Note 85 — Chapter XII · DE ANIMÂ, ETC.
Reading edition
Aristot. De Animâ, II. viii. p. 419, b. 34 seq.: οὗτος δ’ (ὁ ἀὴρ) ἐστὶν ὁ ποιῶν ἀκούειν, ὅταν κινηθῇ συνεχὴς καὶ εἷς· — ψοφητικὸν μὲν οὖν τὸ κινητικὸν ἑνὸς ἀέρος συνεχείᾳ μέχρις ἀκοῆς. ἀκοῇ δὲ συμφυὴς ἀήρ· διὰ δὲ τὸ ἐν ἀέρι εἶναι, κινουμένου τοῦ ἔξω τὸ εἴσω κινεῖ. διόπερ οὐ πάντῃ τὸ ζῷον ἀκούει, οὐδὲ πάντῃ διέρχεται ὁ ἀήρ· οὐ γὰρ πάντῃ ἔχει ἀέρα τὸ κινησόμενον μέρος καὶ ἔμψυχον. — διὰ τὰς ἕλικας (p. 420, a. 13).
The text of this passage is not satisfactory. It has been much criticised as well as amended by Torstrick; see his Comment. p. 148 seq. I cannot approve his alteration of ἔμψυχον into ἔμψοφον.
