Note 49 — Chapter V · ANALYTICA PRIORA I.
Reading edition
Ibid. p. 43, a. 39: πλὴν εἰ μὴ κατὰ δόξαν. Cf. Schol. of Alexander, p. 175, a. 44, Br.: ἐνδόξως καὶ διαλεκτικῶς, ὥσπερ εἶπεν ἐν τοῖς Τοπικοῖς, that even the principia of science may be debated; for example, in book B. of the Metaphysica. Aristotle does not recognize either τὸ ὄν or τὸ ἕν as true genera, but only as predicates.
