Summary/Abstract: David Lewis set the agenda for philosophical theorizing about time travel fifty years ago with his landmark paper "The Paradoxes of Time Travel". In honor of that anniversary, I review some of the central themes of his paper and discuss a few of the ongoing debates inspired by that work. In particular, I address some worries that have been raised for Lewis's characterization of time travel, his treatment of backward causation, and his proposed solution to the grandfather paradox.
