Now departure from the world of men is nothing to fear, if gods exist: because they would not involve you in any harm. If they do not exist, or if they have no care for humankind, then what is life to me in a world devoid of gods, or devoid of providence? But they do exist, and they do care for humankind: and they have put it absolutely in man's power to avoid falling into the true kinds of harm.

There is but one thing of real value - to cultivate truth and justice, and to live without anger in the midst of lying and unjust men.

The best way of avenging thyself is not to become like the wrong-doer.

Do not consider anything for your interest which makes you break your word, quit your modesty or inclines you to any practice which will not bear the light or look the world in the face.

Let it be your constant method to look into the design of people's actions, and see what they would be at, as often as it is practicable; and to make this custom the more significant, practice it first upon yourself.

The longest-lived and the shortest-lived man, when they come to die, lose one and the same thing.
