PHIL-180 Philosophy and Star Trek

I. Is time travel possible? Could we go back and kill our grandmothers? What is the nature of time? 
II. Could reality be radically different from what "we" (I?) think? Could we be brains in vats? 
III. What is the relation between a person's mind and his functioning brain--are they separate substances or identical? Can persons survive death? Can computers think? Is Data a person? 
IV. What is a person? When do we have one person, and when do we have two (think of the episodes where people "split" or are "fused")? 
V. Do people have free will, or are they determined by the laws of nature to do exactly what they wind up doing, while believing they have free will? Or both? What is free will?
