Descartes' Meditations

Descartes' meditations are created in pursuit of certainty, or true knowledge. He cannot assume that what he has learned is necessarily true, because he is unsure of the accuracy of its initial source. In order to purge himself of all information that is possibly wrong, he subjects his knowledge to methodic doubt. This results in a (theoretical) doubt of everything he knows. Anything, he reasons, that can sustain such serious doubt must be unquestionable truth, and knowledge can then be built from that base. Eventually, Descartes doubts everything. But by doubting, he must exist, hence his "Cogito ergo sum". It is from this thought that Descartes is able to determine God exists and create his first …show more content…

He does not have the capability of thinking of an infinite substance or a perfect substance, such as God, because he has lesser reality than these ideas and cannot be the cause of them. The only way these ideas could exist is if they were created by something of equal (greater being impossible, as infinite perfection cannot have a superior) reality. Because God is the only infinite Descartes can recognize at this state, it must be God that planted the idea in his mind. Descartes' first argument for the existence of God can be summarized as follows:
1)I have an idea of a perfect being
2)There are two forms existence- contingent and necessary
3)Necessary existence has greater reality than contingent
4)A perfect being must have necessary existence
5)A perfect being must exist, if it has necessary existence
6)Therefore, God exists (Notes) This allows Descartes to begin to gain true knowledge, because his perfect being exists and would not allow him to be deceived all the time because perfection does not allow for that behavior. In the Fifth Mediation, Descartes purports his ontological argument for the existence of God. It is simpler than his first and based on God's essence. For anything else that exists, the essence of that thing only implies it's existence. For God, however, essence
