The human mind is an instrument very easily fatigued. Only a few exceptions go on thinking restlessly--to the extreme exasperation of their neighbours. The normal mind craves for decisions, even wrong or false decisions rather than none. It clutches at comforting falsehoods. It loves to be told, “_There_, don't you worry. That'll be all right. That's _settled._” This war has come as an almost overwhelming challenge to mankind. To some of us it seems as it if were the Sphynx proffering the alternative of its riddle or death. Yet the very urgency of this challenge to think seems to paralyse the critical intelligence of very many people altogether. They will say, “This war is going to produce enormous changes in everything.” They will then subside mentally with a feeling of having covered the whole ground in a thoroughly safe manner. Or they will adopt an air of critical aloofness. They will say, “How is it possible to foretell what may happen in this tremendous sea of change?” And then, with an air of superior modesty, they will go on doing--whatever they feel inclined to do. Many others, a degree less simple in their methods, will take some entirely partial aspect, arrive at some guesswork decision upon that, and then behave as though that met every question we have to face. Or they will make a sort of admonitory forecast that is conditional upon the good behaviour of other people. “Unless the Trade Unions are more reasonable,” they will say. Or, “Unless the shipping interest is grappled with and controlled.” Or, “Unless England wakes up.” And with that they seem to wash their hands of further responsibility for the future. One delightful form of put-off is the sage remark, “Let us finish the war first, and then let us ask what is going to happen after it.” One likes to think of the beautiful blank day after the signing of the peace when these wise minds swing round to pick up their deferred problems....
