His proof begins with the understanding that for a thought to contain any amount of objective reality, it must be derived from a cause that contains at least as much formal reality as it there is objectivity. reality in the original thought. He continues this point with the fact that there must be a cause which formally contains all the reality present objectively in the idea. Basically, for a thought, with a certain amount of representational reality, to exist in an individual, it must have been drawn from a source with at least as much representational reality as there is formal reality in that source. Descartes then explains that if the representational reality of an idea cannot be derived from within, then it must come from something else. He goes on to explain that the idea that God has the properties of being eternal, omnipotent and infinite could not come from any individual, because these are properties of an infinite substance and beyond our ability to postulate. Thus, he states that they must come from God and therefore God exists. The final stages of his proof can be drawn
