Ὁ δὲ ψευδὴς λόγος γίνεται παρὰ τὸ πρῶτον ψεῦδος. Ἢ γὰρ ἐκ τῶν δύο προτάσεων ἢ ἐκ πλειόνων πᾶς ἐστὶ συλλογισμός. Εἰ μὲν οὖν ἐκ τῶν δύο, τούτων ἀνάγκη τὴν ἑτέραν ἢ καὶ ἀμφοτέρας εἶναι ψευδεῖς· ἐξ ἀληθῶν γὰρ οὐκ ἦν ψευδὴς συλλογισμός. Εἰ δ᾿ ἐκ πλειόνων, οἷον τὸ μὲν Γ διὰ τῶν Α Β, ταῦτα δὲ διὰ τῶν Δ Ε Ζ Η, τούτων τι ἔσται τῶν ἐπάνω ψεῦδος, καὶ παρὰ τοῦτο ὁ λόγος· τὸ γὰρ Α καὶ Β δι᾿ ἐκείνων περαίνονται. Ὥστε παρ᾿ ἐκείνων τι συμβαίνει τὸ συμπέρασμα καὶ τὸ ψεῦδος.
