The University of Rochester's Department of Philosophy is sponsoring a colloquium by Theodore Sider, a professor of philosophy at Syracuse University. Sider will be speaking on "Time and Temporal Parts." In his talk, Sider will discuss several arguments supporting a view in metaphysics in which things persist through change by having temporal parts. The event will begin at 3:30 p.m., Friday, Jan. 28, in Room 2-110D in Dewey Hall on the River Campus. The departmental colloquium will include a discussion period, and will be followed by a reception in the Linguistics and Philosophy Lounge in 501 Lattimore Hall.

Sider's publications have contributed to several recent discussions in metaphysics, including such topics as supervenience, intrinsic properties, and four dimensionalism. Sider taught at the University of Rochester from 1992 until 1998, when he moved to his current position at Syracuse University. In 1998 Sider was honored as the University of Rochester's Professor of the Year. The award is given out each year by the Students' Association.

The event is free and open to the public.
