Men always fool themselves when they give up experience for systems born of the imagination. Man is the work of nature, he exists in nature, he is subject to its laws, he can not break free, he can not leave even in thought; it is in vain that his spirit wants to soar beyond the bounds of the visible world, he is always forced to return.

Religion has ever filled the mind of man with darkness, and kept him in ignorance of his real duties and true interests. It is by dispelling the clouds and phantoms of religion, that we shall discover truth, morality and reason. Religion diverts us from the causes of evils, and from these remedies which nature advocates, far from curing; it only aggravates, perpetuates and multiplies them.

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.

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.

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

Suns are extinguished or become corrupted, planets perish and scatter across the wastes of the sky; other suns are kindled, new planets formed to make their revolutions or describe new orbits, and man, an infinitely minute part of a globe which itself is only an imperceptible point in the immense whole, believes that the universe is made for himself.

God, we are told, is willing to render himself inconsistent and ridiculous, to confound the curiosity of those whom, we are at the same time informed, he desires to enlighten by his special grace. What must we think of a revelation which, far from teaching us any thing, is calculated to darken and puzzle the clearest ideas?
