seen from this
scientist's point of view, seems to be all the richer for it, contrary
to popular belief that rationality strips Art of its elemental passion.
He drew the parallel between the works of Shakespeare, Beethoven,
Shelley etc with the beauty inspired approach of scientists for the
search of the truth. A very fascinating marriage of beauty and
mathematics can be seen in the works of mathematician/artist Escher
(http://www.geocities.com/SoHo/Museum/3828/air.html). The renowned
British astronomer and prolific author John Barrow also has shown how
beauty and truths of natural laws are closely related (not antagonistic)
in Part 6 Titled "Aesthetics" in chapters 23 & 24 of his fascinating
book: "Between Inner Space and Outer Space" (see
http://hallsciences.com/astronomy/871.shtml). He discusses the evoutionary
origin of sense of beauty among early hominids. Those primitive senses
of beauty had adaptive value like all other evolutionary traits. But
today that primitive sense has reached an elegant level beyond any
adaptive value.
LRSs feel that the mystery even deepens and becomes more interesting
as they understand more. Actually the truth is that a mystery is honoured
and elevated by the pursuit of its explanation and understanding, not
diminished or ruined. Providing a simplistic answer like it is the work
of GOD, or only GOD knows, or that only the mystics, theologians or
psychics can grasp the ultimate reality it doesn't really recognize
the mystery but kills it by closing all the doors of a better
understanding through a disciplined mental efforts via scientific
metaphysics. All scientists at the bottom of their heart
appreciate more so deeply about the unknown than anyone else. After all,
one can only appreciate the unknown best by knowing all that can be known
first. The mystery of the universe is best appreciated in the secret
code of nature that has been cracked by science so far and is constantly
being cracked as an ongoing process. Also LRSs admit that there exists
an ultimate mystery that is unexplainable. For example one can start asking
why to each phenomenon (As Nobel laureate Weinberg does in his famous
"Dreams of a Final Theory"), say starting with a phenomenon "D".
LRS:
NLRS:
Now lets stare at the two. Who was showing more humility? One who
acknowledges ignorance at some deeper level when no answer is possible,
or the one who at any level, has some predetermined answer of some divine
or spiritual "force" being behind all, whether it is A,B,C, D, and makes
a judgemental statement that it ruins the mystery or beauty in trying
to understand it?. Who really is ruining the mystery and who is keeping
it alive? Points to ponder.
For example, for LRSs "A" now = the Standard model of particle Physics,
or potentially in future, the M-Theory version of Superstrings. In other
words:
Standard Model(or M-Theory)->All of Physics->All of Chemistry->All of Biology->Life->Economics..
Of course the details in some arrows are lost in the laws of emergent
phenomenon like complexity, chaos that are almost impossible to know but
are in principle traceable to the Standard model or can be added as a
supplementary rules along with it. But no LRS can claims to know what
the origin or explanation for the existence of the standard model or
M-theory is. That is the end point of human ken.
Next take the case of love, (com)passion etc. NLRS often pass
comments like "Love, kindness, human emotions" are not rationalizable.
Its beyond logic or science. What are they really trying to say?
Scientists do try to find a layer of reality underneath each human
traits including that of sense of beauty, love (As the example of
Yves Coppens mentioned earlier), etc which are
supervenient on those lower phenomenon and appear as epiphenomena. But
does that really imply rationalizing the subjective feeling (qualia) of
love itself that we all human (LRS or NLRS) feel? Does it even make any
sense to say that? Then why such comments are made? I will get to it
later. NLRSs often pass the remarks that logic is cold, lacks compassion.
To assign an emotion or lack of emotion to logic is a fallacy. One can be
logical and still be compassionate. Judges are known to be stickler for
logic. But they are also known to be compassionate. A judge convicts a
person based on logic and evidence, but can use compassion to grant
pardon in some situations. No conflict their between logic and compassion.
But logic had to be used to distinguish a pardon from an aquittal. A
logical person does not cease to be logical by donating to food bank or
to poverty/hunger alleviation projects, and logic does not prevent one
from doing that. On the other hand some of the cruel punishments on
women and writers have been meted out by those who do not rely on
logic and rationality, but on faith and intuition.
It is also a mistaken conclusion that a scientific and skeptical
mind cannot have any belief. Let us be careful with terms now. Faith
is an unquestioning belief in anything, even if that belief contradicts
logic or scientific evidence. But not all beliefs are faith. Some
beliefs are based on evidence and/or logic, like belief in the theory of
relativity, or belief that earth is round. Some beliefs are not based on
evidence or logic but also do not contradict them either, like a
belief in extraterrestrial life. Then there are beliefs in objects or
notions that are ill-defined, reflecting ignorance at some deeper
level, which may or may not contradict logic or evidence depending on
how those notions or defintions are formulated. A belief in a such a
GOD in some of its versions (not a personal God of revealed religion,
but as an abstract concept or belief in immortality in some abstract
sense) is not inconsistent with a skeptical and rational thinking, because
a vague notion of a GOD and an equally vague notion of immoratlity makes
it impossible to subject such beliefs to logical or scientific or logical
analysis. Belief in an abstract God and life after death are the kind of
inborn instincts in human that are not amenable to logic and logic is not
contradicted if one FEELS this instinct. The term "God" reflects two
aspects of human nature:
A good example of a skeptic rational philosopher who believes in
such a GOD and immortality but otherwise doesn't believe in any
existing religion or faith is the eminent Philosopher of 20th
century, Martin Gardner. (See his book "The Whys of a Philosophical
Scrivener"). Martin Gardner is a rigid skeptic and logician/
mathematician who has been a regular critic of pseudoscience and new
age mystics debunking myths through the columns of The Skeptical
Inquirer magazine of the "Committee for the Scientific Investigation of
Claims of the Paranormal" (CSICOP) but also believes in Immortality
and his own concept of GOD. Why? He plainly admits that in his
book, because he wants to believe in immortality and GOD,
and since logic/science is not violated by this belief (But God
of the traditional religious IS contradicted by logic and evidence)
he can happily believe in it! It is important to keep in mind that
Gardner does not CLAIM that God exists or that immortality is true,
and is not an avowed theist. His personal instinctual belief in God
and immortality is probably better described as a wishful thinking.
A second example is that a scientifically inclined person may
believe in the "Omega Point" concept of GOD (cf. "Physics of Immortality"
by Frank Tipler). Since the existence of Omega Point cannot be observationally
tested (At least at the current time) believing in it cannot be a truly
scientific act but nevertheless a physicist would not be violating scientific
principles by believing in it either, since it is consistent with Physics and
certainly plausible in Physics terms and provides the best concept of GOD as a
"belief". Physicist Frank Tipler not only believes in Omega Point,
but also goes a step further to prove that such a GOD is an end result
of the evolution of life and universe and will become an omniscient,
omnipotent entity that purely arises out of a consequence of the
natural laws. Although some premises have to be true (which
are not known at this time if they are) for Omega Point to become a
reality, Tipler chooses to "believe" that the premises are true because
it doesn't violate any known scientific laws to believe in those
premises. This is a clear example of believing in "God", resurrection,
immortality etc, although is a very special sense, while still adhering
to the strict principles of Physics and LRS, because Omega Point Theory
is falsifiable in principle. If the ideas of Tipler sound Intriguing,
check more at http://niazi.com/resurrec.htm or
http://www.doesgodexist.org/JanFeb96/PhysicsOfImmorality.html
Tipler is a Global general relativist, a formidably mathematical field
and his work comparable to that of Hawking. He can be taken as a
prototype of an LRS.
In fact while it is true that most scientists
don't subscribe to the traditional beliefs in personal GOD and the
revelations of a book as the word of the GOD, many are in fact
deists, where the deity for many are just the "Laws of Physics".
From a traditional theistic point of view that is not much different
from atheism. Einstein believed in a Cosmic Consciousness which he
identified as Nature (Called Spinozza's God). These scientists
refer to their vague beliefs mostly to avoid being looked upon
as atheists or due to the two reasons mentioned earlier. I already
mentioned Omega Point. Its just that they don't believe in the usual
personal concept of God as a father figure somewhere up in the heavens
monitoring the day to day activities of each mortal, talks to them
through the revelations of a book written in a certain language,
who demands daily worship by the mortals and gets angry if they don't
, and prepare a ledger for final rewards and punishment for not
following the revelations. Since scientists admit that the very
source or origin of natural principles are not explainable by the
natural laws themselves, there will remain an ultimate mystery of
the unknown. Scientists usually don't label that unknown with any
term, although some do use the word GOD metaphorically like Hawking,
and Einstein as mentioned above.
The belief in Many Worlds/Parallel universe is another example of a
belief of scientists that cannot be tested scientifically but is nevertheless
quite consistent with Physics (Quantum Physics to be exact). Many physicists
strongly believe in many worlds (And many other ideas of Quantum Metaphysics)
and some (Like Penrose) in fact "believe" that Quantum Metaphysics and
Global General Relativity are the link between tangible world and the intangible
world of consciousness. It may be that paranormal phenomena, IF they exist at all,
may eventually be "explained" (i.e shown to follow from natural laws).
Many scientists believe in the so called Anthropic Principle.( See the link
at http://www.winternet.com/~gmcdavid/html_dir/anthropic.html)
which is as close a scientist can get to "GOD" (Intelligent Design) as possible,
staying within the purview of scientific rationality. Notice that no explicit
mention of God is there in its discussion. "God" has to be read in it by pure
metaphysical extrapolation which is certainly valid to anyone rational. Indeed
the Anthropic Principle which is stated as a one liner in popular books like
Hawking's Brief History of Time) is really very complex and detailed. A 700
page book called "The Anthropic Cosmological Principle"
(see http://home.planet.nl/~gkorthof/kortho17.htm for a review)
has been devoted to it by Tipler and Barrow whose names have been mentioned
earlier. If the summary review in the preceding link looks
abstruse then one should wonder how much insight the 726 page original
book may provide. It is my personal biased view that by understanding this
726 page book one can get the most "spiritual" feeling. But in no way the
instinctive feeling of God from Anthropic principle need to be passionately
preached as an absolute truth about God, that would be the fallacy of the
design argument for theism. Anthropic principle itself cannot speak about
a designer, only about design. But intelligent design is also not established
beyond doubt, because Physics cannot rule out any other explanations for
anthropic coincidences. In fact explanations do exist, like parallel universe
theory, among others. The facts of Anthropic principle are objective
(expressed in Physics language). The conclusion derived therefrom
is just a subjective one.
A belief, therefore to be consistent with skepticism
and rationalism, must fulfil two requirements: (1) It cannot
contradict logic, evidence or scientifc principle. (2) It cannot be
claimed as a truth with the same status as scientifically established
truths and has to be held as a personal belief. It is important to
realize that a belief which does not contradict science does not
necessarily mean that it is explainable by science.
There may exist unexplained phenomena in nature. In absence of any yet
known natural explanation even a scientific mind can speculate/hypothesize
a plausible cause which is not scientific (In the sense that it cannot be
tested by observation), but metaphysical, which nevertheless doesn't violate
the existing natural laws either. But to a skeptical mind such a belief is
an ad hoc one which is subject to revision/generalization/extension if
more insight is gained.
So Rationality or logic does not REQUIRE "not believing". But one has to
distinguish between beliefs rooted in instincts and beliefs generated by
blind belief through human indoctrinations (scriptures, prophets etc),
and of course informed beliefs based on evidence.
Finally some speculations(Speculation is not inconsistent with LRS!)
Why is there a sort of instinctual fear and aversion towards LRS by the
NLRS? Two different plausible reasons at different level comes to mind.
Is it that there is an instinctive fear of logic, rationality, science
due to their potential in leading us to unpleasant truths that one wishes
not to face or admit? A truth which may shake up long cherished values
that we all harbor deep inside? If so then it seems natural to express
that fear by dehumanizing or demonizing the LRS and rob them of these lofty
human qualities by portraying them as devoid of all softer qualities like
love,compassion, filial piety etc. After all, these are valued by ALL of
humanity, so by cleverly manipulating popular perceptions against LRS by
stripping them of these valued traits, the NLRSs can successfully marginalize
the LRSs. thus minimizing the risk of facing the unpleasant truths that only
LRS can expose! I am not saying this is consciously done, but may simply be
instinctual. The second reason at a more fundamental level may
be due a evolutionary legacy. Humans in past had to rely on intuition
and reflexes a lot to survive and make quick decisions, to avoid
predators for example. So intuition and impulses may have had adaptive
value in past, logic and rationality were not. We are reminded of
the famous fable of Buridan's ass, where an ass starved to death
becasue he stood in the middle of two identical haystacks but could
not decide which one to eat first! Humans still have an atavistic
tendency to discredit traits that were not evolutionarily adaptive
in past, even though it may be vital today.
SCIENCE, MIRACLES & THE PARANORMAL - Aparthib Zaman
Often when someone asserts their non-belief in any religion and belief
in rational thinking it is assumed by many that they also cannot (or
should not) believe in paranormal phenomena. This is a
mistaken conclusion. Belief in any given religion stems from
a totally blind faith in all the divine revelations professed in that
religion. But the belief in the existence of paranormal can result
from even a rational mind who realizes the limitations of human knowledge
and the possibility of hitherto unknown physical/natural laws being the
raison-de-etre for these phenomena and that has the potential of being
explained in principle IF those laws are ever discovered. This is totally
in line with scientific thinking (or rather scientific metaphysical thinking)
which allows for existence of laws not yet known. It is a mistaken idea
of many laypersons that scientists are haughty, overconfident people who
pretend to be able to explain everything and that they dismiss as impossible
anything that cannot be EXPLAINED by KNOWN scientific laws. Scientists
only declare that nothing has as yet been observed that VIOLATES any
well established KNOWN natural law. The crucial thing to realize is
that VIOLATES is not the same as UNEXPLAINABLE. If something cannot be
explained by any known natural law but at the same time does not violate
one then scientists are open minded about it and only try to give a
plausibility arguments using Occam's Razor as guide to explain it, provided
its existence itself is fiorst established beyond doubt, or else it will be
wasted effort to explain whjat does not even exist.
The important point to realize is that Science does not say
Paranormal events DO NOT or CANNOT EXIST, only says it has not
been proven conclusively to exist, so to assert its existence or try to
explain would not be a scientific pursuit
One need to realize that all the physical laws that are known now (e.g
Einstein's theory of relativity, Quantum theory of matter, Newton's Laws, etc)
were true and were at work in nature even before their discovery. In the same
vein their can be many undiscovered laws at work in nature at present which
may explain those phenomena. This is exemplified in the views of Roger
Penrose of Oxford that some new principle in Physics must be integrated
within existing Quantum Theory and Theory of Gravitation to explain
consciousness. Nobody can say if all of the undiscovered laws will even ever
be known. Nobody could have guaranteed the discovery of Einstein's theory, it
just happened coincidentally. The subtle undiscovered laws of nature, if any,
might potentially be a manifestation of the so called Theory of Everything (TOE)
that scientists believe exists and are striving to discover.
It may be that we may approach incrementally to that nirvana of knowing
the ultimate law and thus increase our understanding continually and incrementally
but never quite reach there. After all, science is more a process of getting
closer to the absolute truth, not necessarily discovering THE truth of
nature. But also one should NEVER ignore the fact that within a certain
domain of applications the truth may be known in 100% accuracy, for example
the fact that computers, TV, microwave, Rockets, Atom bombs etc work certainly
proves that the truth of natural laws is known with certainty within some domain
of applicability. The whole point
is by recognizing the possibility and keeping one's mind open on the
possibility of paranormal phenomena one is asserting this view, rather than
contradicting their rational thoughts or their non-belief in institutional
religion. For example reports of Poltergeist,apparition,spirit etc have
been quite common in human history, some even by persons of credible reputation.
There may indeed be such phenomenon, which may be manifestations of purely
natural laws (Not anything divine as the religious books hypothesize).
In fact there are quite a few plausibility (ad hoc) arguments to explain its existence.
An example of such is the after shock of an unnatural death which gets
recorded in the ambient articles (walls, furniture, etc) of the place of
the death and this recorded aftershock replaying itself like a phonograph
record playing back to reproduce the song that was recorded from a real
human voice. Brain chemistry with a Qunatum coherence in the nerons, or
sensitivity to earth's magnetic fields have been putatively invoked to
explain Psychic abilities. Underwater streams, High voltage electromagnetic
fields etc have been attributed to hauntings in houses and dowsing for example.
These are not scientific explanations, but still an attempt to
explain through plausibility arguments based on natural laws. Poltergeist
events have been attributed to brain's ability to influence matter, or
brain's ability to create a perception of movement of objects. On the other
hand there has also been recorded incidence of man made Poltergeist
activity called "Hutchison Effect" where poltergeist like movements of
articles were induced in a non-repeatable way by purely physical means
(But without any explanation). Click here
and here
for discussions of such effects. Click here
for a plausible explanation of Hutchison effect. And this
is the website for all about Hutchison effect. But interestingly none of the
phenomena that are reportedly perceived in a haunted house VIOLATES a known law,
only that the haunted events cannot be explained by any law. No one has
ever conclusively shown that an object floated still in space without support
(Can be a hallucination but to prove it actually happened needs objective
demonstration and witnesses), an example of violation of a physical law. Reports
of flying object SEEN in a deserted, haunted house sound spooky, unexplainable
by any law, but it DOES NOT violate any laws of physics, since SEEING is
a subjective perception not susceptible to scientific scrutiny.
The most scientific attempts in explaining Psi phenomena has been by
invoking the concepts of Quantum Physics. Nobel Laureate Brian Jospehson
(mentioned in Science & Metaphysics-2) has remarked that if Psi events had not
been reported, an imaginative theoretician could have predicted from
Quantum Theory that they should occur! (p-141, "Explaining the Unexplained:
Mysteries of the Paranormal" by Eysenck & Sargent). Physicist author
Amit Goswami goes even further and says more explicitly on page 136 of
his book 'The Self-Aware Universe': "Psychic phenomena, such as distant
viewing and out of body experiences, are examples of the nonlocal operation
of consciousness...., Quantum mechanics undergirds such a theory by providing
crucial support for the case of nonlocality of consciousness".
Physicist Olivier Costa de Beauregard of the Louis De Broglie Foundation(formerly
of University of Paris) has remarked that the most Fundamental axioms of Quantum
Mechanics demand that Psi events must occur as a result of the spatial
temporal (Lorentz)invariance elements of EPR paradox. Prof Beauragrd has worked
on an aspect of Quantum theory that asserts that the present decisions can
influence the past, a phemnomena callled "retrocausation" in Quantum jargon.
This was first suggested by Physicist Wheeler, it has also been developed more
recently by Physicist Stapp of Berkeley mentioned in Science & Metaphysiocs-2"
before. This retro-causation has been extrapolated (metaphysically of course)
to an extreme by some physicist to theorize that the creation nof the universe
itself may be a retro causation by the conscious act of observation by humans.
This is the position taken by Physicist Amit Goswami in his book "The self-Conscious
Universe". Anyway this spatio-temporal inavariance of Quantum Mechanics has also
led to a prediction of what is known as retro-PK in Psi phemomena, which is
testable. In retro-PK, a psychic can supposedly alter the past output of a
Random Event generator by proper mental concentration at present! Although
claims have been made to the actutal observation of retro-PK by researchers
like Schmidt, they remain controversial without sufficient scientific scrutiny.
Probably the physicist who went the furthest to apply Quantum Physics to Psi
phenomena has been Evan Harris Walker whose name was also mentioned in
Science & Metaphysics-2.
In a series of papers and his book he has proposed a model using the notion
of Collapse of Wavefunction and the notions of observer, observation process
and the observed. His work is summarized in the book cited above. Many
paranormalists invoke ideas of Quantum Mechanics to explain Psi phenoena,
although such theories are not truly scientific, because thay are not
falsifiable, and do not have preditive power. For example Physicist/Paranormalist
John Hasted of the dept of Physics at the Birkbeck College of the University
of London has speculated that Psi events can be explained by the "Many World"
theory of Quantum Mechanics by Evertt and Wheeler. Walker's work however do
have testable consequences. A very nice illustration of a purely scientific
(i.e natural) way of giving plausibility arguments to explain the alleged psychic
phenomenon of mind influencing matter (A random number generator in this case) is
to be found on line at: http://prola.aps.org/abstract/PRA/v50/i1/p18_1 This is a
highly technical paper. The psychic phenomenon is disguised in the technical
jargon "Causal Anomaly". The author (Stapp) is a theoretical physicist at Berkeley
and the paper was published in the Physical Review, a highly prestigious
journal and as a testimony to the genuine scientific nature of this work
By Stapp one just needs to take note of the fact that the work was supported
by U.S. Department of Energy ! (P.S. Unfortunately access to the details of the
paper now requires subscription. I read the article when it was open to
all. The fact that mind can influence matter is also reported informally
by many. Nobel Laureate Physicist Wolfgang Pauli was notorious for his
alleged influence on laboratory equipments, which reportedly used to stop
functioning in his mere presence.!
Parapsychology is a discipline that is contorvesrial in its place in adademia.
It is not totally dismissed as outside maintream science, nor intergrated
as equal peer with others. One skeptical psycgologist was asked when would
he take parapsychology seriously. He answered "When I see it in Hilgard and
Atkinson" referring to the respected textbook on Psychology used widely in
US and other countries. The 1990 edition of Hilgard & Atkinson did include
a 7 page section on parapsychology where the authors expressed the opninion that
while most of the skepticism towards PSI is well founded, some are not.
Parapsychology is increasingly becoming integrated with main stream psychology.
That is because many Physicist and Psychologists
have joined in this field to try to discover whether Psi phenonmea is real or
not. This is unlike Astrology where a very pseudoscientific rationale is
provided for the validity of astrological claims, and astrology has also
attached to it the stigma of fleecing the public exploiting their weakness
and sense of insecurity.
It may be that the data of the Gauquelins on the supposed correlation between
planets' position and the birtn of many genius, poets, and sports champions
is true. But correlation does not indicate any causation. Its like trying
to see what a lottery winner did on the day he picked the lucky number and try to
relate some of his activities on that day to his winning the lucky number.
Coincidences are possible both for individuals and for a collective group.
The rules of Probabilty does not rule out any concidences. Theorizing causation
based on correlation is a clear logical fallacy.
Many of the data that supposedly establishes the validity of Psi
phenomena have been produced and collected by scientists from academia.
