(CHOOSE ONE) 1. In the Meditations, Descartes believes that the one belief that he knows to be indubitably true is that “I exist” and that “I am a thinking thing.” How does Descartes argue for this indubitability? Do you agree or disagree with him? 2. In the Enquiry concerning Human Understanding, Hume argues that reasoning about matters of fact—essentially, causality—has no rational foundation. Why does he think this? Do you agree or disagree with him? 3. In the Prolegomena to any Future Metaphysics, Kant claims that while Hume raised the question of the possibility of metaphysics, he was unable to provide the right answer to this question. What, according to Kant, was Hume’s error? Is Kant correct that Hume committed this error? Papers should be at least 1500 words long (around 6 pages), but they can be more. They will be graded on the basis of (1) clarity, i.e., accurately understanding and presenting the texts under consideration; (2) organization, i.e., presenting a clear, coherent, argument that justifies your main claim; and (3) originality, i.e., developing your own original idea.
