Demosthenes: A demagogue must be neither an educated nor an honest man; he has to be an ignoramus and a rogue. (tr. O'Neill 1938, Perseus) - Aristophanes

A demagogue must be neither an educated nor an honest man; he must be ignorant and a rogue.

Epops: You're mistaken: men of sense often learn from their enemies. Prudence is the best safeguard. This principle cannot be learned from a friend, but an enemy extorts it immediately. It is from their foes, not their friends, that cities learn the lesson of building high walls and ships of war. And this lesson saves their children, their homes, and their properties. Chorus [leader]: It appears then that it will be better for us to hear what they have to say first; for one may learn something at times even from one's enemies. (tr. Anon. 1812 rev. in Ramage 1864, p. 45)

Numai moartea nu cere daruri dintre zei.

Cho. O mortal, who hast desired great wisdom from us!
How happy will you become among the Athenians and among
the Greeks, if you be possessed of a good memory, and be
a deep thinker, and endurance of labour be implanted in
your soul, and you be not wearied either by standing or
walking, nor be exceedingly vexed at shivering with
cold, nor long to break your fast, and you refrain from
wine, and gymnastics, and the other follies, and
consider this the highest excellence, as is proper a
clever man should, to conquer by action and counsel, and
by battling with your tongue.
