Eva Brann considers what the great philosophers on the passions and feelings have thought and written about them. She examines the relevant work of Plato, Aristotle, the Stoics, Aquinas, Descartes, Spinoza, Adam Smith, Hume, Kierkegaard, and Heidegger, and also includes a chapter on contemporary studies on the brain. This book provides a comprehensive look at this pervasive and elusive topic.