For example Psychiatrist Dr. Ian Stevenson published two papers in the
prestigious Journal of Nervous and Mental disease based on his reincarnation
studies that point to many unexplained cases of "reincarnation".
But many results have been controversial. While many of the work by
Physicists and scientitts do indeed show a definite non-random evidence of
Psi, the very statistical nature of the evidence and the lack of any
scientific usefulness (no model to work with, no predictive value etc)
makes them less appealing to mainstream science. Add to that the impossibility
of reproducing the exact obseravtion by others. While the existence of
"dark matter" can be easily verified by astronomers/physicists anytime with
the proper tool and training, these parapsychological data are results of decades
of individual painstaking effort, which would be diificult for anyone to duplicate.
On the other hand, the REG work by Physicist Helmut Schmitd of Boeing, Robert Jahn
of Princeton Engineering Anomaly Research(PEAR) group has shown somewhat
convincing (but not truly scientific) experimental statistical evidence of Psi
ability of human mind. JB Rhine of Duke University in the late 30's also used
ESP cards to show the reality of Psi ability of mind. Another pioneer Charles Honorton,
also from academia, introduced the Ganzfeld experiemnts where barins psychic
ability were allegedly enhanced by sensory deprivation. But again, all
these being not in the line of true scientific method, such works are
not considered "proof" of Psi phenomena, nor any proof of any "divine", "spiritual"
nature of such, but nevertheless they help to counter a curt dismissal of
its non-existence by critics. For a detailed discussion on Psi phenonmena
from the parapsychologists' view point the book "The Conscious Universe" by
Parapsychologist Dean Radin is a good refernece. Radin does a meta-analysis
of many ESP experiments that allegedly shows that while individual psi
experiemnets may not be significant, as a whole they do point to a significant
bias towards its existence. Not surprisingly many scientists, like Victor Stenger
have discounted meta analysis as unreliable. It should be mentioned that even though,
science or scientists as a community may not have fully integrated parapsychology
in science, but MANY scientists exist who belive in the actual EXISTENCE of
paranormal phenomena (e.g the names mentioned above), in view of the statistical
results of the PK experiments. But these beliefs are in no way comparable to
the belief by some "scientists" in the traditional religious scriptures
and God. The latter is not consistent with rationality. Not each and every
"scientist" need be rational in their personal beliefs.
Other cases in point are faith healings. Although faith healing is
not conclusivley proven by controlled methods, there are anecdotal cases.
Even hypothetically assuming some faith healings work, there may be
plausible natural explanations. The cases of faith healings cannot
however qualify for miracle label. Because no known natural law is
violated. Besides the usual placebo effect explanation, we cannot rule
out other plausible natural explanations. The point I wish to make is
that one need not invoke divine explanation. Even a a vague speculative
explanations based on science is a better explanations than ones
based on appeal to the unknowen or blind faith. For example one can
try to explain it by a strange concept called counterfactuals in
Quantum Mechanics where it is known that the mere act of opening
up of the possibility of an event "A" can influence an event "B"
even if "A" did not actually happen. (cf. "The Shadow of the Mind"
by Roger PenRose). In a similar vein it is possible that the act of
merely placing firm belief in something (God) through intense
meditation (prayer/faith/can open up the possibility of certain
unknown event "A" (possibly some neuronal rewiring in the brain),
that can counterfactually influence another event "B" to happen
("healing" in this example), even though the target of the faith
(a personal God) may be non-existent or false. i.e the fact that
faith in prayer to a personal GOD actually helped in a given instance
of healing does not guarantee that the object of the faith (personal
GOD, divine revelations etc) are true, but that the *act* of placing
a faith in such an object had a favourable tangible effect through the
workings of natural laws. It might just be a purely quantum mechanical
effect. The above was not a scientific explanation, but was just made
to illustrate the fact that a plausible, ad hoc (not truly scientifc)
explanation can be based on science without using any divine notion or
term or any blind irrational belief, like a belief in a contradictictory
notion of a personal God heeding to such prayers. Many such ad hoc
explanations of paranormal phemomena are offered by parapsychologists.
Those explanations are not scientifc (falsifibale, testable), but need
not be wrong either. With some exceptions (Like Walker, Josephson, Beauregard
etc), most parapsychologist do not have sound technical background in
Quantum mechanics. And most professionsl Scientists do not have
the time and motivation to review the scientific accuracy of such
explanations, since parapsychology by definition, does not deal with
phenomena that are observables, which is exclusively what science
deals with.
A plausible ad hoc explanation not invoking irrational notions is that
of mass prayer. Again, no conclusive evidence exist for the effectiveness
of mass prayer. Assuming there is any authenticity to it, the alleged
result of mass praying may also be a purely natural process
(a cause-effect scenario) which itself may have its own effect depending
on the various boundary conditions that can accompany an instance of
praying (individual, mass etc). A prayer is basically an intense wish/
thought (an intense activity in the brain) and hence a natural process
that CAN interfere with the environment (and hence the individual who is
praying). Like Physicist philosopher Paul Davies writes in his book
"The Cosmic Blue print" even an act of thinking involves the motion of
electrons in the neurons of the brain and is bound to affect the rest
of the universe. In this view, a mass prayer is more intense and more
likely to impact the environment than an individual, if at all there is
an effect. By the way prayer here is meant in a generic sense of wishing
with intense meditation, not necessarily by reciting verses of Bible or
Koran etc. A desire to exert an influence on the laws of nature is meant.
It is an intense mental desire to manipulate the natural laws (which
do contain quantum uncertainties to allow for multiple potentialities
of reality) to yield a reality favourable to the prayers. Some current
views of paranormalists even posit that mass praying can have effect
on physical world in a similar vein as Quantum non-local effects are
manifested in physical act of observations, i.e an unexplained yet
purely natural cause/effect or interconnectedness/correlation/synchronicity
can in principle exist without any divine connections. Again these are
plausibility arguments, not scientific, but neverthless does not invoke
any transcedental or divine considerations. My point here is to emphasize
that paranormal or miracles, even if they are shown to exist does
not force one to resort to a divine explanation, there still can be natural
explanations, although not scientific in the strict sense. But the important
point to keep in mind is that any such explanations cannot be promoted to a
scientific status, or cannot be a basis for claiming the actual existence of
Psi phenomena, which are yet not conclusively proven to exist. The only
reasonable view would be to not permanently rule out the existence of
any paranormal events.
It is also possible that the pattern of correlation that is observed
between certain phenomena that is traditionally explained
as divine intervention can be just built in nature and part of the subtle
interplay of natural laws at work (analogous to Newton's law of action/reaction
or the law of conservation of energy etc) and not due to the intentional
act of intervention by an entity with consciousness. Sometimes they seem
to be random and not follow any persistent pattern. That may be due to
the inherent complexity of the natural laws which make it impossible to
predict, just as the laws of complexity preclude weather prediction, although
the weather still strictly follow the laws of Physics and can be often
predicted in a statistical sense.
It is the nature of our world that the path to truth is full of impediments.
the major impediments are gullibility/naivette, self complacency and
cynicism. Gullibility results from an inability to exercise one's critical faculty
and accept blindly other's views as authentic without ever bothering to
examine the credentials of those proposing the ideas and views. Cynicism
leads to an obsessively negative view of everything and hence failing to
recognize/acknowledge even the objective truth. Self complacency is due
to a false perception of knowing everything and not realizing the the technical
nature of some topics that only can be fully understood, proposed or challenged
through appropriate expertise only. Sometimes the overzealous laypeople paraphrase
the views of scientists in catchy words and propagate misleading interpretations
and thus create a domino effect of public myths. Then the scientific community
helplessly takes a back seat and decide to go about their own important
business and not even bother to stop the domino effect. The entire myth
of Teletransportation, UFO, Philadelphia experiment etc bears testimony
to this unfortunate reality. Take another example. When quantum mechanics
was formulated by the great physicists in the third and fourth decade of
this century, they became aware of some strange and profound aspects of
the theory(Like non-locality etc). These Physicists when debating among
themselves used to refer to the word "mystical" in expressing the wonder
at these profound implications, and the pseudoscientists quickly exploited
this word to promote their own alternative theories and cults quoting and
paraphrasing these words by physicists without really understanding themselves
what those really meant and unconscientously touting their ideas/views
to be supported by the Quantum Theory of Physics. Nowadays one can hear
New Age mystical Quacks using the "quantum" word to plug their own vague
ideas of healing and making millions from gullible public. New Age Mystics,
healers etc have unabashedly exploited Quantum theory without understanding
it. Check the link http://www.csicop.org/sb/9806/reality-check.html for an example
of one such attempt to justify "spiritual healing" through modern physics.
The fact is, these esoteric aspects of Quantum Theory/Cosmology is too
complex to be taught technically at even the usual graduate level Physics
curriculum and is only studied in specialized graduate level courses and
by Research Physicists at the post graduate level. Nature's mysteries and
secrets are unfortunately hidden in complex symbolic codes (mathematical
structures) that can only be understood and decoded by the complex symbology
of mathematics, and once they are decoded by Scientists they then phrase
them in simpler terms for the rest of us laypeople and that's where lies the
potential pitfall of mischaracterization, mispresentation by the pseudoscientific
self proclaimed "New Age Gurus" who exploit them.
What is commonly labelled "medical miracle" i.e
unexplained healing of a disease that doctors cannot explain is not really
a miracle, since no existing laws of EXACT SCIENCE are violated. There
is no LAW in medicine, in the sense of Law of Gravitation, that holds
unfailingly. Medicine is more or less an empirical science. Even
medicine acknowledges the potential of human mind in healing some ailments
which otherwise is judged incurable by routine medical methods. That's
the very nature of empirical science. But the basis of ALL science is the
laws of Physics. Every phenomena is a high level manifestation of Physical
Laws working at the lowest level. Since none of the "medical miracles"
(Which are the only ones whose existence are attested to by doctors/scientists)
which are high level deviations from the norm of empirical science can
be reductively traced to a violation of the basic physical laws at the
lowest level, they cannot be defined to be true miracles.
The same kind of speculative reasoning can be applied to give a
plausibility touch to Jungian phenomenon of "synchronicity". I
must emphasize again that the point is to illustrate that miracle like
events can possibly happen purely out of a naturalistic cause/effect
and not due to a conscious intervention of a divine entity envisaged
in traditional religion/metaphysics. It is possible that some
alternative spiritual healing might work for someone in a specific
instance where traditional medicine failed. This can be due to a
stroke of good luck hit upon by the healer by empirical trial and
error that might work for certain individual under certain
circumstances but which can certainly be not reproducible in a
controlled and predictable way. So the healer cannot claim a
possession of some supreme spiritual healing power/insight for
such isolated instances of success. If the spiritual healing did
unfailingly succeed in 100% cases or if they could unfailingly
PREDICT the success/failure of their spiritual technique on each
subject then that would lend credence worthy of attention and would
have become mainstream healing method by now. Most explanations
of failures are provided post hoc, i.e after the fact, not predicted
in advance. Of course, since there is a certain probability that a
certain individual may be the beneficiary of the isolated
instances of success of the spiritual trial and error healing method,
then he/she can by all means give it a try when all traditional
means turned out to be a failure. Medicine, after all is not an
exact science with unfailing laws like Physics and can never provide
unfailing success in healing on each and every subject in all
ailments.
All the hearsay of miracles are personal (individual or group)
accounts, anecdotes. They can at best be labelled as "truth" as
seen in the eye of the beholder. They have never been demonstrated/repeated
or have happened in an open forum or in public or in a controlled
environment under careful observations. In this context it may be
relevant to mention that the $100,000 award declared by the
debunker/magician James Randi or the Rs. 100,000 award declared
by B. Premanand, the Founder of Indian CSICOP (Committee for the
Scientific Investigation of Claims of the Paranormal), or more
recently, the Rs 2 million award by Prabir Ghose of Indian
Rationalist Association, that if anyone can conclusively
demonstrate the existence of a miracle still remain unclaimed.
What is inexplicable now, if any such event can truly be
verified to exist, can potentially be explainable by discovery
(If we are lucky. Discoveries of Scientific laws are
Epiphanic, not all potential laws of nature are guaranteed to be
discovered) of new or suitable extensions of existing natural
laws in future through increased understanding. In fact some
positivist philosophers insist that there can never be anything
called supernatural in the true sense. Because anything we observe
is a phenomenon, i.e observations WITHIN nature. Anything outside
nature, in whatever sense it may be, must be beyond observation, so
we can have no knmowledge, even speculative, about it, so it is
meaningless to even refer to them. The word "Supernatural" only
reflects our ignorance of the ultimate explanation of the observed
phenomena of nature beyond a certain level. it does not reflect
a breach of nature's rule. Whatever happens in nature, regardless
of how it appears to us, must be due to nature's laws, almost like
a tautological statement. The fact that some magical tricks can
baffle even a very well prepared scientist indicates that it is
even more likely that humans can be fooled by the mother of all
magicians: "Mother Nature". Humanity is making progress in its
effort to decipher more and more tricks of this grand magician in an
incremental way.
The question that has always intrigued philosophers and
thinkers is whether human behaviour is determined by nurture,
i.e through the effect of environment, learning, upbringing,
(in one word cultural conditioning), or by human nature, i.e
by inborn genetic traits that are inherited at birth. The
two extreme positions on this question are environmental or
cultural determinism and genetic determinism. In past, in the
absence of scientific knowledge and evidence, people took one
position or the other based on their gut instincts and
perceptions and were often based on a bias that suited their
political or ideological leanings. Thanks to advances in
genetics, neuropsychology and evolutionary biology, we now know
that both factors play a role, although the genetic factors are
more fundamental than cultural one in shaping human behaviour.
A popular answer to the question: which is important, nature or
nurture is answered by asking the rhetorical question, which is
more important in determining the area of a rectangle, its width
or length? (Implying both are). It is true that both are important,
but unlike the rectangle's length and width, nature and nurture
do not bear such a symmetrical importance in the determination
of human behaviour. Later discussion will clarify this further.
Although vey few today are strictly genetic determinists, there
are still quite a few strict cultural determinists, because
such a biased view suits their political or ideological stands.
There is an aversion to accpet gentic influence on behaviour.
It is curious that even though it has been known for years that
personalities of animals like aggressiveness, docility, agility,
slothness can be varied by selective breeding (i.e gene
manipulation), but when it comes to humans, which after all are
anials too, there is a reluctance in recognizing the gene's role
in determining personality.
A strict environmental determinism is deemed a politically
correct stand, regardless of what scientific evidence indicates.
By assuming a blank slate hypothesis (Tabula Rasa) first
theorized by philosopher Locke, a sense of egalitarianism is
aimed at. That explains for example why Marx taught that many
human characteristics are caused by environmental factors,
which are now known to be inherited through genes. In former
Soviet Union Stalin tried to twist genetics to comform to Marxist
dogma and denied genetic inheritance. A charlatan scientist
named T.D Lysenko was appoinetd by Stalin for this purpose.
When honest scientists like Vavilov pointed out the scientific
flaws of Lysenko's theory, they were sent to the gulag by
Stalin. Teaching of genetics was banned by Stalin because it
contradicted Communist dogma. See
http://www.cyberussr.com/rus/lysenko.html and
http://www.secweb.org/asset.asp?AssetID=238 for more on
Lysenko. Scientific evidence does not support a blanket
nurturist view, the blank slate hypothesis. Even a careful
thinking can expose the inconsistency of a blank slate
hypothesis. If all humans are born with a blank slate,
then how can a mind(brain) learn at all? A blank slate cannot
write on itself or on another blank slate!. The nature nurture
issue is a prime example where scientific insight and evidences
are ignored in favour of a biased politically correct answer
to this essentially scientific question. I will dwell on the
scientific and logical attempt to answer this question. Most
of my discussion is based on the insights gained from
evolutionary psychology by reading various books by
psychologists, biologists, neuroscientists, and science
journalists. I will quote from some of the books, not all.
We can represent the effect of environment and gene through a
visual aid as shown diagrammatically below.

In the above diagrams the outer shell region (marked by ".")
indicates effect of environment, learning, upbringing etc
(nurture). The central core (marked by "*") indicates the
genetic influence (nature). I refer to mind and brain in an
interchangeable sense consistent with the paradigm of
contempoorary psychology, which views mind as a sort of
program running on the brain as the hardware, the programmer
being the blind laws of evolution.
In biological parlance the inner core represents the genetic
propensities coded by the rules of epigenesis (i.e the rules
of how the basic architecture(i.e the neuronal circuitry and
synaptic connections) of an individual mind/brain is formed,
which in turn is determined by genes. So the basic architecture
of human brain is formed early on in infancy by the rules of
epigenesis, which is represented by the core. The shell represents
the effects of environment, i.e culture and learning, which causes
additional neuronal wiring in the neocortex area of the brain
througout one's lifetime. Although the shell (Which are the
synaptic connections of neocortex formed by neuronal firings
triggered by environmental stimulus) is formed by environment,
the nature of the shell is in turn determined by the core, i.e
the epigenetic rules themselves. In other words although
environments do shape a human behaviour to some degree,
it does not shape it identically for everyone. Similar
environmental stimulus will evoke different behavorial response
in different human (due to different epigenetic rules). In other
words, even though it is true that many traits are shaped by
environment, how a given environment shapes a given trait is
determined by genetic factors. This is clearly described in
the book "Are We Hardwired" by eminent biologist William Clark.
He says on page-20, refering to the three processes of
behaviour, viz, (1) perception of environmental stimuli, (2)
processing of perception with stored memory, and (3) responding
to environmental stimulus, he says: "Naturally ocurring
differences between individuals in the genes regulating
any of these processes may well explain differences in the
way different people react to the same external situation".
Also to quote MIT psychologits Steven Pinker from page 102 of
his book "The Blank Slate: The Modern Denial of Human Nature":
A nice metaphor to illustrate this fact is a computer program
whose output is determined by both the input and the program
structure(code). The same program code will produce different
outputs for different inputs, or two different programs will
produce different output for the same input data. Both the
program structure and input data together determine the output
result. Thats why even under identical environment two humans
would still have different moral values. It is also very
important to take note of the fact that certain traits are
entirely genetic and not shaped by environment. In the computer
metaphor, this is equivalent to saying that certain outputs of
the program are generated solely by the code without needing
any input, and are not changed by whatever input is fed to it.
Studies of identical twins corroborate these conclusions on the
effect of gene in many traits. As William Clark points out in
pages 18-19 in "Are We Hardwired?" that identical twins, whose
genes are identical, show remarkable similarity, even when
reared apart, and maintian that similarity for a long time.
He also points out that for identical twins, the effect of genes
in bringing about similarity between them reared in different
environments is much greater than the effect of the different
environments in bringing about the differences between them,
or that the contribution of genes in the similarity between
identical twins reared in a common environemnt is much greater
than the conribution of the common environemnt in the similarity
As another example, Steven Pinker mentions
on p-20 of his book "How the Mind Works" that Identical twins
study corroborate gene's strong influence on traits. He also
mentions on page-47 of "The Blank Slate" that Identical twins
have similar views on death penalty, religion (and controversial
values), their EEG crags and valleys are alike and that virtual
twins, two unrelated siblings brought up in identical
environments, are like night and day.
Pinker also points out that twinning and adoption are natural
experiments that offer strong indirect evidence that
differences in mind is due to differences in the genes.
So to summarize, some humnan traits are determined by genes,
others by a combination of gene and environment. Traits are
seldom determined solely by environment, although it is
possible that certain behaviours can be solely determined by
environment. Traits are natural expressions of genetic
propensities. Propensities are always prescribed by genes. As
sociobiologist and Pullitzer wining author Edward O. Wilson
says on page-89 of his book "In Search of Nature":
According to lessons from contemporary sociobiology the
following sequence describes the relationship between nature
(gene) and nurture(culture) : gene(prescribes) the epigenetic
rules, i.e the rules of how the basic framework of an
individual mind is formed, and the individual mind in turn
grows further through cultural influence (neuronal wiring), and
in turn shapes culture. So its tightly coupled relationship and
is called gene-culture co-evolution.
There is an internal inconsistency in the nurturists' assertions
like "human are not born evil. They are made evil by bad
environment". The implication is that environemnt is some
autonomous being external to human mind. But the fact is that
environment is made up of humans, or is a product of humans(brains).
For environment to be bad, the humans who make up that environment
have to be bad in the first place. Its not a chicken and egg problem.
Human nature itself gives rise to environment. In a sense an
environment is the totality of all human brains that exert
influence on an individual brain that they surround, in a certain
community of people. So enviroment is ultimately a product of the
gene pool of that community.
Again to quote sociobiologist E.O. Wilson from the chapter titled
"Culture as a Biological Product" in his "In Search of Nature":
"To summarize this point, culture is created and shaped by
biological processes while the biological processes are
simultaneously altered in response to cultural change." and
"Culture is rooted in Biology. Its evolution is channelled
by the epigenetic rules of mental development, which in turn
are genetically prescribed." (p-110)
"Culture is deeply rooted in biology. Its evolution is channeled
by the epigenetic rules of mental development, which in turn
are genetically prescribed. We can envisage the full chain of
causation from genetic prescription to the formation of culture
and back again through natural selection to chnges in gene
frequencies" (p-126)
Wilson also points out that even the epigenetic factor is
prescribed by the gene and thus different individuals posses
different epigenetic rules, i.e although environment does play
a role in the development of an individual human(mind), the
effect is different for different individuals under identical
environment, culture etc. In other words genetic propensities
are modulated by the environment. For example "Sex on the Brain"
, author Deborah Blum says that "Gene determines the baseline
testosterone in male and females. Environment adds the
fluctuation around the baseline".
When we say that a certain behaviour of an individual is due to
environment, not due to his gene, the true significance of this
statement is hidden behind semantics and may not be realized by
even those who make such statements. What it means is that the
behaviour in question is not caused directly by HIS/HER
individual gene, or a complex of genes.
We have to distinguish between proximate vs. ultimate cause of
actions and behaviour. A gene can be a proximate cause of
behaviour when the behaviour is a direct result of a gene or
complex of genes in the DNA of that particular human. But a
gene can also be an ultimate cause of behaviour when the
behaviour is shaped through the cumulative effect of gene-
culture coevolution happenning within the gene pool from past
upto the present when the behaviour in question has occurred.
