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.

Do not try to seem wise to others.

It is your own convictions which compels you; that is, choice compels choice.

When any person treats you ill or speaks ill of you, remember that he does this or says this because he thinks it is his duty. It is not possible, then, for him to follow that which seems right to you, but that which seems right to himself.

He is free who lives as he wishes to live; who is neither subject to compulsion nor to hindrance, nor to force; whose movements to action are not impeded, whose desires attain their purpose, and who does not fall into that which he would avoid.

If virtue promises happiness, prosperity and peace, then progress in virtue is progress in each of these for to whatever point the perfection of anything brings us, progress is always an approach toward it.

Any person capable of angering you becomes your master.
