For administrative and fi nancial support for the conference, we thank the philosophy depart- ments at Washington State University (David Shier, Chair) and the Univer- sity of Idaho (Douglas Lind, Chair), the College of Liberal Arts at Washington State University (Erich Lear, Dean), the College of Letters, Arts & Social Sciences (Joe Zeller, Dean) and the Provost’s Offi ce at the University of Idaho, the research offi ces at both universities, and the departmental administrative managers, DeeDee Torgeson and Diane Elli- son. We are also grateful for a grant from the Idaho Humanities Council, a state-based affi liate of the National Endowment for the Humanities, to help fund the Public Forum. Those who presented papers at INPC 2005 were encouraged to submit their work for possible inclusion in this volume, and, after a process of peer evaluation, only a few were selected. We regret that we had to turn down numerous quality essays. For help with the selection process and other matters, we thank William Beardsley, Ben Bradley, Andrei Buckareff, Ben Caplan, Larry Colter, Barry Dainton, Bruce Glymour, Gary Hardcastle, Katherine Hawley, Mark Heller, Paul Hovda, Charlie Huenemann, Simon Keller, Ann Levey, Marc Moffett, Mark Moyer, Joe Salerno, Steve Savitt, Christopher Shields, Russell Wahl, Lisa Warenski, Ryan Wasserman, Brian Weatherson, and Ron Wilburn. Finally, our thanks to Delphine Keim Campbell, Rebecca O’Rourke, and Lorinda Knight for continued support and understanding! Introduction: Framing the Problems of Time and Identity Matthew H. Slater Concepts Familiar yet Perplexing Many philosophical concepts are diffi cult. Some, however, are doubly con- founding in their apparent f amiliarity . The concepts of t ime and i dentity may top this list. The fourth-century philosopher, Augustine of Hippo, expressed his exasperation with time this way: For what is time? Who can easily and briefl y explain it? Who can even comprehend it in thought or put the answer into words? Yet is it not true that in conversation we refer to nothing more familiarly or knowingly than time? And surely we under- stand it when we speak of it; we understand it also when we hear another speak of it. What, then, is time? If no one asks me, I know what it is. If I wish to explain it to him who asks me, I do not know. (C onfessions , 11, XIV, 17) Time is an intricate and deeply embedded part of our experience. Indeed, it would seem that the passage of time is a prerequisite for having any experi- ences at all. But a number of recalcitrant questions about time remain: Is time real? Does time objectively fl ow? Do past and future moments exist just as present moments do, or is the present in some way special? The concept of identity also seems at once philosophically unproblem- atic and frustratingly diffi cult. It is, as philosophers have long noted, that relation everything bears to itself and to no other thing .1 Of course, as Haw- thorne (2003 , 99) points out, this cannot be an analysis of identity—for ‘ itself ’ and ‘no other thing’ already presuppose an understanding of iden- tity. David Lewis likewise tempers his praise of identity’s simplicity: There is never any problem about what makes something identical to itself; noth- ing can ever fail to be. And there is never any problem about what makes two things identical; two things never can be identical. There might be a problem about how to defi ne identity to someone suffi ciently lacking in conceptual resources—we note that it won’t suffi ce to teach him certain rules of inference—but since such
