The present dangers which must be eliminated somehow lest we all stagger on to catastrophe are of three kinds: racial, social, and economic. The last indeed is of such overwhelming influence upon racial rivalries and social upheavals, that many students of modern history are inclined to believe that it is the underlying meaning of all wars, revolutions, and human struggles. The pressure of population, the need of food, the desire to get raw material for industrial manufactures, national competition to capture trade markets, are, according to the modern school of thought, the main causes of international friction and explosive episodes. I agree as to the terrific importance of economic facts, especially in this present time of history, when the world has been industrialised, but there are other instincts in the human heart beyond the need of food, other passions besides trade rivalry. The passion of race is one of them. The passion of liberty for the race or nation is intense. National pride, sentiment expressed in symbols, such as the Flag, religious fanaticism, such as that of Islam, set human hearts on fire and make them careless even of self interest or self preservation. Before looking at the economic struggle which is looming ahead, and in my opinion is going to be a possible cause of another world conflict, one may see signs of racial passion stirring in many parts of the world and threatening its future peace. RACIAL PASSIONS It is in the very heart of Europe. Certainly the majority of the German people refuse stubbornly to accept the consequences of the defeat inflicted upon them as more than a temporary check to their strength and supremacy among civilised people. They are so conscious of their own genius in organisation and industry, so confident in the future destiny of the German folk, so sure that their increasing population is bound to prevail over the weaker and dwindling stock of a nation like France, that they are only waiting for the time when, as they think, the inevitable laws of history will carry them in a tide over the present barriers that have been imposed upon them. Meanwhile, they rage at the humiliations they have to suffer, and brood over the injustice of their present condition. Their sense of being the victims of world injustice is a fixed idea or what, in the present jargon of psycho-analysis, is called a “complex.” It is not less dangerous for that, and to regain their liberty of action, freedom from foreign interference with foreign occupation, and release from immense burdens of foreign debt, there are large numbers of Germans who would willingly die with a racial patriotism and passion exalted above all self-interest. Many old women in Germany would like to march with sharpened scissors behind the German troops. Many young girls would gladly go with their hatpins to stab a Frenchman or two in revenge for the Ruhr. Europe will not be safe until that racial hatred between
