§15.1Fr. 15
Θ. ἐν τοῖς ἑαυτοῦ Τοπικοῖς τάδε γέγραφεν Ἐπεὶ δὲ ἐναντίαι τῶν ἐναντίων αἱ ἀρχαὶ, δῆλον ὅτι οὐδὲ ἐν ἑνὶ γένει ταῦτα, καθάπερ οὐδὲ τὸ ἀγαθὸν καὶ κακὸν καὶ κίνησις καὶ στάσις.
Fr. 15 Theophrastus has written the following in his Topics: "Since the principles of contraries are themselves contrary, it is clear that these are not even in a single genus, just as neither are good and bad, and motion and rest.
Εἴη δʼ ἂν καὶ ὑπεροχὴ καὶ ἔλλειψις ἐναντία γε καὶ ἀρχαὶ, καὶ εἶδος καὶ στέρησις.
And excess and deficiency might also be contraries and indeed principles, as well as form and privation."
