A law of acceleration, definite and constant as any law of mechanics, cannot be supposed to relax its energy to suit the convenience of man. No one is likely to suggest a theory that man's convenience had been consulted by Nature at any time, or that Nature has consulted the convenience of any of her creations, except perhaps the Terebratula. In every age man has bitterly and justly complained that Nature hurried and hustled him, for inertia almost invariably has ended in tragedy. Resistance is its law, and resistance to superior mass is futile and fatal.
Fifty years ago, science took for granted that the rate of acceleration could not last. The world forgets quickly, but even today the habit remains of founding statistics on the faith that consumption will continue nearly stationary. Two generations, with John Stuart Mill, talked of this stationary period, which was to follow the explosion of new power. All the men who were elderly in the forties died in this faith, and other men grew old nursing the same conviction, and happy in it; while science, for fifty years, permitted, or encouraged, society to think that force would prove to be limited in supply. This mental inertia of science lasted through the eighties before showing signs of breaking up; and nothing short of radium fairly wakened men to the fact, long since evident, that force was inexhaustible. Even then the scientific authorities vehemently resisted.
Nothing so revolutionary had happened since the year 300. Thought had more than once been upset, but never caught and whirled about in the vortex of infinite forces. Power leaped from every atom, and enough of it to supply the stellar universe showed itself running to waste at every pore of matter. Man could no longer hold it off. Forces grasped his wrists and flung him about as though he had hold of a live wire or a runaway automobile; which was very nearly the exact truth for the purposes of an elderly and timid single gentleman in Paris, who never drove down the Champs Elysees without expecting an accident, and commonly witnessing one; or found himself in the neighborhood of an official without calculating the chances of a bomb. So long as the rates of progress held good, these bombs would double in force and number every ten years.
Impossibilities no longer stood in the way. One's life had fattened on impossibilities. Before the boy was six years old, he had seen four impossibilities made actual — the ocean-steamer, the railway, the electric telegraph, and the Daguerreotype; nor could he ever learn which of the four had most hurried others to come. He had seen the coal-output of the United States grow from nothing to three hundred million tons or more. What was far more serious, he had seen the number of minds, engaged in pursuing force — the truest measure of its attraction — increase from a few scores or hundreds, in 1838, to many thousands in 1905, trained to sharpness never before reached, and armed with instruments amounting to new senses of indefinite power and accuracy, while they chased force into hiding-places where Nature herself had never known it to be, making analyses that contradicted being, and syntheses that endangered the elements. No one could say that the social mind now failed to respond to new force, even when the new force annoyed it horribly. Every day Nature violently revolted, causing so-called accidents with enormous destruction of property and life, while plainly laughing at man, who helplessly groaned and shrieked and shuddered, but never for a single instant could stop. The railways alone approached the carnage of war; automobiles and fire-arms ravaged society, until an earthquake became almost a nervous relaxation. An immense volume of force had detached itself from the unknown universe of energy, while still vaster reservoirs, supposed to be infinite, steadily revealed themselves, attracting mankind with more compulsive course than all the Pontic Seas or Gods or Gold that ever existed, and feeling still less of retiring ebb.
In 1850, science would have smiled at such a romance as this, but, in 1900, as far as history could learn, few men of science thought it a laughing matter. If a perplexed but laborious follower could venture to guess their drift, it seemed in their minds a toss-up between anarchy and order. Unless they should be more honest with themselves in the future than ever they were in the past, they would be more astonished than their followers when they reached the end. If Karl Pearson's notions of the universe were sound, men like Galileo, Descartes, Leibnitz, and Newton should have stopped the progress of science before 1700, supposing them to have been honest in the religious convictions they expressed. In 1900 they were plainly forced back; on faith in a unity unproved and an order they had themselves disproved. They had reduced their universe to a series of relations to themselves. They had reduced themselves to motion in a universe of motions, with an acceleration, in their own case of vertiginous violence. With the correctness of their science, history had no right to meddle, since their science now lay in a plane where scarcely one or two hundred minds in the world could follow its mathematical processes; but bombs educate vigorously, and even wireless telegraphy or airships might require the reconstruction of society. If any analogy whatever existed between the human mind, on one side, and the laws of motion, on the other, the mind had already entered a field of attraction so violent that it must immediately pass beyond, into new equilibrium, like the Comet of Newton, to suffer dissipation altogether, like meteoroids in the earth's atmosphere. If it behaved like an explosive, it must rapidly recover equilibrium; if it behaved like a vegetable, it must reach its limits of growth; and even if it acted like the earlier creations of energy — the saurians and sharks — it must have nearly reached the limits of its expansion. If science were to go on doubling or quadrupling its complexities every ten years, even mathematics would soon succumb. An average mind had succumbed already in 1850; it could no longer understand the problem in 1900.