Put simply, when we say the gene is responsible for a behaviour,
what is meant is that it is only the gene of the individuals'
DNA in action that is causing that behaviour. When we say that
environemnt is causing the behaviour, what is meant is that it
is the aggregate genes of the gene pool of the community,
coevolving with the culture over an evolutionary time scale to
produce that specific environment/culture which causes that
behaviour. Gene is still at the bottom in both cases, only the
mechanism is direct in one case, and indirect(evolutionary) in
the other. Again it may be relevant to quote Steven Pinker form
page 69 of "The Blank Slate": "History and culture can be
grounded in psychology, which can be grounded in computation,
neuroscience, genetics and evolution." All organs of human (or
any animal) are shaped by evolution. Brain, as the most complex
organ, certainly evolves too. And since behaviour is linked
with brain, human behaviour is ultimately governed by evolution.
And evolution in turn is determined by the biological
imperative of the maximal replication of genes via mutation and
natural selection. So there is a gradual hierarchical layers of
causation from higher to lower levels.
There are other obvious flaws in the nurturists' insistence that
human values and behaviours are learned and taught, not inborn.
This is not strictly true. Many traits, behaviours are due to
inherent propensities. For example, as Steven Pinker says on
page 44 of "The Blank Slate" that "Intelligence,
scientific genius, sexual orientation and impulsive violence
are not entirely learned." And on page 51 Pinker says that
"Genetics and neuroscience are showing that a heart of darkness
cannot always be blamed on parents or society." If learning
could influence or shape human behaviour or traits then
psychopaths could be cured. But they cannot be, as Pinker says
on page 263 (op cit) "Psychopaths cannot be cured". And on p-315
Pinker reiterates that "There is little doubt that some
individuals are constitutionally more prone to violence than
others". Another classic case provng that dark sides of human
behaviour is not really learned or culturally shaped is that
of Jack Abbott. Pullitzer author Norman Mailer freed the
prisoner Jack Abbott from the jail, after being impressed by
his letters written to him, which were published by
Mailer as a book in 1980 titled "In the belly of the beast",
fetching a Pullitzer award for him. Abbott was also treated as
a celebrity and feted at literary dinners. Two weeks later, he
stabbed a waiter in a restaurant on an argument on not using
the employees restroom! (cited in Pinker - Blank Slate, p-262).
Many cultural determinists argue that sexual abuse by
many are due to the abusers themselves being victims of sexual
abuse in their childhood. This is not true necessarily. Joan
Allen Rodgers in her book "Sex: A Natural History" says that
there is evidence that many who sexually abuse children have no
history whatsover of abuse in their own lives. And on p-429 she
quotes geneticist Fred Berlin and says that deviant sexual
behaviour (sexual paraphilia) also cannot be taught, but is
rooted biologically, but hastens to add that society must
punish such acts to protect victims, but should not preclude
study and understanding of such behaviours. Steven Pinker on
page 311 of his "The Blank Slate" cites the fact that Canadians
watch the same television shows as Americans but have 1/4 the
homicide rate as US, debunking the allegation that violent TV
shows teach violent behaviours.
Pinker also questions the common belief that children learn
violence while growing up by external stimulus. On page 316 he
mentions that "children are violent well before they have been
infected by war or toys or cultural stereotypes. The most violent
age is not adoloscence, but toddlerhood." He also quotes from
C. Holden in "The violence of the lambs", Science, 289, 2000,
pp-580-1 :
One of the bitterest lesson of parenthood is that children don't
always turn out the way their parents want. It shows again
that not anything that is taught will be learned. People will
learn more easily if what is taught is favoured by their
genetic propensity. Some parents may teach something that is
not in their genetic propensity, for example a parent may, for
practical reasons try to teach medicine or engineering to his
child although his own or his child's genetic propensirty is
for arts. That is not guaranteed to succeed.
Now let me come back to the reasons for holding a strictly
cutural determinstic (i.e blank slate) view. One reason that
many who reject "nature" do so because an nature view has two
uneasy implications. For one thing they are afraid that then
any act can be justified as being genetically programmed and
hence beyond one's control, and thus would preclude any
accountability for a wrong act. This logic can cut the other
way too. If an action or behaviour is deemed as strictly
environmentally determined then also it is beyond one's control
and can equally deserve to be exempt from accountability.
Adopting cultural determinism does not provide any adavantage
over genetic determinism as far as accountability is concerned.
Secondly it is feared that admitting genetic determinism can
justify human inequality due to genetic superiority in talents
and other traits of one human over another and seems to go
against the notion of egalitarianism, which was the motivation
for rejecting genetics by Marx, as discussed earlier in this
essay. But these are all misdirected concerns. Human equality
should not be based on identity of genetic traits and qualities.
Any system or ideology, whether it is communism or whatever,
should be judged on its own merit for its acceptance or rejection,
it is dangerous to justify or base any ideology on an assumption
that is unproven, or is contrary to scientific evidence.
Equality (in rights) is an important universally acknowledged
humanistic ideal that should not be contingent on any other
assumption. As biologists Earnst Mayor says in his book
"Animal species and evolution" that equality should not be
based on claims of identity, since if latter is disproved, the
former is lost. (quoted on p-146 of "The Blank Slate - Pinker).
This is true for gender, racial or other equality (in rights)
as well. The saying "All human are born equal" should really be
phrased as "All human are born equal in their rights". They
need not be born equal in traits and qualities like talents,
moral judgements etc. Equality between every human in their
genetic potentials (whatever criteria is used to measure them)
is a biased opinion that is not based on scientific or logical
grounds.
Also the fact that some act or behaviour is explained as
genetically programmed does not (and should not) necessarily
translate into a "sanction" of that act. Explaining is not
exculpating. Describing is not prescribing.
As Wilson warns on p-93 of "In Search of Nature" against
naturalistic fallacy, i.e the fallacy of assuming what is,
should be. The "what is" in human nature is to a large extent
heritage of a Pleistocene hunter gatherer existence. Wilson
points out that the demonstration of a genetic bias cannot be
used to justify a continuing practice in present and future
societies.
I quoted Fred Berlin earlier who also emphasized punishment
as deterrent to protect victims from sexual deviants, but
also emphasized understanding of such deviant behaviour.
Genes in our body issue orders, so to speak, but we can disobey
their orders. Many of these orders served their purpose in our
evolutionary past and exists in us as a vestigial reminder of
that time. Much of it may not or does not have much value in the
present time, excpet for some basic biological imperatives. A
punitive or preventive act in response to a wrong act by another
is also in our nature as one such imperative and acts as social
deterrents against such acts. This provides the necessary checks
and balance for natural selection process to maintain an evolutionary
stable equilibrium in a species and helps it to survive and
propagate. So just because one understands that an intruder is
acting on his genetic impulse does not mean one will sit back and
welcome the intruder. He would fight back to drive the intruder
away and protect his property. This is a defensive biological
imperative of human (or any animal for that matter) and cannot
be overrridden by any biological insight into human impulses. Now
let us look at the other side of the coin. If altruism is also
explained as a natural instinct, not cultivated or learned,
does it mean that we should not appreciate altruism as a human
virtue anymore? After all, what we call altruism, is known from
the insights of sociobiology as nothing but a mechanism for
selfish genes to maximize their replication through what is
known as kin selection. Whether to appreciate altruism, is a
judgement call. There is no "should" here. It is just that
appreciating altruism is also in our nature. Because not all
humans adopt altruism as the means of selfish replication of
the genes. Altruism is not commonplace. The cynical assertion:
"There is no true altruism. An altruist is also driven by selfish
desire to get gratification through altruist acts" is a hollow
assertion since the gratification comes only AFTER the act of
altruism as an effect. An effect cannot be the cause of an action.
It is true that one knows beforehand that the gratification will
follow an altruitsic act but that is only in hindsight from a
previous experience of altruism and is used as foresight
therafter. So the root cause of altruism is not the desire for
gratification. The root is in one's genetic makeup. So although
altruism is rooted in one's nature(genes), and not due to one's
conscious choice (conscious choice does not exist in isolation
from the genes, rather it is a manifestation of the underlying
genetic makeup along with the interaction of that genetic
makeup with environment), its nevertheless something to be
appreciated and valued. After all, not all selfish acts benefit
others. Altruism, if it is a selfish act at all, is one which
benefit others. The real insight comes from recognizing that
altruism has an evolutionary value in terms of gene propagation.
We humans instinctively value traits that are evolutionarily
advantageous.
The second reason many reject nature because that seems to
legitimize an uneven playing field and attribute the misery
and failure of one segment of society (A) to their own inherent
limitations as well as attribute success and happiness of
the other segment(B) to their inherent natural advantages. A
naturist stand prevents "A" from falsely blaming B for A's
misfortune. On the other hand by insisting on nurture it
relieves A of accepting any responsibility for their misfortune
and makes it easier for them to blame society (B) making them
scapegoat for not providing the proper nurturing and causing
their misfortune. But this can cut both ways. If a nurturist
position is adopted, then in a zero discrimination society,
the poor will be blamed for their fate by choosing not to utilize
the potential, whereas if innate differences are acknowledged,
then in a zero discrimination society, poors cannot be blamed
for not utilizing their potential to the full. Of course,
nature or nurture, zero discrimintaion society is a must.
It is a humanistic imperative that follows from the equality
(of rights) of all humans. Whether to enforce an equality of
properties and priviledges between humans in an equal rights
(zero discrimination) society, where unequal properties
and priviledges can arise due to innate differences of human
abilities and potentials, is a political and social judgement,
it is not mandated or forbidden by scientific evidence.
It is appropriate to examine the profound questions like what
is Life, how did it originate, what is the purpose of life, why
we die, is there life after death etc from an alternate angle,
not based on faith like religious views on afterlife, soul, day
of judgment etc is, nor based on armchair philosophy weaving a
tapestry of verbiage, but based on the hard earned insights gained
through scientific observations and scientific thinking that has
revolutionaized and continues to revolutionize our worldview and
paradigms. It must be understood in clear terms that scientific
insights are consensus based as they are rooted in objective
evidence and rational thinking and hence crosses cultural,
religious and racial boundaries, not the product of any specific
culture or bias. These are old questions although the meaning
of the questions (and of course the answers) have changed over
the years in view of a wealth of insights gained thanks to
the revolutionary way scientific thinking has changed human
perceptions and knowledge and the remarkable discoveries and
insights that it has led to and is still leading to. To briefly
phrase the best known scientific answer today in scientific
jargon : "Life is a dissipative structure that has achieved
the threshold of complexity to become an autopoietic system
operating on the edge of chaos, capable of evolution via
variation and natural selection". A dissipative structure is
a far from thermodynamic equilibrium system that tends to
maintain it's identity by ccyhannelizing a continuous flux
of energy through it. Living systems accomplishes this by
absorbing the high grade solar energy, decreasing its own
entropy (Or increrasing its local order), but releasing more
enetropy to the environment through low grade heat energy and
thus decreasing the overall order of the universe. Autopoietic
systems are autonomous and self-generating systems, i.e they
can make copies of themselves without an external agent by
autocatalytic process and transducing energy from the environment.
The underlying purpose of life is to to faithfully obey the
Second Law of Thermodynamics by increasing universe's entropy.
Even eating and sex are dictated by this requirement, although
our brain translates it into a sense of desire and pleasure for
us, causing us to replicate, hiding the real underlying purpose
from our conscious mind. So the purpose of life, viewed from
level above that of the laws of thermodynamics, is to make more
life of the same kind. Our desire to live, mating urge, hunger is
nothing but a higher level manifestation of that purpose rooted
ultimately in the laws of physics at work at the cell level. Why
do we die? In short because we (i.e most plants and animals) have
inherited through evolution death genes from our protist(single
celled organisms with nucleus) ancestors who took to sexual
reproduction as a better evolutionary survival strategy in tough
primitive environments. Death is brought about in a programmed
way (called programmed cell death or apoptosis) by certain genes
(death genes). Those few life forms (bacteria) that did not and
still do not reproduce sexually are immortal, barring accidental
deaths (like antibiotics). Death is the price that higher life
forms pay individually for the better survival strategy of their
species. Without death harmful mutations would have been passed
on to the offsprings without limit and potentially destroyed the
species as a whole.
Let me dwell on the scientific nature of death itself. It is
true that irreversible death inevitably follows the stoppage of
brain, heart etc, but that is not the fundamental cause of death.
The fundamental cause of the death of an organism is the death
of a critical number of cells in any vital organ. Cell is the
lowest level of the cause of death. Otherwise there will be a
circularity in saying that the cell dies because heart stops
pumping blood, and the heart stops because of the death of
cells etc. Cells die primarily due to lack of oxygen (through
blood supply). If enough number of cells die in any vital
organ (heart, brain, kidney,..) due to accident (which includes
serious disease) or due to aging (programmed death cell), the
heart may have trouble pumping blood smoothly, and thus the
heart cells may themselves begin to die, and the process of cell
death is precipitated in all the organs quickly leading to the
irreversible death of the entire organism. It is possible that
one's brain cells may be dead beyond repair but the heart cells
may be kept alive through life support, and hence the entire
organism may be assumed to be alive, but brain dead, a state
known as PVS (Persistent Vegetative State), like the women in
Florida. It is a matter of semantics and bioethics whether such
state can be called dead or alive. Semantics or ethics aside,
biologically it is known exactly what the state is. The cells
of any organ except the brain has some resiliency where they
can stay alive for some time even after the supply of oxygen
has stopped and can be restored to life by resuming oxygen
supply by whatever means. But brain cells cannot survive
without oxygen, and die almost immediately. There is some problem with
life being defined solely in terms of the functions of vital organs (at
level higher than the fundamental unit of cell), that is an effect we
see in larger organisms due to the combined effect of individual cells.
The definition of life should also include bacteria, and they don't
have those organs. Some thus define life as the effect of cell or cells
carrying out metabolism. But even that definition has some problem.
What about spores and cysts, and viruses? They don't have metabolisms
and can remain latent for centuries and can come alive when proper
conditions (water and nutrients) become available. This latent state is
called cryptobiosis. Viruses become alive (i.e starts replicating
itself) when it finds a host cell. So molecular biologists have gone
even deeper. What is in a spore, cyst etc that brings it back alive and
not any other object of the same dimension? It is in the MOLECULAR
ARRANGEMENT of the cell, which is in turn prescribed by the code in the
DNA. As long as that molecular arrangement is preserved a cell has the
potential to come back to life. If a spore or cyst is bombarded with
excessive radiation (by humans of course, because spores are designed
to deal with all natural adversities), the spores and cysts lose that
molecular structure and will not come back to life even after being
provided water and nutrients. So life ultimately resides in the
molecular structure of a cell, as prescribed by the code of the DNA.
More interesting example is in the multicellular embryo of brine shrimp.
These shrimps breed in the highest saline water, and in dry season
their embryo stops developing and goes into the cryptobiotic state,
like the spores and cysts. Only when the salinity decreases after rain
or water from any source will the embryo resume development and hatch
finally. But the cryptobiotic state can last indefinitely. The last
interesting point I would like to bring up is the programmed death of
cells, which is the reason that we all are mortal, even in the absence
of any disease and nutrition. Aging is due to a senescence clock in our
somatic cells. The germ cells never die, they are passed on through
sexual reproductions forever. It is the death of the somatic cells (
which make up all our body organs and thus our body, mind, brain) which
cause our death. And somatic cells have to die to give the germ cells
immortality. It is a mutually exclusive trade off. The details of the
arguments lie in molecular biology. I cannot describe it in few lines.
It is subtle, fascinating and profound. I will suggest very good
reference, "Sex and the Origins of Death" by UCLA molecular biologist
William R. Clark. It is a fascinating read. I highly recommend it to
all interested in the ultimate question on life and death. Anyway the
somatic cells have the gene for death (the death gene) which is turned
on by the alarm bell of the molecular clock that is ticking in each
somatic cell. Usually this happens aftre a somatic cell has underfone
50 mitotic divisions. But it is also possible that the death genes of
some somatic cells can be switched off permanently my malignant
mutations, as in a cancerous tumor. These cells become immortal!.
Unless met with accident or starvation thay will divide and multiply
forever. A classic case is that of Henrietta Lacks, a Baltimore woman
who died in 1951 of cervical cancer. The doctors took out her part of
her tumour. The cells in her tumour have the death genes switched off
permanently. Her living cells are now happily residing in the labs
around the world today, and will live on forever as long they are kept
in favourable conditions. Her cells are called HeLa cells after her
name. The total biomass of HeLa cells today have exceeded her own body
mass!
Now let me try to address the most complex question of how life
originated by outlining it in 5 steps that reflect the current
scientific insight. I must emphasize that there still remains a mystery,
the ultimate one (denoted by "?" in the following) which we will never
know, because that truly belongs to the category of the unknowable.
The second scenario is due to some versions of Cosmology which
derives Big Bang as a consequence of laws of physics (Quantum
Cosmology). Anyway, we can say for sure that there IS an
ultimate mystery, since we don't know from where did the Laws of
Physics (Quantum Field theory to be precise, which is at the
bottom of ALL laws of Physics) came from, or why is there a law
of physics? Strong atheists believe that there is no "?", laws
of Physics are the ultimate reality, self-caused, there is
nothing beyond our phenomenal world. In other words they claim
that "?" is NOT unknown, but it is known and is = NULL, i.e
nothing. That is as much a belief as it is to assert that "?"
is not NULL, that there must be "something" above the laws of
Physics, being the cause of it. But to believe that "?" is not
NULL in itself does not mean theism, because theism is a
cognitive assertion that asserts "?" = THIS (Replace "THIS"
with the God of each religion), but to say that ? is "something"
unknown is a noncognitive statement. Anyway, we don't need to
go any further into this metaphysical issue for the rest of the
discussion.
Let me cite some quotes of various scientists in support of the above
scientific insight, as it is not possible for me to list all the
scientific facts of each area to justify this view, except to note that
most chemistry books devote their first few chapters on the physics
of atoms and molecules, and most biology books devote their first
few chapters on organic chemisrty. Nobel Laureate Watson of
DNA fame said "In the last analysis, there are only atoms. There's
just one science, Physics; everything else is social work" in
his lecture at the London Institute of Contemporary Arts in 1985.
This view is also echoed by Stephen Hawking and Steven Weinberg.
Hawking nicely summarizes this view as: Biology->Chemistry->
Physics, in the book "The Large, the Small and the Human Mind".
Steven Weinberg says in his book "Facing Up", p-22-3: "No biologist
today will be content with an axiom about biological behaviours
that could not be imagined to have a more fundamental level.
That more fundamental level would have to be the level of
Physics and chemistry, and the contigency that the earth is
billions of years old". Biologist Richard Dawkins (in "The Blind
Watchmaker") states that Physicists have to come into the scene
at the end of the long chain of reasoning to explain evolution
of life to complete the last but not the least significant step.
Molecular Biologist Frankln Harold says in his wonderful book
"The Way of the Cell", p-4: "We have ample reason to believe
that every biological phenomena, however complex, is ultimately
based on chemical and physical interactions among molecules"
and reinforces this in his epilog : "The bedrock premise of this
book book is that life is a material phenomenon, grounded in
chemistry and physics. Physicist Heinz Pagels wrote in his book
"The Dreams of Reason", p-49: "Biological systems are extremely
complex Quantum mechanical entities functioning according
to well-defined rules". Zoologist and award winning science writer
Colin Tudge says (Independent on Sunday, Jan 25, 1998): "There are
no biological laws, apart from the underlying laws of physics,
and technology might anything that does not break these bedrock laws".
In the book "Our Living Multiverse: A Book of Genesis in 0+7 Chapters",
alternately titled as "Origins of Our Existence : How Life Emerged in
the Universe" author Fred Adams (Univ. of Michigan Physics Professor)
writes:
It is important point to note that above is a very high level
flow diagram. The details for each arrow are incredibly complex,
there are unsolved problems galore, and thats where scientists
are working hard on filling out the details, and the complete
mechanism of the origin of life is not known yet, but again,
that is a scientific problem, not a metaphysical one, and is in
principle scientifically solvable, we are getting closer and
closer to the solution. In fact the problem of the origin of life
is not that there is not any satisfactory theory, but that there
are too many possible theories. The laws of Science only impose
some constrains on what the theories can be, but it does not
uniquely select and decide which theory is the correct, since all
these theories are plausible explanations of life. The fact that
we do not completely understand life yet does not imply that it is
not understandable in physical terms. We don't understand weather
too, in spite of all the technical advances. This lack of understanding
is rooted in the complexity of both weather and life. The chain of
reasoning based on laws of physics that links a simple molecule
to a living organism is broken in the middle due to the enormous
complexity of cumulative effects of historical contingencies
that are acted upon by the laws of complexity, over billions of
years of evolution. In weather, it is the enormous number of air
molecules that is at the root of complexity preventing an exact
understanding. Anything after the "?" (i.e after the Big bang)
is within the domain of science (Phenomenal world), and we can
only talk about unsolved problems, not mysteries within this
domain.
In other words our minds and consciousness have discovered (through
scientific methods) the very same physical laws that created
it(consciousness) in the first place through creation of matter,
life and evolution!
"What science knows of the nature of life, it owes to the labors of
countless specialists---physicists and chemists, mthematicians and
geologists, geneticists and biochemists and physiologists, biologists
evolutionary and biologists molecular. The fruits of our labors are
first inscribed in shelf upon shelf of professional journals, and
subsequently reincarnated in textbooks that have grown too heavy
to carry, let alone be read" (From preface p-x)
For us, not actively engaged in this quest, the only way to
learn about the insights that have been achieved in the search
for the answer to the question of life is through reading the
tales told by scientists themselves or retold by philosophers
of science. Evolution has been called the greatest story ever
told. It may be frustrating to realize that despite reading enough
in one's life time, one can still only hope to get a glimpse, a
fraction of the whole truth. But learning about the truth is
a journey, and its the journey, not the destination that should
give meaning to our finite life.
Greek philosopher Socrates said "know thyself" The emerging new
discipline called evolutionary psychology is just trying to do
that. Through this scientific discipline humans are trying to
reflect on itself and gain knowledge about the way they think,
act and behave. Evolutionary psychology is an attempt to
understand human mind based on objective evidences and
observations using the insights of evolution. It does so in a way
devoid of the vague mysticism, verbosities (that eventually end
up in circularities) that were typical of past endevours to do
the same. This new field is trying to offer credible explanations
for the way we feel, think and behave, form moral judgements and
values in the light of evolutionary principles. An important
subfield of evolutionary psychology is the new field of
neurotheology, which attempts to explain the ubiquitous
religious belief among the human species across all cultures and
race, in the light of the evolutionary working of the brain and
genetics. The fact that religious beliefs and mystical feelings
are rooted in the evolutionary biology of the brain is well
established from neurological research now. Both mysticism, a
form of religious experience and traditional religious beliefs
are rooted in the neuronal substrate of brain consciousness.
