It is only by some such admission, embodying itself in a Parliament of the nations with full power to alter the distribution of territory, that militarism can be permanently overcome. It may be that the present war will bring, in the Western nations, a change of mood and outlook sufficient to make such an institution possible. It may be that more wars and more destruction will be necessary before the majority of civilized men rebel against the brutality and futile destruction of modern war. But unless our standards of civilization and our powers of constructive thought are to be permanently lowered, I cannot doubt that, sooner or later, reason will conquer the blind impulses which now lead nations into war. And if a large majority of the Great Powers had a firm determination that peace should be preserved, there would be no difficulty in devising diplomatic machinery for the settlement of disputes, and in establishing educational systems which would implant in the minds of the young an ineradicable horror of the slaughter which they are now taught to admire. Besides the conscious and deliberate forces leading to war, there are the inarticulate feelings of common men, which, in most civilized countries, are always ready to burst into war fever at the bidding of statesmen. If peace is to be secure, the readiness to catch war fever must be somehow diminished. Whoever wishes to succeed in this must first understand what war fever is and why it arises. The men who have an important influence in the world, whether for good or evil, are dominated as a rule by a threefold desire: they desire, first, an activity which calls fully into play the faculties in which they feel that they excel; secondly, the sense of successfully overcoming resistance; thirdly, the respect of others on account of their success. The third of these desires is sometimes absent: some men who have been great have been without the “last infirmity,” and have been content with their own sense of success, or merely with the joy of difficult effort. But as a rule all three are present. Some men’s talents are specialized, so that their choice of activities is circumscribed by the nature of their faculties; other men have, in youth, such a wide range of possible aptitudes that their choice is chiefly determined by the varying degrees of respect which public opinion gives to different kinds of success.
