A concise manual of Stoic philosophy, presenting practical guidance on self-mastery, judgment, and the disciplined use of reason. The Enchiridion (or "Handbook") distills the teachings of Epictetus, a former slave turned philosopher, into a series of short, direct reflections on how to live in accordance with nature and reason. Compiled by his student Arrian in the second century CE, the work emphasizes the distinction between what lies within our control and what does not, offering a framework for achieving inner freedom regardless of external circumstance. The text is notable for its clarity and austerity, avoiding speculative argument in favor of moral instruction. It addresses the formation of character, the management of desire and aversion, and the cultivation of resilience in the face of adversity. As one of the most accessible expressions of Stoic thought, the Enchiridion has been read continuously for centuries, influencing philosophical, religious, and practical traditions concerned with discipline, detachment, and ethical conduct. This edition presents the classic English translation by Elizabeth Carter, preserving the directness and force of Epictetus's teaching while remaining accessible to the modern reader.
