I am only a philosopher, and there is only one thing that a philosopher can be relied on to do. You know that the function of statistics has been ingeniously described as being the refutation of other statistics. Well, a philosopher can always contradict other philosophers. In ancient times philosophers defined man as the rational animal; and philosophers since then have always found much more to say about the rational than about the animal part of the definition. But looked at candidly, reason bears about the same proportion to the rest of human nature that we in this hall bear to the rest of America, Europe, Asia, Africa, and Polynesia. Reason is one of the very feeblest of Nature's forces, if you take it at any one spot and moment. It is only in the very long run that its effects become perceptible. Reason assumes to settle things by weighing them against one another without prejudice, partiality, or excitement; but what affairs in the concrete are settled by is and always will be just prejudices, partialities, cupidities, and excitements. Appealing to reason as we do, we are in a sort of a forlorn hope situation, like a small sand-bank in the midst of a hungry sea ready to wash it out of existence. But sand-banks grow when the conditions favor; and weak as reason is, it has the unique advantage over its antagonists that its activity never lets up and that it presses always in one direction, while men's prejudices vary, their passions ebb and flow, and their excitements are intermittent. Our sand-bank, I absolutely believe, is bound to grow,—bit by bit it will get dyked and breakwatered. But sitting as we do in this warm room, with music and lights and the flowing bowl and smiling faces, it is easy to get too sanguine about our task, and since I am called to speak, I feel as if it might not be out of place to say a word about the strength of our enemy.
Our permanent enemy is the noted bellicosity of human nature. Man, biologically considered, and whatever else he may be in the bargain, is simply the most formidable of all beasts of prey, and, indeed, the only one that preys systematically on its own species. We are once for all adapted to the military status. A millennium of peace would not breed the fighting disposition out of our bone and marrow, and a function so ingrained and vital will never consent to die without resistance, and will always find impassioned apologists and idealizers.
Not only men born to be soldiers, but non-combatants by trade and nature, historians in their studies, and clergymen in their pulpits, have been war's idealizers. They have talked of war as of God's court of justice. And, indeed, if we think how many things beside the frontiers of states the wars of history have decided, we must feel some respectful awe, in spite of all the horrors. Our actual civilization, good and bad alike, has had past war for its determining condition. Great-mindedness among the tribes of men has always meant the will to prevail, and all the more so if prevailing included slaughtering and being slaughtered. Rome, Paris, England, Brandenburg, Piedmont, —soon, let us hope, Japan,—along with their arms have made their traits of character and habits of thought prevail among their conquered neighbors. The blessings we actually enjoy, such as they are, have grown up in the shadow of the wars of antiquity. The various ideals were backed by fighting wills, and where neither would give way, the God of battles had to be the arbiter. A shallow view, this, truly; for who can say what might have prevailed if man had ever been a reasoning and not a fighting animal? Like dead men, dead causes tell no tales, and the ideals that went under in the past, along with all the tribes that represented them, find to-day no recorder, no explainer, no defender.
But apart from theoretic defenders, and apart from every soldierly individual straining at the leash, and clamoring for opportunity, war has an omnipotent support in the form of our imagination. Man lives by habits, indeed, but what he lives for is thrills and excitements. The only relief from Habit's tediousness is periodical excitement. From time immemorial wars have been, especially for non-combatants, the supremely thrilling excitement. Heavy and dragging at its end, at its outset every war means an explosion of imaginative energy. The dams of routine burst, and boundless prospects open. The remotest spectators share the fascination. With that awful struggle now in progress on the confines of the world, there is not a man in this room, I suppose, who doesn't buy both an evening and a morning paper, and first of all pounce on the war column.
