The call to arms is one thing; the actual fighting, which converts men, to use his own phrase, into "devils and butchers," is another. The call to arms awakes something in a man more heroic than the life he ordinarily lives; he seems to hear in it the voice of the Nation calling him by name, and when he answers he feels the joy of the Nation in his heart. He becomes consciously one with a great host in the hour of peril. He hears the voice of a Cause in the bugles and the drums. He shares in a new emotion, which is his glory because it is not his alone. He finds a fuller liberty than he has ever known in the discipline of the ranks; he accepts the petty tyrannies to which he is subjected, feeling that behind the officers is the will of the Nation to which he has yielded his own. This, for better and worse, we may call the mysticism of war, and it appealed forcibly to Whitman. For him, war was illuminated by the idea of solidarity; an idea which was constantly present to him from this time forward. He no longer saw the great personalities only, nor only their divine comradeship in the life of God; all that remained as vivid as of old; but now he was being constantly reminded of the way in which individuals share consciously in the life of the nation; and this suggested to him how, presently, they will come to be conscious of their part in the life of the Race. He recognised how essential was the sense of citizenship to fuller soul-life. The barriers in which our individual lives are isolated must be broken, if liberty is to be brought to the soul. If we are to live fully, we must feel the tides of being sweep through our emotional natures. Hence his welcome to war, which, in spite of all the fiendish spirits which follow in its wake, does thrill a chord of national consciousness in the individual heart. We may well ask whether there is no errand worthier of this sense of solidarity than that of slaughter. Surely the affirmation of such an errand underlies the whole thought of _Drum-taps_, with its call to a "divine war".[428] The hour has come when the Social Passion is about to rouse the peoples to a nobler crusade against oppression than any yet; when the nations shall be purged by revolutions wholesomer than those of 1789 or 1861. Whitman's whole life, throbbing in every page he wrote, proclaims it.
