Motivational musings based on the question."If a tree falls in the woods and no one hears it does it make a sound?"
How old is this question, anyway? My current conjecture is that it is Aristotelian logic in expression. Therefore, thousands of years old. My first Aristotelian cunundrum went thus, "If a hippo is large and mrs jones is large is mrs jones a hippo?"
On second thought Aristotle had nothing to do with this tree thing...and I am filled with enough mental fertilizer to constipate a hippo.
