To Epictetus, all external events are determined by fate, and are thus beyond our control, but we can accept whatever happens calmly and dispassionately. Individuals, however, are responsible for their own actions which they can examine and control through rigorous self-discipline. Suffering arises from trying to control what is uncontrollable, or from neglecting what is within our power. As part of the universal city that is the universe, human beings have a duty of care to all fellow humans. The person who followed these precepts would achieve happiness.

We do not choose our own parts in life, and have nothing to do with those parts. Our duty is confined to playing them well.

Control thy passions lest they take vengence on thee.

Liars are the cause of all the sins and crimes in the world.

Not things, but opinions about things, trouble men.

If you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase.

Let death and exile, and all other things which appear terrible be daily before your eyes, but chiefly death, and you win never entertain any abject thought, nor too eagerly covet anything.
