First Midterm Paper: Descartes’ Second Argument for the Existence of God As with almost all of Descartes inquiries the roots of his second argument for the existence of God begin with his desire to build a foundation of knowledge that he can clearly and distinctly perceive. At the beginning of the third meditation Descartes once again recollects the things that he knows with certainty. The problem arises when he attempts to clearly and distinctly understand truths of arithmetic and geometry. Descartes has enough evidence to believe these things, but one major doubt is still present; the possibility of God being a deceiver. Descartes worry is that all the knowledge that he possesses through intuition could potentially be false if God merely chooses to deceive him. So in order to have a clear and distinct perception of arithmetic truths (and other such intuitive truths) Descartes delves into the question of God’s existence (and whether this God could be a deceiver or not). After giving his first proof for the existence of God Descartes concludes by mentioning that this proof is not always self-evident. When he is absorbed in the world of sensory illusions it is not quite obvious to him that God’s existence can be derived from the idea of God. So to further cement God’s existence Descartes begins his second proof by posing the question of whether he could exist (a thinking thing that possesses the idea of an infinite and perfect god) if God itself did not exist.
