Note 44 — Chapter VIII · PLATONIC COMPOSITIONS GENERALLY.
Reading edition
Themistius mentions it as a fact recorded (I wish he had told us where or by whom) that Aristotle stoutly opposed the Platonic doctrine of Objective Ideas, even during the lifetime of Plato, ἱστορεῖται δὲ ὅτι καὶ ζῶντος τοῦ Πλάτωνος καρτερώτατα περὶ τούτου τοῦ δόγματος ἐνέστη ὁ Ἀριστοτέλης τῷ Πλάτωνι. (Scholia ad Aristotel. Analyt. Poster. p. 228 b. 16 Brandis.)
