Aeschylus
Wisdom comes alone through suffering.
Who, except the gods, can live time through forever without any pain?
When one is willing and eager, the Gods join in.
When a match has equal partners then I fear not.
When a man's willing and eager the god's join in.
To be free from evil thoughts is God's best gift.
Time brings all things to pass.
There is no sickness worse for me than words that to be kind must lie.
There are times when fear is good. It must keep its watchful place at the heart's controls.
The wisest of the wise may err.
The man whose authority is recent is always stern.
Memory is the mother of all wisdom.
It is not the oath that makes us believe the man, but the man the oath.
It is in the character of very few men to honor without envy a friend who has prospered.
It is easy when we are in prosperity to give advice to the afflicted.
It is an easy thing for one whose foot is on the outside of calamity to give advice and to rebuke the sufferer.
It is always in season for old men to learn.
In every tyrant's heart there springs in the end this poison, that he cannot trust a friend.
I'm not afraid of storms, for I'm learning to sail my ship.
I would rather be ignorant than knowledgeable of evils.
