Whence comes man? What is his origin? Did the first man spring, ready formed, from the dust of the earth? Man appears, like all other beings, a production of nature. Whence came the first stones, the first trees, the first lions, the first elephants, the first ants, the first acorns? We are incessantly told to acknowledge and revere the hand of God, of an infinitely wise, intelligent and powerful maker, in so wonderful a work as the human machine. I readily confess, that the human machine appears to me surprising. But as man exists in nature, I am not authorized to say that his formation, is above the power of nature. But I can much less conceive of this formation, when to explain it, I am told, that a pure spirit, who has neither eyes, feet, hands, head, lungs, mouth nor breath, made man by taking a little clay, and breathing upon it.

We laugh at the savage inhabitants of Paraguay, for calling themselves the descendants of the moon. The divines of Europe call themselves the descendants, or the creation, of a pure spirit. Is this pretension any more rational? Man is intelligent; thence it is inferred, that he can be the work only of an intelligent being, and not of a nature, which is void of intelligence. Although nothing is more rare, than to see man make use of this intelligence, of which he seems so proud, I will grant that he is intelligent, that his wants develop this faculty, that society especially contributes to cultivate it. But I see nothing in the human machine, and in the intelligence with which it is endued, that announces very precisely the infinite intelligence of the maker to whom it is ascribed. I see that this admirable machine is liable to be deranged; I see, that his wonderful intelligence is then disordered, and sometimes totally disappears; I infer, that human intelligence depends upon a certain disposition of the material organs of the body, and that we cannot infer the intelligence of God, any more from the intelligence of man, than from his materiality. All that we can infer from it, is, that God is material. The intelligence of man no more proves the intelligence of God, than the malice of man proves the malice of that God, who is the pretended maker of man. In spite of all the arguments of divines, God will always be a cause contradicted by its effects, or of which it is impossible to judge by its works. We shall always see evil, imperfection and folly result from such a cause, that is said to be full of goodness, perfection and wisdom.
