Aristotle, Nicomachean Ethics, Book 3 142:

οὐδ’ ὁ λέων τῇ φωνῇ τοῦ βοὸσ ἀλλὰ τῇ ἐδωδῇ· ὅτι δ’ ἐγγύσ ἐστι, διὰ τῆσ φωνῆσ ᾔσθετο, καὶ χαίρειν δὴ ταύτῃ φαίνεται· ὁμοίωσ δ’ οὐδ’ ἰδὼν "ἢ εὑρὼν ἔλαφον ἢ ἄγριον αἶγα," ἀλλ’ ὅτι βορὰν ἕξει. περὶ τὰσ τοιαύτασ δ’ ἡδονὰσ ἡ σωφροσύνη καὶ ἡ ἀκολασία ἐστὶν ὧν καὶ τὰ λοιπὰ ζῷα κοινωνεῖ, ὅθεν ἀνδραποδώδεισ καὶ θηριώδεισ φαίνονται·
