Why does anger erupt so suddenly—and why does it cling so stubbornly to our lives? In this thought-provoking first volume of the Possessed series, philosopher and psychologist Gustavo Faigenbaum examines one of humanity’s most volatile and misunderstood emotions. Beginning with Achilles’ legendary wrath in Homer’s Iliad, Faigenbaum shows how anger often arises when something we consider ours—our body, our dignity, our place in the world—is threatened. Drawing on Plato’s vision of the soul as a miniature state, he argues that anger, when consciously possessed and rightly directed, becomes a force capable of defending core values, confronting injustice, and guiding the soul toward harmony and reason. Blending insights from ancient philosophy, modern psychology, neuroscience, and cultural history, Anger makes a powerful case for transforming a primal survival impulse into a tool of self-governance. Accessible yet profound, this book invites readers not merely to suppress anger, but to transform it. Whether you're drawn to philosophy, psychology, or simply seeking deeper emotional insight, Anger offers a compelling path toward ethical clarity and self-understanding.
