You may have discussed the problem of personal identity in some other philosophy class. If so you might find it interesting to test some of the theories of the nature of mental states by applying them to that problem and seeing whether the answers they give are plausible. For instance, in his science fiction novel Beyond Rejection , the philosopher Justin Leiber envisions a world in which people periodically have all their memories, beliefs, wishes, etc. If they die unexpectedly and a spare body can be found, their memories etc. are transferred into the brain of this body. Suppose you die unexpectedly, and this procedure is performed.
Someone wakes up in the spare body with all the beliefs, memories, etc.
On the assumption that it is you if and only if it has the same mind as you, the different theories we have considered about the nature of the mind will lead to different answers. You could write on the possibility of machine intelligence. Other essential reading includes the criticisms of Searle and Dreyfus. All three are collected in John Haugeland's volume Mind Design and the updated version Mind Design II . Another source of a lot of good stuff, including Turing and Searle, is Margaret Boden, ed., The Philosophy of Artificial Intelligence .
