The Epistle to Diogentus

Come then, clear yourself of all the prejudice[*](Discussion of the Gods of the heathen) which occupies your mind, and throw aside the custom which deceives you, and become as it were

a new man from the beginning, as one, as you yourself also admitted, who is about to listen to a new story. Look, not only with your eyes, but also with your intelligence, what substance or form they chance to have whom you call gods and regard as such.
