Plato, Laws 809b

σαφὲς οὐδὲ ἱκανόν, ἀλλὰ τὰ μέν, τὰ δʼ οὔ· δεῖ δὲ εἰς δύναμιν μηδὲν παραλείπειν αὐτῷ, πάντα δὲ λόγον ἀφερμηνεύειν, ἵνα οὗτος τοῖς ἄλλοις μηνυτής τε ἅμα καὶ τροφεὺς γίγνηται. τὰ μὲν οὖν δὴ χορείας πέρι μελῶν τε καὶ ὀρχήσεως ἐρρήθη, τίνα τύπον ἔχοντα ἐκλεκτέα τέ ἐστιν καὶ ἐπανορθωτέα καὶ καθιερωτέα· τὰ δὲ ἐν γράμμασι μὲν ὄντα, ἄνευ δὲ μέτρων, ποῖα καὶ τίνα μεταχειρίζεσθαι χρή σοι τρόπον, ὦ ἄριστε τῶν

adequate statement: it has mentioned some things, but omitted others. But in dealing with this warden it must omit nothing, but fully expound every ordinance that he may be both expositor and nurturer to the rest. Matters of choristry of tunes and dancing, and what types are to be selected, remodelled, and consecrated—all this has already been dealt with; but with regard to the kind of literature that is written but without meter we have never put the question—O excellent supervisor of children, of what sort ought this prose to be, and in what fashion are your charges to deal with it?
