1. Descartes was convinced some evil demon had committed itself to deceiving him so everything he thought was false. Descartes provided a method of doubt to defeat skepticism. First, Descartes noted that the testimony of the sense with respect to any particular judgment about the external world may turn out to be mistaken. (Med I) things are no always just as they seem at first glance to be. Secondly, Descartes raised more systematic method for doubting the legitimacy of all sensory perception. (Med I) it is possible to doubt that any physical thing really exists, that there is an external world at all. Finally, Descartes raises doubt by considering a radical theory, a deceiving God. (Med I) the persuasion that these do not exist otherwise …show more content…

(Med III) By the name of God, I understand a substance infinite, all-knowing, all-powerful, and by which I myself, and ever other thing that exists, if any such there be, were created. And thus it is absolutely necessary to conclude, from all that I have before said, that God exists.
Descartes offered a backup to the argument and offered the thought that could he exist supposing there were no God. Descartes asserts he knows he exists, and since he is not perfect in every way, I cannot have caused myself. Therefore, something else must have caused his existence and no matter what that matter is to have caused the existence, the question remains what caused the existence. The chain of causes must end eventually and that is the perfect, self caused of being, God.
3. In the sixth mediation, Descartes attempted to discard the dream problem by proving there is a material world and that bodies do exist. His argument derives from the uncertainty that divinely-bestowed human faculties of cognition must always be regarded as adequately designed for some specific purpose. Since three of our faculties involve representation of physical things, the argument proceeds in three distinct stages. (Med.
