Φημὶ δή, δυοῖν ἐναντίων πρὸς ἄλληλα δρώντων τε καὶ πασχόντων ἐν τῇ αὐτῇ ὕλῃ, θάτερον μὲν ἐκβάλλεσθαί τε καὶ φθείρεσθαι, θάτερον δὲ ἀντεισάγεσθαι. οὐδὲ γὰρ καὶ ἄμφω δυνατὸν ἐντελεχείᾳ ἐν τῷ αὐτῷ παρεῖναι ὑποκειμένῳ, οὐδ᾽ αὖ τοῦ αὐτοῦ ἀπεῖναι ὑποκειμένου, ἀλλὰ θατέρῳ μὲν ἐπερχομένῳ θάτερον ἀνάγκη τῆς ὕλης παραχωρῆσαι, θατέρου δὲ παραχωροῦντος, θάτερον αὖθις εἰσιέναι καὶ τὴν ὕλην εἰδοποιεῖν.
