Note 41 — Chapter V · ANALYTICA PRIORA I.
Reading edition
Ibid. p. 41, b. 23: πάντες γὰρ οἱ διὰ τοῦ ἀδυνάτου περαίνοντες τὸ μὲν ψεῦδος συλλογίζονται, τὸ δ’ ἐξ ἀρχῆς ἐξ ὑποθέσεως δεικνύουσιν, ὅταν ἀδύνατόν τι συμβαίνῃ τῆς ἀντιφάσεως τεθείσης.
It deserves to be remarked that Aristotle uses the phrase συλλογισμὸς ἐξ ὑποθέσεως, not συλλογισμὸς ὑποθετικός. This bears upon the question as to his views upon what subsequently received the title of hypothetical syllogisms; a subject to which I shall advert in a future note.
