Καὶ ἐὰν τὸ μὲν P παντὶ τῷ Σ, τὸ δὲ Π μηδενί. Ἐπὶ δευτέραν συζυγίαν μετελήλυθε τὴν ἐκ καθόλου ἀποφατικῆς τῆς μείζονος καὶ καθόλου καταφατικῆς τῆς ἐλάττονος, καὶ δείκνυσι καὶ ταύτην συλλογιστικὴν διὰ τοῦ ἀντιστρέψαι τὴν ἐλάττονα τὴν P Σ οὖσαν καθόλου καταφατικὴν καὶ λαβεῖν ἐπὶ μέρους καταφατικὴν τὴν P Σ καὶ ἀναγαγεῖν εἰς τὸν ἐν πρώτῳ σχήματι τέταρτον συλλογισμόν, ὃς ἦν ἐκ καθόλου ἀποφατικῆς τῆς μείζονος καὶ ἐπὶ μέρους καταφατικῆς τῆς ἐλάττονος ἐπὶ μέρους ἀποφατικὸν συνάγων. δῆλον δ‘, ὅτι ἔνεστι καὶ διὰ τῆς εἰς ἀδύνατον ἀπ- γωγῆς δεῖξαι καὶ τοῦτον, ὡς λέγει, καὶ σαφὲς τὸ συναγόμενον ἀδύνατον· ἄν γὰρ ὑποτεθῇ τὸ Π παντὶ τῷ P, ἐπεὶ τὸ P ἔκειτο παντὶ τῷ Σ, συναχθήσεται τὸ 11 παντὶ τῷ Σ, ᾧ ἔκειτο μηδενὶ ὑπάρχειν. ἀλλὰ καὶ τῷ ἐκθέσθαι ἔνεστι προσχρησαμένους ὁμοίως πάλιν δεῖξαι, | εἰ καὶ μὴ αὐτὸς ἐμνημόνευσεν. ἂν γάρ τι τοῦ Σ αἰσθητὸν λάβωμεν, τῷ τοῦτο ἐναργῶς ἐν μὲν τῷ P εἶναι καὶ μετέχειν αὐτοῦ τοῦ δὲ Π μὴ κοινωνεῖν φανερὸν ἔσται, ὅτι τὸ Π τινὶ τῷ P οὐχ ὑπάρχει· τούτῳ γὰρ τῷ ἐκκειμένῳ καὶ εἰλημμένῳ οὐχ ὑπάρξει ὄντι τινὶ τοῦ P.
