ἀλλʼ εἰ μὲν οὔτε προσγίνεταί τι οὔτε ἀπογίνεται, οὐκ ἔσται κατὰ παράθεσιν τῆς ἑτέρας μονάδος τῇ ἑτέρα ἡ δυάς. εἰ δὲ ἀπογίνεταί τι κατὰ τὴν παράθεσιν, ἐλάττωσις ἔσται τοῦ ἑνὸς καὶ ἑνός, καὶ δυὰς οὐ γενήσεται. εἰ δὲ προσγίνεταί τι, τὰ δύο οὐ γενήσεται δύο ἀλλὰ τέσσαρα· δυὰς γὰρ ἡ ἐπιγινομένη καὶ μονὰς καὶ ἑτέρα μονὰς τὸν τῶν τεσσάρων ἀριθμὸν συνίστησιν. οὐδὲν ἄρα ἔσται δυάς. ἡ δὲ αὐτὴ γένοιτʼ ἂν ἀπορία καὶ ἐπὶ παντὸς ἀριθμοῦ, ὥστε μηδὲν εἶναι κατὰ τοῦτο ἀριθμόν.
