This paper is, in effect, a reply to Richmond Campbell's (1988a), first presented at Dalhousie University in 1986. I am grateful to Campbell for pointing me at the relevant literature, for his searching criticism, and for his editorial comments. My thanks are also due to Neera Badhwar, Robert Bright, Douglas Butler, Robert Martin, Geoffrey Sayre-McCord, Terrance Tomkow, Kadri Vihvelin, and Sheldon Wein, and to an anonymous referee who requested some important clarifications in the exposition of Gauthier's program. I am especially indebted to Julia Colterjohn, whose role as foil is evident throughout, and who read earlier versions with undaunted incredulity. My thanks to the Killam Trust of Dalhousie University, whose post-doctoral fellowship support I enjoyed during the spring and summer of 1986.
