Descartes Meditations Descartes' Cogito Ergo Sum(I am, I exist) argument is a complex one. In many ways, he constructs a convincing argument for the existence of the self, and for the process of the thinking being, the essence of that self. In this meditation on his philosophy, Descartes on numerous attempts tries to convince both the readers, as well as himself, of his theory that we must reject all of our present ideas and beliefs and start from nothing. He believes that the only thing that has any certainty at this point is his own existence as a thinking being? Everything else, which he has learned throughout his entire life and believed in, is to be thrown out because it is not known clearly and distinctly. Descartes method and theory on knowledge was well planned and carefully thought out. It is evident that he spent a great deal of time determining the principles that he would use as determinants for judging whether a specific idea was justified and true. In my opinion, there are some flaws contained in Descartes' argument. Among these flaws are Descartes apparent determination to prove his theory on his individual existence in the world and the existence of G-d to backup and prove himself and his theories. At the beginning of meditation two, Descartes is stuck in the middle of nothingness. He has nothing, nothing to believe in and everything around him he regards as false. This is because he cannot believe what he has learned and he is also unable to trust his senses due to the fact that they deceive him. He feels like he is drowning in a whirlpool and cannot reach the top and get out nor can he put his feet on the bottom and stand? Everything in the world at this point he has called into doubt, including himself. Everything that he has ever seen, learned or thought is now external from what he deems to be true and he is beginning his knowledge from non-existence. Descartes although is certain of one thing, nothing (but to be certain of nothing is still to be certain of something?).
