I explore David Lewis's view on how persons persist through time. Persons are subject to the problem of temporary intrinsic properties-properties that someone has at one time and not at another time. How can one person at one time be identical with some a person at another time when they have differing properties? (E.g., David sitting, and then later, David standing.) Lewis says that is a mistaken question, and persons are actually collections of person stages. Lewis argues that it is one person stage that sits, and a different person stage that stands later.
