Let every man remind their descendants that they also are soldiers who must not desert the ranks of their ancestors, or from cowardice fall behind.

The soul should concentrate itself by itself.

Virtue is a kind of health, beauty and good habit of the soul.

And when one of them meets the other half, the actual half of himself, whether he be a lover of youth or a lover of another sort, the pair are lost in an amazement of love and friendship and intimacy and one will not be out of the other's sight, as I may say, even for a moment.

The cause of all the blunders committed by man arises from this excessive self-love. For the lover is blinded by the object loved; so that he passes a wrong judgment on what is just, good and beautiful, thinking that he ought always to honor what belongs to himself in preference to truth. For he who intends to be a great man ought to love neither himself nor his own things, but only what is just, whether it happens to be done by himself, or by another.

To fear death, my friends, is only to think ourselves wise without really being wise, for it is to think that we know what we do not know.

Knowledge becomes evil if the aim be not virtuous.
