Princess Diana's death was a tragedy that provoked mourning across the globe; the death of a homeless person, more often than not, is met with apathy. How can we account for this uneven distribution of emotion? Can it simply be explained by the prevailing scientific understanding? Uncovering a rich tradition beginning with Aristotle, this book offers a counterpoint to the way we generally understand emotions today. Through a radical rereading of Aristotle, Seneca, Thomas Hobbes, Sarah Fielding, and Judith Butler, among others, the book reveals a persistent intellectual current that considers emotions as psychosocial phenomena. In this historical analysis of emotion, Aristotle and Hobbes's rhetoric show that our passions do not stem from some inherent, universal nature of men and women, but rather are conditioned by power relations and social hierarchies. The book follows up with consideration of how political passions are distributed to some people but not to others using the Roman Stoics as a guide. Hume and contemporary theorists like Judith Butler, meanwhile, explain to us how psyches are shaped by power. To supplement this argument, the book also provides a history and critique of the dominant modern view of emotions, expressed in Darwinism and neurobiology, in which they are considered organic, personal feelings independent of social circumstances.
