This volume draws together important selections from the rich history of theories and debates about emotion. Utilizing sources from a variety of subject areas including philosophy, psychology, and biology, the editors provide an illuminating look at the "affective" side of psychology and philosophy from the perspective of the world's great thinkers. Part One features classic readings from Aristotle, Descartes, Spinoza, and Hume. Part Two, entitled "The Meeting of Philosophy and Psychology," samples the theories of thinkers such as Darwin, James, and Freud. The third section presents some of the extensive work on emotion that has been done by European philosophers over the past century, and the final section comprises essays from modern British and American philosophers.
