What is an Emotion?, 2/e, draws together important selections from classical and contemporary theories and debates about emotion. Utilizing sources from a variety of subject areas including philosophy, psychology, and biology, editor Robert Solomon provides an illuminating look at the "affective" side of psychology and philosophy from the perspective of the world's great thinkers. Part One of the book features five classic readings from Aristotle, the Stoics, Descartes, Spinoza, and Hume. Part Two offers classic and contemporary theories from the social sciences, presenting selections from such thinkers as Charles Darwin and Sigmund Freud alongside recent work from Paul Ekman, Catherine Lutz, and others. Part Three presents some of the extensive work on emotion that developed in Europe over the past century. Part Four includes essays representing the discussion of emotions among British and American analytic philosophers. The volume is enhanced by a comprehensive introduction by the editor and a multidisciplinary bibliography. What is an Emotion? is appropriate for any course in which the nature of emotion plays a major role, including philosophy of emotion, philosophy of mind, history of psychology, emotion and motivation, moral psychology, and history and psychology of consciousness courses. The second edition provides much more material on emotions in the sciences and more from recent philosophical theories, encompassing recent shifts in theorizing on three fronts: the wealth of new information on the central nervous system and the brain; new developments in cross-cultural research and anthropology; and the recent emphasis on "cognition" in emotion, both in philosophy and the social sciences. New selections include work by Antonio Damasio, Ronald De Sousa, Paul Ekman, Nico Frijda, Patricia Greenspan, Paul Griffiths, Richard Lazarus, Catherine Lutz, Martha Nussbaum, and Michael Stocker.
