More than a generation has passed since then. Twenty-five years afterward I went back to the scene of the meeting. Except myself, the whole company are dead, and the very scene of our acting and thinking has disappeared down to its geological basis, pillaged, burnt, and become a horror to see; but, among the memories which are the only realities left to it, this image of Emerson claiming kinship with the forest stands out alone, and I feel as if I had stood for a moment on a mount of transfiguration, and seen, as if in a vision, the typical American, the noblest in the idealization of the American, of all the race. Lowell was of a more cosmopolitan type, of a wider range of sympathies and affections, accepted and bestowed, and to me a friend, loved as Jonathan loved David; but, as a unique, idealized individuality, Emerson looms up in that Arcadian dream more and more the dominant personality. It is as character, and not as accomplishment or education, that he holds his own in all comparisons with his contemporaries, the fine, crystallized mind, the keen, clear-faceted thinker and seer. I loved more Agassiz and Lowell, but we shall have many a Lowell and Agassiz before we see Emerson's like again. Attainments will be greater, and discovery and accomplishments will surpass themselves as we go on, but to be, as Emerson was, is absolute and complete existence.

Agassiz was, of all our company, the acknowledged master; loved by all, even to the unlettered woodsmen, who ran to meet his service as to no other of the company; by all the members of it reverenced as not even Emerson was; the largest in personality and in universality of knowledge of all the men I have ever known. No one who did not know him personally can conceive the hold he had on everybody who came into relations with him. His vast command of scientific facts, and his ready command of them for all educational purposes, his enthusiasm for science and the diffusion of it, even his fascinating way of imparting it to others, had even less to do with his popularity than the magnetism of his presence and the sympathetic faculty which enabled him to find at once the plane on which he should meet whomever he had to deal with. Of his scientific position I cannot speak, though I can see that his was the most powerful of the scientific influences of that epoch in America. When we were traveling it was always in my boat, and we moved as his investigations prompted, wherever there seemed to be a promise of some addition to his collections. We dredged and netted water and air wherever we went, and of course there arose a certain kind of intimacy, which was partly that of a camaraderie in which we were approximately equals, that of the backwoods life in which I was, if a comparison were to be made, the superior, and partly that of teacher and pupil; for, with trifling attainments, I had the passion of scientific acquisition, and all that Agassiz needed to open the store of his knowledge was the willingness of another to learn.

The odium scientificum, which I notice is no less bitter than the variety theologicum, has, in these years, poured on Agassiz the floods of its opprobrium, and even the little dogs of physical science bark at his name; but his greater contemporaries knew and esteemed him better. The revival of the evolutionary hypothesis by Darwin, and the controversies growing out of it, then filled the air, and Agassiz paid the penalty of his eminence and constancy to the system in which he had been grounded by his master, Cuvier. He was attacked and insulted by men who had never made an observation, and, what was more curious, as a panderer to the theological prejudices of the past. But in my mind was still the memory of a former outcry and theological persecution of him, because he had himself laid down what might be considered the forerunner of the doctrine of evolution,—the declaration that the human race could not have been the offspring of one Adam, but must have had a multiple beginning. The result of this was to bring on his head the execrations of the theological world in a storm which no one who had witnessed it was likely to forget or take for other than what it was, the proof of his absolute scientific honesty,—a proof needed by no one who knew him personally, but which, in view of the later animosity shown him, requires reaffirmation.

As I was much with him at this time, and perhaps, out of his family, the one to whom he talked with the greatest freedom and fullness on the subject, owing to my own intense interest in it, it cannot be amiss that I state his exact position as far as he let me see it. It must be remembered that the doctrine of evolution, as he knew it, and in the only form in which it was then stated, was simply and purely that of development by natural selection acting on chance variation, and differing mainly by this from the doctrine of Lamarck, which had long been rejected by the scientific world at large. We have seen since then that this primitive doctrine has been largely supplemented by other theories, and that it no longer stands before the scientific world in the bare simplicity of Darwin's original statement, though even he, at a later date, claimed natural selection not as the only but as the most influential agency of variation of species in creation; repudiating, however, a plan in the universe, and not demanding the influence of the conscious mind on creation. Agassiz's primary objection to the doctrine was that it left the creator out of creation, for it distinctly repudiated the element of design in it; and, though he did not recognize the Creator of Genesis, he could not dispense with the supreme mind.

