[ὡς] φασί, ποίᾳ χρησό- μεθα; οὔτε γὰρ πάσαις κατακολουθεῖν δυνατὸν διὰ τὸ μάχεσθαι πολλάκις, οὐτε τινὶ ἐξ αὐτῶν, ἐὰν μή τις τεχνι- κῶς προκριθῇ. ἀλλὰ πρῶτον μέν, φήσομεν, τὸ ζητεῖν ποίᾳ χρηστέον συνηθεία ἔστιν ἴσον τῷ 〈μὴ〉 εἶναί τινα τέχνην περὶ ἑλληνισμόν. αὕτη γάρ, φημὶ δʼ ἡ ἀναλογία, ὁμοίου καὶ ἀνομοίου ἐστὶ θεωρία· τὸ δέ ὅμοιον καὶ ἀνό- μοιον λαμβάνετε ἀπὸ τῆς συνηθείας· κἆν μὲν ᾖ τετριμμέ- νον, χρῆσθε αὐτῷ, εἰ δέ μή, οὐκέτι.
