Remember that even if you were to live for three thousand years, or thirty thousand, you could not lose any other life than the one you have, and there will be no other life after it. So the longest and the shortest lives are the same. The present moment is shared by all living creatures, but the time that is past is gone forever. No one can lose the past or the future, for if they don't belong to you, how can they be taken from you?

The time is at hand when you will have forgotten everything; and the time is at hand when all will have forgotten you. Always reflect that soon you will be no one, and nowhere.

The happiness and unhappiness of the rational, social animal depends not on what he feels but on what he does; just as his virtue and vice consist not in feeling but in doing.

Aptitude found in the understanding and is often inherited. Genius coming from reason and imagination, rarely.

He who has seen present things has seen all, both everything which has taken place from all eternity and everything which will be for time without end; for all things are of one kin and of one form.

When men are inhuman, take care not to feel towards them as they do towards other humans.

Nothing that goes on in anyone else's mind can harm you.
