Part 8 (1/2)

The solar system has been known a long while; it is taught in the humblest schools, and no longer surprises any one. But those who found out, after long efforts, what we learn without trouble, the discoverers, reckoned their discoveries very surprising. Kepler, one of the founders of modern astronomy, in the book to which he consigned his immortal discoveries, exclaims:[97] ”The wisdom of the Lord is infinite, as are also His glory and His power. Ye heavens! sing His praises. Sun, moon, and planets, glorify Him in your ineffable language! Praise Him, celestial harmonies, and all ye who can comprehend them! And thou, my soul, praise thy Creator! It is by Him, and in Him, that all exists.

What we know not is contained in Him as well as our vain science. To Him be praise, honor, and glory for ever and ever!” These words, Gentlemen, have not been copied from a book of the Church; they are read in a work which, as all allow, is one of the foundations of modern science.

I pa.s.s on to another example, and I continue to keep you in good and high company. Newton set forth his discoveries in a large volume all bristling with figures and calculations.[98] The work of the mathematician ended, the author rises, by the consideration of the mutual interchange of the light of all the stars, to the idea of the unity of the creation; then he adds, and it is the conclusion of his entire work: ”The Master of the heavens governs all things, not as being the soul of the world, but as being the Sovereign of the universe. It is on account of His sovereignty that we call Him the Sovereign G.o.d. He governs all things, those which are, and those which may be. He is the one G.o.d, and the same G.o.d, everywhere and always. We admire Him because of His perfections, we reverence and adore Him because of His sovereignty. A G.o.d without sovereignty, without providence, and without object in His works, would be only destiny or nature. Now, from a blind metaphysical necessity, everywhere and always the same, could arise no variety; all that diversity of created things according to places and times (which const.i.tutes the order and life of the universe) could only have been produced by the thought and will of a Being who is _the Being_, existing by Himself, and necessarily.”

Here, Sirs, are n.o.ble thoughts, expressed in n.o.ble style. I recommend you to read throughout the pages from which I have quoted a few fragments. Let us now a.n.a.lyze the ideas of this great astronomer as thus expounded. We may note these three affirmations:

1. The universe displays an admirable order which reveals the wisdom of the Power which governs it.

2. The universe lives; it is not fixed, and its variations suppose an intelligent Power which directs it.

3. The variable existence of the universe shows that it is not necessary; it must have its cause in a Being who is _the_ Being, necessarily, by His proper nature.

Such are the views of Newton. Examine this course of thought, and see if it is not natural. Observation reveals to us facts. Facts in themselves, isolated facts, are nothing for the mind; but in the facts of nature, human reason discovers an order, and in that order it recognizes its own proper laws. To keep within the domain of astronomy--there is harmony between our mind and the course of the stars. If you have any doubt about this, I appeal to the almanac. We there find it stated that in such a month, on such a day, at such an hour, there will be an eclipse of the sun or of the moon. How comes the editor of the almanac to know that? He has learnt it from the savants who have succeeded in explaining the phenomena of the skies. The savant therefore can in his study meet with the intelligence which directs the universe. If he makes no mistake in his calculations, the eclipse begins at the precise hour which he has indicated. If the eclipse did not take place at the instant foreseen, no one would suspect Nature of not following the course prescribed by the directing intelligence; the inference would be that there had been a fault in observation, or an error of figures on the part of the astronomer.

When science, then, does its part well, the mind of man encounters another mind which is governing the world and maintaining it in order.

The special science of nature stops there, as we shall explain further on; but this is not all that man requires, when he makes use of all his faculties. All is pa.s.sing and changing in the domain of experience; and reason seeks instinctively the cause of changeable facts in an unchangeable Being, the cause of transient phenomena in an eternal Being. Nature, therefore, does not suffice to account to us for itself.

It demands a power to direct it, an intelligence to regulate it; an absolute eternal Being as its cause. This is what reason imperatively requires; and when we possess the idea of G.o.d, nature reveals to us His power and His wisdom.

