Λείπεται τοίνυν μόνον ἐν τῷ τῆς κινήσεως ἄκρῳ τε καὶ ἐσχάτῳ τὸ μὲν τῶν ἐναντίων πάντη φθαρῆναι καὶ μηκέτι εἶναι, τὸ δὲ ἀντεισαχθῆναι κατὰ τὸ αὐτὸ νῦν τοῦ χρόνου, ὃ καὶ ὅρος ἐστὶ τῆς κινήσεως ὁ εἰς ὅ· καὶ μεταξὺ δὲ τοῖν δυοῖν ὅροιν, τοῦ τ᾽ ἐξ οὗ, τοῦ τ᾽ εἰς ὅ, πολλὰ τῶν μέσων εἰδῶν ἀνάγκη γίγνεσθαι δήπου, τοῦ μὲν προηγούμενα, τοῦ εἰς ὅ, τῷ δ᾽ ἑπόμενα, τῷ ἐξ οὗ, ἃ οὐδέτερον τῶν ἄκρων οὔτ᾽ ἐστιν, οὔτε λέγεται, οἷον φαιόν, ὠχρόν, ἐρυθρὸν καὶ τἄλλα τῶν μέσων, εἰς ἃ πρῶτον μεταβάλλει τὸ ἐκ τοῦ μέλανος εἰς λευκὰ μεταβάλλον, ὅ οὔτ᾽ ἔστιν, οὔτε λέγεται λευκὸν ἢ μέλαν ἁπλῶς, εἰ μήπου τοῖν δυοῖν ἄκροιν παραβαλλόμενον, πρὸς ἐκεῖνο μὲν μέλαν, πρὸς δὲ τοῦτο λευκὸν λέγοιτ᾽ ἄν, ἁπλῶς δὲ οὐκ ἔστιν, εἰ μή τις τὰ εἴδη συγχέειν βούλοιτο.
