You're mistaken; men of sense often learn much from their enemies. Prudence is the best safeguard. This principle cannot be learnt from a friend: but an enemy extorts it immediately. It is from their foes and 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.
AristophanesChorus of women: [...] Oh! my good, gallant Lysistrata, and all my friends, be ever like a bundle of nettles; never let you anger slacken; the wind of fortune blown our way.
AristophanesComedy too can sometimes discern what is right. I shall not please, but I shall say what is true.
AristophanesCalonice: My dear Lysistrata, just what is this matter you've summoned us women to consider.What's up? Something big? Lysistrata: Very big. Calonice: (interested) Is it stout too? Lysistrata: (smiling) Yes, indeed -- both big and stout. Calonice: What? And the women still haven't come? Lysistrata: It's not what you suppose; they'd come soon enough for that.
