ὅσον παιδείας χάριν: as far as it serves the purpose of education. Cf. Rep. iii. 403 e ὅσον τοὺς τύπους, Euthyd. 273 a τὴν φύσιν ὅσον. See H. 719 b; G. 160, 1. The opposite is ἐπὶ τέχνῃ, or something similar, as seen from Prot. 312 b τούτων σὺ ἑκάστην οὐκ ἐπὶ τέχνῃ ἔμαθες, ὡς δημιουργὸς ἐσόμενος, ἀλλ᾽ ἐπὶ παιδείᾳ, ὡς τὸν ἰδιώτην καὶ τὸν ἐλεύθερον πρέπει. Culture was the watchword of the time.
καὶ οὐκ αἰσχρόν: change from the καλόν to the καταγέλαστον.