This is an old argument, and they call it commonplace. It is commonplace, in fact; it has appeared over and over again in the discourses of Socrates, in the writings of Galen, of Kepler, of Newton, of Linnaeus. Yes, this argument has fallen so low as to be public property, if we can say that truth falls when it s.h.i.+nes with a splendor vivid enough to enlighten the ma.s.ses. If I desired to bring together here the testimony of all the savants who have seen G.o.d in nature, the song of all the poets who have celebrated the glory of the Eternal as manifested by the creation, the enumeration would be long, and I should soon tire out your patience. You can understand therefore that if there are, as the misanthrope Rousseau says there are, philosophers who hold in such contempt vulgar opinions that they prefer error of their own discovery to truth found out by other people, then the ancient argument, which infers the wisdom of the Creator from the order of the creation, must be the object of but small esteem with them. Still I for my part take this old argument for a good one, and I mean to defend it.

Nature is verily and indeed a marvel placed before the observation of our minds. The growth of a blade of gra.s.s, the habits of an ant, contain for an attentive observer prodigies of wisdom. A drop of dew reflecting the beams of morning, the play of light among the leaves of a tree, reveal to the poet and the artist treasures of poetry. But too often, blinded by habit, we are unable to see; and when our mind is asleep, it seems to us that the universe slumbers. A sudden flash of light can sometimes arouse us from this lethargy. If science all at once delivers up to us some one of those grand laws which reveal in thousands of phenomena the traces of one and the same mind, the astonishment of our intellect excites in our soul an emotion of adoration. When the first rays of morning light up with a pure brightness the lofty summits of our Alps; when the sun at his setting stretches a path of fire along the waters of our lake, who does not feel impelled to render glory to the supreme Artist? When dark cold fogs rest upon our valleys at the decline of autumn, it only needs sometimes to climb the mountain-side, in order to issue all at once from the gloomy region, and see the chain of high peaks, resplendent with light, mark themselves out upon a sky of incomparable blue. Often have I given myself the delight of this grand spectacle, and always at such a time my heart has uttered spontaneously from its depths that hymn of adoration:

Tout l'univers est plein de sa magnificence.

Qu'on l'adore, ce Dieu, qu'on l'invoque a jamais![99]

Such is, in the presence of nature, the spontaneous movement of the heart and of the reason. But a false wisdom obscures these clear verities by clouds of sophisms. When your heart feels impelled to render glory to G.o.d, there is danger lest importunate thoughts rise in your mind and counteract the impulse of your adoration. Perhaps you have heard it said, perhaps you have read, that the accents of spiritual song, those echoes, growing ever weaker, of by-gone ages, are no longer heard by a mind enlightened by modern science. I should wish to deliver you from this painful doubt. I should wish to protect you from the fascinations of a false science. I should wish that in the view of nature, even those who have as yet no wish to adore, with St. Paul, Him whose invisible perfections are clearly seen when we contemplate His works, may at least feel themselves free to admire, with Socrates, ”the supreme G.o.d who maintains the works of creation in the flower of youth and in a vigor ever new.” Let us examine a few of the prejudices which it is sought to disseminate, in order to deprive of their force the reasonings of Newton, and to turn us from the opinions of Kepler.

It is said that science leads away from G.o.d, and that faith continues to be the lot only of the ignorant. Listen on this head first of all to the Italian Franchi. ”The cla.s.s of society in which infidels and sceptics especially abound is that of savants and men of letters,--men, in short, who have gone through studies, in the course of which they have certainly become acquainted with the famous demonstrations of the existence of G.o.d. But no sooner have they examined them with their own eyes, and submitted them to the criterion of their own judgment, than these demonstrations no longer demonstrate anything; these reasonings turn out to be only paralogisms.”[100] Here we have the thesis in its general form: to become an infidel or a sceptic, it is enough to be a well educated man. The German Buchner will now show us the application of this notion to the special study of nature. ”At this day, our hardest laborers in the sciences, our most indefatigable students of nature, profess materialistic sentiments.”[101] The same tendencies are often manifested among French writers. The author of a recent astronomical treatise, for example, draws a veil of deceitful words over the profound faith of Kepler, and takes evident pleasure in throwing into relief the tokens of sympathy bestowed unfortunately by the learned Laplace upon atheism.[102] Here then we have open attempts to found a prejudice against religion on the authority of science; and these attempts disturb the minds of not a few. I ask two questions on this head. Is it true, in fact, that modern naturalists are generally irreligious? Is it possible that the science of nature, rightly considered, should lead to atheism?[103]

