" Sensible men, however, really had very little to do with it. The war itself did not make very much sense, which may have affected the way it was directed. It was being fought because emotion had been evoked to deal with a crisis that called for intelligence. There had been the great argument between men and sections, with many old values endangered, and on each side there had arisen men with blazing eyes and hot hearts to arouse their fellows to imminent peril. Fear had been called forth (because it is thought that men are most surely to be aroused by fear), and then came the anger that goes with fear, and finally the great unreason that goes with both had come out to take control of things—a situation deeply lamented by all who had created it.
