Note 142 — Chapter III · CATEGORIÆ.
Reading edition
Categ. p. 11, b. 16: περὶ δὲ τῶν ἀντικειμένων, ποσαχῶς εἴωθεν ἀντικεῖσθαι ῥητέον. See Simpl. in Schol. p. 81, a. 37-b. 24. Whether Aristotle reckoned τὰ ἀντικείμενα a true genus or not, was debated among the commentators. The word ποσαχῶς implies that he did not; and he treats even the term ἐναντία as a πολλαχῶς λεγόμενον, though it is less wide in its application than ἀντικείμενα, which includes Relata (Metaphys. I. p. 1055, a. 17). He even treats στέρησις as a πολλαχῶς λεγόμενον (p. 1055, a. 34).
Αἱ ἀντιθέσεις τέσσαρες, the four distinct varieties of τὰ ἀντικείμενα are enumerated by Aristotle in various other places:— Topic. ii. p. 109, b. 17; p. 113, b. 15; Metaphys. I. p. 1055, a. 38. In Metaphys. Δ. p. 1018, a. 20, two other varieties are added. Bonitz observes (ad Metaph. p. 247) that Aristotle seems to treat this quadripartite distribution of Opposita, “tanquam certum et exploratum, pariter ac causarum numerum,” &c.
