I was feeling like Amber, that Descartes overly logical mathematical mind gets in the way. he is analyzing in black and white and I don't feel the world is that way.He doesn't seem to take into consideration the psyche,and how things can happen in your life that are way beyond coincidence, especially if you are open and in tune to these things coming along in your day to day existence, you can learn a lot from them. I do understand his questioning everything, although my first reaction is this guy was hitting the opium pipe and just tripping out big time.What about the feelings when you just know something deep inside,almost a physical gut reaction kind of feeling.
