Persistence and Time 1

Issues about life and death seem intertwined with issues about persistence and time: we live as long as we persist through time, and our deaths seem to mark the limits of our persistence. Metaphysicians have thought deeply about the nature of time, and about what it is for things in general to persist though time. In this chapter I outline some metaphysical views about time, and about persistence, and discuss how they can help us clarify our thinking about life and death.
