Descartes and his theories

'I think therefore I am.' Man wills, refuses, perceives, understands, and denies many principles. As explained by Rene' Descartes, man is a thinking thing, a conscious being who truthfully exists because he is certain that it is so. All that man perceives is internally present and not external to him or his mind. The focal point of the third meditation that must be dealt with is: Can one perceive or confirm the existence of …

…is perceived in the mind as long as there are equal or superior properties in the mind. His rests his whole argument on the basis that one cannot fully grasp or fathom the existence of God logically. It is obvious that his perception is doubtful in the first place. There is a lot more material to be covered before I can honestly sever Descartes' whole argument, but this is my opinion on the third meditation.
