Plato, Laws 897c

καὶ ἀρετῆς πλῆρες, ἢ τὸ μηδέτερα κεκτημένον; βούλεσθε οὖν πρὸς ταῦτα ὧδε ἀποκρινώμεθα; πῶς; εἰ μέν, ὦ θαυμάσιε, φῶμεν, ἡ σύμπασα οὐρανοῦ ὁδὸς ἅμα καὶ φορὰ καὶ τῶν ἐν αὐτῷ ὄντων ἁπάντων νοῦ κινήσει καὶ περιφορᾷ καὶ λογισμοῖς ὁμοίαν φύσιν ἔχει καὶ συγγενῶς ἔρχεται, δῆλον ὡς τὴν ἀρίστην ψυχὴν φατέον ἐπιμελεῖσθαι τοῦ κόσμου παντὸς καὶ ἄγειν αὐτὸν τὴν τοιαύτην ὁδὸν ἐκείνην. ὀρθῶς.

has neither quality? To this shall we make reply as follows? How? If, my good sir, we are to assert that the whole course and motion of Heaven and of all it contains have a motion like to the motion and revolution and reckonings of reason, and proceed in a kindred manner, then clearly we must assert that the best soul regulates the whole cosmos and drives it on its course, which is of the kind described. You are right.
