The origins of this book probably go back to Gordon Allport''s seminar in social psychology at Harvard during the late 1940s and to the invitation from Gardner Lindzey, some years later, to contribute a section on "Sympathy and Empathy" to the International Encyclopedia of the Social Sciences (1968). Since those early beginnings, the book has been "in the process of becoming. " During that time I have benefited greatly from the knowledge and assistance of many colleagues, especially the following, who read and commented upon portions of the manuscript: Raymond Gastil, the late Joseph Katz, David McClelland, Jitendra Mohanty, Paul Mussen, Richard Solomon, and Bernard Weiner. To Kenneth Merrill for a close reading of the Hume material and to M. Brewster Smith for a careful reading of and suggestions on Chapters 7 and 8, I am especially indebted. Beverly Joyce withstood constant interruptions to provide much-needed library assistance, and Vivian Wheeler gave generously of her excellent editorial experience and knowledge. A fellowship at the Battelle Research Center in Seattle and an appointment as a visiting scholar at Harvard were of incalculable help, providing opportunity, stimulation, and freedom from teaching responsibilities. To all of the above I am deeply indebted. Just a few words about the organization of this book.
