Note 32 — Chapter III · CATEGORIÆ.
Reading edition
Waitz, ad Aristot. Categor. p. 284: “Id Categoriis non de ipsâ rerum natura et veritate exponit, sed res tales capit, quales apparent in communi vita homini philosophia non imbuto, unde fit, ut in Categoriis alia sit πρώτη οὐσία et in prima philosophia: illa enim partes habet, hæc vero non componitor ex partibus.”
Compare Metaphys. Z. p. 1032, b. 2, and the ἀπορία in Z. p. 1029, a., p. 1037, a. 28.
The different meaning of πρώτη οὐσία in the Categoriæ and in the Metaphysica, is connected with various difficulties and seeming discrepancies in the Aristotelian theory of cognition, which I shall advert to in a future chapter. See Zeller, Philos. der Griech. ii. 2, pp. 234, 262; Heyder, Aristotelische und Hegelsche Dialektik, p. 141, seq.
