In this paper I argue three things: (1) that the interactionist view underlying Benacerraf's (1973) challenge to mathematical beliefs renders inexplicable the reliability of most of our beliefs in physics; (2) that examples from mathematical physics suggest that we should view reliability differently; and (3) that abstract mathematical considerations are indispensable to explanations of the reliability of our beliefs.
I am indebted to many for help with this paper: to Yvon Gauthier, Henri Lauener, and Ruth Marcus for criticisms of a distant relative at the World Congress in Philosophy, Brighton, England, 1988; to ACLS for a travel grant; to my colleagues, Mark Kaplan, John Koethe, Bob Schwartz, and Julius Sensat; to Jeff King; to an anonymous referee for comments on a related paper; and especially to Mark Wilson for many suggestions.
