For the generality of men nothing renders an argument more convincing than fear. In consequence of this fact, theologians tell us that the safest side must be taken; that nothing is more criminal than incredulity; that G.o.d will punish without mercy all those who have the temerity to doubt His existence; that His severity is just; since it is only madness or perversity which questions the existence of an angry monarch who revenges himself cruelly upon atheists. If we examine these menaces calmly, we shall find that they a.s.sume always the thing in question. They must commence by proving to our satisfaction the existence of a G.o.d, before telling us that it is safer to believe, and that it is horrible to doubt or to deny it. Then they must prove that it is possible for a just G.o.d to punish men cruelly for having been in a state of madness, which prevented them from believing in the existence of a being whom their enlightened reason could not comprehend. In a word, they must prove that a G.o.d that is said to be full of equity, could punish beyond measure the invincible and necessary ignorance of man, caused by his relation to the divine essence. Is not the theologians" manner of reasoning very singular? They create phantoms, they fill them with contradictions, and finally a.s.sure us that the safest way is not to doubt the existence of those phantoms, which they have themselves invented. By following out this method, there is no absurdity which it would not be safer to believe than not to believe.
All children are atheists--they have no idea of G.o.d; are they, then, criminal on account of this ignorance? At what age do they begin to be obliged to believe in G.o.d? It is, you say, at the age of reason. At what time does this age begin? Besides, if the most profound theologians lose themselves in the divine essence, which they boast of not comprehending, what ideas can common people have?--women, mechanics, and, in short, those who compose the ma.s.s of the human race?
x.x.xI.--THE BELIEF IN G.o.d IS NOTHING BUT A MECHANICAL HABITUDE OF CHILDHOOD.
Men believe in G.o.d only upon the word of those who have no more idea of Him than they themselves. Our nurses are our first theologians; they talk to children of G.o.d as they talk to them of were-wolfs; they teach them from the most tender age to join the hands mechanically. Have the nurses clearer notions of G.o.d than the children, whom they compel to pray to Him?
x.x.xII.--IT IS A PREJUDICE WHICH HAS BEEN HANDED FROM FATHER TO CHILDREN.
Religion is handed down from fathers to children as the property of a family with the burdens. Very few people in the world would have a G.o.d if care had not been taken to give them one. Each one receives from his parents and his instructors the G.o.d which they themselves have received from theirs; only, according to his own temperament, each one arranges, modifies, and paints Him agreeably to his taste.
x.x.xIII.--ORIGIN OF PREJUDICES.
The brain of man is, especially in infancy, like a soft wax, ready to receive all the impressions we wish to make on it; education furnishes nearly all his opinions, at a period when he is incapable of judging for himself. We believe that the ideas, true or false, which at a tender age were forced into our heads, were received from nature at our birth; and this persuasion is one of the greatest sources of our errors.
x.x.xIV.--HOW THEY TAKE ROOT AND SPREAD.
Prejudice tends to confirm in us the opinions of those who are charged with our instruction. We believe them more skillful than we are; we suppose them thoroughly convinced themselves of the things they teach us. We have the greatest confidence in them. After the care they have taken of us when we were unable to a.s.sist ourselves, we judge them incapable of deceiving us. These are the motives which make us adopt a thousand errors without other foundation than the dangerous word of those who have educated us; even the being forbidden to reason upon what they tell us, does not diminish our confidence, but contributes often to increase our respect for their opinions.
x.x.xV.--MEN WOULD NEVER HAVE BELIEVED IN THE PRINCIPLES OF MODERN THEOLOGY IF THEY HAD NOT BEEN TAUGHT AT AN AGE WHEN THEY WERE INCAPABLE OF REASONING.
The instructors of the human race act very prudently in teaching men their religious principles before they are able to distinguish the true from the false, or the left hand from the right. It would be as difficult to tame the spirit of a man forty years old with the extravagant notions which are given us of Divinity, as to banish these notions from the head of a man who has imbibed them since his tenderest infancy.
x.x.xVI.--THE WONDERS OF NATURE DO NOT PROVE THE EXISTENCE OF G.o.d.
We are a.s.sured that the wonders of nature are sufficient to a belief in the existence of a G.o.d, and to convince us fully of this important truth. But how many persons are there in this world who have the leisure, the capacity, the necessary taste, to contemplate nature and to meditate upon its progress? The majority of men pay no attention to it.
A peasant is not at all moved by the beauty of the sun, which he sees every day. The sailor is not surprised by the regular movements of the ocean; he will draw from them no theological inductions. The phenomena of nature do not prove the existence of a G.o.d, except to a few forewarned men, to whom has been shown in advance the finger of G.o.d in all the objects whose mechanism could embarra.s.s them. The unprejudiced philosopher sees nothing in the wonders of nature but permanent and invariable law; nothing but the necessary effects of different combinations of diversified substance.
x.x.xVII.--THE WONDERS OF NATURE EXPLAIN THEMSELVES BY NATURAL CAUSES.
Is there anything more surprising than the logic of so many profound doctors, who, instead of acknowledging the little light they have upon natural agencies, seek outside of nature--that is to say, in imaginary regions--an agent less understood than this nature, of which they can at least form some idea? To say that G.o.d is the author of the phenomena that we see, is it not attributing them to an occult cause? What is G.o.d?
What is a spirit? They are causes of which we have no idea. Sages! study nature and her laws; and when you can from them unravel the action of natural causes, do not go in search of supernatural causes, which, very far from enlightening your ideas, will but entangle them more and more and make it impossible for you to understand yourselves.
x.x.xVIII--CONTINUATION.
