POLITICS, diplomacy, law, art, and history had opened no outlet for future energy or effort, but a man must do something, even in Portland Place, when winter is dark and winter evenings are exceedingly long. At that moment Darwin was convulsing society. The geological champion of Darwin was Sir Charles Lyell, and the Lyells were intimate at the Legation. Sir Charles constantly said of Darwin, what Palgrave said of Tennyson, that the first time he came to town, Adams should be asked to meet him, but neither of them ever came to town, or ever cared to meet a young American, and one could not go to them because they were known to dislike intrusion. The only Americans who were not allowed to intrude were the half-dozen in the Legation. Adams was content to read Darwin, especially his "Origin of Species" and his "Voyage of the Beagle." He was a Darwinist before the letter; a predestined follower of the tide; but he was hardly trained to follow Darwin's evidences. Fragmentary the British mind might be, but in those days it was doing a great deal of work in a very un-English way, building up so many and such vast theories on such narrow foundations as to shock the conservative, and delight the frivolous. The atomic theory; the correlation and conservation of energy; the mechanical theory of the universe; the kinetic theory of gases, and Darwin's Law of Natural Selection, were examples of what a young man had to take on trust. Neither he nor any one else knew enough to verify them; in his ignorance of mathematics, he was particularly helpless; but this never stood in his way. The ideas were new and seemed to lead somewhere — to some great generalization which would finish one's clamor to be educated. That a beginner should understand them all, or believe them all, no one could expect, still less exact. Henry Adams was Darwinist because it was easier than not, for his ignorance exceeded belief, and one must know something in order to contradict even such triflers as Tyndall and Huxley.
By rights, he should have been also a Marxist but some narrow trait of the New England nature seemed to blight socialism, and he tried in vain to make himself a convert. He did the next best thing; he became a Comteist, within the limits of evolution. He was ready to become anything but quiet. As though the world had not been enough upset in his time, he was eager to see it upset more. He had his wish, but he lost his hold on the results by trying to understand them.
He never tried to understand Darwin; but he still fancied he might get the best part of Darwinism from the easier study of geology; a science which suited idle minds as well as though it were history. Every curate in England dabbled in geology and hunted for vestiges of Creation. Darwin hunted only for vestiges of Natural Selection, and Adams followed him, although he cared nothing about Selection, unless perhaps for the indirect amusement of upsetting curates. He felt, like nine men in ten, an instinctive belief in Evolution, but he felt no more concern in Natural than in unnatural Selection, though he seized with greediness the new volume on the "Antiquity of Man" which Sir Charles Lyell published in 1863 in order to support Darwin by wrecking the Garden of Eden. Sir Charles next brought out, in 1866, a new edition of his "Principles," then the highest text-book of geology; but here the Darwinian doctrine grew in stature. Natural Selection led back to Natural Evolution, and at last to Natural Uniformity. This was a vast stride. Unbroken Evolution under uniform conditions pleased every one — except curates and bishops; it was the very best substitute for religion; a safe, conservative practical, thoroughly Common-Law deity. Such a working system for the universe suited a young man who had just helped to waste five or ten thousand million dollars and a million lives, more or less, to enforce unity and uniformity on people who objected to it; the idea was only too seductive in its perfection; it had the charm of art. Unity and Uniformity were the whole motive of philosophy, and if Darwin, like a true Englishman, preferred to back into it — to reach God a posteriori — rather than start from it, like Spinoza, the difference of method taught only the moral that the best way of reaching unity was to unite. Any road was good that arrived. Life depended on it. One had been, from the first, dragged hither and thither like a French poodle on a string, following always the strongest pull, between one form of unity or centralization and another. The proof that one had acted wisely because of obeying the primordial habit of nature flattered one's self-esteem. Steady, uniform, unbroken evolution from lower to higher seemed easy. So, one day when Sir Charles came to the Legation to inquire about getting his "Principles" properly noticed in America, young Adams found nothing simpler than to suggest that he could do it himself if Sir Charles would tell him what to say. Youth risks such encounters with the universe before one succumbs to it, yet even he was surprised at Sir Charles's ready assent, and still more so at finding himself, after half an hour's conversation, sitting down to clear the minds of American geologists about the principles of their profession. This was getting on fast; Arthur Pendennis had never gone so far.
The geologists were a hardy class, not likely to be much hurt by Adams's learning, nor did he throw away much concern on their account. He undertook the task chiefly to educate, not them, but himself, and if Sir Isaac Newton had, like Sir Charles Lyell, asked him to explain for Americans his last edition of the "Principia," Adams would have jumped at the chance. Unfortunately the mere reading such works for amusement is quite a different matter from studying them for criticism. Ignorance must always begin at the beginning. Adams must inevitably have begun by asking Sir Isaac for an intelligible reason why the apple fell to the ground. He did not know enough to be satisfied with the fact. The Law of Gravitation was so-and-so, but what was Gravitation? and he would have been thrown quite off his base if Sir Isaac had answered that he did not know.
