Philosophy

The movie Inception is the best “question reality” movie since the Matrix (ultimately the Matrix is better, in my opinion), and it raises many fascinating questions having to do with the differences between the two primary states of consciousness available to humans today: waking and dreaming.

Coincidence, Randomness, and Meaning

by Seth on November 30, 2009

Maybe you’ve had this experience:  You are thinking about an acquaintance that you haven’t thought about in a long time and at that moment the phone rings.  ”What are the odds that it’s Jerry?” you think to yourself.  And when it IS Jerry on the other line it seems somehow magical, amazing, beyond mere chance.
