Plato, Meno 72e

ᾖ, ἐάντε ἐν ἀνδρὶ ἐάντε ἐν ἄλλῳ ὁτῳοῦν ᾖ; ἡ αὐτή μοι δοκεῖ ὑγίειά γε εἶναι καὶ ἀνδρὸς καὶ γυναικός. οὐκοῦν καὶ μέγεθος καὶ ἰσχύς; ἐάνπερ ἰσχυρὰ γυνὴ ᾖ, τῷ αὐτῷ εἴδει καὶ τῇ αὐτῇ ἰσχύϊ ἰσχυρὰ ἔσται; τὸ γὰρ τῇ αὐτῇ τοῦτο λέγω· οὐδὲν διαφέρει πρὸς τὸ ἰσχὺς εἶναι ἡ ἰσχύς, ἐάντε ἐν ἀνδρὶ ᾖ ἐάντε ἐν γυναικί. ἢ δοκεῖ τί σοι διαφέρειν; οὐκ ἔμοιγε.

in a man or in anyone else? I think that health is the same, both in man and in woman. Then is it not so with size and strength also? If a woman is strong, she will be strong by reason of the same form and the same strength; by the same I mean that strength does not differ as strength, whether it be in a man or in a woman. Or do you think there is any difference? I do not.
