Savage and furious nations, perpetually at war, adore, under diverse names, some God, conformable to their ideas, that is to say, cruel, carnivorous, selfish, blood-thirsty.

The Jehovah of the Jews is a suspicious tyrant, who breathes nothing but blood, murder, and carnage, and who demands that they should nourish him with the vapours of animals. The Jupiter of the Pagans is a lascivious monster. The Moloch of the Phoenicians is a cannibal. The pure mind of the Christians resolved, in order to appease his fury, to crucify his own son. The savage god of the Mexicans cannot be satisfied without thousands of mortals which are immolated to his sanguinary appetite.

If we go back to the beginnings of things, we shall always find that ignorance and fear created the gods; that imagination, rapture and deception embellished them; that weakness worships them; that custom spares them; and that tyranny favors them in order to profit from the blindness of men.

The source of man's unhappiness is his ignorance of Nature.

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.

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

It is thus superstition infatuates man from his infancy, fills him with vanity, and enslaves him with fanaticism.
