What is Darwinism?

by Charles Hodge

Agassiz.

Every one knows that the illustrious Agassiz, over whose recent grave the world stands weeping, was from the beginning a pronounced and earnest opponent of Mr. Darwin's theory. He wrote as a naturalist, and therefore his objections are principally directed against the theory of evolution, which he regarded as not only destitute of any scientific basis, but as subversive of the best established facts in zoölogy. Nevertheless it is evident that his zeal was greatly intensified by his apprehension that a theory which obliterates all evidence of the being of God from the works of nature, endangered faith in that great doctrine itself. The Rev. Dr. Peabody, in the discourse delivered on the occasion of Professor Agassiz's funeral, said: "I cannot close this hasty and inadequate, yet fervent and hearty tribute, without recalling to your memory the reverent spirit in which he pursued his scientific labors. Nearly forty years ago, in his first great work on fossil fishes, in developing principles of classification, he wrote in quotations, 'An invisible thread in all ages runs through this immense diversity, exhibiting as a general result that there is a continual progress in development ending in man, the four classes of vertebrates presenting the intermediate steps, and the invertebrates the constant accessory accompaniment. Have we not here the manifestation of a mind as powerful as prolific? an act of intelligence as sublime as provident? the marks of goodness as infinite as wise? the most palpable demonstration of the existence of a personal God, author of all this; ruler of the universe, and the dispenser of all good? This at least is what I read in the works of creation.' And it was what he ever read, and with profound awe and adoration. To this exalted faith he was inflexibly loyal. The laws of nature were to him the eternal Word of God.

"His repugnance to Darwinism grew in great part from his apprehension of its atheistical tendency,—an apprehension which I confess I cannot share; for I forget not that these theories, now in the ascendent, are maintained by not a few devout Christian men, and while they appear to me unproved and incapable of demonstration, I could admit them without parting with one iota of my faith in God and Christ. Yet I cannot but sympathize most strongly with him in the spirit in which he resisted what seemed to him lese-majesty against the sovereign of the universe. Nor was his a theoretical faith. His whole life, in its broad philanthropy, in its pervading spirit of service, in its fidelity to arduous trusts and duties, and in its simplicity and truthfulness, bespoke one who was consciously fulfilling a mission from God to his fellow-men."

The words "evolution" and "Darwinism" are so often in this country, but not in Europe, used interchangeably, that it is conceivable that Dr. Peabody could retain his faith in God, and yet admit the doctrine of evolution. But it is not conceivable that any man should adopt the main element of Mr. Darwin's theory, viz., the denial of all final causes, and the assertion, that since the first creation of matter and life, God has left the universe to the control of unintelligent physical causes, so that all the phenomena of the plants and animals, all that is in man, and all that has ever happened on the earth, is due to physical force, and yet retain his faith in Christ. On that theory, there have been no supernatural revelation, no miracles; Christ is not risen, and we are yet in our sins. It is not thus that this matter is regarded abroad. The Christians of Germany say that the only alternative these theories leave us, is Heathenism or Christianity; "Heidenthum oder Christenthum, Die Frage der Zeit."

Janet.

Janet, a professor of philosophy, is the author of a book on the Materialism of Büchner.[34] The greater part of the last chapter of his work is devoted to Darwinism. He says, "Dr. Büchner invoked (Darwin's book) as a striking confirmation of his doctrine." (p. 154) What Büchner's doctrine is has been shown on a previous page. The points of coincidence between Darwin's system and his are, that both regard mind as a mere function of living matter; and both refer all the organs and organisms of living things to the unconscious, unintelligent operation of physical causes. Büchner's way of accounting for complicated organs was, "that the energy of the elements and forces of matter, which in their fated and accidental occurrence must have produced innumerable forms, which must needs limit each other mutually, and correspond, apparently, the one with the other, as if they were made for that purpose. Out of all those forms, they only have survived which were adapted, in some manner, to the conditions of the medium in which they were placed." (p. 30) This is very clumsy. No wonder Büchner preferred Darwin's method. The two systems are, indeed, exactly the same, but Mr. Darwin has a much more winning way of presenting it.

Professor Janet does not seem to have much objection to the doctrine of evolution in itself; it is the denial of teleology that he regards as the fatal element of Mr. Darwin's theory. "According to us," he says, "the true stumbling-block of Mr. Darwin's theory, the perilous and slippery point, is the passage from artificial to natural selection; it is when he wants to establish that a blind and designless nature has been able to obtain, by the occurrence of circumstances, the same results which man obtains by thoughtful and well calculated industry." (p. 174)

Towards the end of his volume he says: "We shall conclude by a general observation. Notwithstanding the numerous objections we have raised against Mr. Darwin's theory, we do not declare ourselves hostile to a system of which zoölogists are the only competent judges. We are neither for nor against the transmutation of species, neither for nor against the principle of natural selection. The only positive conclusion of our debate is this: no principle hitherto known, neither the action of media, nor habit, nor natural selection, can account for organic adaptations without the intervention of the principle of finality. Natural selection, unguided, submitted to the laws of a pure mechanism, and exclusively determined by accidents, seems to me, under another name, the chance proclaimed by Epicurus, equally barren, equally incomprehensible; on the other hand, natural selection guided beforehand by a provident will, directed towards a precise end by intentional laws, might be the means which nature has selected to pass from one stage of being to another, from one form to another, to bring to perfection life throughout the universe, and to rise by a continuous process from the monad to man. Now, I ask Mr. Darwin himself, what interest has he in maintaining that natural selection is not guided—not directed? What interest has he in substituting accidental causes for every final cause? I cannot see. Let him admit that in natural, as well as in artificial selection, there may be a choice and direction; his principle immediately becomes much more fruitful than it was before. His hypothesis, then, whilst having the advantage of exempting science from the necessity of introducing the personal and miraculous intervention of God in the creation of each species, yet would be free from the banishing out of the universe an all-provident thought, and of submitting everything to blind and brute chance." (pp. 198, 199) Professor Janet asks far too much of Mr. Darwin. To ask him to give up his denial of final causes is like asking the Romanists to give up the Pope. That principle is the life and soul of his system.
