There can be little doubt that these several minds and spirits, stirred by the passion and energy of war, and reacting sensitively both to its cruelties and to its pities, have experienced the kinship of quickened insight and finer unselfishness in the face of wide-ranging death. They have silently compared, perhaps, the normal materialistic conventions in business, politics, education, and religion, with the relief from those conventions that nearly all soldiers and many civilians experience in time of war; for although war has its too gross and ugly side, it has not dared to learn that inflexibility of custom and conduct that deadens the spirit into a tame submission. This strange rebound and exaltation would seem to be due less to the physical realities of war--which must in many ways cramp and constrain the individual--than to the relative spiritual freedom engendered by the needs of war, if they are to be successfully met. The man of war has an altogether unusual opportunity to realize himself, to cleanse and heal himself through the mastering of his physical fears; through the facing of his moral doubts; through the reëxamination of whatever thoughts he may have possessed, theretofore, about life and death and the universe; and through the quietly unselfish devotion he owes to the welfare of his fellows and to the cause of his native land. Into the stuff of his thought and utterance, whether he be on active service or not, the poet-interpreter of war weaves these intentions, and coöperates with his fellows in building up a little higher and better, from time to time, that edifice of truth for whose completion can be spared no human experience, no human hope.