Mysticism involves mostly the limbic system of the brain. More on
that later. It seems common sensical today to biologists and
science savvy folks armed with the knowledge of evolution that
like all human traits, religious beliefs must also be a product
of evolution, to increase the odds of survival of the human
species. It would not have been so obvious before evolution was
known. But even as far back as 1899, John Fiske, the American
philosopher said in his 1899 book "Through nature to GOD" : "
Would it not be strange if suddenly, after humans crossed the
magic threshold to speech and self- awareness, the appearance of
religion in all primitive cultures would have had no survival
value?" (From p-381, The Whys of a Philosophical scrivener -
Martin Gardner). A remarkable insight for his time. More recently
Matthew Alper in his book "The God part of the Brain"
(see http//www.godpart.com/premise.html) has argued very cogently
in favour of a God module in our brain, much like Noam Chomsky
suggested a language module in our brain 40 years ago. He
proposes that beliefs in God, the afterlife, mind-over-matter
and superstitions have a physiological origin and may be encoded
into human DNA, evolved as a defense mechanism to help people
cope with the anxiety that comes from being aware of our own
mortality.
The late Eugene d'Aquili, a pioneer in neurotheology, suggested
neuropsychological mechanisms behind the universal existence of
religions and behaviors involving a brain structures performing a
specific function. That structure generates(Or explains) reality
for us when our senses cannot. Gods, spirits, etc. are then
automatically generated by our brains, even if we cognitively
reject the idea of their existence, we still experience them in
our dreams and fantasies, ie, our subconscious. This is a
universal human trait - of believers and non-believers alike.
A result of the actions of this brain area is the construction of
myths and power sources to explain our existence and orient
ourselves within the universe. This allows us to deal with the
world in ways we know how. d'Aquili proposes that this aspect of
religion is a means of controlling our environment
psychologically so that we can control it externally and
ultimately survive in it. So ultimately it is the evolutionary
survival strategy that creates this religion module in the brain.
Modern evolutionary biology views human brain as an evolved organ
just any other, crafted by the selection pressure of evolution.
Thus the manifestation of the working of the brain, i.e mind is
also a product of evolutionary pressure. The way humans think,
behave and feel is shaped by the forces of evolution, acting over
time. It is an illusion to believe that "we" the humans create
the values, morals etc. There is no "we" outside of the brain
existing independently and controlling the brain. There is no
"soul", controlling the brain. The brain controls how humans think,
behave and feel, and the brain itself is controlled by
evolutionary forces, which ultimately is the result of the laws
of Physics at work acting together with the contingencies of
nature(environment). (Please refer to my earlier essay: "Soul,
Brain and the Laws of Physics at:
Neurotheologists are trying to explain spirituality in terms of
neural networks, neurotransmitters and brain chemistry. A general
consensus view of what creates the transcendental feeling of
being one with the universe is that it may be due to the
decreased activity in brain's parietal lobe, which helps regulate
the sense of self and physical orientation.
As far back as 1980, A. Mandell in the article "Toward a
Psychobiology of Transcendence: God in the brain", in
"Psychobiology of Consciousness", was already talking about
the neuronal basis of mystical experience.
A more recent article in Time Magazine of Aug 4, 2003 cites the
studies of Dr. Gregg Jacobs of Harvard, showing that meditation
produces enhanced theta waves, deactivates frontal area and
lowers activity in parietal lobe leading to feeling of oneness
(Unitarity), a common experience reported by all mystics.
v
Andrew Newberg, a pioneer in neurotheology, who worked with
another pioneer, the late Eugene d'Aquili, and with him wrote
the book "Why God Won't Go Away." , says: "The brain is set up in
such a way as to have spiritual experiences and religious
experiences,". In other words the notion of God is hardwired in
human brain.
In their research Newberg and his team found that during
meditation, part of the parietal lobe of their volunteer
meditators was much less active than when the volunteers were
merely sitting still. Newberg and d'Aquili realised that this was
the exact region of the brain where the distinction between self
and other originates. and the sensory deprivation of the parietal
lobe makes the person feel that the boundary between self and
other begin to dissolve. And as the spatial and temporal context
also disappears, the person feels a sense of infinite space and
eternity.
Newberg has repeated the experiment with Franciscan nuns in prayer,
showing the same pattern of shutting down the same regions of the
brain that the meditators did as their sense of oneness peaked.
The sense of unity with the Universe is accompanied by a feeling
of awe and deep significance. Neurotheologists believe that this
sensation originates in the limbic system, also known as the
"emotional brain" in common parlance, that lies deep within the
temporal lobes on the sides of the brain.
The limbic system is the more ancient part of the brain in the
evolutionary sense than the parietal or frontal lobe. During an
intense religious experience, researchers believe that the limbic
system becomes unusually active, attaching great significance to
everything around them during such time
When neurosurgeons stimulate the limbic system during open-
brain surgery they say their patients occasionally report
experiencing religious sensations. Not surprisingly Alzheimer's
disease which tends to impair the limbic system, is accompanied
with a loss of religious interest.
There is evidence that the limbic system is important in
religious experiences. People who suffer epileptic seizures of
the limbic system, or the temporal lobes in general, sometimes
report having profound experiences during their seizures. Jeffrey
Saver, a neurologist at the University of California, Los Angeles
says. "This is similar to people undergoing religious conversion,
who have a sense of seeing through their hollow selves or
superficial reality to a deeper reality,". He says that
epileptics have historically tended to be the people with the
great mystical experiences.
The limbic system is hardwired by evolution to evoke a belief
in deity to cope with the severe stress and insecurity that a
crisis can bring about. It is a purely evolutionary adaptation
for survival, much like the reflexive retreat of our hand from
a red glowing object, or our reflex on seeing a snake like object
in dark etc. Rational thoughts from our cortex area loses control.
At that time all humans revert to raw animal reflexes, blurring
the distinction between theists, atheists etc that are results
of the difference in neural connections in cerebral cortex due
to both both genetic differences as and differences in
environmental effect of upbringing.
This reflex action of our brain via limbic system is
responsible for providing us an artificial consolation of a
protector to get past the crisis without suffering a heart
attack. Whether the crisis ends in eventual catastrophe or in
an eventual clearing of danger does not depend on the state (Or
a change in state) of the belief of the distressed people. There
has been more than one incidents of disasters, plane crash,
shipwreck with religious people on board (A Saudi plane crashed
with Hajj pilgrims all dying in the crash sometime ago). Hence
the hard wired reflex causing an atheist to instinctively switch
belief in moments of severe crisis does not prove at all that God
exists. It only reinforces the fact that the feeling of "God" is
hardwired in the brain.
Neurotransmitters can also stimulate mystical experience, besides
sensory deprivation of the parietal lobes or the electromagnetic
stimulation of the temporal lobes. Psychiatrist Roy Mathew of
Duke University has studied hallucinogenic drugs that can produce
mystical experiences and have long been used in certain religious
traditions, for example the "Soma" used by ancient Hindu ascetics.
Perhaps no other neurotheologists have gone to the length that
Michael Persinger, a neuropsychologist at Canada's Laurentian
University in Sudbury, Ontario has gone. It may seem to be
trivializing the divine, but essentially he has devised his
virtual spiritual helmet to experience God (He calls it "sensed
presence") at one's calling. Persinger has been using stimulation
of the temporal lobe of his subjects using a technique called
transcranial magnetic stimulation (TMS) to stimulate a wide
assortment of experiences, some surreal (The New Scientist, 19
November 1994, p29 carries a detailed account of it)
With a series of Electromagnetic pattern he calls the Thomas
pulse, he can stimulate in the subject wearing the helmet to a
sensed presence (Of something divine), something similar to the
fruition of the lifetime goal of an ancient mystic to unify with
the divine.
The 900 or more subjects that Persinger has tickled the temporal
lobes of, labelled this perception of sensed presence with the
names that reflect the culture that they have been reared in -
Elijah, Jesus, the Virgin Mary, Mohammed, the Sky Spirit etc,
while agnostic UFO enthusiast talk of having experienced alien-
abduction! If a loved one has recently died, they may feel that
person has returned to see them. "This is all in the laboratory,
so you can imagine what would happen if the person is alone in
their bed at night or in a church, where the context is so
important," Persinger says.
Persinger has extrapolated his research on the effect of
Electromagnetic (EM) fields on the temporal lobe of individual
subjects to the effect of natural fluctuations of EM field due
to natural events like earthquake, (i.e techtonic strain), solar
flare, meteor shower or due to even man made effect like building
a huge dam, oil drilling etc can lead to mass hallucinatory
perceptions. For example, the classic case of the apparition of
Mary over the Coptic Church in Zeitoun, Egypt, in the 1960s which
lasted off and on for several years, and seen by thousands of
people, seemed to precede the disturbances that occurred during
the building of the Aswan High Dam. There were multiple examples
of reservoirs being built or lakes being filled, and reports of
luminous displays and UFO flaps abounded then. He has also
published a paper called "The Tectonic Strain Theory as an
Explanation for UFO Phenomena," in which he maintains that
around the time of an earthquake, changes in the EM field
could spark mysterious lights in the sky.
Many books and papers have appeared based on the results of
neurological research that are reinforcing this new paradigm of
the neuronal basis of religious beliefs.
On page 15 of their book "Where God resides in the brain"
authors Allbright & Ashbrook states: "Humans are meaning seeking
animals. Faith is built into the activity of our biology, our
nervous systems, our neurocognitive processes, our humanizing
brain"
Neurologists are now convinced that every belief/propensity
etc are mapped into specific neuronal patterns in the brain.
Biologist Richard Dawkins first introduced the idea of memes,
units of belief that is firmly entrenched in human brain and
is capable of being propagated laterally among the society of
brains. On page 323 of his book The Selfish Gene, Dawkins
mentions that meme is a neuronal wiring up as confirmed by
brain scientist Juan Delius of University of Konstanz, Germany.
Much has been learned and studied since then on the cerebral
basis of religious memes.
Dr. James Austen in his monumental tome of 844 pages : "Zen and
the Brain" states on page 18 "The sense of great Self (Mystical
Experience) must come from the brain, since it is the organ of
the mind. Dr. Austen is a neurophysiologist who has also practiced
Zen meditation!
Some quotes from "The Mystical Mind : Probing the Biology of
Religious Experience" by Eugene G. D'Aquili and Andrew B. Newberg:
p22-24: Says brain is the source of all religions/mystical
feelings/experiences. Cites brain imaging studies as the proof.
p-79: Myth making is seen as a behaviour arisining from the
evolution and integration of certain parts of the brain.
p-142: Temporal Lobe simulation is behind seeing light at the end
of a tunnel in nera death experiences(NDE). Also mentions that
hippocampus in the brain is responsible for seeing near relatives
and a panoramic view of life in such experiences.
p-155:
"As long as human beings are aware of the contingency of their
existence in the face of what appears to be a capricious
universe they must construct myths to orient theselves within
that universe. Thus they construct Gods, demons, spirits and
other personalized power sources with whom they can deal
contractually in order to gain control over a capricious
environment... Since it is unlikely that humankind will ever
know the first cause of every strip of reality observed it is
highly probable that it will always generate Gods, powers,
demons and other entities at first causes to explain what it
observes. Indeed people cannot do otherwise."
Some references:
1. Newsweek May 7, 2001 (God and the Brain)
Two prisoners, A and B, are being held in separate cells with
no means of communication. The prosecutor offers each of them
a deal. He also disclosed to each that the deal was also made
to the other. The deal he offered is this:
a) If one guy confesses that both of them committed the
crime and the other guy denies it, then he will go free
and the other guy will be sentenced to 5 years.
b) If you both deny the crime, then both will be
sentenced to 2 years.
c) If both confess to the crime, then both will be sentenced
to 4 years.
If someone confesses then he either goes free (0 years) or
gets 4 years. If he doesn't confess then he gets either 2
years (if both denies) or 5 years (If the other guy confesses)
. So from each one's individual perspective the payoff is
better if he confesses rather than denies (0 or 4 years is
better than 2 or 5 years). So if both are logical and selfish
they both should confess. The result is that both will fare
worse than if they had BOTH denied, contradicting their
individual logic! So if such prisoner's dilemma is repeated
many times and if the two prisoners can communicate then even
though they may initially both confess, by trial and error they
will learn to cooperate instinctively and will evolve an ethical
code "thou shalt not confess". Thats why criminal gang members
do not tell on each other, Evolution works that way. Over
millions of years, evolution has instilled an ethical sense
starting from the tribal group of early people to the modern
people. The sense of morality is not implanted in human mind
from some transcendental realm, it is a hardwired instinct.
Our "feeling" of conscience is an emergent property of the
brain reflecting that hardwired instinct. And ethics is not a
unique trait of human species. A primitive form of code of
ethics is seen among wolf pack as well, where pecking order,
punishment and rewards are observed. Of course, human brain
having possesed the emergent property of self-consciousness
has the most advanced and complex form of code of ethics.
Evolutionary biologists use the term adaptive for those
instincts that favor the survival and propgation of genes, and
those that hinder anti-adaptive. Moral instincts are the
adaptive traits of evolution and are favoured overwhelmingly
over anti-adaptive traits. Evolutionary psychology not only
explains the origin of moral instincts but also the origin of
the "immoral" (can be neutral or anti-adaptive in the
evolutionary sense) instincts as well. In Bible we see Jobs
imploring God to explain why he is subject to so much evil and
injustice? God did not provide any satisfactory answer. But now
Evolutionary biology is offering a plausible explanation. In
fact so much of evidence and insight has been gained in recent'
times that a plethora of scholarly scientific books and articles
have been written on the evolutionary origin of vice and virtue,
on evolutionary ethics. So why do we have evil? If morality is
selected by natural selection then why do humans have immoral
instincts as well? It is best understood by analogy. One
cardinal point is that evolutionary force, like humans are lazy,
they try to achieve its goal (survival, propagation of genes) by
the easiest/ simplest possible way. Let us take an analogy. Let
us say the US militray wants to kill the insurgents in an area.
To kill only the insurgents it requires a lot of work to gather
the information about the location and also a lot of planning
and discipline to selectively target the bombing. It is much
easier to bomb an extended area killing the maximum number of
civilians, that is guaranteed to kill the intended insurgents
but at the price of killing a large number of innocent civilians,
as an overkill/collateral damage. Another nice analogy is
provided by Gould and Lewtonin by the spandrel in arches. A
spandrel is the roughly triangular region on either side of the
top of an arch, a necessary but unintended byproduct of
architectural design. An arch cannot be built without the
spandrel. Immorality is the collateral damage of evolutionary
strategies, so to speak. Evil is a necessary but unintended
consequence of evolution.
Among the collateral damage an important unintended instinct is
rape. The reason the practice of rape still survives is that it
is not anti-adaptive. The forces of evolution does not have a
moral sense like we do. It does anything to help maximize gene
propagation. And rape does not disfavour that. Not only that it
may have served as one means of propgation in past. That is the
theme of the book "The Natural History of Rape" by evolutionary
biologist Thornbull and anthropologist Palmer. Their central
argument is that "rape is a genetically developed strategy
sustained over generations of human life because it is a kind
of sexual selection--a successful reproductive strategy"
Thornbull and Palmer has been predictably misunderstood as
condoning rape. They are not. It would be a naturalistic
fallacy to promote a "IS" into an "OUGHT". They were simply
explaining the evolutionary origin of rape. But they were not
justifying or condoning it. Description is not prescription.
Explanation is not exculpation. Matt Ridley, another biologist
also says "Rape was evolutionarily adaptive" in his book
"The Origins of Virtue." as quoted in p-45 of "Sexing the Brain"
by neuropsychologist Lesley Rogers.
The presence of evil is an inevitable result of the physical
laws acting to sustain equilibrium or stability and thus avoid
extinction of a species. As I mentioned earlier evil is a
necessary unintended byproduct of evolution. Lying can be seen
to be another such necessary but unintended trait. As physicist
Heinz Pagels nicely illustrates in his book "The Dreams of
Reason", page 330:
In various debates and discussions, when taking a principled
position on an issue, sometimes the secular humanists and
freethinkers aver their disbelief in God, soul and other
religious beliefs. But how accurate is this self-
characterization? This is not to doubt the sincerity of those
freethinkers, they truly believe they are atheists or agnostics
and dismiss the idea of soul. But some of the idealistic
positions and views adopted by many secular humanists (atheists
or agnostics) under careful scrutiny betray an underlying
subconscious assumption of a non-material existence of some
(divine/spiritual) entity or reality and a subconscious
reluctance to accept a pure materialistic view of reality.
Hopefully this will become clearer as I try to carefully
explain the rational basis of this conclusion/hypothesis.
Theists are seen to jump almost instinctively to the
conclusion that atheism leads to lack of morality, to a lack
of an absolute reason to utter a "Thou Shalt/Thou shalt
not..". In a sense they are correct, but not in the sense
they purport to convey through their apologetics. It is true
that without the possibility of the existence of a divine
or higher entity or the permanence of the self in whatever
sense, there remains no compelling basis for asserting a
"Should" in any matter of life. A strict belief in
materialism, or a lack in the belief in spirituality, where
no higher reality is allowed, necessarily leads to an
existential state of meaninglessness from a pure rational
perspective, i.e there remains no basis of rationally
justifying a "Should" on any matter or to find a meaningful
purpose of life itself, ultimately leading to nihilism.
After all, if our life is transient, purely material, and
nothing remains after our death, why SHOULD the "SHOULDS"
really matter to us at all? Obviously the "SHOULD" must have
to be based on some underlying moral axioms. Take away the
axioms, and the "Thou Shall/Shall not.." falls apart. Axiology
as a branch of philosophy loses its raison d' etre. How and
why do these moral axiom emerge? What is the basis of the field
of axiology in ethics? Lets look at it carefully. Take the
case of any principled position of a human rights activist
on a social or political issue. We can try to analyze the
basis of this principle by a series of "why" and "because".
We can start by asking why should we believe in principle
"A"? Immediately the why-A would be explained by "because-B".
Then we can ask why B? A would also be
explained by a because-C. Ultimately we will arrive at
"because-Z", which cannot be explained away reductively any
further without becoming circular. Z has to be
accepted as an axiom. For some "whys", the moral axioms at
the end of the why chain can be justified only from an
evolutionary consideration, to prevent extinction of human
species. Although some individual may even question, why
should it matter to him if humanity becomes extinct after
his death, if lives a fulfilled and happy life? Well, it
may not matter to him, but it matters to evolution (Laws of
Physics), thats why evolution hardwires that instinct (The
instinct to preserve human race) in MOST humans. But for
many other moral axioms such evolutionary justification
does not exist. Even with those moral axioms whose
existence are rooted in the evolutionary imperative of
preventing extinction, modern biotechnological innovation
having almost eliminated the threat of extinction(barring
a catastrophic act like global nuclear conflagration),
nevertheless makes that explanation no longer justifiable
from an evolutionary consideration anymore. We cannot for
example by pure reason alone justify why we should help the
freedom fighters of a nation struggling against its occupying
forces, or help and petition for the release of a prisoner or
victim of religious or political persecution etc. We accept
all these as moral axioms originally rooted in evolutionary
instincts. These axioms form the primitives on which axiology
of ethics is founded. Even a strict atheist and materialist,
who may have no rational basis for morality or virtues as
claimed by theists, still feel a strong intuitive sense of
moral and ethical values, thanks to evolutionary hardwiring.
They cannot force themself to commit a crime, even though
they are convinced that there is no judgement day hereafter,
or even if they are granted immunity here on earth.
Evolutionary instincts are powerful enough to deter many
atheists from committing acts that are generally agreed to
as immoral. Those instincts are also present in many
theists, and for them the external religious imperatives
merely reinforce their instinctive moral sense, the moral
sense is not created anew by religion, nor does religion
add anything extra either. But the fact still remains that
there is no rational basis of believing or adhering to a
moral principle. No apriori "reason" in the true sense can
be put forward to explain why an axiom should be accepted
We may instinctively find the axiom appealing and natural.
But that intuitive appeal is due to evolutionary effect, not
due to any non-material independent entity outside of the
brain speaking to "us" in the heart. The "I", the "us" are
just an illusionary perception of an entity beyond the brain.
The brain is all there is to it, if one does not believe in
an invisible soul independently affecting the brain and
controlling the thoughts. Thoughts are one-to-one mappings
of a complex series of neuronal activities in the brain in
interaction with the environemnt using feedback mechanism
of the brain's memory. The moral axioms are really a product
of evolution. Evolution instills those values and emotions
that maximize the odds of survival and propagation of a
species. We can, if we wish, say that moral axioms are
created by the activities in the pre-frontal cortex of
human brain, often called the executive brain ("The
Executive Brain" - Goldberg) But what created the
pre-frontal cortex? Evolution. All human values and emotions
(in other words human mind, with all its facets) are
evolutionary products(via the brain). Aesthetic sense,
passion for love, the universal appeal of the smile of a
child, all these seem so "heavenly", it is hard to accept
them as purely rooted in material basis through the blind
unconscious workings of the laws of nature(Physics). These
are all "Grand Illusions" in the words of evolutionary
biologist Victor Johnston (Why we feel: The Science of
Emotions). The sense of beauty in homo sapiens is known to
have evolutionary root as well dating back to the time our
hominid ancestors roamed the African Savanas (The Artful
Universe - John Barrow). When we enjoy the music of
Beethoven's Fifth Symphony, the haunting cameo performance
Harpo playing harp in the otherwise hilarious Marx brother
comedy, the surrealistic painting of Dali or Magritte, the
velvet sound of George Shearing Quintet, the complex far
out sound of Stan Kenton's progressive jazz orchestra
performing Bob Graettinger's "City of Glass" suite in the
50's, the haunting Bangla poem "Kajla Didi" by Jotindro
Bagchi, or Tagore's "Sonar Tori", all seem too ethereal,
too "other worldly", too meaningful to be accepted as
merely resulting from the blind laws governing matter and
energy. But are the laws of Physics really blind, inanimate?
