Descartes: I Think, Therefore I Am

Through skepticism and doubt Descartes raised a simple yet complex question, what can I be certain of if I doubt everything? Struck by all of the falsehoods he had come to believe, Descartes set out to determine through reason what was certain and able to exist beyond doubt. In order for his habitual opinions and false knowledge to not interfere with his ability to perceive things as they truly were, Descartes doubted everything. In terms of the physical body, our senses tell us that there are external ligaments and matter that come together to produce a body. However, when we are skeptical and doubt all previous knowledge, we are then deceived by our senses and the physical body cannot be proven to exist. Even while doubting the existence of the physical body, Descartes was still able to project skepticism and have thoughts of doubt. There must have been a thinking thing thinking those doubts.

There is no way of concluding that there is a self or even person if perceptions and feelings are unobservable with no way of knowing if they remain consistent through time. The thoughts of doubt that led Descartes to form the concept of self through, “I think, therefore I am,” cannot provide evidence of a self.
