οἷον εἰ τὸ μὲν Α τῷ Β ἐξ ἀνάγκης εἴληπται ὑπάρχον ἢ μὴ ὑπάρχον. Περὶ τῶν δύο συζυγιῶν λέγει τῶν ἐν τῷ πρώτῳ σχήματι πρώτων· καὶ γὰρ καταφατικῆς καὶ καθόλου ἀναγκαίας οὔσης τῆς μείζονος ὑπαρχούσης δὲ καθόλου καταφατικῆς τῆς ἐλάττονος καὶ ἀποφατικῆς ὁμοίως ἀναγκαίας πάλιν τῆς μείζονος ὑπαρχούσης δὲ καθόλου καταφατικῆς τῆς ἐλάττονος ἀναγκαῖόν φησι τὸ συμπέρασμα γίνεσθαι, ἐν ᾗ μὲν καταφατικόν, ἐν ᾗ δὲ ἀποφατικὸν· ἐπεὶ γὰρ παντὶ τῷ Β ἐξ ἀνάγκης ὑπάρχειν ἢ μὴ ὑπάρχειν τὸ Α κεῖται, τὸ δὲ Γ τὶ τῶν Β ἐστί, φανερόν, ὅτι καὶ τῷ Γ ἐξ ἀνάγκης ἔσται θάτερον τούτων. Τὸ μὲν θάτερον τούτων εἴρηκεν ἀντὶ τοῦ ‘καταφατικὸν ἢ ἀποφατικόν᾿. 35 δι’ ·ὃ δὲ ἡγεῖται ἀναγκαῖον ἔσεσθαι τὸ συμπέρασμα οὕτως ἐχόντων τῶν ;]0 ὅρων, εἴρηκεν, ὅτι τὸ μὲν Γ τὶ τῶν Β ἐστί, τὸ δὲ Α παντὶ τῷ Β ἐξ ἀνάγκης κεῖται ὑπάρχειν ἢ μὴ ὑπάρχειν.
