This book presents reports on the uses of sociobiology and general evolutionary theory by members of diverse disciplines: psychiatry, law, management theory, anthropology, economics, primatology, history, political science, ethical philosophy, cognitive psychology, epistemology, socioecology of religion, studies of conflict, Marxist thought, aesthetics, sociology, linguistics, and psychology. The purpose of the book is threefold -- to acknowledge the remarkably wide influence of a central idea; to demonstrate that the research of human sociobiology takes place in disparate fields; and to introduce the major principles of sociobiology. There are many surprises to be found in these pages, not least the psychiatrist's new look at anxiety, the management theorist's explanation for the success of Japanese firms, the Soviet philosopher's report on sociobiology in the U. S. S. R., the explanation given for the keeping of harems in ancient kingdoms, and the economist's view as to why people care if a bargain price is really a fair price -- all cast in sociobiological terms.
