Plato, Laws 860b

τὸν ἱερόσυλόν που ἐτίθεμεν δικαίως ἂν ἀποθνῄσκειν καὶ τὸν τῶν εὖ κειμένων νόμων πολέμιον, καὶ μέλλοντες δὴ νόμιμα τοιαῦτα τιθέναι πάμπολλα ἐπέσχομεν, ἰδόντες ὡς ταῦτα ἐστὶν μὲν ἄπειρα παθήματα πλήθει καὶ μεγέθεσιν, δικαιότατα δὲ πάντων παθημάτων καὶ συμπάντων αἴσχιστα. μῶν οὐχ οὕτως ἡμῖν τά τε δίκαια καὶ τὰ καλὰ τοτὲ μὲν ὡς ταὐτὰ σύμπαντα, τοτὲ δὲ ὡς ἐναντιώτατα φανεῖται; κινδυνεύει.

We laid it down that it is just to put to death the temple-robber and the enemy of the rightly-enacted laws; and then, when we were minded to enact a host of similar rules, we held our hand, since we perceived that such rules involve passions infinite both in number and in magnitude, and that, although they are eminently just, they are also eminently unseemly. Thus the just and the beautiful will seem to us at one moment wholly identical, at another, utterly opposed, will they not? I am afraid so.
