This collection of papers has its origin in a conference held at the
Uni- versity of Toronto in June of 1988. The theme of the conference was
Physicalism in Mathematics: Recent Work in the Philosophy of Math-
ematics. At the conference, papers were read by Geoffrey Hellman
(Minnesota), Yvon Gauthier (Montreal), Michael Hallett (McGill), Hartry
Field (USC), Bob Hale (Lancaster & St Andrew's), Alasdair Urquhart
(Toronto) and Penelope Maddy (Irvine). This volume supplements updated
versions of six of those papers with contributions by Jim Brown
(Toronto), John Bigelow (La Trobe), John Burgess (Princeton), Chandler
Davis (Toronto), David Papineau (Cambridge), Michael Resnik (North
Carolina at Chapel Hill), Peter Simons (Salzburg) and Crispin Wright (St
Andrews & Michigan). Together they provide a vivid, expansive snapshot
of the exciting work which is currently being carried out in philosophy
of mathematics. Generous financial support for the original conference
was provided by the Social Sciences & Humanities Research Council of
Canada, the British Council, and the Department of Philosophy together
with the Office of Internal Relations at the University of Toronto.
Additional support for the production of this volume was gratefully
received from the Social Sciences & Humanities Research Council of
Canada.
