Metaphysics is concerned with fundamental questions about the nature of reality. This very partial introduction will focus on an interrelated set of questions concerning identity, persons, survival, and time. It will first explore identity and change of composition with respect to inanimate objects. It will then delve into the nature of persons and the possibility of their survival after physical death and in other conceivable scenarios. Since these initial topics touch at some points on the nature of time, it will take a brief foray into the possibility and conceptual complications of time travel before concluding with the possibility that the world in which we seem to be living is a computer simulation.
