Can theology give to the mind the ineffable boon of conceiving that which no man is in a capacity to comprehend? Can it procure to its agents the marvellous faculty of having precise ideas of a god composed of so many contradictory qualities?

It is thus religion infatuates man from his infancy, fills him with vanity and fanaticism: if he has a heated imagination it drives him on to fury; if he has activity, it makes him a madman, who is frequently as cruel to himself, as he is dangerous and incommodious to others: if, on the contrary, he be phlegmatic or of a slothful habit, he becomes melancholy and is useless to society.

The unhappiness of people is due to their ignorance of nature.

If the ministers of the Church have often permitted nations to revolt for Heaven's cause, they never allowed them to revolt against real evils or known violencess. It is from Heaven that the chains have come to fetter the minds of mortals.

If experience be consulted, it will be found there is no action, however abominable, that has not received the applause of some people. Parricide - the sacrifice of children - robbery - usurpation - cruelty - intolerance - prostitution, have all in their turn been licensed actions, and have been deemed laudable and meritorious deeds with some nations of the earth. Above all, Religion has consecrated the most unreasonable, the most revolting customs.

People have suffered and become insane for centuries by the thought of eternal punishment after death. Wouldn't it be better to depend on blind matter... than a god who puts out traps for people, invites them to sin, and allows them to sin and commit crimes he could prevent. Only to finally get the barbarian pleasure to punish them in an excessive way, of no use for himself, without them changing their ways and without their example preventing others from committing crimes.

If the ignorance of nature gave birth to gods, the knowledge of nature is calculated to destroy them.
