Turn the fear over as I will in my mind, it all seems to lead back to two unwillingnesses of the imagination, one aesthetic, and the other moral; unwillingness, first to envisage a future in which army-life, with its many elements of charm, shall be forever impossible, and in which the destinies of peoples shall nevermore be decided, quickly, thrillingly, and tragically, by force, but only gradually and insipidly by "evolution"; and, secondly, unwillingness to see the supreme theatre of human strenuousness closed, and the splendid military aptitudes of men doomed to keep always in a state of latency and never show themselves in action. These insistent unwillingnesses, no less than other aesthetic and ethical insistencies, have, it seems to me, to be listened to and respected. One cannot meet them effectively by mere counter-insistency on war's expensiveness and horror. The horror makes the thrill; and when the question is of getting the extremest and supremest out of human nature, talk of expense sounds ignominious. The weakness of so much merely negative criticism is evident--pacificism makes no converts from the military party. The military party denies neither the bestiality nor the horror, nor the expense; it only says that these things tell but half the story. It only says that war is _worth_ them; that, taking human nature as a whole, its wars are its best protection against its weaker and more cowardly self, and that mankind cannot _afford_ to adopt a peace-economy.
