Τὸ γὰρ μεταβάλλον οὐ μεταβέβληκεν, εἰ μή τις λέγειν ἐθέλει πᾶν τὸ μεταξὺ εἶδος καὶ πᾶσαν ἀπόστασιν πυρώδη καὶ θερμότητα καὶ δυνάμει μόνον οὖσαν, ἐντελεχείᾳ δὲ οὔ· τὸ γὰρ κινούμενον δυνάμει τοῦ πρὸς ὃ κινεῖται, οὐκ ἐντελεχείᾳ· οὐ γὰρ ἂν ἐκινεῖτο, ἀλλ᾽ ἠρέμει, τοιοῦτον ἐντελεχείᾳ ὄν, οἷον τὸ πρὸς ὃ κινεῖται· ἄλλως γὰρ κινούμενον τὸ αὐτό, καὶ μὴ κινούμενον κατὰ τὸ αὐτὸ καὶ ἐν τῷ αὐτῷ γ᾽ εἴη ἄν, ὅπερ ἀντίφασις· ὅ γε μὴν ἑκτικὸς πυρετὸς ἔστι μὲν ὡς τὸ κατὰ φύσιν θερμὸν εἰς τὸ πυρῶδες μεταβάλλον, ἔστι δὲ ὡς οὔ.
