Note 182 — IV.

Ibid. p. 125, a. 25-32: ὁρᾶν δὲ καὶ εἰ τοῦ ἀντικειμένου τὸ ἀντικείμενον γένος, οἷον εἰ τοῦ διπλασίου τὸ πολλαπλάσιον καὶ τοῦ ἡμίσεος τὸ πολλοστημόριον· δεῖ γὰρ τὸ ἀντικείμενον τοῦ ἀντικειμένου γένος εἶναι.

We must take note here of the large sense in which Aristotle uses Ἀντικείμενα — Opposita, including as one of the four varieties Relata and Correlata = Relativé-Opposita (to use a technical word familiar in logical manuals). I have before (supra, p. 105) remarked the inconvenience of calling the Relative opposite to its Correlate; and have observed that it is logically incorrect to treat Relata as a species or mode of the genus Opposita. The reverse would be more correct: we ought to rank Opposita or a species or mode under the genus Relata. Since Aristotle numbers Relata among the ten Categories, he ought to have seen that it cannot be included as a subordinate under any superior genus.
