Plato, Laws 945d

οἴχεσθαι πολιτείαν. ἂν μὲν γὰρ οἱ τοὺς ἄρχοντας ἐξευθύνοντες βελτίους ὦσιν ἐκείνων, καὶ τοῦτʼ ἐν δίκῃ ἀμέμπτῳ τε καὶ ἀμέμπτως, ἡ πᾶσα οὕτω θάλλει τε καὶ εὐδαιμονεῖ χώρα καὶ πόλις· ἐὰν δʼ ἄλλως τὰ περὶ τὰς εὐθύνας τῶν ἀρχόντων γίγνηται, τότε λυθείσης τῆς τὰ πάντα πολιτεύματα συνεχούσης εἰς ἓν δίκης, ταύτῃ πᾶσα ἀρχὴ διεσπάσθη χωρὶς ἑτέρα ἀπʼ ἄλλης, καὶ οὐκ εἰς τὸ αὐτὸ ἔτι νεύουσαι,

For if those who act as examiners of the magistrates are better men than they, and if they act blamelessly with blameless justice, then the whole of the State and country flourishes and is happy; but if the examination of the magistrates is carried out otherwise, then the bond of justice which binds all political elements into one is dissolved, and in consequence every office is torn apart from every other, and they no longer tend all to the same end; and thus out of one State they make many, and by filling it with civil strife they speedily bring it to ruin.
