Note 14 — Chapter IV · DE INTERPRETATIONE.
Reading edition
Aristot. De Interpr. p. 17, a. 37-b. 14: ἐπεὶ δ’ ἐστὶ τὰ μὲν καθόλου τῶν πραγμάτων, τὰ δὲ καθ’ ἕκαστον (λέγω δὲ καθόλου μὲν ὃ ἐπὶ πλειόνων πέφυκε κατηγορεῖσθαι, καθ’ ἕκαστον δὲ ὃ μὴ, οἷον ἄνθρωπος μὲν τῶν καθόλου, Καλλίας δὲ τῶν καθ’ ἕκαστον)· &c. Ammonius (in Schol. p. 113, a. 38) says that what is predicated, either of many subjects or of one, must be μία φύσις.
The warning against quantifying the predicate appears in this logical treatise of Aristotle, and is repeated in the Analytica Priora, I. xxvii. p. 43, b. 17. Here we have: οὐδεμία κατάφασις ἀληθὴς ἔσται, ἐν ᾗ τοῦ κατηγορουμένου καθόλου τὸ καθόλου κατηγορεῖται, οἷον ἔστι πᾶς ἄνθρωπος πᾶν ζῷον (b. 14).
