Note 69 — Chapter VII · PLATONIC CANON AS APPRECIATED AND MODIFIED BY MODERN CRITICS.
Reading edition
Compare Plat. Protag. 312 A-B, 315 A, where the distinction is pointedly drawn between one who visited Protagoras ἐπὶ τέχνῃ, ὡς δημιουργὸς ἐσόμενος, and others who came simply ἐπὶ παιδείᾳ, ὡς τὸν ἰδιώτην καὶ τὸν ἐλεύθερον πρέπει.
