A concise presentation of Stoic philosophy centred on the distinction between what is within one's control and what lies beyond it, offering a structured approach to conduct and judgment. Drawn from the teachings of Epictetus, this work distils key principles concerning discipline, perception, and the ordering of thought, presenting them in a form accessible to general readers while retaining their philosophical clarity. The text emphasizes the regulation of response over the alteration of circumstance, locating freedom in the proper use of reason rather than in external conditions. Its method is aphoristic and direct, building a framework in which ethical life is understood as a matter of consistent practice rather than abstract theory. The result is a philosophy oriented toward stability, resilience, and internal coherence. Positioned within the Stoic tradition alongside the writings of Marcus Aurelius and Seneca, The Art of Living represents a modern arrangement of classical material, preserving the central insights of Epictetus while presenting them in a compact and unified form.
