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.
EpictetusWherever I go it will be well with me, for it was well with me here, not on account of the place, but of my judgments which I shall carry away with me, for no one can deprive me of these; on the contrary, they alone are my property, and cannot be taken away, and to possess them suffices me wherever I am or whatever I do.
EpictetusWhoever is going to listen to the philosophers needs a considerable practice in listening.
EpictetusGod has entrusted me with myself. No man is free who is not master of himself. A man should so live that his happiness shall depend as little as possible on external things. The world turns aside to let any man pass who knows where he is going.
EpictetusNothing outside the will can hinder or harm the will; it can only harm itself. If then we accept this, and, when things go amiss, are inclined to blame ourselves, remembering that judgment alone can disturb our peace and constancy, I swear to you by all the gods that we have made progress.
