Plato, Laws 898c

νῦν δὴ χαλεπὸν οὐδὲν ἔτι διαρρήδην εἰπεῖν ὡς, ἐπειδὴ ψυχὴ μέν ἐστιν ἡ περιάγουσα ἡμῖν πάντα, τὴν δὲ οὐρανοῦ περιφορὰν ἐξ ἀνάγκης περιάγειν φατέον ἐπιμελουμένην καὶ κοσμοῦσαν ἤτοι τὴν ἀρίστην ψυχὴν ἢ τὴν ἐναντίαν. ὦ ξένε, ἀλλὰ ἔκ γε τῶν νῦν εἰρημένων οὐδʼ ὅσιον ἄλλως λέγειν ἢ πᾶσαν ἀρετὴν ἔχουσαν ψυχὴν μίαν ἢ πλείους περιάγειν αὐτά. κάλλιστα, ὦ Κλεινία, ὑπήκουσας τοῖς λόγοις· τόδε

or system or rule—will not this motion be akin to absolute unreason? It will, in very truth. So now there is no longer any difficulty in stating expressly that, inasmuch as soul is what we find driving everything round, we must affirm that this circumference of Heaven is of necessity driven round under the care and ordering of either the best soul or its opposite. But, Stranger, judging by what has now been said, it is actually impious to make any other assertion than that these things are driven round by one or more souls endowed with all goodness. You have attended to our argument admirably, Clinias.
