Plato, Laws 646a

ἥκιστα. ἆρʼ οὖν πονηρότατος, φαμέν, ὁ τοιοῦτος; πολύ γε. οὐ μόνον ἄρʼ, ὡς ἔοικεν, ὁ γέρων δὶς παῖς γίγνοιτʼ ἄν, ἀλλὰ καὶ ὁ μεθυσθείς. ἄριστα εἶπες, ὦ ξένε. τούτου δὴ τοῦ ἐπιτηδεύματος ἔσθʼ ὅστις λόγος ἐπιχειρήσει πείθειν ἡμᾶς ὡς χρὴ γεύεσθαι καὶ μὴ φεύγειν παντὶ σθένει κατὰ τὸ δυνατόν; ἔοικʼ εἶναι· σὺ γοῦν φῂς καὶ ἕτοιμος ἦσθα νυνδὴ λέγειν.

Very little. And such a man is, we say, very bad? Very, indeed. It appears, then, that not the grey-beard only may be in his second childhood, but the drunkard as well. An admirable observation, Stranger. Is there any argument which will undertake to persuade us that this is a practice we ought to indulge in, instead of shunning it with all our might so far as we possibly can? It appears that there is: at any rate you assert this, and you were ready just now to argue it.
