Wise people, even though all laws were abolished, would still lead the same life. - Aristophanes

Demosthenes: Do you dare to accuse wine of clouding the reason? Quote me more marvellous effects than those of wine. Look! when a man drinks, he is rich, everything he touches succeeds, he gains lawsuits, is happy and helps his friends. Come, bring hither quick a flagon of wine, that I may soak my brain and get an ingenious idea. (tr. O'Neill 1938, Perseus)

DICAEOPOLIS
Friends, leave the Laconians out of debate and consider only
whether I have not done well to conclude my truce.
CHORUS
Done well! when you have treated with a people who know neither
gods, nor truth, nor faith.
DICAEOPOLIS
We attribute too much to the Laconians; as for myself, I know that
they are not the cause of all our troubles.
CHORUS
Oh, indeed, rascal! You dare to use such language to me and then
expect me to spare you!
DICAEOPOLIS
No, no, they are not the cause of all our troubles, and I who
address you claim to be able to prove that they have much to
complain of in us.
CHORUS
This passes endurance; my heart bounds with fury. Thus you dare to
defend our enemies.
DICAEOPOLIS
Were my head on the block I would uphold what I say and rely on
the approval of the people.
CHORUS
Comrades, let us hurl our stones and dye this fellow purple.
DICAEOPOLIS
What black fire-brand has inflamed your heart! You will not hear
me? You really will not, Acharnians?
CHORUS
No, a thousand times, no.
DICAEOPOLIS
This is a hateful injustice.
CHORUS
May I die, if I listen.
DICAEOPOLIS
Nay, nay! have mercy, have mercy, Acharnians.
CHORUS
You shall die.
DICAEOPOLIS
Well, blood for blood! I will kill your dearest friend.

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