In the Third Meditation, entitled “Of God: That He Exists”, Rene Descartes presents an argument in favor of the existence of God. Meditation III talks about what is real and how to justify it. Descartes admits that he doubts bodily things but is absolutely sure that he exists and perceives this fact clearly and distinctly. As a confirmation: I am a thinking (conscious) thing, that is, a being who doubts, affirms, denies, knows few objects and ignores many, - [who loves, hates], wants, rejects, who imagines alike, and perceives. . . (Descartes p 66) However, it could not be certain unless every clear and distinct perception could be true. From this he concludes that everything that is perceived clearly and distinctly must be true. Therefore, he is not only proving that God exists, but also proving his existence. During his youth, Descartes thought he was sure that all the things he believed were true, but now he doubts it. For example, “two and three added together make five” (Descartes 67), which he finds clear and distinct. However, he is not sure because he thinks God might be deceiving him. He says: For if I later thought that these things should be doubted, it was for no other reason than because it occurred to me that a God might perhaps have given me such a nature as to deceive me, even concerning things. which seemed more evidently true to me. (Descartes 67) Since he assumes that there is a malevolent God who he thinks is deceiving him, Descartes must therefore make sure and look for evidence that he is not completely deceived. So, this pushes him to prove that God exists and is not a deceiver.
