Epictetus, a Stoic philosopher, presents a guide to life based on a key distinction: what depends on us and what does not. Through clear and direct maxims, he encourages control of one’s thoughts, acceptance of external events, and cultivation of inner freedom. Far from illusions and useless passions, he shows how to attain serenity by living according to reason. This concise and powerful text offers a practical philosophy oriented toward action and self-mastery, for facing difficulties with lucidity and calm.
