René Descartes, a famed mathematician and philosopher, enacted a thought project where he applied radical doubt to everything in existence, including himself. He wrote a treatise about the experience, called “Meditations on First Philosophy”, of which there are six parts. After first establishing his own existence as a “thinking thing,” Descartes wonders about the existence of God (153). Descartes then follows to prove, through a series of arguments, that God exists, and that the existence of God merits the existence of a material world. Early in the Meditations, Descartes inquires as to whether God might be an ‘evil genius’ of sorts, manipulating his thoughts and perceptions, or even falsely planting them, and assumes that this is the case saying that God is …show more content…

Or, in relation to Descartes and God, since Descartes considers himself to exist, then that which created him must be at least as real as he, if not more so. Descartes establishes the assumption that God created him, and by this principle God must exist. He also considers the existence of God to be necessary, as he would not have formed ideas of something infinite and omnipotent based upon knowing only himself, since, by nature, he is finite and limited in knowledge. Descartes employs an ontological argument to further prove that God exists. Ontological arguments are arguments where two things are necessarily connected to one another if the second cannot be thought of without the first also necessarily being thought of. In his argument, Descartes says that if there is a god, then he would have all possible perfections. If existence is a perfection, then God must exist, since existence is included as a perfection that he
