The first single-volume work to capture Freud's ideas as scientist, humanist, physician, and philosopher. What to read from the vast output of Sigmund Freud has long been a puzzle. Freudian thought permeates virtually every aspect of twentieth-century life; to understand Freud is to explore not only his scientific papers—on the psycho-sexual theory of human development, his theory of the mind, and the basic techniques of psychoanalysis—but also his vivid writings on art, literature, religion, politics, and culture. The fifty-one texts in this volume range from Freud's dreams, to essays on sexuality, and on to his late writings, including Civilization and Its Discontents. Peter Gay, a leading scholar of Freud and his work, has carefully chosen these selections to provide a full portrait of Freud's thought.
