Alexander Aphrod. Quaest. IV 1 p. 119, 23 Bruns. πῶς γὰρ οὐκ ἀπεμφαῖνον τὸ ὁμοῦ μὲν λέγειν ἡμᾶς ὑπὸ τῆς φύσεως πρὸς τοῦτο (scil. τὸ ζῆν) οἰκειοῦσθαι καὶ τῆς ἑαυτῶν σωτηρίας χάριν ποιεῖν πάντα, ὁμοῦ δὲ μὴ λέγειν [ἡμᾶς] ὡς πρὸς ἀγαθὸν αὐτὸ τὴν φύσιν ἡμᾶς οἰκειοῦν.
Cf. ibid. p. 118, 23εἰ τὸ εὖ πλεῖν ἀγαθόν, τὸ δὲ κακῶς κακόν, τὸ πλεῖν οὔτε ἀγαθὸν οὔτε κακόν· καὶ εἰ τὸ εὖ ζῆν ἀγαθόν, τὸ δὲ κακῶς κακόν, τὸ ζῆν οὔτ’ ἀγαθὸν οὔτε κακόν
(Addit ipse Alexander: ἢ οὐκ ἀληθὲς τὸ τὰς δυνάμεις τῶν ἀντικειμένων ἀδιαφόρους εἶναι καὶ μέσας;).