Nature, you say, is totally inexplicable without a G.o.d; that is to say, in order to explain what you understand so little, you need a cause which you do not understand at all. You pretend to make clear that which is obscure, by magnifying its obscurity. You think you have untied a knot by multiplying knots. Enthusiastic philosophers, in order to prove to us the existence of a G.o.d, you copy complete treatises on botany; you enter into minute details of the parts of the human body; you ascend into the air to contemplate the revolutions of the stars; you return then to earth to admire the course of the waters; you fly into ecstasies over b.u.t.terflies, insects, polyps, organized atoms, in which you think to find the greatness of your G.o.d; all these things will not prove the existence of this G.o.d; they will only prove that you have not the ideas which you should have of the immense variety of causes and effects that can produce the infinitely diversified combinations, of which the universe is the a.s.semblage. This will prove that you ignore nature, that you have no idea of her resources when you judge her incapable of producing a mult.i.tude of forms and beings, of which your eyes, even by the aid of the microscope, see but the least part; finally, this will prove, that not being able to know the sensible and comprehensible agents, you find it easier to have recourse to a word, by which you designate an agent, of whom it will always be impossible for you to form any true idea.
x.x.xIX.--THE WORLD HAS NOT BEEN CREATED, AND MATTER MOVES BY ITSELF.
They tell us gravely that there is no effect without a cause; they repeat to us very often that the world did not create itself. But the universe is a cause, not an effect; it is not a work, has not been made, because it was impossible that it should be made. The world has always been, its existence is necessary. It is the cause of itself. Nature, whose essence is visibly acting and producing, in order to fulfill her functions, as we see she does, needs no invisible motor far more unknown than herself. Matter moves by its own energy, by the necessary result of its heterogeneity; the diversity of its movements or of its ways of acting, const.i.tute only the diversity of substances; we distinguish one being from another but by the diversity of the impressions or movements which they communicate to our organs.
XL.--CONTINUATION.
You see that everything in nature is in a state of activity, and you pretend that nature of itself is dead and without energy! You believe that all this, acting of itself, has need of a motor! Well! who is this motor? It is a spirit, that is to say, an absolutely incomprehensible and contradictory being. Conclude then, I say to you, that matter acts of itself, and cease to reason about your spiritual motor, which has nothing that is necessary to put it into motion. Return from your useless excursions; come down from an imaginary into a real world; take hold of second causes; leave to theologians their "First Cause," of which nature has no need in order to produce all the effects which you see.
XLI.--OTHER PROOFS THAT MOTION IS IN THE ESSENCE OF MATTER, AND THAT IT IS NOT NECESSARY TO SUPPOSE A SPIRITUAL MOTOR.
It is but by the diversity of impressions or of effects which substances or bodies make upon us, that we feel them, that we have perceptions and ideas of them, that we distinguish them one from another, that we a.s.sign to them peculiarities. Moreover, in order to perceive or to feel an object, this object must act upon our organs; this object can not act upon us without exciting some motion in us; it can not produce any motion in us if it is not itself in motion. As soon as I see an object, my eyes must be struck by it; I can not conceive of light and of vision without a motion in the luminous, extended, and colored body which communicates itself to my eye, or which acts upon my retina. As soon as I smell a body, my olfactory nerve must be irritated or put into motion by the parts exhaled from an odorous body. As soon as I hear a sound, the tympanum of my ear must be struck by the air put in motion by a sonorous body, which could not act if it was not moved of itself. From which it follows, evidently, that without motion I can neither feel, see, distinguish, compare, nor judge the body, nor even occupy my thought with any matter whatever. It is said in the schools, that the essence of a being is that from which flow all the properties of that being. Now then, it is evident that all the properties of bodies or of substances of which we have ideas, are due to the motion which alone informs us of their existence, and gives us the first conceptions of it.
I can not be informed or a.s.sured of my own existence but by the motions which I experience within myself. I am compelled to conclude that motion is as essential to matter as its extension, and that it can not be conceived of without it. If one persists in caviling about the evidences which prove to us that motion is an essential property of matter, he must at least acknowledge that substances which seemed dead or deprived of all energy, take motion of themselves as soon as they are brought within the proper distance to act upon each other. Pyrophorus, 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 G.o.d.
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 embarra.s.sed 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 G.o.d, 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; from this I conclude that human intelligence depends upon a certain disposition of the material organs of the body, and that, because man is an intelligent being, it is not well to conclude that G.o.d must be an intelligent being, any more than because man is material, we are compelled to conclude that G.o.d is material. The intelligence of man no more proves the intelligence of G.o.d than the malice of men proves the malice of this G.o.d, of whom they pretend that man is the work. In whatever way theology is taken, G.o.d will always be a cause contradicted by its effects, or of whom it is impossible to judge by His works. We shall always see evil, imperfections, and follies resulting from a cause claimed to be full of goodness, of perfections, and of wisdom.
XLIII.--HOWEVER, NEITHER MAN NOR THE UNIVERSE IS THE EFFECT OF CHANCE.
Then you will say that intelligent man and even the universe and all it encloses, are the effects of chance. No, I answer, the universe is not an effect; it is the cause of all effects; all the beings it embraces are the necessary effects of this cause which sometimes shows to us its manner of acting, out which often hides from us its way. Men may use the word "chance" to cover their ignorance of the true causes; nevertheless, although they may ignore them, these causes act, but by certain laws.
