Retrieving Political Emotion engages the reader in an excursion through our ancient Greek heritage to recover a concept of emotion useful for enriching political philosophy today. Focusing on thumos (typically translated as "spiritedness," "heart," or "anger"), Barbara Koziak reveals misinterpretations of the concept that have hampered recognition of its possibilities for normative theory. Then, drawing especially on Aristotle's construal of it as a general capacity for emotion and relating this to contemporary multidisciplinary work on emotion, she reformulates thumos to provide a more adequate theory of political emotion, as an antidote to the modern fixation on rational self-interest as the key to explaining political behavior.
