Plato, Laws 646d

κάλλιστα. οὐκοῦν χρὴ καὶ τῶν ἄλλων ἐπιτηδευμάτων πέρι διανοεῖσθαι τὸν αὐτὸν τρόπον; πάνυ γε. καὶ τῆς περὶ τὸν οἶνον ἄρα διατριβῆς ὡσαύτως διανοητέον, εἴπερ ἔνι τοῦτο ἐν τούτοις ὀρθῶς διανοηθῆναι. πῶς δʼ οὔ; ἂν ἄρα τινὰ ἡμῖν ὠφελίαν ἔχουσα φαίνηται μηδὲν τῆς περὶ τὸ σῶμα ἐλάττω, τῇ γε ἀρχῇ τὴν σωμασκίαν νικᾷ τῷ τὴν μὲν μετʼ ἀλγηδόνων εἶναι, τὴν δὲ μή.

Quite true. Should one not take the same view of the other institutions also? Certainly. Then one must also take the same view of the practice of wine-drinking, if one can rightly class it amongst the others. Of course one must. If then this practice should be shown to be quite as beneficial for us as bodily training, certainly at the outset it is superior to it, in so far as it is not, like bodily training, accompanied by pain.
