Varro says also, concerning the generations of the gods, that the people have inclined to the poets rather than to the natural philosophers; and that therefore their forefathers—that is, the ancient Romans,— believed both in the sex and the generations of the gods, and settled their marriages; which certainly seems to have been done for no other cause except that it was the business of such men as were prudent and wise to deceive the people in matters of religion, and in that very thing not only to worship, but also to imitate the demons, whose greatest lust is to deceive. For just as the demons cannot possess any but those whom they have deceived with guile, so also men in princely office, not indeed being just, but like demons, have persuaded the people in the name of religion to receive as true those things which they themselves knew to be false; in this way, as it were, binding them up more firmly in civil society, so that they might in like manner possess them as subjects. But who that was weak and unlearned could escape the deceits of both the princes of the state and the demons?
