It is in Meditation II that Descartes recounts his certainty regarding his existence. He claims that he exists because he is capable of thinking; “I think, therefore I am.” Even though he believes that all his senses are subject to analysis, he knows with certainty that he thinks. This brings us to the concept of separation between mind and body. Meditation II is Descartes' assertion that the mind and body are separate from each other. Further in Meditation VI, Descartes evaluates the existence of material objects, far from the existence of self and the existence of God. He admits to believing that material objects can exist since they are “objects of pure mathematics”. He recognizes that God is capable of creating whatever he is capable of perceiving. Additionally, Descartes recognizes that the imagination produces evidence to support the perceived existence of external elements.
