In Meditation III Descartes offers an argument for Gods existence using as a premise that he (Descartes) has an idea of God. One might wonder whether such an argument would apply in the case of others of Descartes ideas. E.g. would Descartes think that his having an idea of the Evil Demon proves that the Evil Demon exists? This is the question you are to answer in your essay. And you are to explain and defend your answer. In the course of your essay you should address the following: why did Descartes think that his having an idea of God proves God exists? What according to Descartes is the source of his idea of God? How does the idea of the Evil Demon differ from the idea of God? What in keeping with Descartes position is or could be the source of his idea of the Evil Demon?