Let us begin with the question of fact; and first of all let us settle clearly the bearing and object of this discussion. I wish to destroy a prejudice, and not to create one. I am not proposing to you to take the votes of savants, in order to know whether G.o.d exists. No. Though all the universities in Europe should unite to vote it dark at mid-day, I should not cease on that account to believe in the sun, and that, Gentlemen, in common with you all, and with the ma.s.s of my fellow-men. I have inst.i.tuted a sort of inquiry in order to ascertain whether modern naturalists have in general been led to atheistical sentiments, as some would have us believe. In appealing to the recollections of my own earlier studies and subsequent reading, I have marked the names of the men best known in the various sciences, and I have inquired what religious opinions they may have publicly manifested. I will now give you briefly the result of my labor.

I have left astronomy out of the question, considering that, notwithstanding the great notoriety of Laplace, we have in Kepler and Newton a weight of authority sufficient to counterbalance that which it is desired to connect with his name. Descending to the earth, we encounter first of all the general science of our globe, or geography.

In this order of studies a German, Ritter, enjoys an incontestable preeminence. He is called, even in France, the ”creator of scientific geography.” Scientific geography rests for support on nearly all the sciences: it proceeds from the general results of chemistry, physics, and geology. Had then the vast knowledge of Ritter turned him away from G.o.d? I had read somewhere[104] that he was one of those savants who have best realized the union of science and faith. One of my friends who was personally acquainted with him has described him to me, not only as a man who adored the Creator in the view of the creation, but as an amiable and zealous Christian, who exerted himself to communicate to others his own convictions.

From the general study of the globe, let us pa.s.s to that of the organized beings which people its surface. Does botany teach the human mind to dispense with G.o.d? Let us listen to Linnaeus. I open the _System of Nature_,[105] and on the reverse of the t.i.tle-page I read: ”O Lord, how manifold are Thy works! in wisdom hast Thou made them all: the earth is full of Thy riches.”[106] I turn over a few leaves, and I meet with a table which comprises, under the t.i.tle, _Empire of Nature_, the general cla.s.sification of beings. The commencement is as follows: ”Eternal G.o.d, all-wise and almighty! I have seen Him as it were pa.s.s before me, and I remained confounded. I have discovered some traces of His footsteps in the works of the creation; and in those works, even in the least, even in those which seem most insignificant, what might! what wisdom! what inexplicable perfection!--If thou call Him _Destiny_, thou art not mistaken, it is He upon whom all depends. If thou call Him _Nature_, thou art not mistaken, it is He from whom all takes its origin. If thou call Him _Providence_, thou speakest truly; it is by His counsel that the universe subsists.” Another great naturalist, George Cuvier, takes care to point out that ”Linnaeus used to seize with marked pleasure the numerous occasions which natural history offered him of making known the wisdom of Providence.”[107] Thus modern botany was founded in a spirit of piety. Has it, at a later period, made any discoveries calculated to efface from the life of vegetables the marks of Divine intelligence?

Allow me to introduce here a personal _souvenir_. I received lessons in my youth from an old man, who, having once been the teacher of De Candolle, remained his friend.[108] By a rather strange academical arrangement, M. Vaucher found himself set to teach us--not botany, for which he possessed both taste and genius,[109] but a science of which he knew but little, and which he liked still less. So it came to pa.s.s that a good part of the hour of lecture was often filled up with familiar conversations. These conversations took us far away from church history, which we were supposed to be learning. The misplaced botanist reverted, by a natural impulse, to his much-loved science; and I have seen him shed tears of tender emotion, in his Professor's chair, as he spoke to us of the G.o.d who made the primrose of the spring, and concealed the violet under the hedge by the wayside. Therefore is the recollection of that old man not only living in my memory, but also dear to my heart.

Still he was a savant, an enthusiastic naturalist; and, in the broad light of the nineteenth century, he felt and spoke like Linnaeus.

