This book acts both as an introduction to Stoic ethics and as a challenge to scholars to think about Stoic ethics, as opposed to Aristotle, as a better ancient prototype for modern virtue ethics. Gill cautions in his preface that this is not meant as “life guidance for a general audience” (p. ix), but rather a reading of Stoic ethics framed in three parts: “Living Naturally”, “Learning to Live Naturally”, and “Stoic Ethics and Modern Moral Theory”. Like the Stoic triad of ethics, physics, and logic, these three parts are intertwined and shed light on one another in important ways. Gill is a sure guide to the material and the arguments, while dense at times, are persuasive throughout.
