Aeschylus

For there is no defense for a man who, in the excess of his wealth, has kicked the great altar of Justice out of sight.

Alas for the affairs of men! When they are fortunate you might compare them to a shadow; and if they are unfortunate, a wet sponge with one dash wipes the picture away.

I know how men in exile feed on dreams.

The evils of mortals are manifold; nowhere is trouble of the same wing seen.

It is a profitable thing, if one is wise, to seem foolish.

If a man suffers ill, let it be without shame; for this is the only profit when we are dead. You will never say a good word about deeds that are evil and disgraceful.

His resolve is not to seem the bravest, but to be.

For somehow this disease inheres in tyranny, never to trust one's friends.

Who apart from the gods is without pain for his whole lifetime's length?

It is good even for old men to learn wisdom.
