For centuries, Stoicism was the unofficial religion of the Roman world.
The stress on endurance, self-restraint, and power of the will to withstand calamity can often seem cold-hearted. It is Epictetus, a lame former slave exiled by Emperor Domitian, who offers the most precise and humane version of Stoic ideals. The Discourses, assembled by his pupil Arrian, catch him in action, publicly setting out his views on ethical dilemmas.
Enchiridion is a distillation of his teachings and an essential manual for those seeking contentment.
