"The chief causes of large-scale violence are: love of power, competition, hate and fear. Love of power will have no national outlet when all serious military force is concentrated in the international army. Competition will be effectively regulated by law, and mitigated by governmental controls. Fear — in the acute form in which we know it — will disappear when war is no longer to be expected. There remains hate and malevolence. This has a deep hold on human nature. We all believe at once any gossip discreditable to our neighbors, however slender the evidence may be. … I am persuaded that it can be lessened, and very quickly. If peace becomes secure there will be a very rapid increase of material prosperity, and this tends more than anything else to provide a mood of kindly feeling. Consider the immense diminution of cruelty in Britain during the Victorian Age; this was mainly due to rapidly increasing wealth in all classes. I think we may confidently expect a similar effect throughout the world owing to the increased wealth that will result from the elimination of war."