Human brain, which is the ultimate seat and provenance of
these beautiful ethereal products, is itself the product of
the Laws of Physics. The laws of Physics has these ethereal
qualities latent in it. The Laws of Physics is very much
alive, conscious. It is the engine driving evolution. It
took millions of years for evolution to craft these
beautiful products guided at each step by the laws of
physics, and shaped by the contingencies that inevitably
accompany a large complex environemnt. Thus even
rationalism, which I value so much, is also a creation of
evolution. Of course not all human brains are built to be
equal in rational, moral or other senses by evolution.
Gene and environment determine the degree of these senses
in each individual. Thats why Henri Bergson was an
intuitionist, whereas David Hume was a strict empiricist.
Its just that rationalism as an element of human thought
arose out of evolutionary mechanism of the brain over time.
But the point is that it is the brain that is the seat of
and source of all elements of human thoughts and emotions.
In is fascinating book "Sex and the Origin of Death",
microbiologist William Clark invites us to a thought
experiment, where a renowned brain surgeon suffers from a
serious brain diseaas which only he is competent enough to
cure through brain surgery. With the help of his able
assitants and careful rehearsals, he successfully operates
on his own brain and cures himself. He draws wide accolade
from colleagues and general public. Then Clark asks us to
ponder the question, who deserves the kudos, who truly
accomplished the remarkable medical feat? It is the brain
of the brain surgeon! The evolutionary urge to save itself
from dying, the brain caused the hands of the brain surgeon
to perform the meticulous and delicate operation to save
itself, and also convinced other brains (assistants') to
lend a "hand" in this most complex act of self-preservation.
The "I" or "we" refered to in common parlance is nothing
but "our" brain in action (Like a process is a running
program), with all its synaptic connections (The Synaptic
Self - Joseph Ledoux) and the relative concentration of
neurotransmitters. There is no "I" outside the material
substrate of the brain. Many secular liberals, who may even
claim to be atheist may find this insight disturbing and
unpleasing, and thus would argue, that "we" are not just
pre-frontal cortex, "we" are more than just a material
brain, "we" are HUMANS. As humans, "we" are endowed with a
noble human spirit. How often we hear even from even non-
religious people that morality cannot be derived by science
or knowledge, but from metaphysics or philosophy. Any
suggestion of using scientific approach in social issues is
dismissed by them as scientism. As if science is man made,
created in the brain but philsophy or metaphysics is not
man made in the brain, but derived from some sublime from
outside the brain, from some divine, transendent world.
This is where they betray their subconscouss assumption
of an entity beyond the material substrates of humans,
essentially referring to a "soul". The moment one conceives
of some non-material entity independent of the brain,
responsible for "our" thoughts and emotions, morality,
freewill, altruism, patriotism, etc, they are essentially
referring in a cryptic way to soul, or some non-material
external entity, endowed with "freewill", influencing our
thoughts and actions, and breathing life inot our body.
We can call them cryptovitalists/cryptodualists. They are
essentially rephrasing the old Cartesian dualism, of a
spiritual mind external to the body or brain.
This crypto-vitalism/dualism also explains why so many who
otherwise claim to be freethinking liberal atheists are
uneasy accepting the cold fact that life is a result of the
natural laws of physics at work. Accepting that goes
against their grain and their subsconscious assumption or
hope of a divine/sublime entity beyond the material
substrate of the human body. The same explains why many of
them also feel uneasy accepting the idea that Biology is
causally linked to Physics. A belief that biology is not
linked to physics provides a subconscious hope that there
may be some divine/non-material force or entity guiding
the laws of biology, because Physics being a science of
matter and energy, seems to lacks such divine, living driving
force. There is no other reason for insisting on the lack of
a causal link between Physics and biology, when it is self-
evident to all leading scientists and to science literates
that there is such a hierarchical link. These crypto-vitalists
miss one obvious point, the point that there is no
fundamental difference between living and non-living matter,
the difference is due to the complexity and emergent
effects. Non-living matter (including a corpse) are in
thermodynamic equlibrium, living matters are in highly non-
equlibrium thermodynamic state. Laws of Physics do control
the behaviour of all matter, living, or non-living. All
the vital prcesses of a living organism, viz. metabolism,
reproduction etc, involve any mechanism that violates or
does not follow any known laws of Physics, like the law
of conservation of energy, law of entropy etc. The
cryptovitalists need not delink biology from physics for
a hope of a spiritual driver for biology. The driver of
Physics itself being unknown (The ultimate "?" which I
mentioned in my earlier posts), they might as well pin
their hope on a spiritual driver for the laws of physics.
To me, it seems more sensible to seek spirituality in
Physics. Here I am using spirituality to denote the
possibility of an higher inteliigent transendent reality
manifesting itself through the intermediary of the
creative works of the laws of Physics in action.
If the laws of Physics and the emergent laws of
complexity can conspire through evolution to craft the
most complex and amazing object in the universe called the
human brain, which can conceive of and seek spirituality,
moraluty and all that we consider divine, then the laws of
Physics may very well contain the seed of spirituality and
morality. If brain is a creation of the laws of Physics, and
if the created(human brain) can discover its creator (Laws
of Physics) in an intriguing concsiousness loop, as physicist
Paul Davies points out (The Mind of God), then may be
someday, the brain will also discover the reason why, not
just how, the Laws of Physics created the brain with all
its beautiful, reation of arts, morality and spritiuality.
And then we humans can feel a sense of purpose and a reason
to find meaning and permanence of life. Humans may then
even integrate morality with the laws of nature(Physics),
fulfilling the ultimate dream of Auguste Comte, the founder
of sociology and tyhe positivist philosopher who envisaged
a a social science based on natural science, a dream re-
expressed in what evolutionary biologist E.O. Wilson calls
"consilience", the grand synthesis of the social and the
natural sciences. Maybe someday, when the holy grail of
Physics (Theory of Everything, the final Superstring Theory,
..) is found, the reason for our existence may also be
found embedded in that final theory. Then we will not
suffer from the "grand illusion". Of course the ultimate
mystery of existence, i.e why the universe at large exists,
or why the laws of Physics exist at all, will always remain
a mystery, providing a permanent source of pabulum for the
pref-frontal cortex. So that ultimate "?" will always provide
a room and excuse for being spiritually hungry (we all are to
varying extent) for a POSSIBLE higher reality. We will never
be able to logically refute a creationist who may believe
that its not life that is created by God, but the laws of
Physics is, and that evolution (biology) is a consequence
of the laws of Physics created by God, leading to the creation
of life(biogenesis).
This essay is an attempt on my part to create a conscious
awareness among readers about the intimate connection between art
and science, a fact that I deeply appreciate and which is often
ignored or unappreciated by even some highly qualified
intellectuals. I am not a scientist, there is no pretense of any
original scientific idea being proposed, but merely an attempt as
a science writer (however amateurish) to cull and present the
wealth of literature that exists which confirm and explain the
nature of this connection between the art and science. In this
essay I would like to touch three different aspects of the art-
science connection. Firstly the correlation of art and science,
i.e. what objective scientific factor maps to specific subjective
perceptions in art and beauty, secondly the brain's role in artistic
perception, and thirdly the evolutionary origin of the sense of
art and beauty.
It has been a cliche to say that beauty (or art in general) defies
definition, it is said to be in the eye of the beholder. Art or
beauty, like consciousness, is to be perceived, not understood.
But that cliche is now a bit outdated. There is nothing taboo in
science. Definition, a universal one, of art may not exist. But to
insist that art and beauty (more specifically the sense of art
and beauty) is to be perceived, not understood (or that it can't
be understood) does not wash anymore in view of the modern insights
of science, the science of evolution to be precise. Definition is
not that fundamental or profound in understanding something we
universally agree exists, like beauty and consciousness. More
fundamental is to understand the scientific basis of the origin
of the existence of those things we agree do exist. Evolutionary
biology (or Evolutionary psycholoy to be precise) does offer a
fundamental explanation of the emergence of a universal artistic
sense in human species.
Also historically a stereotypical attitude existed among poets
and literateurs about a supposed contradiction between artistic
sense and science. Here I mean science in a general sense to include
mathematics and logic as well. English poet John Keats quite
paradoxically, accused Newton of ruining the beauty of rainbow by
explaining it with the laws of optics, while famously stating that
"truth is beauty" in another context. Other poets have also made
oblique references to science and logic in their poems, like
Eugene Cummings, Emily Dickinson (e.g "A color stands abroad, on
solitary fields, that science cannot overtake but human nature
feels.."), Wordsworth and many others. Another historical figure
who contributed to this anti-science myth was Jean-Jacques
Rousseau who seemed to have an almost utter disdain for science.
C.P Snow in his classic book "The Two Cultures and the Scientific
Revolution" pointed out the general disdainful (or at best
apathetic) attitude of intellectuals in the arts hold toward
science, and their refusal to recognize scientists as intellectuals!.
It is worthwhile to mention the story of Nobel Physicist Feynman
(in the book "No Ordinary Genius" by Christofer Sykes) who was
once told by his artist friend holding up a flower: "I as an
artist, see how beautiful the flower is. But you as a scientist,
take it apart, and it becomes dull". To which Feynman responded
that he sees the same beauty that the artist does, but he in
addition sees the inner beauty of the flower as well, seeing how
the tiny cells make up its petals, how the beautiful color of the
flower arose out of an evolutionary adaptation to attract the
insects to pollinate, all of which the artist friend missed.
Another poet, Walt Whitman said in his poem "When I Heard the
Learn'd Astronomer", how he listened to an astronomy lecture and
got tired and bored, walked out of the room, into the mystical
moist night so he could look up in perfect silence at the stars.
An apt yet respectful response to Whitman's poem was given by
Victor Weisskopf in his foreward to the book "Atoms of Silence"
by distinguished astronomer Hubert Reeves saying "Hubert Reeves
knows what the astronomer said; but he also is out there and
looks up with Walt Whitman in silence at the stars" (p-x, "Atoms
of Silence"). Feynman commenting on the poem by Whitman in a
similar way in his famous Feynman Lectures on Physics, said that
he too looked at the stars on a deserted night and felt the awe
and wonder, but his awe and wonder was enhanced much more to
realize that light from the star took millions of years to reach
his eyes, that the stuff out of which his body is made was once
belched out of by a supernova star. It does no harm to the
mystery to know a little more about it, for far more marvelous is
the truth than any artists of the past imagined! Famous science
writer Isaac Asimov writing on "Science and beauty" in the book
"The Roving Mind" commented on Whitman's poem this way: "Of course
the night sky is beautiful, but is there not a deeper, added
beauty provided by astronomer?", and then goes on to describe in
lyrical paragraphs the awe inspiring wonders of the stars,
galaxies and the universe.
It is sad that so many celebrated literaries in history have
made such hollow and caustic remarks pitting science against
arts and accused the pursuit of scientific truth of ruining
the beauty. We marvel at the beauty of the mighty Ganges river.
Does it diminish our sense of beauty once we reach Gangotri,
the cowhead, the source of the mighty Ganges in the Himalyan
ranges? Not so. Those who have seen it can vouch for the awe and
mystical feelings (both are essential to artistic sensitivity).
that it generates. Seeking for the scientific truth is similar
to seeking the Gangotri. Science seeks the Gangotri of
other beauties in nature, rainbow was one such example. Science
rather deepens the sense of beauty that is already within us.
Because every discovey of the truth pushes the mystery one more
level further. The ultimate mystery still remains and inspires
scientsts to go even further, in a constant pursuit of the
Gangotri of the Gangotri and so on, keeping alive an eternal
inspiration and urge for creativity, the two quintessesnce of
artistic creativity.
Famous British astronomer Sir James Jeans writing on "Science and
Mysticism" in his "The Nature of the Physical World", quotes from
a page on winds and waves in a textbook of hydrodynamics, and
then compares it with the aesthetic experience of actually
watching the sea waves dancing in the sunshine. The remarkable
symmetry in nature which inspired Einstein in his discovery of
the profound laws of relativity and gravitation was to him a
thing of utmost beauty. But Einstein also enjoyed the beauty of
music, in addition to the beauty of nature. He used to play
violin. It is relevant here to mention a quote by Einstein:
"Pure mathematics is, in its way, the poetry of logical ideas.",
which appeared on May 1, 1935 issue of New York Times.
Nobel Laureate Physicist Dirac also emphasized the need to
appreciate beauty in Physics and credits a sense of beauty for
his remarkable insight into arriving his famous Dirac's equation
for which he received the Nobel Prize. He claimed that a "keen
sense of beauty" enabled him to discover the wave function for
the electron in 1928. As Dirac famously remarked reminiscing that
discovery in the May 1963 issue of Scientific American magazine:
What can be more apt than a book resulting from the collaboration
of a professor of Englsih and a professor of Phyics to drive
home the intimate harmony between science and arts? An example of
such a book is by Thomas Vargish and Delo E. Mook, in their book
"Inside Modernism: Relativity Theory, Cubism, Narrative", where
they write:
G.N. Watson, one of the most distinguished mathematicians of the
early twentieth century said that some of Ramanujan's
mathematical formulas gave him the same thrill as Michelangelo's
"Day," "Night," "Evening" and "Dawn" in the Medici chapel in the
San Lorenzo in Florence. (From p-545 of Roger Penrose, The
Emperor's New Mind: Concerning Computers, Minds, and the Laws of
Physics, Oxford UP, 1989)
Quantum physicist and philosopher David Bohm (Who recently passed
away) in his paper "On the Relationships of Science and Art" in
the book "Data: Directions in Art, Theory and Aesthetics",
Anthony Hill (ed..1968, London), also emphasizes the unity of art
and science by tracing the parallelism between the artistic
evolution beginning with Monet and Cézanne and going on to the
Cubists and to Mondrian and the development away from
representation and symbolism and toward what may be called 'pure
structure' that took place in mathematics and in science.
As I mentioned earlier art cannot be defined in a simple word.
The existence of art is agreed to by its effect on human mind. If
art is identified by the joy and pleasure that it creates in the
mind and the creativity that goes into its creation, then quite
easily science is an art form and scientists the artists of this
art form. Just as music, painting, poetry are distinct art form,
so is science. It is as baselss to say that science(or scientists)
cannot appreciate arts as it is to say a musician canot
appreciate poetry. A superstring theorist engages in the string
research with an immense sense of appreiation and sensitivity for
beauty. String theory is as elegant if not more as any
sophisticated work of art. The fact of artistic element in
scientific truth is also true for any fundamental science
including molecular biology. It is no wonder that Molecular
Biology professor Bonnie Bassler says in the 17 July 2003, issue
of Nature magazine in response to the question "What' s the one
thing about science that you wish the public understood better?" :
Alert readers should realize that all such theories of aesthetics
are attempts to correlate or map subjective beauty with some
objective measures. They do not explain why beauty is perceived/
felt in human minds in those objects of beauty possesing those
objective characteristics,i.e the normative aspect of art
appreciation, the "hedonic tone", as Evolutionary Psychologist
Victor Johnston calls it. For that we have to turn to
evolutionary psychology.
Now Unless one believes in soul (despite there being no clear
objective definition or evidence for it's existence), one cannot
avoid confronting the indisputable fact that humans (which
include their brains) are the products of evolution. Evolution,
itself being an emergent effect of the underlying fundmanetal
laws of nature (Physics to be precise), all human traits and
pursuits like art and music and human affinity for them are
ultimately traceable to the laws of physics itself. But we don't
need (nor is it practicable) to go to the deep level of physics
for understanding every human trait. The language of
evolutionary science suffices for such an understanding. Just as
we can understand what a piece of software does simply by
examining its high level code (visual basic, C etc), without
having to analyze its underlying assmebly or machine code),
similarly we can understand human traits in the language of the
laws of evolution (natural selection, mutation, genetic drift,
adaptation, exaptation etc).
The new science of evolutionary psychology has already made great
strides in understanding a broad range of human emotions and
traits (morality, sexuality..). Since beauty, arts, morality and
virtually all human traits and pursuits are created "in" human
mind(brain), so if humans (i.e all the organs) are the products
of evolution, so are these traits. They cannot be supernaturally
implanted in human mind from some transcendental world (As a
proponent of divine origin of human existence would suggest). We
can call "love", "beauty of a flower, child, a woman.." all as
divine, sublime, ethereal, but these are mere words to express
human emotional affinity for arts. At the bottom lurks the stark
truth that nothing is too divine or sublime to transcend the laws
of physics. There is no evidence for such transcendence. There is
ample evidence to offer a plausible explanation of the emergence
of not just life but also the emergence of consciousness and
human traits and emotions. Of course the laws of physics can be
viewed (As Einstein did) as divine (After all, the laws of physics
are not created by human,its the other way around),if one has to
invoke divinity at all, as an ornament of expression.
One particular aspect of human emotion is the urge to appreciate
and attribute beauty to objects (material and non-material)
Beauty is perceived in real objects like flower, gems, or in non-
material objects like poetry, songs. But whatever the object of
the appreciation of beauty, the common aspect of those objects
are they all carry certain information,patterns or arrangement
that convey meanings to human mind, the end result being that
they arouse the pleasure centers of human brain. So the deeper
question is why or how did this mapping (or cause-effect
relationship) between certain information or pattern and the
pleasure center of the brain arise in humans. As I argued earlier
it must be rooted in the evolutionary mechanism. All human traits
are either direct adaptation to the evolutionary selection
pressure, or are the byproducts or side-effects of such adaptive
strategies for survival, the so called spandrel effect. Spandrel
is the term used for the spaces between the pillars of an arch
that is not an intended part of the arch design but is
nevertheless an unavoidable consequence of the arch design.
Spandrel is a special case of exaptation, where a feature
originally selected was reselected to adapt to a differenet
selection pressure. Spandrels are adaptations with no real
survival values. Artistic sense is viewed by most evolutionary
psychologists as spandrels of evolution.
Incidentally I must remind the readers that survival in
evolutionary terms means propagating the genetic code to
offsrpings, it does not refer to the physical survival of a
human (If a human dies after propagating his/her gene, then
evolutionarily that person has survived). A human body is a
temporary repository to store the genetic code which has been
propagating generations after generations over millenia.
That aesthetics has biological root was suggested quite sometime
ago by even a non-scientfic literary Frederick Turner in his book
"Natural Classicism", where he expressed his view of aesthetics
as expressions of primordial biological preferences. But the
decisive book based on hard science of evolution that inspired
many evolutionary psychologists was the 1992 book : "The Adapted
Mind: Evolutionary Psychology and the Generation of Culture" a
collection of essays by many researchers, edited by evolutionary
psychlogists Jerome H. Barkow, Leda Cosmides, and John Tooby.
Several books and articles have appeared since then further
giving a firm foundation to this new paradigm of the origin of
art. A widely acclaimed book is Nancy Eiken's "An Evolutionary
Perspective on the Nature of Art" which is inspired by an earlier
book by E. Dissanayake, "Homo aestheticus: Where art comes from
and why". Readers can rad this book online at:
In the book Biopoetics: Evolutionary Explorations in the Arts,
(1999), edited by Brett Cooke and Frederick Turner the editor
remarked that “The evidence is steadily mounting,” and further
remarked in the their introduction, “that if we wish to
understand our profound and long-standing impulse to create and
enjoy art we are well advised to attend to our evolutionary
heritage. . . . Even if art is for art’s sake, it follows that we
seriously consider what that purpose means in Darwinian terms.
A very well-written scholarly article on the evolutionary
adaptive origin of art is: "Is Art an Adaptation? Prospects for
an Evolutionary Perspective on Beauty" by Univ. of Torornto
Philospher Ronald de Sousa published in The Journal of Aesthetics
and Art Criticism, Volume 62 Issue 2 Page 109 - June 2004.
Readers can read the article on line at Sousa's site at:
http://www.chass.utoronto.ca/%7Esousa/artfunction/art.htm
In his book "Evolution and Literary Theory", author Joseph Carrol
not only argues for a Darwinian explanation of art(Literature in
partiular), but also debunks the poststructuralist (Postmodernist)
dogma of textualism of leading exponents, Derrida, Foucault and
their many disciples who claim that the pursuit of objective
insight into anything is an impossible endevour.
Interested readers can check Carroll's website at:
http://www.umsl.edu/~engjcarr
British astronomer and prolific author John Barrow also has
discussed the evolutionary origins of aesthetic sense in chapters
23 and 24 (Aptly titled "Aesthetics") of his book: "Between
Inner Space and Outer Space". The primitive sense of beauty among
our early hominid ancestors emerged due to its adaptive value. In
a hostile terrain, constantly exposed to predatory threats, the
adaptive trait was to appreciate terrains and land shapes that
favoured survival. That may explain whay landscape art became
particularly attractive to humans. Also plain landscape was
favourable to survival, as it was easier to spot predators. So
liking a plain landscape would be evolutionarily more adaptive.
In other words there is a utilitarian basis (evolutionarily
speaking) for artistic likings. That is artistic likings are
created innhuman minds by natural factors. Not every individual
human being may be consciously aware of this fact of nature in
everyday life. There is no reason to be. Humans are ultimately
programmed machines, with a remarkable property that *some* (due
to spandrel effect) humans are consciously aware of the fact that
they are programmed machines, most are either unaware of this or
refuse to accept it as fact. Over time that utilitarian basis of
artistic sense may have ceased to exist but the evolutionary
instincts of attraction for art and beauty lingered on like a
vestigial organ and took on its own indepenededt existence as more
sophisticated art appreciation. Also it must be emphasized that
we cannot trace every shade or nuance of art (e.g surrealism)
directly to specific evolutionary adaptation. As the analogy of
spandrel illustrates there can very well be unintended (but
inevitable) byproducts of evolutionary strategies due to its very
trial and error nature. Artistic sense as a general instinct is
what evolution prescribes in humans. By products of that general
prescription through individual variations (due to mutation or
non-deterministic environmental effect) may arise which may not
be directly adaptive in evolutionary terms and which may be quite
sophisticated. All these show how simple sense of beauty might
have evolved. But we know the complex are built from the simple
by repetition. Barrow also discusses how affinity for certain
shapes and colors could have been evolutionarily more adaptive to
our primitive ancestors leading to the appreciation for flowers,
paintings and other shapes,colors patterns etc. He also mentions
an indirect evidence that musical sense also is rooted in
evolution by citing the the 1975 discovery of two physicists,
Richard Voss and John Clarke, at the University of California,
Berkeley that many classical and modern musical compositions
which are liked by most are closely approximated by what they
call 1/f type spectral noise over a very wide range of
frequencies. It is the universality of such characteristics in
the music of all cultures that point to the common evolutionary
basis of such liking in our evolutionary past. It would be highly
coincidental that all cultures developed a similar musical sense
if it was not due to evolution. Also the fact that human brain is
attuned to certain musical sounds, as modern neurological studies
of the interaction between brain and music has revealed (See the
November '04 issue of scientific American for a recent article on
Music and the Brain by Norman Weinberger), strongly suggests an
evolutionary root of musical sense, since brain, like any other
organ is also a product of evolution. The fact that even fetuses
within the womb respond to music discriminatively (as cited in
the SciAm article refered to earlier as well as on p-37 of the
book "The Science of Music" by Robin Maconie (1997) lends
additional evidence favouring the genetic (thus evolutionary)
basis of musical sense.
