Yes, this assignment is late. But that is not the point. At all. Rene Descartes was a philospher, my favorite in fact. Rene Descartes set out to determine the reality of things. He would do so by trying to prove they believe. For instance, to prove he was actually conscious he attempted to determine if he had free thought and if he was not being controlled by some controlling demon. He later tried to determine if things were real by expereince a change in them. I did the same thing with my bead. To prove the bead existed (loosely) I smashed it into a hammer, and saw it become smaller pieces.
