Note 26 — Chapter III · CATEGORIÆ.
Reading edition
Categor. p. 3, a. 3. In the Physica, iv. p. 210, a. 14-30, Aristotle enumerates nine different senses of the phrase ἕν τινι. His own use of the phrase is not always uniform or consistent. If we compare the Scholia on the Categoriæ, pp. 44, 45, 53, 58, 59, Br., with the Scholia on the Physica, pp. 372, 373, Br., we shall see that the Commentators were somewhat embarrassed by his fluctuation. The doctrine of the Categoriæ was found especially difficult in its application to the Differentia.
In Analyt. Post. i. p. 83, a. 30, Aristotle says, ὅσα δὲ μὴ οὐσίαν σημαίνει, δεῖ κατά τινος ὑποκειμένου κατηγορεῖσθαι, which is at variance with the language of the Categoriæ, as the Scholiast remarks, p. 228, a. 33. The like may be said about Metaphys. B. p. 1001, b. 29; Δ. p. 1017, b. 13. See the Scholia of Alexander, p. 701, b. 25, Br.
See also De Gener. et Corrupt. p. 319, b. 8; Physic. i. p. 185, a. 31: οὐθὲν γὰρ τῶν ἄλλων χωριστόν ἐστι παρὰ τὴν οὐσίαν· πάντα γὰρ καθ’ ὑποκειμένου τῆς οὐσίας λέγεται, where Simplikius remarks that the phrase is used ἀντὶ τοῦ ἐν ὑποκειμένῳ (Schol. p. 328, b. 43).
