The interdependence of nations, indeed, is much overestimated by sentimentalists, chiefly of the economic faculty. They permit the gyrations of foreign exchange to alarm them. But what is it to a man in Kansas, or Uruguay, or Saskatchewan, expressed in hard figures, that a million Poles have been slaughtered, or that the Turks have again ravaged Armenia, or that the British and Dutch are at odds over human liberty and the oil-wells of Mesopotamia, or that Belgrade has fallen, or that the French refuse to go back to work but propose to live hereafter by highway robbery? It is, at most, a matter of ten per cent. This is all he feels, and this is all he cares. If he shows any excitement or even any interest it is because some drive manager has played upon his credulities, as Dr. Wells seeks to play upon the credulities of all of us. For one, I refuse to be alarmed. If Paris were burned tomorrow, I’d scarcely know it on my estates in Maryland, feeding upon my razor-back hams, listening to Caruso’s ghost, and reading the state papers of Thomas Jefferson. Even if I tired of that idyllic life and went abroad, I’d admire the ruins quite as much as I have ever admired the Trocadero or the Eiffel tower. Both, perhaps, would escape the fire--and no doubt the incendiaries would make off with the best things in the Luxembourg and the Louvre. Nor am I greatly alarmed by the current doctrine that the late war stamped out the best strains of all the contesting nations, and that they are rapidly sinking to the level of their lower classes. This alarm is raised in an inflammatory book called “Is America Safe for Democracy?” by one William McDougall, a Scotchman imported to civilize the sophomores at Harvard. The McDougall also raises and parades another hobgoblin, once a favorite of the immortal zany, Major-General Roosevelt. That is the bugaboo of race suicide, especially among the upper classes. The wops in the ditch and the Slovaks in the mining towns, it appears, breed up to the limit of human endurance, but bank presidents seldom have more than four or five legitimate children, and the great majority of poets, metaphysicians, Oxford dons, lady Ph.D.s, assyriologists and moving-picture actors are childless, and perhaps even sterile. At the present rate of reproduction, says Prof. McDougall, 1000 Harvard graduates of today will have but 50 descendants 200 years hence, whereas 1000 Rumanians will have 100,000.
