οἱ μέν που κόσμιοι τὸ σφέτερον αὐτῶν ἦθος ζητοῦσι, καὶ κατὰ δύναμιν γαμοῦσί τε παρὰ τούτων καὶ τὰς (310d) ἐκδιδομένας παρ᾽ αὑτῶν εἰς τούτους ἐκπέμπουσι πάλιν: ὡς δ᾽ αὕτως τὸ περὶ τὴν ἀνδρείαν γένος δρᾷ, τὴν αὑτοῦ μεταδιῶκον φύσιν, δέον ποιεῖν ἀμφότερα τὰ γένη τούτων τοὐναντίον ἅπαν.
eng tr. Jowett 1817-1893STRANGER:
The quiet orderly class seek for natures like their own, and as far as they can they marry and give in marriage exclusively in this class, and the courageous do the same; they seek natures like their own, whereas they should both do precisely the opposite.
