καὶ δὴ τὸ ὡρισμένον τοῦτο ἀξίωμα, τὸ “οὗτος κάθηται” ἢ “οὗτος περιπατεῖ”, τότε φασὶν ἀληθὲς ὑπάρχειν, ὅταν τῷ ὑπὸ τὴν δεῖξιν πίπτοντι συμβεβήκῃ τὸ κατηγόρημα, οἷον τὸ καθῆσθαι ἢ τὸ περιπατεῖν. ἀλλ’ ἔν τε τῷ λέγειν “οὗτος περιπατεῖ” δεικνυμένου τινὸς τῶν ἐπὶ μέρους ἀνθρώπων, ἤτοι Σωκράτης ἐστὶ λόγου χάριν ὁ ὑπὸ τὴν δεῖξιν πίπτων ἢ μέρος τι τοῦ Σωκράτους· οὔτε δὲ Σωκράτης ἐστὶν ὁ ὑπὸ τὴν δεῖξιν πίπτων οὔτε μέρος τι τοῦ Σωκράτους, ὧς παραστήσομεν· οὐκ ἄρα δύναται ἀληθὲς εἶναι τὸ ὡρισμένον ἀξίωμα.
