Note 25 — Chapter IV · DE INTERPRETATIONE.
Reading edition
Aristot. De Interpr. p. 19, b. 36. αὗται μὲν οὖν δύο ἀντίκεινται (the two pairs — A B and C D — of the first quaternion), ἄλλαι δὲ δύο πρὸς τὸ οὐκ ἄνθρωπος ὡς ὑποκείμενόν τι προστεθέν·
(E) ἔστι δίκαιος οὐκ ἄνθρωπος … … … … (F) οὐκ ἔστι δίκαιος οὐκ ἄνθρωπος.
(H) οὐκ ἔστιν οὐ δίκαιος οὐκ ἄνθρωπος … … … … (G) ἔστιν οὐ δίκαιος οὐκ ἄνθρωπος.
πλείους δὲ τούτων οὐκ ἔσονται ἀντιθέσεις. αὗται δὲ χωρὶς ἐκείνων αὐταὶ καθ’ ἑαυτὰς ἔσονται, ὡς ὀνόματι τῷ οὐκ ἄνθρωπος χρώμεναι. The second αὗται alludes to this last quaternion, ἐκείνων to the first. I have, as in the former case, transposed propositions three and four of this second quaternion, in order that the relation of G to F and of H to E may be more easily discerned.
There are few chapters in Aristotle more obscure and puzzling than the tenth chapter of the De Interpretatione. It was found so by Alexander, Herminus, Porphyry, Ammonius, and all the Scholiasts. Ammonius (Schol. pp. 121, 122, Br.) reports these doubts, and complains of it as a riddle almost insolvable. The difficulties remain, even after the long note of Waitz, and the literal translation of M. Barthélemy St. Hilaire.
