He felt almost aggrieved to find Walcott so vigorously acting the part of Comus as to have flung the ganoid all the way off to Colorado and far back into the Lower Trenton limestone, making the Pteraspis as modern as a Mississippi gar-pike by spawning an ancestry for him, indefinitely more remote, in the dawn of known organic life. A few thousand feet, more or less, of limestone were the liveliest amusement to the ganoid, but they buried the uniformitarian alive, under the weight of his own uniformity.
Not for all the ganoid fish that ever swam, would a discreet historian dare to hazard even in secret an opinion about the value of Natural Selection by Minute Changes under Uniform Conditions, for he could know no more about it than most of his neighbors who knew nothing; but natural selection that did not select -- evolution finished before it began -- minute changes that refused to change anything during the whole geological record - survival of the highest order in a fauna which had no origin -- uniformity under conditions which had disturbed everything else in creation -- to an honest-meaning though ignorant student who needed to prove Natural Selection and not assume it, such sequence brought no peace. He wished to be shown that changes in form caused evolution in force; that chemical or mechanical energy had by natural selection and minute changes, under uniform conditions, converted itself into thought. The ganoid fish seemed to prove -- to him -- that it had selected neither new form nor new force, but that the curates were right in thinking that force could be increased in volume or raised in intensity only by help of outside force. To him, the ganoid was a huge perplexity, none the less because neither he nor the ganoid troubled Darwinians, but the more because it helped to reveal that Darwinism seemed to survive only in England. In vain he asked what sort of evolution had taken its place. Almost any doctrine seemed orthodox. Even sudden conversions due to mere vital force acting on its own lines quite beyond mechanical explanation, had cropped up again. A little more, and he would be driven back on the old independence of species.
What the ontologist thought about it was his own affair, like the theologist's views on theology, for complexity was nothing to them; but to the historian who sought only the direction of thought and had begun as the confident child of Darwin and Lyell in 1867, the matter of direction seemed vital.
Then he had entered gaily the door of the glacial epoch, and had surveyed a universe of unities and uniformities. In 1900 he entered a far vaster universe, where all the old roads ran about in every direction, overrunning, dividing, subdividing, stopping abruptly, vanishing slowly, with side-paths that led nowhere, and sequences that could not be proved. The active geologists had mostly become specialists dealing with complexities far too technical for an amateur, but the old formulas still seemed to serve for beginners, as they had served when new.