Another research into the connection between brain and arts that
should be mentioned is that by neuroscientist Ramachandran
(Author of the best seller "Phantoms in the Brain") of the Center
For Brain and Cognition, University of California, San Diego. In
the paper titled "The science of art" in the Journal of
consciousness Studies, 6/7, 15-41, Ramachandran & Hirstein detail
their views based on neurological research on various aspects of
art perception viz,(a) The logic of art: whether there are
universal rules or principles; (b) The evolutionary rationale:
why did these rules evolve and why do they have the form that
they do; (c) What is the brain circuitry involved? They arrive at
what they call "Eight laws of aesthetic experience" analogous to
the Buddha’s eightfold path to wisdom.
An important sense of beauty among humans is the appreciation for
beauty of the opposite sex. This is very well understood in
evolutionary terms and extensive literature exists reflecting the
findings and views of many evolutionary psychologists on the
insight into the evolutionary basis of sense of beauty of other
humans (of opposite sex), which we will refer to as sexual beauty.
To put it in one line, the findings of Evol. Psychology is that
sexual beauty is an indicator of good health and genetic fitness,
which is what evolution cares all about. The traits that men
consider beatiful in women are those that indicate female genetic
fitness (like fertility). A leading pioneer is Devendra Singh of
Univ. of Texas at Austin. He has identified waist to hip ratio of
women as one such fitness indicator. When a male identifies a
woman as pretty he may not be consciously aware of the waist to
hip ratio, it is just instinctively wired by evolution.
Evolutionary biologists like David Buss, Desmond Morris, Robin
Baker and many others have identified many such markers of beauty.
Among males one such fitnes marker is facial symmetry which women
instinctively perceive as male beauty. Those who have seen the
documentaries on sex on discovery/TLC (Like the multipart series
of the Huamn sexes, the Science of Sex, The Sex Files etc) and some
other TV channels must be familiar with some more of these aesthetic
fitness markers.
The fact that artistic sense or aesthetic sense is rooted in
sexual selection of the brain has been the recurring theme of
English biologist and science writer Matt Ridley, in his verbose
book "The Red Queen".
More recently in the paper titled "Aesthetic fitness: How sexual
selection shaped artistic virtuosity as a fitness indicator and
aesthetic preferences as mate choice criteria" by psychologist
Geoffrey Miller in the Bulletin of Psychology and the Arts
2(1), 20-25 (Special issue on Evolution, creativity, and
aesthetics) reiterate the biological basis of aesthetics and the
sexual selection factor in particular. Readers can check the
following URL for an online version of the article:

Let me conclude this overview by listng some more relevant books
on this specific topic:
A lot of the debate on evolution is focused on whether evolution
has occurred or not. Defenders of evolution take great pains to
offer the evidence and logic in support of evolution and to refute
the position of creationists. But even many of the subscribers to
the notion of evolution do not grasp the full implications of the
fact of evolution. That will be my focus in this essay. The FACT of
evolution is beyond debate, the detailed mechanism is not. My essay
assumes the fact of evolution as a given. The simple fact of
evolution has profound implications that can have a tremendous
impact on the way one looks at life and it's various aspects
including morality, values, social customs and human behaviour in
general. When I refer to evolution, it will mean all the detailed
insights obtained through the research in the fields of
evolutionary biology/psychology.
The lesson of evolution is that all life forms including humans
arose out of an incremental evolution from a primitive life form
over billions of years by a purely natural process and that the
primitive life form itself arose out of an incremental evolution
of complex molecules in the prebiotic atmospheres of early earth
through purely chemical processes, called chemical evolution. Since
the laws of physics is the ultimate governing principle behind all
natural processes, the conclusion we can draw is that evolution,
and thus all life forms are results of the laws of physics. One is
forced to conclude this by pure logic and evidence. Denying this
simple fact is tantamount to positing a "vital or divine" force
driving life forms, humans in particular. The temptation to deny
this fact is strong, specially because of the consciousness of
human mind, which is intriguing and difficult to explain precisely
by natural laws. Even many freethinkers who claim to believe in
evolution unwittingly deny this fact when they refer to "human
spirit", and passionately champion many of the "humanistic ideals",
saying that humans are not machines, that love, morality and "human
values" are not subject to mechanical laws etc. We have seen in
Mukto-Mona many freethinkers making the point that morality is not
subject to science or that science cannot be used to formulate
morality. While it is true that science cannot be used to formulate
morality, but it is also not true that anything else can be used to
formulate morality either. So that point cannot be used to
propose one's own favoured moral views to counter the moral
views putatively based on science that happen to contradict
their favoured views. But one thing that can be stated with
certainty is that the notion of morality, as a product of evolution,
is certainly a consequence of scientific laws (physics). So even
though humans cannot use science to formulate morality, morality
itslef is a product of scientific laws.
The cold, stark fact is that since all life forms are results of
pure natural processes dictated by the laws of physics, hence all
aspects of life, including consciousness, love, morality are necessary
(evolutionary)consequences of the same natural laws. This simple,
yet profound fact is hard to accept even by many secular humanists,
let alone theists. To say that any aspect of life is not subject to
the laws of physics is to say that that aspect is subject to an
(ill-defined) "divine force", "soul" etc. Pure and simple. There is
no in between. It is one of those either or cases. Any attempt to
have it both ways, just because it sounds politically correct or
appeals to one's taste will be intellectually disingenuous. Many
nontheists argue that biology (thus evolution) is not subject to
the laws of physics. That is a subtle manifestation of yet another
attempt to retain some semblance of a divine factor (by implication,
by denying the naturalness of biology). This position is taken by
philosopher Nancy Cartwright. In the book :
"The Large, the Small and the Human Mind" (based on a series of three lectures in
Cambridge's Tanner Series on Human Values), she challenges the
assertion by Stephen Hawking that chemistry is a consequence of
physics, and biology is a consequence of chemistry and thus human
mind is a consequence of the laws of physics. Of course
professional biologist/chemists (Richard Dawkins, Peter Medawar and
Peter Atkins for example) do not have this illusion and are fully
aware of this epistemological chain from physics to biology. Suffice
it to say that this epistemological chain from physics to biology
should be fairly obvious to anyone with a moderate understanding
of physics and biology and capable of critical thinking. One simple
observation can help: Most chemistry books devote their first few
chapters on the physics of atoms and molecules, and most biology
books devote their first few chapters on organic chemistry
The skeptical view questioning this epistemological chain is only
expressed by non-scientists. Coincidence? Not at all. Let me belabor
this point a bit more and cite some quotes from scientists on this
physics-->biology chain. While it is true that any view cannot be
justified by solely resorting to an argument from authority,
nevertheless this citation helps to reinforce this assertion of the
epistemological chain, because there is no similar example of
scientists expressing a view contradicting this.
Now let me cite some quotes of various scientists in support of
the above epistemological chain. Nobel Laureate Watson of
DNA fame said "In the last analysis, there are only atoms. There's
just one science, Physics; everything else is social work" in
his lecture at the London Institute of Contemporary Arts in 1985.
This view is also echoed by Stephen Hawking and Steven Weinberg.
Hawking nicely summarizes this view as: Biology->Chemistry->
Physics, in the book "The Large, the Small and the Human Mind".
Steven Weinberg says in his book "Facing Up", p-22-3: "No biologist
today will be content with an axiom about biological behaviours
that could not be imagined to have a more fundamental level.
That more fundamental level would have to be the level of
Physics and chemistry, and the contigency that the earth is
billions of years old". Biologist Richard Dawkins (in "The Blind
Watchmaker") states that Physicists have to come into the scene
at the end of the long chain of reasoning to explain evolution
of life to complete the last but not the least significant step.
Molecular Biologist Franklin Harold says in his wonderful book
"The Way of the Cell", p-4: "We have ample reason to believe
that every biological phenomena, however complex, is ultimately
based on chemical and physical interactions among molecules"
and reinforces this in his epilog : "The bedrock premise of this
book book is that life is a material phenomenon, grounded in
chemistry and physics. Physicist Heinz Pagels wrote in his book
"The Dreams of Reason", p-49: "Biological systems are extremely
complex Quantum mechanical entities functioning according
to well-defined rules". Zoologist and award winning science writer
Colin Tudge says (Independent on Sunday, Jan 25, 1998): "There are
no biological laws, apart from the underlying laws of physics,
and technology might anything that does not break these bedrock laws".
In the book "Our Living Multiverse: A Book of Genesis in 0+7 Chapters",
alternately titled as "Origins of Our Existence : How Life Emerged in
the Universe" author Fred Adams (Univ. of Michigan Physics Professor)
writes:
Let me digress more into this issue as it is vital to the
"Darwinian" view of life. By Darwinian I mean the view that life is
a product of natural process (i.e processes governed by the laws of
physics). It is now understood that the fundamental constituents of
matter (electrons, quarks) follow the laws of physics. It is also
understood that matter, living or non-living, are composed solely
of these fundamental elements. No life forms (dead or alive) has
been found to contain any element other than these fundamental
elements.
Now if we know that the individual elements obey the laws
of physics then it stands to reason that an aggregate of these
constituens must also be subject to the laws of physics. If one
electron, quark or string obeys the laws of physics then a system
of n electrons and quarks (n is very large, for a living
object) must also act according to the laws of physics. To say that
a human is not just a product of the laws of physics but more, is
NOTHING BUT that old vitalism in disguise. There is no third
possibility. Either physics or an unknowable entity (God/Soul..)
dictates the actions of the system of electrons and quarks called
humans. I am not saying that all is known about physics. The
knowledge of physics itself is a continually expanding horizon.
By Physics in this essay I will mean tht totality of known and yet
to be known laws that govern the evolution of the universe.
Now let me clarify a VERY important point. Just because life
is governed by the laws of Physics, that doesn't mean that every
aspect of life can be DERIVED by the laws of physics. Let me illustrate
this point with a very simple example. We know particles/objects
obey the laws of gravitation. Using the laws of graviation we can
precisely predict how a two particle system (like a star with one
planet) will move. The orbit can be predicted precisely, or conversely
the observed trajectory of two particle system can be explained
precisely by the equations of gravity. Now just add one more particle
to this system. No one can PRECISELY predict the exact orbit that
a three particle system. That is because the laws of gravitation
are non-linear. A non-linear equation cannot be solved exactly. So
the observed trajectories of the particles in a three particle
system cannot be exactly explained/derived by the laws of
gravitation. Do we then say that a miracle/divine force is
governing the three particle motion? Obviously not. Even though the
observed trajectories of the particles cannot be explained/derived
by the laws of gravitation, the important fact is that they do not
violate the law either. And since there is no evidence that a third
unknown force enters into the picture as soon as a third particle
is added to a two particle system, thus the fact still remains that
the laws of graviation determine the trajectories of three or any
number of particles, even though we can only derive the
trajectories of only a two particle system. Now extend this
argument to humans. A human is enormously complex system of
trillions of particles interacting with not just gravitational
force but electro-weak and strong forces as well. If we cannot
even precisely determine the behaviour of three particle systems,
it would be naive to expect to be able to explain the behaviour of
a human being in terms of the laws of physics. There is no
fundamental difference between living and non-living matter, the
difference is due to the complexity and emergent effects. Laws of
Physics do control the behaviour of all matter, living, or
non-living. No vital prcesses of a living organism, viz.
metabolism, reproduction etc, involve any mechanism that violates
or does not follow any known laws of Physics, like the law of
conservation of energy, law of entropy etc. And since no living
object has displayed any property that has violated the known laws
of physics, we can draw the conclusion that that any property
(including emotions, beliefs etc) of humans are ultimately DUE to
the laws of Physics. To deny that will clearly be tantamount to
invoking some mysterious force somewhere (Like in some religious
texts, a "soul" is said to be implanted into the embryo at some
point). In the evolutionary paradigm, life and death of any life
forms are different states of matter. No mysterious force enters
into a living body and leaves the body after death. Non-living matter
(including a corpses) are in thermodynamic equlibrium, living matters
are in highly non-equlibrium thermodynamic state. Just as a piece
of iron can be in a magnetized state or non-magnetized state with
no change in its material composition. Or just as a computer running
a program is one state of the computer and a computer shut down is
another state of the computer, with nothing entering or leaving the
computer. One can say that that a human started and stopped the
computer. But that human is also a system governed by the laws of
physics and the human+computer system is thus acted on also solely
by the laws of physics which cause the human to start and stop the
computer (Alternating between two states). EVERY PHENOMENA in
universe is coded into the laws of physics. Our entire universe is
a system of incredibly large number of systems of particles (of
which a human is a subsystem). A human is a very specialized
complex system, and the laws of complexity determines its state,
including the state of being alive or dead. It is the laws of
complexity that give rise to the action of death genes responsible
for the natural death of humans.
All this may sound like the much dreaded idea of reductionism, but
reductionism or wholism is a term coined by arm chair philosophers,
not scientists. There is no *scientfic* concept called reductionism
or wholism. Science is about seeking and formulating statements of
(tentative) truth about reality based on the best evidence available.
The fact that even in physics sometimes the whole is not just the
sum of its parts in the sense that the precise motion or properties
of an aggregate is not exactly derivable in terms of the properties
of the individual constituents, can be labelled wholism, but that
labelling does not dismiss the fact that the properties of the
whole is still ultimately due to the properties of the fundamental
constituents, not something beyond the laws of physics. The motive
behind coining those labels is the same, a subtle attempt to retain
a semblance of some "divine" factor in life, a refusal to accept
that life can be totally a result of natural process. By denying
that biology is a consequence of physics, they wish to leave open
a divine intervention on biological process (thus life) not
explainable by or subject to natural laws.
Now on to the main theme of my essay, which is the implication
of this simple, yet profound insight. One immediate implication
is the illusion of "I/me/we". When"we" say "we" there is an implied
existence of an entity beyond our physical body, acting as a
driver/engine of "our" body. "I" will stop quoting "I", "we"...
from this point on for simplicity, but I will use these words in
the sense of an identifying label. But as it should be clear now
that there is nothing external or internal to the physical body
dicating the action of human body that is not part of the
body itself. In fact consciousness is an emergent property of
matter, brain in this case. Emergent properties are manifestations
of complexity in chaotic systems, i.e systems that follow
non-linear equations and are composed of large number of elements.
Such systems exihibit consistent patterns that can be described
quantitatively (by the laws of complexity) but because of the
inherent non-linearity of the underlying laws of physics, the laws
of complexity cannot be derived in terms of the laws of physics
exactly. Human brain is the prime example of a complex system. It
is not just a random collection of billions of neurons, but an
organ that is a result of millions of years of evolution, thus
ultimately a product of the laws of physics. And the synaptic
connections of the brain in the cerebral cortex is a result of
hundreds of thousands of years of evolution. And it is the synaptic
connections the brain that endows it with the emergent property
called consciousness, unique to each individual because of the
uniqueness of the synaptic connections of each human brain. This is
what neurologist Joseph Ledoux calls
The Synaptic Self. When we refer
to I or we, we are really referring to the synapatic connections of
the I/we. Our every action and thought (Which defines a person) is
ultimately determined by the laws of physics through the medium of
the synaptic connections of the brain.
The implication of the above is that there is no intrinsic meaning
of the notion of "Free will". Whatever act we commit or whatever
we think/believe are the ultimate result of the laws of physics.
If we carefully stare at the cliche "Yes, we can do whatever we choose
to do, we have free will, humans are not robots, they are thinking,
living beings with mind, emotions and sense of right and wrong and
ability to choose between them" we will see the fallacy in it. All
the "we's in those statements really refer to the person's brain.
The free will itself is an outcome of the laws of physics working
in the brain. Just because we have an illusory perception of free
will, that does not change the fact that every act and thought are
ultimately determined by the laws of physics. Yes, humans do have
choices available, but which choice will be made in a given
situation is ultimetely determined by laws of physics. We may have
the illusions that "we" made the choice freely, but as I argued the
"we" itself is a system that works according to the laws of physics.
There is no player other than the brain and the laws of physics in
the matter of choice. A free willed choice is an illusion inside the
brain of the human making that choice. There is no will free from
the laws of physics. We are truly puppets on a string. The string
being the "Laws of Physics", or "string" theory (no pun intended).
Some proponents of free will invoke the randomness inherent in
in all of nature's processes to justify the existence of free will.
That is a flawed position. For one thing randomness is a relative
notion. With the entire universe being a large syetem with large number
of elements, one part may seem to be random with respect to another
part. But the entire universe as a whole is determinsitic, governed
by the laws of physics. There is no random act that occurs
violating or not required by the laws of physics. The timing of the
individual decay of a quantum particle appears random and can only
be predicted statistically by Quantum Mechanics, but that does not
mean that the decay happened due to some non-physical cause.
Randomness is an epistemological notion reflecting limitations in
our complete understanding of the underlying reality, not a
fundamental notion of physics. Secondly even if the randomness was
beyond physics, the free will due to randomness will still be not
determined by the brain/body of the person exercizing the free will.
The free in that case may be free from physics, but not free from
whatever is causing the randomness. So either way the notion of
free will dissolves into meaninglessness, because the very notion
of free will implies the existence of an independent driving force
beyond physics that causes a human to make choices, essentially
equivalent to proposing a "soul" hypothesis and the free will is
then relegated to the soul of that person.
Another implication of the natural view of life is that morality
or ethics are also the result of the laws of physics and thus have
no intrinsic meaning. The "should"s or "oughtta"s are instincts
instilled into the brain by evolution, and thus by physics. We often
hear the cliches "Morality is not subject to scientific laws", as if
morality is subject to some "other" laws. This statement is vague
in itself. But the simple fact that morality is due to an instinct
instilled by evolution immediately makes it clear that the origin of
moral instincts is coded into the laws of physics. The causal chain
is : Physics-->Evolution-->Brain-->Morality. And it is evolution which
instils a "should" in our mind. There is no intrinsic criteria of
morality outside and independent of physics. Morality is the
overall sense of right and wrong instilled into the brain of human
species through evolution. There can be variation in that moral
instinct in individual humans within human species, but
statistically the morality among the species as a whole is such that it
helps to preserve the species. And morality also can change and adapt
due to evolutionary pressure. We often hear religious believers justify
belief in God by raising the question that without a belief in God
how can there be morality, and wouldn't humans and society in
general slide into immorality and chaos? The fallacy in this
argument is that morality will be there, regardless of religious
belief, as morality is a product of evolution. In fact even
religious belief itself is one form of evolutionary strategy for survival.
Religious morality is rooted in the more fundamental evolutionary
instinct of morality, although the religious believers have the illusion
that their moral beliefs are due to a belief in God's commandments. The
moral instinct, being a product of evolution, is present in theists
and atheists alike in varying degrees. The only thing belief in
religion adds is a set of ritualistic practices and behaviour
peculiar to a religion. There can be individual variations of
morality among humans, so there will be instances of individuals with
no sense of morality, or different from the average. For many who do not
believe in God (in the traditional religious sense) and understand
that there is no objective basis of morality, they still feel a
strong inherent instinct against committing certain acts. They cannot
justify with absolute reason, why they should not commit those acts,
but nevertheless cannot commit those act either. Even those who
understand that their moral senses are due to evolution, also feel
the instinct of right and wrong and act accordingly. It is a
curious thing, but there is no contradiction, in fact it is all
self-consistent. Again a stark reminder that each human is a system
of particles obeying laws of physics, irrespective of their beliefs.
Even if for some reasons all humans suddenly turned into atheists,
humans species (via the laws of physics) will always find a way to
enforce some standards of morality, purely for evolutionary survival.
Human species will not allow itslef to self-destruct, physics does
not admit of that solution of it's equation, figuratively speaking.
A human is a very special system of particles having a property
called consciousness capable of making a human appreciate that they
are a system of particles run by the laws of physics. Not every
human can realize this capabilty of appreciating this fact however.
Philosophers of science have always been intrigued by
this so-called consciousness loop :
Physics-->Evolution-->Consciousness-->(Discovery of) Physics
It is indeed intriguing to realize that this circular chain
is due to the laws of physics (that human mind can discover
laws of physics is also rooted in physics!). It is all internally
self-consistent.
The same is true for instincts of fear/anxiety. They are also
hardwired by evolution in the primitive part of the brain.
Rationalism, which is a byproduct of the evolution of human brain
in the cerebral cortex and has no causal effect on those instincts.
So one can be rational and but still have an instinct of fear,
like afraid of staying alone in a deserted house, just as one can
feel the instinct of morality without believing in God or on any
absolute criterian for morality. Fear of the unknown is an
evolutionary instinct. So is love, and in fact all emotions.
Passionate champions of humans rights can refute religious beliefs
and justify a secular approach to morality and human rights,
using such expressions as "human spirit is noble" "love is supreme"
etc. But at the end these are appeal to emotions, not a cold, hard,
logical positions. All that matters is what evolution instills in
the brain on the average. Of course evolution itself creates this
necessary tension between two opposites. Tension is essential to
stability. This fact has been acknowledged by scientists in the
light of evolution and a detailed analysis of mathematical
modelling of the evolutionary mechanisms. We know by this insight
that if each member of human species were completely honest or
dishonest, or kind and generous, or extremely violent or malicious
that will not be evolutionarily stable and will lead to self
destruction of human species. Evolution requires a stable and
optimal distribution of evil and good. This is a purely mechanical/
natural consequence of physics. A simple example of that would be
the hypothetical situation where there is barely enough food for one
to survive and there are two starving good people. They will both
die rather than one eating the food and letting the other die.
Similarly a society with all liars or all truthful will also lead
to an evolutionary instability. The most stable state is some liars
but majority truthful in varying degrees. The fact that most people
believe lying is wrong, and telling the truth is right, is also a
consequence of evolutionary mechanism to create that stable state.
