3.692e-693a (tr. Trevor J. Saunders):
If it hadn't been for the joint
determination of the Athenians and the Spartans to resist the slavery that threatened them, we should have by now virtually a
complete mixture of the races — Greek with Greek, Greek with
barbarian, and barbarian with Greek. We can see a parallel in the nations
whom the Persians lord it over today: they have been split up and then
horribly jumbled together again into the scattered communities in which
they now live.
ἀλλ᾽ εἰ μὴ τό τε Ἀθηναίων καὶ τὸ Λακεδαιμονίων κοινῇ διανόημα
ἤμυνεν τὴν ἐπιοῦσαν δουλείαν, σχεδὸν ἂν ἤδη πάντ᾽ ἦν μεμειγμένα τὰ τῶν Ἑλλήνων γένη ἐν ἀλλήλοις, καὶ βάρβαρα ἐν Ἕλλησι καὶ Ἑλληνικὰ ἐν βαρβάροις, καθάπερ ὧν Πέρσαι τυραννοῦσι τὰ νῦν διαπεφορημένα καὶ συμπεφορημένα κακῶς ἐσπαρμένα κατοικεῖται.
