Plato, Laws 627a

ἐστί, πότερα φῶμεν οἰκίαν τε καὶ κώμην καὶ πόλιν ἔχειν ταὐτὸν τοῦτο ἐν αὑταῖς ἢ μὴ φῶμεν; τὸ κρείττω τε ἑαυτῆς εἶναι λέγεις τινά, τὴν δʼ ἥττω; ναί. καὶ τοῦτο ὀρθῶς ἤρου· πάνυ γὰρ ἔστι καὶ σφόδρα τὸ τοιοῦτον, οὐχ ἥκιστα ἐν ταῖς πόλεσιν. ἐν ὁπόσαις μὲν γὰρ οἱ ἀμείνονες νικῶσιν τὸ πλῆθος καὶ τοὺς χείρους, ὀρθῶς ἂν αὕτη κρείττων τε ἑαυτῆς λέγοιθʼ ἡ πόλις, ἐπαινοῖτό τε ἂν δικαιότατα τῇ τοιαύτῃ νίκῃ· τοὐναντίον δέ, ὅπου τἀναντία.

and partly inferior, are we to affirm that the same condition of things exists in house and village and State, or are we to deny it? Do you mean the condition of being partly self-superior and partly self-inferior? Yes. That, too, is a proper question; for such a condition does most certainly exist, and in States above all. Every State in which the better class is victorious over the populace and the lower classes would rightly be termed self-superior, and would be praised most justly for a victory of this kind; and conversely, when the reverse is the case.