Evolution will not allow all humans to become philosophers or
religious extremists either. That stabilty requires a statistical
variation is one of the most profound insights of evolutionary
science. Evolution requires inequality for survival of some. If all
are equally strong, they will mutually destroy each other. If all
are weak, they also will eventually self-destruct also. A
distribution of the strong and the weak is a necessary(evil) so
that some may survive. This is the hardest lessons of evolution to
assimilate. This fact of evolution, natural selection, was used by
some in the past to promote social inequality and eugenics (started
with Herbert Spencer in Victorian England). That was a fallacy of
promoting an "is to an ought" also known as naturalistic fallacy.
The fact is that what is in nature cannot be justified as right or
wrong. Nature will be whatever it will be based on physics. The
fact that such views of Darwinism didn't hold up only points to the
fact that evolution does not favour eugenics, hence such views
(called social Darwinism) got weeded out by evolution itself. We
have to credit physics for the demise of social Darwinism, if we
have to. The lofty talk about triumph of humanity or human spirit
etc to explain that is just a metaphor of language.
Humanists can passionately call for an utopian world of humans
devoid of any ill feeling, full of love for all. But such utopian
state of all ideal humans is not consistent with the laws of
evolution i.e physics. But the yearning and passionate struggle to
achieve that utopia is not. That urge is part of evolution itself
Also just like the instincts of morality and fear, an appreciation
that all such yearnings for idealism is produced by evolutionary
forces does not result in a loss of that instinctual yearnings.
That is the paradox, if you will, of evolution/physics. An
understanding/discovery of the laws of physics cannot affect or
alter the laws of physics!.
One may get the feeling that all this talk about life and human
emotions being nothing but the result of the laws of physics takes
away the mystique, the romanticism of human imagination. Nothing
is further from the truth. Alert reader may have noticed no mention
has been made as to the origin/evolution of the laws of physics.
With so much talk about the insights into the natural root of
life and its various aspects, the fact remains that the origin of
the laws of physics is not known or is knowable. That is the
ultimate mystery. It is not knowable because the laws of physics
are the only tool humans have at their disposal (tested and
beautiful) to seek the truth about reality, the truth that can be
shared among humanity that is independent of one's belief,
affiliation, color, race etc. Obviously understanding the origin
of the laws of physics is not possible using physics as a tool.
So this very existence of an ultimate mystery will be a permanent
source of a sense of wonder and mystical feelings among those who
appreciate the beauty of the workings of the laws of nature. The
laws which not only give rise to the fragrance of a flower, or the
fascinating patterns of a snowflake, but also the ethereal quality
of love in humans. The laws which create in the brain a sense of
wonder at the working of the laws, and creates a sense of wonder
at the creation of a sense of wonder at the working of the laws....

Since the publication of The Origin of Species and The Descent of Man
by Charles Darwin, biologists have come a long way in their quest to
understand human behaviour, building up on Darwin's original ideas and
revising/perfecting it with new evidences and observations. Age old
questions what is love?, where do human
morality stem from etc are now
understood reasonable well thanks to the research of sociobiologists and
evolutionary psychologists,specially in the last two decades of 20th
century. Their work points to an entire gamut of human emotions being
rooted in our evolutionary history. Love, like all other human emotions
is also rooted in the evolutionry history. It should be noted that
evolutionary psychologists use the term love and sex interchangeably to
mean the feeling of romantic attractions, courtship, mating and and the
act of sex between opposite sexes. The term love and sex will be used
interchangeably in this greater sense throughout this writeup. This
writeup is by no means a scholarly or a scientific essay. Instead my
aim is to quote some of the scientists and science authors (in books
and TV shows) with my annotations to provoke the readers to read up on
these fascinating issues further. No attempt is made to organize or
structure it in any way. Needless to say the findings of Evolutionary
Psychology (EVP) will sound shocking to many. But science is about
truth, not about political correctness.That's how it has to be seen.
A slew of well written books and essays have been written by many
experts in evolutionary psychology on this topic. The works of David Buss,
Helen Fisher, Geoffrey Miller, Robin Baker and many others are worth
mentioning. TV shows like the Science of Sex (TLC), Gender Wars
(Desmond Morris) etc are also quite illuminating.
What is the root origin of love? The surprising but simple answer is
the urge for the survival of genes. And what is the basis of the
survial of the genes? To put it rhetorically, its the laws of Physics
(stupid). We may not realize this origin when reading or listening to a
beautiful love poem or song. To quote from "Mystery Dance: On the
Evolution of Human Sexuality" by Margulis and Sagan('91):
The survival of genes require the physical survial of an animal to
reach reproductive to be able to choose a mate to pass off the gene to
the offspring. It is the send step that lies at the origin of love,
courtship of love to be precise. Darwin touched this aspect in the idea
of sexual selection in the Descent of Man. But this idea find its
fullest exposition in modern evolutionary psychology(EVP). Males and
females choosing each other for specific attributes drove, through
sexual selection the evolution of such human features as brain size
increases, sexual organ characteristics and human behaviors in general.
Many of modern courtship techniques have parallels in evolution, like
the long tailbones of peacocks, which have grown large to attract
peahens, since peahens in turn were attracted by long tails of peacocks.
To quote Margulis and Sagan:
As revolting as it may sound, infidelity(cheating) in love,
jealousy,rape etc are also rooted in evolution and evolutionary
psychologists deal with these topics too in their research. In
their book "The Natural History of Rape" Thornbull and Palmer
explains the origin of rape as an evolutionary adaptive mechanism
to maximize gene propagation. Quite predictably they evoked
strong reactions form critics. But most of their critics
committed the Is-Ought logical fallacy, believing that just
because something has been classified as "natural," it must also
have been implied as morally okay. But Thornbull and Palmer did
not imply that. This linking of rape to evolutionary adaptation
is cited on page 45 of the book "Sexing the brain" by
neurobiologist Lesley Rogers quoting another biologist Matt
Ridley:"Rape was evolutionarily adaptive"
Cheating in love is also evolutionarily rooted. Cheating is in our
genes, narrates Ms. Kathleen Turner in The Science of Sex(TLC). So it
must have evolutionary advantage in our past. With huge quantity of
sperms in men, its to their evolutionary interest to father as many
children as possible. With one egg per month women has less advantage
in infidelity, yet it does exist, so must have some advantage. More
resources for her child through the extra mate is the explanation for
female infidelity. It provided genetic advantages to both males and
females in evolutionary past (and still does today). This fact of
evolution is also cited in Joann Ellison Rodgers' tome:
"Sex: A Natural History" on page 215:
Curiously, Evolutionary Biologists have found a correlation between
degree of female infidelity with the quantity of sperm (testicle size)
of the males of a species. Humans lie between the two extremes of
Gorilla (least likely to cheat, small testes) and Chimpanzee (most
likely to mate with multiple partners, largest testes).
This correlation has been cited in the TLC TV show as well as
on page-339 of "Sex: A Natural History":
Another insight from EVP is that humans are not evolutionarily adapted
for strict monogamy. As biologist Meredith Small points out on p-17 in
her book "What's Love got to do with it" that women, as well as men,
might not be biologically designed for monogamy citing that only 14% of
the 200 species among primates are monogamous.
In her book "The Anatomy of Love" Helen Fisher writes:
Polygamy is also roughly correlated with male to female body size
ratio, which in case humans suggest a moderate polygamic tendency,
as cited by Meredith Small (What's Love got to do with it) on
page 20: Women are 80% of men physically,suggesting mild polygamy.
Rodgers also mention this correlation on page-338 of her book.
All this shows that humans are at least not designed for strict
monogamy or strict harem system either.
Jealousy also is evolutionary in origin. As David Buss points out in his
book "The Dangerous Passion: Why Jealousy Is Necessary in Love and Sex"
and also in the TLC show on Science of Sex that we are here because our
ancestors were jealous. Those who were not did not leave any descendents.
Needless to say that does not mean that TODAY EVERYONE has to be jealous.
Apart from the fact that evolutionary traits are statistical, the
evolutionary needs also change slowly over time as part of evolution.
An important element in sexual selection is body odor. Each of us have
unique odor like fingerprint, which serves as fitness marker in
evolutionary paradigm. Margulis and Sagan mentions that on pages 179-80.
They also mention body odor as a sign of healthy immune systems. They
cite an experiment of sniffing effect of sweaty male T- shirts by women.
As the evolutionary root of that they mention that our mammalian
ancestors were nocturnal, so had to depend on sniffing as primary mate
selection means.
In the "Anatomy of Love", page-42, Helen Fisher writes:
Scientists have identified the hormone that carries this distinct odor
in men (generically called pheromones) called androsterone and the
detectors for that odor in women called VNO (Vomeronasal organ). This
confirms that humans also use sniffing (but in a much more subtle way)
like animals to check out their mates instinctively via their VNO.
It should be pointed out that the pheromone sniffing is not consciously
done, the usual stinking male sweat is not due to the male pheromone
in his sweat, but due to the bacterial degradation in his sweat that
is exposed to the atmosphere for some time. That smell is conscious and
made through the usual olfactory nerve, the instinctual smelling of
pheronome in sweat is through VNO bypassing the olfactory nerve.
Why do women have cryptic estrus (Concealed ovulation)? The reason cited
for that by Margulis and Sagan on p-197 of their book is that it helped
male bonding with their women in the evolutionary past. The TLC series
"The Science of Sex" narrated by actress Kathleen Turner also mentions
that concealed ovulation helped pair bonding in our evolutionary past.
Basically by hiding when she is infertile she forced the man to be
always around her because he feared she would be mating with another
man and sire child with him, and him having to take care of that child.
That the feeling of love is triggered by some features in males and
females which is perceived as beauty or sexiness is obvious to anyone.
But these markers are programmed by evolution as markers of some
fitness. This is the finding of evolutionary psychologists. The work of
Devandra Singh of UT Austin pointing to Waist to hip ratio as an
evolutionary marker for healthy pregnancy is cited by Rodgers. Men are
sexually attracted to low waist-to-hip ratios in females, and a low
female waist-to-hip ratio really correlates with youth, fertility,
and health. On page 148 of "Why We Feel? The Science of Emotions" Evol.
Psychologist Victor Johnston mentions that a hip/waist ratio of 0.7
signifies an ideal androgen/estrogen ratio required for fertility in
women. So is lip-fullness. So the perception of beauty and thus sexual
attraction is directly correlated with female fertility. For men one
fitness marker is facial symmetry, thus women tend to prefer men with
facial symmetry. Reference to this can be found on p-49-58 in Lesley
Rogers' "Sexing the brain" quoting Randy Thornhill's theory of beauty
and symmetry vs. fertility. In this context fitness should be
understood as genetic fitness,good genes in simple terms. Again just to
remind these preferences are instinctual and thus women will not be
consciously aware of this.
Artistic creativity like music and painting,
aesthetic sense,
humor,athletic ability, and intellectual activity has all been
identified by some evolutionary psychologists as the product of sexual
selection. In fact they attribute the relatively large size of human
brain to sexual selection pressure. Costly organs (brain consumes a lot
of heat) serve as fitness markers. The pioneering work in this are is
by Geoffrey Miller who has written a highly readable book titled "The
Mating Mind: How Sexual Choice Shaped the Evolution of Human Nature".
He contends that women view these abilities as markers of genetic
fitness in men and that women's brain has also evolved to be able to
discriminate these abilities in men. According to him, since all those
qualities do not give them an obvious survival benefit, they must have
provided and continue to provide a reproductive advantage to have
survived and thrived. "Romantic" behavior like the making of complex
art couldn't have aided our ancestors find more food or avoid predators.
Thus it might have helped to serve as a marker of fitness of primitive
men to primitive women with whom they wanted to mate. Of course the the
romantic behaviours in primitive time were also primitive, and has
evolved to its modern form.
When it comes to love and sex mention must be made about the battle
of the sexes and mate competition. Biologists have traced
these to sperms. Robin Baker has done detailed study of how sperms
compete with each other to fertilize eggs. That competition is a
sort of miniature version of the competition among males for a mate.
Matt Ridley in his book "Red Queen" traces the origin of the battle
BETWEEN the sexes (and the resolution thereof) to the evolutionary
battle between male and female gametes that led to sex differentiation
in the first place.
I have glossed over these fascinating new horizons of evolutionary
psychology, which has taken up the most daunting task of humans trying
to understand humans. Why are we the way we are. It is a dynamic
new area of research and is sure to unravel age old mysteries of
human behaviour nothwithstanding the stiff resistance from the
PC police.
"Now, this formulation has a comforting feel to it, but it makes no sense
at all in terms of either material or imaginable entities, which is why Kant,
even apart from his tortured prose, is so hard to understand. Sometimes
a concept is baffling not because it is profound but because it is wrong.
This idea does not accord, we know now, with the evidence of how the
brain works." (referring to Kant's idea of categorical imperative)
"Although many past cases of sunrise do not guarantee the future
of nature, my experience of them does get me used to the idea
and produces in me an expectation that the sun will rise again
tomorrow. I cannot prove that it will, but I feel that it must."
Both these instincts(or feelings) are shared by all humans, LRS or NLRS.
Then instinct of God and immortality is universal. It exists throughout
humanity in general. Feeling of an instinct is not dictated by logic,
and is also not contrary to logic
either. How one interprets those instincs and proposes a theory may be contrary
to logic. Feelings like fear, sense of mystery, awe are not controlled or shaped
by logic, but THINKING is. If one interprets those instincts to believe in
specific religious scriptures as being the word of God then that is against
logic and reason. Believing in the revelations of religious scriptures
are not purely instinctive. These beliefs are inherited by people
from the socio-religious roots or surroundings that they are
brought up in. They never believe in it from first hand experiences nor
by the first hand associations with the prophets. Such beliefs originating
from human indoctrination can certainly be contradicted by logic.
Rationality is rather supposed to be a guide in an objective evaluation
of subjective "claims" and for seeking the truth by consensus. But a
personal belief in something plausible which does not contradict or violate
natural laws (This is the all important qualifier) is NOT inconsistent
with LRS. Similarly a generic prayer to an abstract God (again not a
religion specific prayer) certainly does not contradict logic as such
prayer reflects an instinctual reflex to form an abstract mode of
communication with an abstract God. It is possible that a rational and
scientific person when in dire illness can begin to believe in an abstract
God and "pray" to such a God. It is purely an instinct/reflex, not does
not have to be due to a conscious change of perception through reading
scriptural revelations. Instincts/Reflexes are biologically rooted and is
not subject to rationalization in crisis. It is a hardwired defense mechanism
in the genes that give rise to such faith so that a placebo effect can result
from the faith and possibly lead to healing. Altered states of brain can
affect anyone, LRS or NLRS, in crisis. Any resulting healing itself does
not prove the existence of God. It only shows the ability of brain to
impact the well-being of the body.
On The Nature Vs. Nurture Debate:
Do Genes Or Environment Determine Human Behaviour?
- Aparthib Zaman
"Neuroscience is showing that the brain's basic architecture
develops under genetic control. Brain systems show signs of
innate specialization and cannot arbitrarily substitute for
one another"
"What the genes prescribe is not necessarily a particular
behaviour but the capacity to develop certain behaviours and
more than that, the tendency to devlop them in various
specified environments"
Propensities are reflected in thoughts and feelings that act
find expression through natural and spontaneous behaviours
called traits. But certain behaviours (i.e actions) can be
forced by environments to be counter to one's natural genetic
propensity.
"Culture is ultimately a biological product" (p-107)
"Babies do not kill because we do not give them knives and
guns. The question we have been asking, how do children learn
to aggress? But we should ask how do they learn not to agress."
We see many examples that further contradict the myth that
human mind and behaviour is formed through learning. We see
people becoming religious when not subject to religious
teaching or brainwashing, and people become atheists despite
heavy religious indoctrinations. One exception should break a
rule. If values and mental inclinations were leraned and taught,
the such exceptions could not occur.
A SCIENTIFIC VIEW OF LIFE, DEATH &
IMMORTALITY - Aparthib Zaman
The first step in the creation of life is the occurrence of Big Bang
and the existence of the Laws of Physics as represented below:
|----->Laws of Physics
1. ? ---->|
|----->Big Bang
OR,
? ----> Laws of Physics ----> Big bang
Now to go to the next step, let us first state an important
scientific insight: That the laws of chemistry are rooted in
the Laws of Physics, and the laws of Biology are in turn rooted
in the laws of chemistry and to the laws of Complexity, i.e
Emergent Laws, in particular the laws of non-equilibrium
thermodyamics in the context of life's origin. In other words
the origin and evolution of life is rooted in the laws of Physics:
Laws of Physics ---> Laws of Chemistry + "Laws of Complexity" ---> Laws of Biology
These same laws of physics instigate the development of
life, including complex creatures such as humans, at least under
favorable circumstances. (p-191)
"We now know that the laws of Physics ultimately determine
the behavior of chemical reaction and biological processes."
(p-192)
The consummate example of emergent behavior is life itself. In
simple reactions, biochemical molecules behave according to known
chemical pathways. When these molecular systems become sufficiently
complex, they act in novel ways. After this emergent level of
complexity reaches a critical threshold, the system becomes alive.
But the details of this transition remain shrouded in mystery. In
spite of this gaping hole in our understanding, however, biological
processes are driven by the same laws of physics that describe
stars and planets. The concept of vitalism -- the idea that
biological laws are independent of physical laws -- has been
safely relegated to the trash heap of outdated ideas. (p-193)
From Back Flap:
With so much talk about the frontier of biology these days, I
welcome the occasional reminder that the laws of physics control
the formation and evolution of life.
- Neil DeGrasse Tyson, Director, Hayden Planetarium
As a final example renowned biologist Earnst Mayr wrote in his book
"The growth of Biological Thoughts ('82): "Every biologist is fully
aware of the fact that molecular biology has demonstrated decisively
that all processes in living organisms can be explained in terms of
Physics and chemistry"(As cited in Weinberg,"Facing Up", p-19)
NOTE: It is not known if the Laws of Complexity, the Emergent
Laws as shown above are independent laws or follow from the basic
laws of Physics. Most reductionist scientists believe that they
are indeed the consequences of the Laws of Physics, others like
Nobel Laureate Chemist Ilya Prigogine,
late Biologist Robert Rosen,
and physicist Paul Davies take a holistic view and think that they
are additional laws of nature, that cannot be reduced to the laws
of physics, they exist of their own. Ilya Prigogine takes the
view that emergent laws start at the top and work downwards
(Complex to simple), whereas laws of Physics start at the bottom
and work upwards (simpler to complex systems), meeting somewhere
at the middle where life (or any dissipative structures) emerges.
Prigogine got Nobel prize in 1977 for explaining and discovering
dissipative strutures, of which life is the prime example. It is
the emergent laws of complexity that is the cause of
self-organization, a characteristic of life. However the Laws
of Complexity have not been actually derived from the Laws of
Physics, even if they were rooted in them as the reductionsists
believe, due to the sheer complexity of the number of molecules
involved. But it is important to realize that both viewpoints
share the common belief that biology is a result of material
process, i.e a product of natural laws.
Now let me outline the remaining steps leading to the "mystery"
(rather the unsolved problem of life):
2. In step 2, simple matter was created after the Big Bang due
to the action of the Laws of Physics (Quantum Fluctuation:
Big Bang --> Laws of Physics --> Simple Matter (atoms, simple molecules)
3. In step 3 simple matter is again subjected to the laws of Physics
to form Composite matter (Complex molecules) whose behaviour is now
described by Laws of Chemistry:
Simple Matter + Laws of Physics --> Composite matter (Laws of Chemistry)
4. In step 4, composite matter is subjected to Laws of chemistry + the
laws of complexity (i.e Chemical evolution) to form living molecules
(Self replicating molecules) and primitive organisms, governed by
laws of biology:
Composite Matter + Laws of Chemistry + "Laws of Complexity" --->
Cells, primitive organism. ( Laws of Biology )
5. In step 5, primitive organisms are subjected to Laws of Biology and
laws of complexity (i.e Biological Evolution) to form higher (complex)
organisms:
Primitive Organism ---> Laws of Biology + Laws of Complexity
(Biological Evolution)
---> Advanced Unicellular/Multicellular Life.
Life is an EMERGENT behaviour of matter. Life is a result of
self organization of matter driven by the requirements to
maximize entropy by reducing the gradient of temperature
difference between sun and earth. Life is not simply an entity
created from scratch from conception to birth. Life is an
evolving process that has been going on over billions of years
in an incremental way. Our body may have been formed in matter
of years after conception, but the program (our genome sequence)
that builds us (our body+mind) has taken billions of years to
perfect. The most insightful discovery by Darwin was that
natural selection and mutation can give rise to a complex life
form as human through a prolonged and cumulative action of those
laws. The complicated body and brain of ours are not just a
creation from our birth to date. We have inherited the blueprint
of life (the genetic code) that has evolved and perfected
through billions of years of evolution. That's why life is so
precious. It contains huge information collected over an
incredibly long span of time. Our genome sequence will take
thousands of pages to write down in paper. Like a complex
software that starts with few simple lines but eventually is
perfected into a sophisticated program of millions of lines with
contributions from many people over a long time, the genetic
code of life and the genome took billions of years to be developed
and is still evolving. Life will look different and more advanced
in another million years. We can never understand life without
understanding the history of how life has evolved from the
primordial earth with single cells giving way to more and more
complex organisms by incremental steps. But the process of this
evolution of life from simple to complex is purely natural. Down
at the bottom it is nothing but physics. Natural selection and
mutation is nothing more than a manifestation of the laws of
Physics at work at the most fundamental level of matter. As
molecular biologist William Clark says "Natural selection
ultimately adheres to the same principles of thermodynamics
that govern all other activitiesin the physical universe;
evolution is simply an epiphenomenon perceived by humans"
(p-43, The Biological Basis of Aging and Death)
One may say that creation of a complex thing must be due to
intelligent design, not just blind laws of physics. This is an
analogy from life where we see humans (intelligent being) design
complex things like watches. But humans employ the same laws of
Physics to design complex things. And even laws of Physics
without intervention from humans can design beautiful things,
like snowflakes, flowers etc. Humans themselves are product of
laws of physics, so even human designs are ultimately designs of
laws of physics. Only that we don't know the "designer" of the
laws of Physics (The ultimate mystery). We don't even know how
to meaningfully frame the question at this extreme level.
