So the cause of the glacial epoch remained at the mercy of Lyell and Croll, although Geikie had split up the period into half-a-dozen intermittent chills in recent geology and in the northern hemisphere alone, while no geologist had ventured to assert that the glaciation of the southern hemisphere could possibly be referred to a horizon more remote. Continents still rose wildly and wildly sank, though Professor Suess of Vienna had written an epoch-****** work, showing that continents were anchored like crystals, and only oceans rose and sank. Lyell's genial uniformity seemed genial still, for nothing had taken its place, though, in the interval, granite had grown young, nothing had been explained, and a bewildering system of huge overthrusts had upset geological mechanics. The textbooks refused even to discuss theories, frankly throwing up their hands and avowing that progress depended on studying each rock as a law to itself.
Adams had no more to do with the correctness of the science than the gar-pike or the Port Jackson shark, for its correctness in no way concerned him, and only impertinence could lead him to dispute or discuss the principles of any science; but the history of the mind concerned the historian alone, and the historian had no vital concern in anything else, for he found no change to record in the body. In thought the Schools, like the Church, raised ignorance to a faith and degraded dogma to heresy. Evolution survived like the trilobites without evolving, and yet the evolutionists held the whole field, and had even plucked up courage to rebel against the Cossack ukase of Lord Kelvin forbidding them to ask more than twenty million years for their experiments. No doubt the geologists had always submitted sadly to this last and utmost violence inflicted on them by the Pontiff of Physical Religion in the effort to force unification of the universe; they had protested with mild conviction that they could not state the geological record in terms of time; they had murmured Ignoramus under their breath; but they had never dared to assert the Ignorabimus that lay on the tips of their tongues.
Yet the admission seemed close at hand. Evolution was becoming change of form broken by freaks of force, and warped at times by attractions affecting intelligence, twisted and tortured at other times by sheer violence, cosmic, chemical, solar, supersensual, electrolytic -- who knew what? -- defying science, if not denying known law; and the wisest of men could but imitate the Church, and invoke a "larger synthesis" to unify the anarchy again.
Historians have got into far too much trouble by following schools of theology in their efforts to enlarge their synthesis, that they should willingly repeat the process in science. For human purposes a point must always be soon reached where larger synthesis is suicide.
Politics and geology pointed alike to the larger synthesis of rapidly increasing complexity; but still an elderly man knew that the change might be only in himself. The admission cost nothing. Any student, of any age, thinking only of a thought and not of his thought, should delight in turning about and trying the opposite motion, as he delights in the spring which brings even to a tired and irritated statesman the larger synthesis of peach-blooms, cherry-blossoms, and dogwood, to prove the folly of fret.
Every schoolboy knows that this sum of all knowledge never saved him from whipping; mere years help nothing; King and Hay and Adams could neither of them escape floundering through the corridors of chaos that opened as they passed to the end; but they could at least float with the stream if they only knew which way the current ran. Adams would have liked to begin afresh with the Limulus and Lepidosteus in the waters of Braintree, side by side with Adamses and Quincys and Harvard College, all unchanged and unchangeable since archaic time; but what purpose would it serve? A seeker of truth -- or illusion -- would be none the less restless, though a shark!
