The war of 1870, brought about by the third Napoleon's half-generous, half-selfish adoption of the principle of nationalities, was the first war characterised by a special intensity of hate, by a new note in the tune of an old song for which we may thank the Teutonic thoroughness. Was it not that excellent bourgeoise, Princess Bismarck (to keep only to great examples), who was so righteously anxious to see men, women and children--emphatically the children, too--of the abominable French nation massacred off the face of the earth? This illustration of the new war- temper is artlessly revealed in the prattle of the amiable Busch, the Chancellor's pet "reptile" of the Press. And this was supposed to be a war for an idea! Too much, however, should not be made of that good wife's and mother's sentiments any more than of the good First Emperor William's tears, shed so abundantly after every battle, by letter, telegram, and otherwise, during the course of the same war, before a dumb and shamefaced continent. These were merely the expressions of the simplicity of a nation which more than any other has a tendency to run into the grotesque. There is worse to come. To-day, in the fierce grapple of two nations of different race, the short era of national wars seems about to close. No war will be waged for an idea. The "noxious idle aristocracies" of yesterday fought without malice for an occupation, for the honour, for the fun of the thing. The virtuous, industrious democratic States of to-morrow may yet be reduced to fighting for a crust of dry bread, with all the hate, ferocity, and fury that must attach to the vital importance of such an issue. The dreams sanguine humanitarians raised almost to ecstasy about the year fifty of the last century by the moving sight of the Crystal Palace--crammed full with that variegated rubbish which it seems to be the bizarre fate of humanity to produce for the benefit of a few employers of labour--have vanished as quickly as they had arisen. The golden hopes of peace have in a single night turned to dead leaves in every drawer of every benevolent theorist's writing table. A swift disenchantment overtook the incredible infatuation which could put its trust in the peaceful nature of industrial and commercial competition.
