Plato, Laws 900d

δέ, ἢ τῶν μεγέθει διαφερόντων. ἤκουε γάρ που καὶ παρῆν τοῖς νυνδὴ λεγομένοις, ὡς ἀγαθοί γε ὄντες πᾶσαν ἀρετὴν τὴν τῶν πάντων ἐπιμέλειαν οἰκειοτάτην αὑτῶν οὖσαν κέκτηνται. καὶ σφόδρα γε ἐπήκουεν. τὸ μετὰ τοῦτο τοίνυν κοινῇ συνεξεταζόντων τίνα λέγοντες ἀρετὴν αὐτῶν ὁμολογοῦμεν αὐτοὺς ἀγαθοὺς εἶναι. φέρε, τὸ σωφρονεῖν νοῦν τε κεκτῆσθαί φαμεν ἀρετῆς, τὰ δʼ ἐναντία κακίας; φαμέν.

he was present at our recent argument, and heard that the gods, being good with all goodness, possess such care of the whole as is most proper to themselves. Most certainly he heard that. Let us join next in enquiring what is that goodness of theirs in respect of which we agree that they are good. Come now, do we say that prudence and the possession of reason are parts of goodness, and the opposites of these of badness? We do say so. And further, that courage is part of goodness, and cowardice of badness? Certainly.