At the very outset Adams struck on Sir Charles's Glacial Theory or theories. He was ignorant enough to think that the glacial epoch looked like a chasm between him and a uniformitarian world. If the glacial period were uniformity, what was catastrophe? To him the two or three labored guesses that Sir Charles suggested or borrowed to explain glaciation were proof of nothing, and were quite unsolid as support for so immense a superstructure as geological uniformity. If one were at liberty to be as lax in science as in theology, and to assume unity from the start, one might better say so, as the Church did, and not invite attack by appearing weak in evidence. Naturally a young man, altogether ignorant, could not say this to Sir Charles Lyell or Sir Isaac Newton; but he was forced to state Sir Charles's views, which he thought weak as hypotheses and worthless as proofs. Sir Charles himself seemed shy of them. Adams hinted his heresies in vain. At last he resorted to what he thought the bold experiment of inserting a sentence in the text, intended to provoke correction. "The introduction [by Louis Agassiz] of this new geological agent seemed at first sight inconsistent with Sir Charles's argument, obliging him to allow that causes had in fact existed on the earth capable of producing more violent geological changes than would be possible in our own day." The hint produced no effect. Sir Charles said not a word; he let the paragraph stand; and Adams never knew whether the great Uniformitarian was strict or lax in his uniformitarian creed; but he doubted.
Objections fatal to one mind are futile to another, and as far as concerned the article, the matter ended there, although the glacial epoch remained a misty region in the young man's Darwinism. Had it been the only one, he would not have fretted about it; but uniformity often worked queerly and sometimes did not work as Natural Selection at all. Finding himself at a loss for some single figure to illustrate the Law of Natural Selection, Adams asked Sir Charles for the simplest case of uniformity on record. Much to his surprise Sir Charles told him that certain forms, like Terebratula, appeared to be identical from the beginning to the end of geological time. Since this was altogether too much uniformity and much too little selection, Adams gave up the attempt to begin at the beginning, and tried starting at the end — himself. Taking for granted that the vertebrates would serve his purpose, he asked Sir Charles to introduce him to the first vertebrate. Infinitely to his bewilderment, Sir Charles informed him that the first vertebrate was a very respectable fish, among the earliest of all fossils, which had lived, and whose bones were still reposing, under Adams's own favorite Abbey on Wenlock Edge.
By this time, in 1867 Adams had learned to know Shropshire familiarly, and it was the part of his diplomatic education which he loved best. Like Catherine Olney in "Northanger Abbey," he yearned for nothing so keenly as to feel at home in a thirteenth-century Abbey, unless it were to haunt a fifteenth-century Prior's House, and both these joys were his at Wenlock. With companions or without, he never tired of it. Whether he rode about the Wrekin, or visited all the historical haunts from Ludlow Castle and Stokesay to Boscobel and Uriconium; or followed the Roman road or scratched in the Abbey ruins, all was amusing and carried a flavor of its own like that of the Roman Campagna; but perhaps he liked best to ramble over the Edge on a summer afternoon and look across the Marches to the mountains of Wales. The peculiar flavor of the scenery has something to do with absence of evolution; it was better marked in Egypt: it was felt wherever time-sequences became interchangeable. One's instinct abhors time. As one lay on the slope of the Edge, looking sleepily through the summer haze towards Shrewsbury or Cader Idris or Caer Caradoc or Uriconium, nothing suggested sequence. The Roman road was twin to the railroad; Uriconium was well worth Shrewsbury; Wenlock and Buildwas were far superior to Bridgnorth. The shepherds of Caractacus or Offa, or the monks of Buildwas, had they approached where he lay in the grass, would have taken him only for another and tamer variety of Welsh thief. They would have seen little to surprise them in the modern landscape unless it were the steam of a distant railway. One might mix up the terms of time as one liked, or stuff the present anywhere into the past, measuring time by Falstaff's Shrewsbury clock, without violent sense of wrong, as one could do it on the Pacific Ocean; but the triumph of all was to look south along the Edge to the abode of one's earliest ancestor and nearest relative, the ganoid fish, whose name, according to Professor Huxley, was Pteraspis, a cousin of the sturgeon, and whose kingdom, according to Sir Roderick Murchison, was called Siluria. Life began and ended there. Behind that horizon lay only the Cambrian, without vertebrates or any other organism except a few shell-fish. On the further verge of the Cambrian rose the crystalline rocks from which every trace of organic existence had been erased.
