Thus the game seemed lost, in spite of the Kaiser's brilliant stroke, and the movement of Russia eastward must drag Germany after it by its mere mass. To the humble student, the loss of Hay's game affected only Hay; for himself, the game,—not the stakes,—was the chief interest; and though want of habit made him object to read his newspapers blackened,—since he liked to blacken them himself,—he was in any case condemmed to pass but a short space of time either in Siberia or in Paris, and could balance his endless columns of calculation equally in either place. The figures, not the facts, concerned his chart, and he mused deeply over his next equation. The Atlantic would have to deal with a vast continental mass of inert motion, like a glacier, which moved, and consciously moved, by mechanical gravitation alone. Russia saw herself so, and so must an American see her; he had no more to do than measure, if he could, the mass. Was volume or intensity the stronger? What and where was the vis nova that could hold its own before this prodigious ice-cap of vis inertiæ? What was movement of inertia, and what its laws?
Naturally a student knew nothing about mechanical laws, but he took for granted that he could learn, and went to his books to ask. He found that the force of inertia had troubled wiser men than he. The dictionary said that inertia was a property of matter, by which matter tends, when at rest, to remain so, and, when in motion, to move on in a straight line. Finding that his mind refused to imagine itself at rest or in a straight line, he was forced, as usual, to let it imagine something else; and since the question concerned the mind, and not matter, he decided from personal experience that his mind was never at rest, but moved,—when normal,—about something it called a motive, and never moved without motives to move it. So long as these motives were habitual, and their attraction regular, the consequent result might, for convenience, be called movement of inertia, to distinguish it from movement caused by newer or higher attraction; but the greater the bulk to move, the greater must be the force to accelerate or deflect it.
This seemed simple as running water; but simplicity is the most deceitful mistress that ever betrayed man. For years the student and the professor had gone on complaining that minds were unequally inert. The inequalities amounted to contrasts. One class of minds responded
