Christian nations if the path of aggression was at once easy, lucrative and safe? The judgments of nations in dealing with the aggressions of their neighbours are, it is true, very different from those which they form of aggressions by their own statesmen or for their own benefit. But no great nation is blameless, and there is probably no nation that could not speedily catch the infection of the warlike spirit if a conqueror and a few splendid victories obscured, as they nearly always do, the moral issues of the contest. War, it is true, is not always or wholly evil. Sometimes it is justifiable and necessary. Sometimes it is professedly and in part really due to some strong wave of philanthropic feeling produced by great acts of wrong, though of all forms of philanthropy it is that which most naturally defeats itself. Even when unjustifiable, it calls into action splendid qualities of courage, self-sacrifice, and endurance which cast a dazzling and deceptive glamour over its horrors and its criminality. It appeals too, beyond all other things, to that craving for excitement, adventure, and danger which is an essential and imperious element in human nature, and which, while it is in itself neither a virtue nor a vice, blends powerfully with some of the best as well as with some of the worst actions of mankind. It is indeed a strange thing to observe how many men in every age have been ready to risk or sacrifice their lives for causes which they have never clearly understood and which they would find it difficult in plain words to describe.
