This unique volume offers an odyssey through the ideas of the Stoics in three particular ways: first, through the historical trajectory of the school itself and its influence; second, through the recovery of the history of Stoic thought; third, through the ongoing confrontation with Stoicism, showing how it refines philosophical traditions, challenges the imagination, and ultimately defines the kind of life one chooses to lead. A distinguished roster of specialists have written an authoritative guide to the entire philosophical tradition. The first two chapters chart the history of the school in the ancient world, and are followed by chapters on the core themes of the Stoic system: epistemology, logic, natural philosophy, theology, determinism, and metaphysics. There are two chapters on what might be thought of as the heart and soul of the Stoics system: ethics.
