ῥητορικὸς δʼ ἐστὶν ὁ τρόπος τῆς ἐπαγωγῆς οὗτος, ἐπειδὴ καὶ ἡ ῥητορικὴ περὶ τὰ ἐπὶ μέρους, οὐ τὰ καθόλου τὴν πραγματείαν ἔχει. ζητεῖ γὰρ οὐ περὶ αὐτοῦ τοῦ δικαίου, ἀλλὰ τῶν ἐπὶ μέρους δικαίων. ὁ δὲ ἕτερός ἐστι διαλεκτικός, προαποδειχθέντος τοῦ καθόλου διὰ τῶν ἐπὶ μέρους. οἷον ζητεῖται, εἰ ἡ ψυχὴ ἀθάνατος καὶ εἰ ἐκ τῶν τεθνεώτων οἱ ζῶντες· ὅπερ ἀποδείκνυται ἐν τῷ Περὶ ψυχῆς διά τινος καθολικοῦ, ὅτι ἐκ τῶν ἐναντίων τὰ ἐναντία. καὶ αὐτὸ δὲ τὸ καθόλου κατασκευάζεται ἔκ τινων ὄντων ἐπὶ μέρους· οἷον ὅτι τὸ καθεύδειν ἐκ τοῦ ἐγρηγορέναι καὶ ἀνάπαλιν καὶ τὸ μεῖζον ἐκ τοῦ μικροτέρου καὶ ἀνάπαλιν. τούτῳ δὲ ἐχρῆτο εἰς τὴν τῶν ἑαυτῷ δοκούντων κατασκευήν.