Myself a convert to the doctrine of evolution, in as absolute a form as it is held even by the materialists, though differently, I am persuaded that if Agassiz had lived long enough to see the latest development of it he would have accepted it, as did Professor Owen, who was, like Agassiz, and possibly even more literally, a believer in the designer of the universe. The fundamental ground for Agassiz's rejection of it is stated by himself in one of the lectures delivered at Cambridge, as follows: "I believe that all these correspondences between the different aspects of animal life are the manifestations of mind acting consciously with intention towards one object from beginning to end. This view is in accordance with the working of our minds; it is an instinctive recognition of a mental power with which our own is akin, manifesting itself in nature. For this reason, more than any other, perhaps, do I hold that this world of ours was not the result of the action of unconscious organic forces, but the work of an intelligent, conscious power." Whatever might have been the process by which the orderly creation was produced (into which he did not inquire), it was the result of a definite plan and the work of design. The immutability of species, as he defined species, was the logical consequence of this theory, and that, it seems to me, is the substantial difference between him and Darwin.

But Agassiz was no sectarian, and held no other creed than a belief in the Creator. In the fibre of the man was the consciousness of the immanent deity, rooted, perhaps, in that influence of his early theological environage from which no man can ever escape, though he may rebel against it; and the almost universal deduction by the scientific world from Darwin's theory then was that there could be no divine design in creation. It was this negation of the direction of the great artist in the process of creation against which Agassiz rebelled; and although, at a later phase of the conflict, Darwin himself protested against the implication sometimes drawn from his theory, there can be no question that at that moment the general evolutionary opinion was that the hypothesis of a divine authorship of creation was superfluous. Agassiz maintained the presence of "Conscious Mind in Creation;" Darwin did not deny it explicitly, nor did he admit it.

As a matter of observation, no case of a development of one species from another has ever been noted, and the evidence for it is precisely analogous to that adduced by Agassiz, "that it is in accordance with the working of our minds," still further illuminated by the side-lights which science has thrown on it since Agassiz died. The ultimate decision in the individual mind will be according to the bias for or against the "conscious mind" or automatic creation; and it must not be forgotten that one of the most powerful arguments for a large evolution was the discovery by Agassiz that the embryo of the highest organizations passes through an evolution similar to that of the animal creation. Professor Martins—a leading French scientist and an evolutionist—says of Agassiz: "Another of these precursors of modern science is Louis Agassiz. The oldest fossil forms have a simpler organization than the later ones, and represent some stage of the embryonic development of the latter. This truth, established by Agassiz, has, more than any other, enlightened the history of creation, and prepared for the generalization by which the whole may be comprehended. The oldest fishes known are all more or less related to the sharks and skates; their teeth and scales only, with small portions of the skeleton, have been preserved. Their form, widely different from that of the living species, recalls that of the embryo of our living fishes. This is a truth which Louis Agassiz was the first to proclaim to the scientific world."[1]

[Footnote 1: De l'Origine du Monde organique.]

But, beyond this question as to the evidence of mutability of species which Agassiz did not find, he took the position "that the hypothesis of the method of creation by evolution exceeded physical science and became theology, which belonged to the province of theology, into which he had no intention of venturing." That was his statement to me during the interval between the two attacks of brain trouble from the latter of which he died. Science, to his understanding, was observation and classification, arrangement, and it had no function in investigating the causes or modus operandi through which things became what they were.

Amongst the evolutionists whom I have known there have been several who did not accept without modification the theory of natural selection, and supplemented it by design, amongst whom I may mention the great American botanist, Asa Gray,—one of the most distinguished of Darwinians,—who accepted the method of evolution as the modus operandi of the Supreme Intelligence. Professor Jeffries Wyman, the associate of Agassiz in the University, who was one of the doctors of our Adirondack company, accepted in a qualified manner the theory of evolution, but his premature and lamented death set the seal to his conclusions before they were complete, though I have always had the impression that his position was similar to that of Gray. To my question one day as to his conclusions, he replied, with a caution characteristic of the man and very unlike the resolute attitude of Agassiz before the question which the Sphinx proposes still, "An evolution of some sort there certainly was," but nothing more would he say. The loss to American science in his death can never be estimated, for his mind was of that subtle and inductive nature which is needed for such a study, fine to poetic delicacy, penetrating with all the acumen of a true scientific imagination, but modest to excess, and personally so attached to Agassiz that he would with reluctance give expression to a difference from him, though that he did differ was no occasion for abatement of their mutual regard. Wyman's was the poetry of scientific research, Agassiz's its prose, and they offered a remarkable example of mental antithesis, from which, had Wyman lived, much might have been expected through their association in study. Wyman had all the delicacy of a fine feminine organization, wedded unfortunately to a fragile constitution, but the friendship he held for the robust and dominating character of the great Switzer was to the utmost reciprocated.