Fortunately, a student of history had no responsibility for the problem; he took it as science gave it, and waited only to be taught. With science or with society, he had no quarrel and claimed no share of authority. He had never been able to acquire knowledge, still less to impart it; and if he had, at times, felt serious differences with the American of the nineteenth century, he felt none with the American of the twentieth. For this new creation, born since 1900, a historian asked no longer to be teacher or even friend; he asked only to be a pupil, and promised to be docile, for once, even though trodden under foot; for he could see that the new American — the child of incalculable coal-power, chemical power, electric power, and radiating energy, as well as of new forces yet undetermined — must be a sort of God compared with any former creation of nature. At the rate of progress since 1800, every American who lived into the year 2000 would know how to control unlimited power. He would think in complexities unimaginable to an earlier mind. He would deal with problems altogether beyond the range of earlier society. To him the nineteenth century would stand on the same plane with the fourth — equally childlike — and he would only wonder how both of them, knowing so little, and so weak in force, should have done so much. Perhaps even he might go back, in 1964, to sit with Gibbon on the steps of Ara Coeli.
Meanwhile he was getting education. With that, a teacher who had failed to educate even the generation of 1870, dared not interfere. The new forces would educate. History saw few lessons in the past that would be useful in the future; but one, at least, it did see. The attempt of the American of 1800 to educate the American of 1900 had not often been surpassed for folly; and since 1800 the forces and their complications had increased a thousand times or more. The attempt of the American of 1900 to educate the American of 2000, must be even blinder than that of the Congressman of 1800, except so far as he had learned his ignorance. During a million or two of years, every generation in turn had toiled with endless agony to attain and apply power, all the while betraying the deepest alarm and horror at the power they created. The teacher of 1900, if foolhardy, might stimulate; if foolish, might resist; if intelligent, might balance, as wise and foolish have often tried to do from the beginning; but the forces would continue to educate, and the mind would continue to react. All the teacher could hope was to teach it reaction.
Even there his difficulty was extreme. The most elementary books of science betrayed the inadequacy of old implements of thought. Chapter after chapter closed with phrases such as one never met in older literature: "The cause of this phenomenon is not understood"; "science no longer ventures to explain causes"; "the first step towards a causal explanation still remains to be taken"; "opinions are very much divided"; "in spite of the contradictions involved"; "science gets on only by adopting different theories, sometimes contradictory." Evidently the new American would need to think in contradictions, and instead of Kant's famous four antinomies, the new universe would know no law that could not be proved by its anti-law.
To educate — one's self to begin with — had been the effort of one's life for sixty years; and the difficulties of education had gone on doubling with the coal-output, until the prospect of waiting another ten years, in order to face a seventh doubling of complexities, allured one's imagination but slightly. The law of acceleration was definite, and did not require ten years more study except to show whether it held good. No scheme could be suggested to the new American, and no fault needed to be found, or complaint made; but the next great influx of new forces seemed near at hand, and its style of education promised to be violently coercive. The movement from unity into multiplicity, between 1200 and 1900, was unbroken in sequence, and rapid in acceleration. Prolonged one generation longer, it would require a new social mind. As though thought were common salt in indefinite solution it must enter a new phase subject to new laws. Thus far, since five or ten thousand years, the mind had successfully reacted, and nothing yet proved that it would fail to react — but it would need to jump.
