Epistemology and Logic

The subjects of Epistemology and Logic are considered by myself to be essential for a critical and open view of society and ourselves. So lets start with some bare-bones defintions of these two ideas.

To begin with...these ideas are often thought of as merely "philosophical" and therefore, rather esoteric. However, since I believe that difficult ideas still need to be dealt with if they are important ones, as I did in my classes, I will present them here straightforwardly and in "practical" terms. Why I feel this way will hopefully become clearer as I explain them.


Although there are varying definitions of this term, I will define it on two levels...a "formal" definition and then a "working" definition.

The Formal essence, a dictionary definition...would be:

The investigation of the...

1. origin,

2. nature,

3. methods...and

4. limits

of human knowing and knowledge.

As such epistemology is that branch of philosophy with investigates the conditions for knowing/creating knowledge.

The Working own working

The study of HOW we KNOW what we SAY we KNOW

As such I am interested primarily in #3 of the Formal definition...the methods (HOW) by which we come to know anything. Actually, I feel the other three areas are within the methods of knowing and would necessarily be touched upon by focusing on the methods.

Having defined epistemology this way, this leads to a consideration of:


In the broadest sense of the term, there is only one "method" by which knowing takes place...a LOGIC SYSTEM. So without refering to any particular logic system...nor any particular kind of "knowing"...I will again utilize "formal" and "working" defintions:

The Formal definition would be:

a SYSTEM of principles of reasoning utilized for inferring correctly and reliably in the process of knowing

As such this refers to an organized way of knowing that is applied to the raw phenomena of life

The Workingdefinition would be:

the method/mechanism/tools used to...

1. conceptualize,

2. name,

3. label,

4. describe...and

5. explain

reality (physical, mental, and social)

As such a logic system is a set of tools with which we "order" reality. These tools are not innate within us...but rather, are taught to us.

Effects of Logic System in Everyday Life

The following has been adapted from a Psychology textbook written by Zimbardo and Ruch...Psychology and Life, 9th Edition. Although not intended to be used in this way by these authors, I've felt since the first time I saw it that it reflected something important...and after a number of years of shuffling it from file to file, I finally realized that it represented the difference between the two major Logic Systems in least in the "western" world...Formal Logic and Dialectical Logic. I took the liberty of renaming it and utilizing it in my Introductory Sociology classes as a way for students to assess themselves...after hearing and studying my presentation of Epistemology and Logic (see link above).

I assign an Analysis Paper covering this table and the results have been very gratifying...students see the relevance of it to the lecture and handout materials as well as to how this seemingly esoteric material has relevance in their everyday lives.

The table lists ten (10) abilities or activities we all engage in...all the time. Each ability is then symbolized by the characteristics which roughly correspond to the Logic System primarily utilized in our thinking and behaving. While clear-cut placement of ourselves in one system or the other isn't always possible...many students realize they're a combination/synthesis of both...self-reflection upon these choices helps to highlight which logic system is which areas...and...where we might want to change how we approach and conceptualize our experiences.

So, I offer this material as a means of understanding ourselves a bit better. I make no claims for its definitive meaning...only that it points us in the direction of understanding why we think and do certain things in certain ways...that is, how the Logic System we use to name our world affects how we experience that very world.

Give it a try.
