Aristophanes

A man may learn wisdom even from a foe.

Your lost friends are not dead, but gone before, advanced a stage or two upon that road which you must travel in the steps they trod.

Why, I'd like nothing better than to achieve some bold adventure, worthy of our trip.

These impossible women! How they do get around us! The poet was right: Can't live with them, or without them.

Let each man exercise the art he knows.

You cannot make a crab walk straight.

Thou shouldst not decide until thou hast heard what both have to say.

Evil events from evil causes spring.

The truth is forced upon us very quickly by a foe.

Under every stone lurks a politician.

It is from their foes, not their friends, that cities learn the lesson of building high walls

Chorus of old men: How true the saying: 'Tis impossible to live with the baggages, impossible to live without 'em.

Comedy too can sometimes discern what is right.
