De Superstitione

Ignorance and blindness in regard to the gods divides itself at the very beginning into two streams, of which the one produces in hardened characters, as it were in stubborn soils, atheism, and the other in tender characters, as in moist soils, produces superstition. Every false judgement, and especially concerning these matters, is a mischievous thing; but where emotion also enters, it is most mischievous. For every emotion is likely to be a delusion that rankles; and just as dislocations of the joints accompanied by lacerations are hardest to deal with, so also is it with derangements of the soul accompanied by emotion.

A man thinks that in the beginning the universe was created out of atoms and void. His assumption is false, but it causes no sore, no throbbing, no agitating pain.

A man assumes that wealth is the greatest good. This falsehood contains venom, it feeds upon his soul, distracts him, does not allow him to sleep, fills him with stinging desires, pushes him over precipices, chokes him, and takes from him his freedom of speech.
