On the featureless Tunisian desert, a long-legged, fast-moving ant leaves the protection of the humid nest on a foraging expedition. It moves across the desert in tortuous loops, running first this way, then that, but gradually pro gressing ever farther away from the life-sustaining humidity of the nest. Finally it finds the carcass of a scorpion, uses its strong pincers to gouge out a chunk nearly its own size, then turns to orient within one or two degrees of the straight line between itself and the nest entrance, a one-millimeter-wide hole, forty meters distant. It runs a straight line for forty-three meters, holding its course by maintaining its angle to the sun. Three meters past the point at which it should have encountered the entrance, the ant abruptly breaks into the search pattern by which it eventually locates it. A witness to this home ward journey finds it hard to resist the inference that the ant on its search for food possessed at every moment a representation of its position relative to the entrance to the nest, a spatial representation that enabled it to compute the solar angle and the distance of the homeward journey from wherever it hap pened to encounter food.

Popkin in the first course I ever took in philosophy. Popkin later directed the dissertation I wrote on the scourge of the likeness problem, Simon Foucher. In between, I was instructed concerning the importance of ontology by Gustav Bergmann. And my first essay on the subject was an M.A. thesis directed by Robert G. Turnbull, all of this taking place at the University of Iowa in the early 1950s. Over the years, I have had many discussions about the matter with them, and with Edwin Allaire, Harry Bracken, Claude Chabert, Phillip Cummins, Alan Gabbey, Reinhardt Grossman, Donald Livingston, Jerome Schiller, Sara Shute, Kathleen Squadrito, Henry Van Leeuwen, and Thomas Vernon. More recently, Robert Cummins brought to my attention the ubiquity of resemblance in contemporary theories of representation. Mark Rollins provided an excellent orientation to recent work. Steven Nadler ar gued with me about Arnauld and Malebranche, and suggested numerous re visions, some of which I have made. Jose R. Maia-Neto made astute comments on early drafts. William Lycan and Ruth Millikan, fine-grained philosophers of high accomplishment, responded heroically to my demands for comments on this coarse-grained commentary. And Justin Leiber combed the manu script for me. At Washington University, I appreciate the enlightened policies of Martin Israel, Dean of Arts and Sciences; Roger Gibson, Chair of the De partment of Philosophy; and Patty Jo Watson, who provided me with time for research and writing. I thank them all. I also thank the editors of the Ameri can Philosophical Quarterly in which a shortened version of Chapter 7, "Hav ing Ideas," appeared (Vol. 31, 1944, pp. 185-197). The first draft was completed during 1991-1992 while I was a Fellow at the Center for Advanced Study in the Behavioral Sciences, Stanford, Califor nia, with financial support provided by the Mellon Foundation, for which I am grateful. I have always benefited from the encouragement of Director Emeritus Gardner Lindzey, to whom I present this book in the guise of a third-quarter report. Finally, I thank Director Philip Converse and Associate Director Robert Scott
