Reading edition
Ibid. iii. p. 72, b. 20-30. καὶ οὐ μόνον ἐπιστήμην ἀλλὰ καὶ ἀρχὴν ἐπιστήμης εἶναι τινά φαμεν, ᾗ τοὺς ὅρους γνωρίζομεν.
Themistius, p. 14: ὧν δὴ ἄρχει πάλιν ὁ νοῦς ᾧ τοὺς ὅρους θηρεύομεν, ἐξ ὧν συγκεὶται τὰ ἀξιώματα.
The Paraphrase of Themistius (pp. 100-104) is clear and instructive, where he amplifies the last chapter, and explains Νοῦς as the generalizing or universalizing aptitude of the soul, growing up gradually out of the particulars furnished by Sense and Induction.
