proposition, its character would enable one to suspect it of being the utterance of a soldier rather than a biologist. There is about it a confidence that the vital effects of war are simple and easy to define and a cheerful contempt for the considerable biological difficulties of the subject that remind one of the bracing military atmosphere, in which a word of command is the supreme fact, rather than that of the laboratory, {127} where facts are the masters of all. It may be supposed that even in the country of its birth the doctrine seemed more transcendently true in times of peace amid a proud and brilliant regime than it does now after more than twelve months of war. The whole conception is of a type to arouse interest in its psychological origin rather than in a serious discussion of its merits. It arose in a military State abounding in prosperity and progress of very recent growth, and based upon three short wars which had come closely one after another and formed an ascending series of brilliant success. In such circumstances even grosser assumptions might very well flourish and some such doctrine was a perfectly natural product. The situation of the warrior-biologist was in some way that of the orthodox expounder of ethics or political economy—his conclusions were ready-made for him; all he had to do was to find the “reasons” for them. War and war only had produced the best and greatest and strongest State—indeed, the only State worthy of the name; therefore war is the great creative and sustaining force of States, or the universe is a mere meaningless jumble of accidents. If only wars would always conform to the original Prussian pattern, as they did in the golden age from 1864 to 1870—the unready adversary, the few pleasantly strenuous weeks or months, the thumping indemnity! That is the sort of biological necessity one can understand. But twelve months of agonizing, indecisive effort in Poland and Russia and France, might have made the syllogism a little less perfect, the new law of Nature not quite so absolute.
These matters, however, are quite apart
