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.

Nothing truly stops you. Nothing truly holds you back. For your own will is always within your control. Sickness may challenge your body. But are you merely your body? Lameness may impede your legs. But you are not merely your legs. Your will is bigger than your legs. Your will needn't be affected by an incident unless you let it.

Even as the Sun doth not wait for prayers and incantations to rise, but shines forth and is welcomed by all: so thou also wait not for clapping of hands and shouts and praise to do thy duty; nay, do good of thine own accord, and thou wilt be loved like the Sun.

The universe is but one great city, full of beloved ones, divine and human, by nature endeared to each other.

The essence of good and evil is a certain disposition of the will.

You will do the greatest service to the state if you shall raise, not the roofs of the houses, but the souls of the citizens: for it is better that great souls should dwell in small houses rather than for mean slaves to lurk in great houses.

Books are the training weights of the mind.
