rophorus, when
enclosed in a bottle or deprived of contact with the air, can not take
fire by itself, but it burns as soon as exposed to the air. Flour and
water cause fermentation as soon as they are mixed. Thus dead substances
engender motion of themselves. Matter has then the power to move itself,
and nature, in order to act, does not need a motor whose essence would
hinder its activity.

XLII.--THE EXISTENCE OF MAN DOES NOT PROVE THAT OF GOD.

Whence comes man? What is his origin? Is he the result of the fortuitous
meeting of atoms? Was the first man formed of the dust of the earth? I
do not know! Man appears to me to be a production of nature like all
others she embraces. I should be just as much embarrassed to tell you
whence came the first stones, the first trees, the first elephants, the
first ants, the first acorns, as to explain the origin of the human
species. Recognize, we are told, the hand of God, of an infinitely
intelligent and powerful workman, in a work so wonderful as the human
machine. I would admit without question that the human machine appears
to me surprising; but since man exists in nature, I do not believe it
right to say that his formation is beyond the forces of nature. I will
add, that I could conceive far less of the formation of the human
machine, when to explain it to me they tell me that a pure spirit, who
has neither eyes, nor feet, nor hands, nor head, nor lungs, nor mouth,
nor breath, has made man by taking a little dust and blowing upon it.
The savage inhabitants of Paraguay pretend to be descended from the
moon, and appear to us as simpletons; the theologians of Europe pretend
to be descended from a pure spirit. Is this pretension more sensible?

Man is intelligent, hence it is concluded that he must be the work of an
intelligent being, and not of a nature devoid of intelligence. Although
nothing is more rare than to see man use this intelligence, of which he
appears so proud, I will admit that he is intelligent, that his
necessities develop in him this faculty, that the society of other men
contributes especially to cultivate it. But in the human machine and in
the intelligence with which it is endowed, I see nothing that shows in a
precise manner the infinite intelligence of the workman who has the
honor of making it. I see that this admirable machine is subject to
derangement; that at that time this wonderful intelligence is
disordered, and sometimes totally disappears; f
