Isocrates, Panegyricus (50):
“In the fields of reasoning and speaking, our city has left all other people so far behind, that its students have become the teachers of all others, and it has made the name of ‘Greeks’ seem no longer to apply to a race but to a mode of thought, and has brought it about that people are called ‘Greeks’ more for sharing in our education than for sharing in our nature.”
τοσοῦτον δ᾽ ἀπολέλοιπεν ἡ πόλις ἡμῶν περὶ τὸ φρονεῖν καὶ λέγειν τοὺς ἄλλους ἀνθρώπους, ὥσθ᾽ οἱ ταύτης μαθηταὶ τῶν ἄλλων διδάσκαλοι γεγόνασι, καὶ τὸ τῶν Ἑλλήνων ὄνομα πεποίηκε μηκέτι τοῦ γένους ἀλλὰ τῆς διανοίας δοκεῖν εἶναι, καὶ μᾶλλον Ἕλληνας καλεῖσθαι τοὺς τῆς παιδεύσεως τῆς ἡμετέρας ἢ τοὺς τῆς κοινῆς φύσεως μετέχοντας.
Yes I think this has become true of many an academic.
