δῆλον ὅτι διαιροῖμεν ἂν τὴν μετρητικήν, καθάπερ ἐρρήθη, ταύτῃ δίχα τέμνοντες, ἓν μὲν τιθέντες αὐτῆς μόριον συμπάσας τέχνας ὁπόσαι τὸν ἀριθμὸν καὶ μήκη καὶ βάθη καὶ πλάτη καὶ ταχυτῆτας πρὸς τοὐναντίον μετροῦσιν, τὸ δὲ ἕτερον, ὁπόσαι πρὸς τὸ μέτριον καὶ τὸ πρέπον καὶ τὸν καιρὸν καὶ τὸ δέον καὶ πάνθ᾽ ὁπόσα εἰς τὸ μέσον ἀπῳκίσθη τῶν ἐσχάτων.
eng tr. Jowett 1817-1893STRANGER:
The next step clearly is to divide the art of measurement into two parts, as we have said already, and to place in the one part all the arts which measure number, length, depth, breadth, swiftness with their opposites; and to have another part in which they are measured with the mean, and the fit, and the opportune, and the due, and with all those words, in short, which denote a mean or standard removed from the extremes.
