Long feared and long foretold, yet never seriously expected, the European War came at last. Nations, great and small, arose in their strength, and gathered, in an avalanche of excitement, all their manhood to battle, all their old age to guard, and all their womanhood, not only as in bygone days, to tend and heal the wounded and sick, but also to do preparatory work for the fighting armies. Generations, young and old, rushed eagerly to defend their countries, leaving home, property, calling; knowing no fear save that here and there one of their fellow-citizens might prove less patriotic than themselves. The world was thrown back to the moral level and the ethical conceptions of thousands of years ago: man became again a wolf to man, as in the Pleistocene Age. On the one hand, the vast and bloody epic produced a sort of ecclesiastical moratorium which, for the duration of the war, annulled all moral obligations and abrogated the Ten Commandments, while on the other hand, it developed, to the highest degree, all the great and noble feelings――sense of honour, unselfishness, magnanimity, courage. Nationality, patriotism, the sense of duty, the spirit of sacrifice, enthusiastic heroism and patriotic martyrdom filled the hearts and created a new atmosphere, in which every kind of human activity was intensified: industry, art, science, and literature. This great storm, the greatest storm that had ever stirred mankind, produced the greatest spiritual tragedy the world has ever known. The most terrible aspect of the war was not the fact that Europe was being bled white, that all the amenities of civilization were breaking down with the strain of the military operations, and that each day some new and more brutal engine of destruction was prepared and brought into use, but――the ethical conflict carried on with minds and nerves on the rack of tense emotion which not only upset mental balance and changed the outlook of peoples, hitherto industrious and peaceful, but developed moral and social fears and passions which will not pass away in a day. This universal catastrophe would indeed have degraded the world into “a sort of malign middle term between a lunatic asylum and a butcher’s stall,” if it had not finally become――as it has become――“a war against war.” The peoples turned their ploughshares into swords, they ceased to make useful, beneficial rails and plates and angles and girders of their iron ore and their coal, and they manufactured harmful, destructive shells and guns to project them to the slaughter of the enemy, hoping that when the time came they would again turn their swords into ploughshares. They realized that the enemy of society is militarist despotism, and that militarist despotism therefore must be ended, or it will end society. A great moral idea arose out of this war: the liberation of oppressed small nations. Another great moral idea arising from it is the de-militarization of humanity. The whole