Now coming to the common question of what is death, and what
happens just after death, when nothing seem to be different in
the body just before and after, what is "missing" and where
did "it" go? The first question is a scientific question, not
a metaphysical one. Lets take an analogy. Say you have a music
tape. When you play it in a player it plays beautiful music.
Now say accidentally someone pushed the record button with no
input, so the entire music gets erased. When you play the same
tape again, no music will be heard. The tape looks the same.
What is missing from the tape, "where" did "it" go? I am sure
this doesn't provoke a metaphysical question in one's mind. The
case of the death of human, or any animal is not much different.
Just as in the erased tape, many individual tiny magnetized
particles were oriented in an ordered pattern before the tape
was erased, and lost their orientations after, the cells in the
human were alive before death, and dead aftre the death of the
human. A cell is alive when it carries out metabolism, and dead
when it ceases to. The brain cells of dead human all die (loses
metabolism) first, then slowly the cells of other organs decay, due
to the lack of oxygen. Cells in the organs like eye, body limbs die
slowly, so if they are removed promptly before decay starts and
preserved, they can be reused by other human, just as the parts
of a computer whose CPU is damaged can be reused in another
computer. Is there a soul? That is a vague concept, fraught with
logical absurdities. All we have is mind/consciousness, which is
the emergent effect of the brain cells in live action, much like
the music in a tape which is the effect of the complicated
magnetic patterns in it being passed through a magnetic head.
Stop the tape, and the music stops too. Mind/consciousness is
like music playing due to the trillions of cells in human brain
running the genetic code tirelessly. Each individual life has
not much significance to the universe or to "?". The only
significance of each life is in maintining continuity, a link
between its predecessor and its successor. The notion of
soul is completely created by our desire for immortality. As
grim as it may sound, there is not even a logically consistent
DEFINITION of soul, let alone its existence, beyond the physical
body (specially brain). Is there life after death? Some
questions need to be answered first before even trying to answer
that. How can one define life AFTER death to begin with? If
that new Life after death must require the same material body
then what age should that body be? What if someone dies at age 6.
Will he/she continue life after death or be resurrected at 6?
What if someone dies at 90? Will he/she be resurrected at 90?
Will the resurrected body age again? If not then what is the
meaning to be alive at 90 forever or at 6? Finally does the life
after death need not require a body, if so, what does it mean to
be alive without a body? Unless one can answer these questions,
the vague concept of Life after death will be a reflection of
the refusal to accept death as a permanent destruction of one's
body and brain. All scientific and logical reasoning points to
an absurdity of resurrection in the way humans wish to look at it.
The only thing that can survive the body is some information (If
it is saved), for example if tape is destroyed the same tape can
be reconstructed (recorded), if the music itself is saved in say
an .mp3 or .wave file. (Which is information). Likewise, for the
human, it is the complete genome sequence + the complete
neuronal configuration of the brain, taken together (Which is
Information) that can survive beyond death, provided they are saved
somehow. So If life/soul is DEFINED as it is the complete genome
sequence + the complete neuronal configuration of the brain, then
yes, souls exists and life can exist after death, just as a software
program exists independent of the physical computer and even after
the program has stopped running. While preservng the genome (i.e the
sequence information) is within current technology, saving the
complete neural connections is too formidable and beyond any
conceivable biotechnology. But soul defined this way does not go
anywhere, does not move, but stays as a potentia in the information
space. One can conceive of immortality in this definition, through
cloning. But while it may be possible to clone a human being
(over and over again), to overcome mortality, since the brain of
the cloned human can never be the same as the original human
(because neuronal configurations are determined by environemtnal
stimulus, besides genetic code, and environment will never be
exactly same in each rerun of a genome sequence), true
immortality is still not possible in the strict sense.
Some form of simulated resurrection of life (Virtual Immortality)
is however, possible to envisage within scientific framework, not
in the theological sense. This has been speculated by Physicist
Frank Tipler in his book "The Physics of Immortality",
based on some plausible assumptions in physics (like the universe has to
start decelerating at some point), although latest observations point
to an unlikely prospect for its coming true (scientifically), since
the universe seems to be accelerating for ever. Tipler's theory (Called
Omega Point Theory), has generated a cult of followers among the Transhumanists
and Extropians who call themselves Tiplerians.
Anyway, as mentioned before, the notion or the wish for Life after death is rooted
in the human refusal to accept death as the ultimate termination of
their identity. This fear of death and urge for immortality results
from Self-Consciousness, a necessary attribute of human
consciousness which makes us distinct from other species, who
only possess primitive consciousness with only primary instincts
of propagation, and avoiding dangers so as to successfully pass
their genes to next generation. A "conscious" anxiety due to
awareness of death, is a consequence of the growth of the
neocortex area in human brain, which is not present in other
mammmals. It is this Neocortex that has given rise to the
intriguing consistency loop that is a thing of wonder to all
scientists and philosophers :
Physical laws -> matter -> Life ->Consciousness -> Physical Laws.
Now some historical perspective on the quest for the answer to
the profound questions on life. The complete answer to the
questions on life has not and will not be answered in one
sweeping breakthrough or by one human in a finite time. The
fundamental fact is that the answer lies in an incremental,
cumulative approach to THE truth rather than a complete grasp
of it. We can get closer and closer to the truth. A lot has
been learned already. Very few of us laymen actually
are aware of the rapid increase in understanding that has been
going on. We only get a jolt when a flash of news are thrown at
us, for example, cloning of the sheep Dolly, the completion of
the human genome project, genetic engineering to increase
longevity by tweaking telomeres in chromosomes, etc. It must be
understood that saying that Life is the miraculous work of a
Divine creator does not "explain" life, it only puts a closure
to the quest for the answer and allows human to go about mundane
pursuits so as not to be distressed by the failure to understand
it. It is a common human instinct to put a closure to any
unresolved questions due to a feelin of uneasiness to living with
mysteries and unanswered questions. A scientific inquiry goes
against this instinct to jump into a premature closure and strives
to go deeper for further insights, incremental advance being the
goal, not a closure necessarily. A genuine understanding involves
a scientific study spanning across a host of disciplines. Every
day a new insight is being added to the knowledge base and
getting us incrementally closer to the final understanding.
Quantum jumps of insight do occur in history. For example
Darwin's Theory of Evolution, Mendel's theory of heredity and
the discovery around 1903 that chromososmes in the cell
are the containers of the Mendel's genetic unit or "gene",
culminating most importantly in the legendary discovery of DNA
structure in 1953 and deciphering of the genetic code in 1961. The
experiments of Urey and Miller showed how chemical and physical
process can create the ingredients of life if not life itself
(as yet). These are facts of life that are universal and
crosses all religious boundaries, unlike religious "explanations"
of life. Although Darwin explained beautifully how life evolved
from simple to the complex but only vaguely mentioned about a
possible mechanism of the origin of life itself (The primitive
pond). The first scientific attempt to understand the origin of
Life was by the Russian scientist Oparin in his 1929 classic
"The Origin of Life". He extended the Darwinian theory of
evolution backward in time to explain how simple organic and
inorganic materials might have combined into complex organic
compounds and how the latter might have formed the primordial
organism. The first attempt to understand life in a more
fundamental way was by the nobel laureate physicist none other
than the founder of quantum physics Erwin Schroedinger in his
epoch making book "What is Life? The Physical Aspect of the
Living Cell With Mind and Matter written more than fifty years
ago. He anticipated DNA and genetic code in that book even before
its discovery. He called it some kind of aperiodic crystal, carrying
hereditary information through some "codescript". Actually
Schrodinger's idea itself was based on that of another brilliant Physicist
turned biologist Max Delbruck, long before he received the Noble Prize
in medicine in 1969. Although now dated, the book was a mark of amazing
insight for its time. This book was the inspiration for all later
generation biologists and physicists interested in life's mystery,
like Watson and Crick who materialized their inspiration into
discovering the structire of DNA, Schrodinger's aperiodic crystal,
although the fact that DNA carries the genetic information itself
was dicovered by Canadian biologist Oswald Avery
in 1944. About half a century later another physicist from Princeton,
Freeman Dyson improved upon Schrodinger's idea and wrote the book
"Origins of Life". His ideas have been based on much more
insights gained in Biology and Physics since Schrodinger and
others. There has been a continued increase in our understanding
of life and its origins by scientists all around the world since
the milestone discovery of 1953. The next milestone was the
discovery of the genetic code that the DNA of all life forms
execute, first cracked by Nirenberg and completed by Har Govind Khorana
for which they both received the Nobel Prize in 1968. One of the most
creative of the scientists in the quest for the origin of life was the
Sri Lankan born American chemist/biologist
Ponnamperuma, who was the director of the laboratory of the chemical
evolution of life at the University of Maryland until his premature
death in 1995, and also the founder of the Third World Foundation,
an organization dedicated to the promotion of scientific minds of
the third world countries.. He along with Carl Sagan and Ruth
Martiner was able to produce ATP, one of the fundamental
building block of DNA, and thus of life. His insights into the
chemical nature of life's evolution signifies a quantum jump
from the days of Schroedinger and Oparin. Ponnamperuma said if
God exists then he must be a organic chemist. He called HCN
molecule "GOD molecule" because the intriguing way this molecule
gives rise to more complex molecules of life. A nice article on
the origin of life with some description of Ponnamperuma's work,
as well as more discussion on the origin of life
can be found at the site: http://www.rit.edu/~flwstv/biology.
html. Another pioneer in life research is Nobel Laureate Eigen and chemist
Orgel.
Eigen was able to induce (chemically) RNA molecules to replicate
in the lab. This is very close to producing a virus. Viruses are in
between living and non-living. Two more pioneers that should be
mentioned are Stuart Kauffman (A Biochemist) and Nobel Laureate
Ilya Prigogine (A physical chemist, whose name was mentioned
earlier) both of whom have shown how order can spring out of
chaos.
A caveat must be issued that it is never implied that Physics is
complete and all that can be known is known already. There will
certainly be insights gained in Physics and the laws of complexity,
in future and current concepts and laws may be revised or subsumed
under a more comprehensive scheme of laws (Theory of Everything).
But it will not at least invalidate what is certainly known and
tested today. Although human may not know the "?", they can still
spend their lifetime learning and discovering the natural laws that
exist and understand how it (Natural Laws) works and give rise to the
marvelous phenomena of evolution, formation of stars, galaxies,
snowflakes etc and try to understand life in an incremental way.
If there at all one has to find any meaning of this finite life
then the best candidate for meaning is the search to find the
answers to how life has evolved and will evolve. This is the
best use humans can make of their "gift" of consciousness, a
gift since it was after all notrequired by evolution for
survival, but came as a contingent by product of evolution. If
one has to speak of teleology then I think it is best to say we
have acquired consciousness so that we can explain how
consciousness came about (The self consistency loop). Many
top physicists, biologists, chemists (some Nobel laureates)
are in the forefront of the research into the origin and
evolution of life. Now they are being joined in this search by
computer scientists (specially artificial life/intelligence
people who view life as a software running on the hardware of
human body. Some even believe that one day a fully conscious
machine can be built!). We are witnessing an amazing synthesis
of human knowledge and insights in the dawn of 21st century.
Gone are the days when arm chair philosophers were idly talking
about their pet theories of life, consciousness etc. Without the
new language of genes, DNAs, entropy, Second Law, autocatalysis,
autopoiesis any talk of life would now sound like childish
babble, trapped in words going in circles, which can never add
any new insight, only categorize already known observations.
It would require a super philosopher today (There are a handful,
Paul Davies, Daniel Dennett to name a couple) well versed in all
these disciplines to pool together all these separate insights
into a coherent story of life. Each insight or a specialist in
that insight is but a link in a long chain. Individually they
may not capture the whole truth, but half truths, but the links
of half truths joined together may add up to the whole truth, or
at least the best approximation to it. This is a sort of emergent
law of truths. Individual pieces of truth all combining to yield
a profound truth that is not visisble in any of those individual
half truths.
Thousands of pages of results of scientific research into
consciousness, mind, life are being published monthly in
journals of evolutionary biology, evolutionary psychology,
biomathematics, biophysics, molecular genetics, artificial
intelligence, quantum consciousness etc. The best approximations
to date of the truth of life are distributed among these
separate database of knowledge that is continuously expanding.

The Evolutionary Origin of Moral Instincts
In two of my other articles I have dwelt on two aspects of
morality viz (1) The question of whether morality is defined
by religion and (2) If morality is purely subjective. I
wish to supplement the above two essays with a discussion on
the evolutionary basis of moral instincts, which I had alluded
to in those earlier essays but did not discuss it greater detail.
"There is a popular fallacy that a further source of values
for humans is an emergent property of culture. (Do not be
deceived by the word "emergent": it just means things are
complex and no one knows what is going on.) These values are
supposed to act over and above the values derived from our
genetic evolution, largely replacing them. This idea cannot
be justified. It may be regarded as one more example of our
vanity, in trying to believe that we are different from the
beasts in kind, not only in degree. We can understand how
value information could be programmed into our brains by
natural selection, but how could further values be invented
by information which we pass from one brain to another? Of
course we culturally transmit our values to each other, but
these values originate in the brains, not in the transmission
process."
So moral instinct (which also assigns values, i.e the "ought"
to thoughts, emotions and actions,) itself is rooted in the laws
of nature (Physics) via the working of the brain. Morality is
latent in the laws of nature. It finds expression through the
process of evolution. It seems almost common sensical/logical
that if human brain and thus human mind is a product of
evolution and subject to the laws of nature, then moral
instinct, which is a product of human mind (over generations)
must also be the product of evolution and thus ultimately the
laws of Physics. Culture is the proximate cause, but the laws
of physics the ultimate cause.
In the words of sociobiologist Edward O.Wilson : "ought is the
product of a material process. The solution points the way to
an objective grasp of the origin of ethics" (From his paper
"The Biological Basis of Morality")
How does evolution give rise to moral instinct? Evolutionary
psychology provides the plausible scenario. Again in his paper
"The Biological Basis of Morality" Edward O. Wilson illustrates
it this way:
"Suppose that human propensities to cooperate or defect are
heritable: some people are innately more cooperative, others
less so. In this respect moral aptitude would simply be like
almost all other mental traits studied to date. Among traits
with documented heritability, those closest to moral aptitude
are empathy with the distress of others and certain processes
of attachment between infants and their caregivers. To the
hereditability of moral aptitude add the abundant evidence of
history that cooperative individuals generally survive longer
and leave more offspring. Following that reasoning, in the
course of evolutionary history genes predisposing people
toward cooperative behavior would have come to predominate in
the human population as a whole.
Such a process repeated through thousands of generations
inevitably gave rise to moral sentiments. With the exception
of psychopaths (if any truly exist), every person vividly
experiences these instincts variously as conscience, self-
respect, remorse, empathy, shame, humility, and moral outrage.
They bias cultural evolution toward the conventions that
express the universal moral codes of honor, patriotism,
altruism, justice, compassion, mercy, and redemption."
More insight into the evolution of morality is provided by Game
Theory. A classic example being the Prisoner's Dilemma. Let us
describe this dilemma concisely:
Among the above only (3) and (4) are evolutionarily adaptive.
But to ensure that (3) and (4) can be true evolution, being
lazy enables brain for all of the four possibilities. (1) and
(2) are like the spandrel of an arch, collateral damage as in
the carpet bombing. Also among the traits originating from (1)
and (2) only those survive that are evolutionarily neutral (i.e
neither clearly adaptive nor clearly anti-adaptive).
"The new sciences of complexity and the perspectives on the
world offered by computer modelling may teach us things that
we did not realize about the values we hold. Science cannot
resolve moral conflicts, but it can help to more accurately
frame the debates about those conflicts. Take for example,
the act of lying. We hold the telling of truths as a value;
we are not supposed to lie. Yet if everyone told the truth
all the time so that one could have complete trust in what
one is told, then the advantage that would accrue to a
single liar in society would be immense. This is not a
stable social situation. On the other hand, in a society of
individuals in which everyone lied all the time, society
would be unworkable. The equlibrium state seems to be the
one in which people tell the truth most of the time but
occasionally lie, which is how the world really seems to be.
In a sense, then, it is the liars among (and within) us that
keep us both honest and on our guard. This kind of
scientific analysis of lying can help us understand why we
do it."
Just as evolution does not favour that all be truthful, it also
does not favour all be liars. In favours some liars among a
majority of truthful. Game theory confirms all this fundmanetal
fact of nature. Basically it confirms the old cliche that evil
is necessary so good can exist. But this time it is given a
mathematical justification. An utopian world of no evil is
theoreticlly imposiible in a species made of carbon based life
form as we know it.
Soul, Brain and The Laws of Physics
"I think there is a moral to this story, namely that it is more
important to have beauty in one's equations than to have them
fit experiment. .... If seems that if one is working from the
point of view of getting beauty in one's equations, and if one
has really a sound insight, one is on a sure line of progress.
If there is not complete agreement between the result of one's
work and experiment, one should not allow oneself to be too
discouraged, because the discrepancy may well be due to minor
features that are not properly taken into account and that will
get cleared up with further developments of the theory..."
The Nobel laureate Physicist Chandrasekhar who wrote a 650 page
mathematical tome "The Mathematical Theory of Black Holes" also
wrote a book called "Truth and Beauty" in which he emphasized
the role of sense of beauty behind the motivation of scientific
thinking. He says in the book that to him art, as seen from the
scientist's point of view, seems to be all the richer for it,
contrary to popular belief that rationality strips art of its
elemental passion. He also drew the parallel between the works of
Shakespeare, Beethoven, Shelley with the beauty inspired approach
of scientists for the search of the truth. So behind all the
profound discoveries lie the motivation from a sheer metaphysical
sense of beauty and mystery of the universe. Our own Sir Jagadish
Chandra Bose of Bangla also stressed this harmony between arts and
science in his essay "Poetry and Science" (Kobita o Biggan), and
much later, poet and mathematician Quazi Motahar Hussein in his
parallel essay titled "The Poet and the Scientist" (Kobi o
Boigganik). Let me mention yet some more examples.
"...we treat the Special and General Theories of Relativity as
important modernist works of art, the most important for our
purpose because they contain and express with the highest
intensity the values that for us define Modernism."
(click here
for details)
"That we are not nerds, but artists. That what we do and what
we are is exciting, creative and fun."
The scientific basis and connection of art has been explored by a
number of scientists and is also an ongoing pursuit of many
contemporary scientists and philosophers. Many have discovered
some systematic mathematical patterns and structures behind
patterns or objects commonly identified with beauty. This has
given rise to a cross-disciplinary field of "Computational
Aesthetics". One of the early pioneer in computational aesthetics
was the great American mathematician and former president of the
American Mathematical Society (1924-26), George David Birkhoff,
known to physics students for his famous ergodic theorem. He
tried to assign some objectivity to beauty with such notions as
order, complexity and beauty coefficient (or aesthetic measure)
in the late 20's and 30's. He wrote a paper "Mathematical Theory
of Aesthetics and its applications to Poetry and Music",in the
Rice Institute Pamphlet, 1932, 189-342. he followed up with a
lecture tour explainiung his research. On the basis of his objective
notions he did some calculations to indeed show why snowflakes,
flowers etc are more beautiful than some other not so beautiful
objects. Birkhoff has also worked out specific versions of his
formula for the auditory dimension of poetry, and for melodies.
Later a group of literary theorists in Germany in the fifties,
headed by Max Bense developed the theory of information esthetics
-- a Birkhoff-like model of beauty judgments, formulated in terms
of Claude Shannon' s information theory. Further developments in
informational aesthetics was made in the late sixties by the
psychologist Emmanuel Leeuwenberg in Nijmegen. I am just
mentioning the works of these scientists. Their work involves
elaborate detail and which I cannot do any justice to in this
sketchy overview, nor am I qualified to do so. Readers should
consult appropriate literature in interested in pursuing further.
The Implications of Evolution
These same laws of physics instigate the development of
life, including complex creatures such as humans, at least under
favorable circumstances. (p-191)
"We now know that the laws of Physics ultimately determine
the behavior of chemical reaction and biological processes."
(p-192)
The consummate example of emergent behavior is life itself. In
simple reactions, biochemical molecules behave according to known
chemical pathways. When these molecular systems become sufficiently
complex, they act in novel ways. After this emergent level of
complexity reaches a critical threshold, the system becomes alive.
But the details of this transition remain shrouded in mystery. In
spite of this gaping hole in our understanding, however, biological
processes are driven by the same laws of physics that describe
stars and planets. The concept of vitalism -- the idea that
biological laws are independent of physical laws -- has been
safely relegated to the trash heap of outdated ideas. (p-193)
From Back Flap:
With so much talk about the frontier of biology these days, I
welcome the occasional reminder that the laws of physics control
the formation and evolution of life.
- Neil DeGrasse Tyson, Director, Hayden Planetarium
As a final example renowned biologist Earnst Mayr wrote in his book
"The growth of Biological Thoughts ('82): "Every biologist is fully
aware of the fact that molecular biology has demonstrated decisively
that all processes in living organisms can be explained in terms of
Physics and chemistry"(As cited in Weinberg,"Facing Up", p-19)
Evolution and Love
All our desires, passions etc, reflect inanimate tendencies already
implicit before life in the second law of Thermodynamics. Sexual
reproducers, living beings making more of them - selves, achieve not
only biological ends, but those of physics as well. p-46:
Technology, civilization cannot distance us from our
animal selves, but instead accentuate them. Trendy glasses,
epaulets etc are similar to tailbones of peacocks (p-170)
Deception appears to be necessary and therefore built into our
sexual biology
Again not to confuse IS with OUGHT. What nature prescribes, nature also
proscribes (via conflicting urges). It is this conflicting forces (or
instincts) within humans that act as the stabilizing force in evolution.
"Men's relatively large testes are a solid evidence that women
in evolutionary history were promiscuous"
"From a darwinian perspective, however, there were advantages to
serial monogamy millenia ago". From a darwinian perspective,
having children with more than one partners often make genetic
sense" (p-159).
Male essence(sweat) helps maintain regularity of female menstrual
cycle. Hence females's (unconscious) attraction to male smell may be
evolutionarily caused. The reason males now use deodorants and women
prefer them may be culturally conditioned by the aggressive selling/
advertizing of producers and making perspiration is equaled to
uncleanliness.
Joann Rodgers also mentions in her book on page-251 that women prefer
men with the most dissimilar MHC genes (as observed through sniffing
T-shirts soaked in armpit). Needless to say that these preferences are
instinctually hardwired by evolution, not by conscious choice.
