Epictetus, who had heard lectures by the Stoic Musonius Rufus, taught a practical philosophy, details of which survive in four books of Discourses and a smaller Encheiridion, a handbook which gives briefly the chief doctrines of the Discourses.

The famous Meditations of Marcus Aurelius, Roman emperor and Stoic philosopher, represents reflections written in periods of solitude during the emperor’s military campaigns. Originally intended for his private guidance and self-admonition, the Meditations has endured as a potent expression of Stoic belief. It is a central text for students of Stoicism as well as a unique personal guide to the moral life.
