Aeschylus

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

It is a light thing for whoever keeps his foot outside trouble to advise and counsel him that suffers.

Know not to revere human things too much.

Self-will in the man who does not reckon wisely is by itself the weakest of all things.

The man whose authority is recent is always stern.

And though all streams flow from a single course to cleanse the blood from polluted hand, they hasten on their course in vain.

Too few rejoice at a friend's good fortune.

Pleasantest of all ties is the tie of host and guest.

It is good even for old men to learn wisdom.

The man who does ill must suffer ill.

If you pour oil and vinegar into the same vessel, you would call them not friends but opponents.

I, schooled in misery, know many purifying rites, and I know where speech is proper and where silence.

The moving light, rejoicing in its strength, Sped from the pyre of pine, and urged its way, In golden glory, like some strange new sun.

Who, except the gods, can live time through forever without any pain?

Married love between man and woman is bigger than oaths guarded by right of nature.

You have been trapped in the inescapable net of ruin by your own want of sense.

When strength is yoked with justice, where is a mightier pair than they?

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

Death is easier than a wretched life; and better never to have born than to live and fare badly.

The one knowing what is profitable, and not the man knowing many things, is wise.

God always strives together with those who strive.
