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.

What, indeed, is an atheist? He is one who destroys delusions which are harmful to humanity in order to lead men back to nature, to reality, to reason. He is a thinker who, having reflected on the nature of matter, its energy, properties and ways of acting, has no need of idealized powers or imaginary intelligences to explain the phenomena of the universe and the operations of nature.

In Nature nothing; is mean or contemptible, and it is only pride, originating in a false idea of our superiority, which causes our contempt for some of her productions. In the eyes of Nature, however, the oyster that vegetates at the bottom of the sea is as dear and perfect as the proud biped who devours it.

Many men without morals have attacked religion because it was contrary to their inclinations. Many wise men have despised it because it seemed to them ridiculous. Many persons have regarded it with indifference, because they have never felt its true disadvantages. But it is as a citizen that I attack it, because it seems to me harmful to the happiness of the state, hostile to the march of the mind of man, and contrary to sound morality, from which the interests of state policy can never be separated.

The universe, that vast assemblage of every thing that exists, presents only matter and motion: the whole offers to our contemplation, nothing but an immense, an uninterrupted succession of causes and effects.

Nature, you say, is totally inexplicable without a God. That is to say, to explain what you understand very little, you have need of a cause which you understand not at all.

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