Plato, Laws 899b

ναί, τόν γέ που μὴ ἐπὶ τὸ ἔσχατον ἀφιγμένον ἀνοίας. ἄστρων δὴ πέρι πάντων καὶ σελήνης, ἐνιαυτῶν τε καὶ μηνῶν καὶ πασῶν ὡρῶν πέρι, τίνα ἄλλον λόγον ἐροῦμεν ἢ τὸν αὐτὸν τοῦτον, ὡς ἐπειδὴ ψυχὴ μὲν ἢ ψυχαὶ πάντων τούτων αἴτιαι ἐφάνησαν, ἀγαθαὶ δὲ πᾶσαν ἀρετήν, θεοὺς αὐτὰς εἶναι φήσομεν, εἴτε ἐν σώμασιν ἐνοῦσαι, ζῷα ὄντα, κοσμοῦσιν πάντα οὐρανόν, εἴτε ὅπῃ τε καὶ ὅπως; ἔσθʼ ὅστις ταῦτα ὁμολογῶν ὑπομενεῖ μὴ θεῶν εἶναι πλήρη πάντα;

Yes; everyone at least who has not reached the uttermost verge of folly. Concerning all the stars and the moon, and concerning the years and months and all seasons, what other account shall we give than this very same,—namely, that, inasmuch as it has been shown that they are all caused by one or more souls, which are good also with all goodness, we shall declare these souls to be gods, whether it be that they order the whole heaven by residing in bodies, as living creatures, or whatever the mode and method? Is there any man that agrees with this view who will stand hearing it denied that all things are full of gods?