Let us pa.s.s to the study of animals. I had the wish, some years ago, to procure the best of modern treatises upon physiology. I was directed to the work of Professor Muller, of Berlin. This book has not lost its value,--for, this very morning, a student of our faculty of sciences came to me to borrow it, by the advice of his masters. Muller was a great physiologist, and he made an open profession of the Christian religion. Have we not the right to conclude that he believed in G.o.d? In France, I could cite more than one name in support of my thesis; I confine myself to a single fact. The attention of the scientific world has very recently been occupied with the discoveries of M. Pasteur. M.

Pasteur has ascertained that the decomposition of organized bodies, after death, is effected by the action of small animals almost imperceptible, the germs of which the larger animals carry in themselves, as living preparatives for their interment. The design of Providence reveals itself to his understanding, and he writes: ”The immediate elements of living bodies would be in a manner indestructible, if from the beings which G.o.d has created were taken away the smallest, and, in appearance, the most useless. Life would thus become impossible, because the return to the atmosphere and to the mineral kingdom of all that has ceased to live would be all at once suspended.”[110] In other words: I have studied facts. .h.i.therto incompletely observed, and my study has revealed to me a new manifestation of that Divine wisdom of which the universe bears the impression.

England possesses a naturalist of the first order, whom his fellow-countrymen take a pleasure in comparing to George Cuvier--Professor Owen. This savant lectured, a few months ago, before a numerous auditory, on the relations of religion and natural science.[111] He is fully possessed of all the information which the times afford,--is not ignorant of modern discoveries,--is, in fact, one of the princes of contemporary science. Well, Gentlemen, Mr. Owen repeats, with reference to animals, what Newton was led to say by his contemplation of the heavens, and Linnaeus by his study of the plants. He is not afraid to admire with Galen the marvellous wisdom which presided over the organization of living bodies. His discourse is ent.i.tled, _The Power of G.o.d in His Animal Creation_. The more we understand, he says, the more we admire, the more we adore. He pauses in view of the marvellous productions of nature, beside which the most delicate works of human industry appear, beneath the microscope, but coa.r.s.e, rough hewings; he compares our most highly finished machines to the living machines made by the hand of G.o.d, and infers that, not to discern intelligence in the relation of means to ends, necessarily implies in the mind a defect similar to that of eyes which are unable to distinguish colors. Mr. Owen declares that such a state of mind and feeling in a naturalist may provoke blame from some and pity from others, and remains for him, so far as he is concerned, absolutely incomprehensible.

Again, do the most learned chemists find in the study of the elements of matter a revelation of atheism? M. Liebig, I have been told, is one of the first chemists of our epoch. He believed he had discovered an application of chemistry to agriculture, the effect of which would be to furnish a remedy to the exhaustion of the soil. His discovery turned out false, and a more attentive study of his subject led him to ascertain that the object which he was pursuing was actually realized by Divine Providence in a way of which he had had no suspicion. The following is his own account of this, published in 1862: ”After having submitted all the facts to a new and very searching examination, I discovered the cause of my error. I had sinned against the wisdom of the Creator, and I had received my just punishment. I was wis.h.i.+ng to perfect His work, and, in my blindness, I thought that in the admirable chain of laws which preside over life at the surface of the earth, and maintain it ever in freshness, there was wanting a link which I, feeble and impotent worm, was to supply. Provision had been made for this beforehand, but in a way so wonderful, that the possibility of such a law had not so much as dawned upon the human understanding.”[112] Here is a confession very n.o.ble in its humility; and to this chemist, who thus renders glory to G.o.d, no one of his colleagues could say: ”If you had as much science as we, you would say no more about the wisdom of the Creator.”

Let us pa.s.s on to natural philosophers. I have taken a special interest in this part of my inquiry, because I had read in the productions of a literary man of Paris, that modern physics have placed those at fault who defend the doctrine of the living and true G.o.d. I inquired accordingly of a man, very well able to give me the information, whether there exists in Europe a natural philosopher holding a position of quite exceptional distinction. I received for reply: ”You may say boldly that, by the unanimous consent of men of science, Mr. Faraday, in regard both to the greatness and range of his discoveries, is the first natural philosopher living.” After having thus made myself sure, therefore, on this point, I took the liberty of writing to Mr. Faraday the following letter:
