What makes us angry—and why? In the opening volume of the Possessed series, philosopher Gustavo Faigenbaum takes readers on a captivating journey into the heart of anger, guided by Plato's profound insights. Beginning with Achilles' legendary wrath in Homer's Iliad, Faigenbaum explores how anger arises from threats to what we deeply regard as "ours"—our honor, status, or self-worth. Drawing connections between ancient philosophy, neuroscience, psychology, and cultural history, this book reveals how anger has evolved from a primal survival response into a complex social emotion, deeply entwined with ownership, justice, and self-governance. Engaging, thought-provoking, and profoundly relevant, Anger invites readers to understand this powerful emotion and transform it into a source of insight and moral clarity.
