“Adolf Friedrich Bonhöffer’s The Ethics of the Stoic Epictetus is a foundational text for the modern understanding of Epictetus, instrumental in retrieving his work from its dismissals as a later ancient falling away from the rigors of the early Stoa, and indeed as a key source for our understandings of the Stoic school. Via Pierre Hadot’s work, Bonhöffer’s work also exerts an indirect influence over the contemporary revival of Stoicism as a way of life around the world. This text, carefully translated by William O. Stephens, is an essential text for any student of Stoicism today.”—Matthew Sharpe, Deakin University (Australia)
