Several writers, but especially Le Bon (42), have written about the relation of mysticism to war. Le Bon said indeed that the main causes of war, including the most recent one, are mystical causes. By mysticism he means unconscious factors which are religious in quality and which contain a race ideal which is both powerful and irrational. German mysticism appears to have attracted much attention during the years of the war. Germany has presented the picture, we are told, of a people becoming dangerous by couching national ambition and honor in terms of religion. This mysticism of the German contains a powerful belief in race superiority, and in the supremacy of the culture of their own nation, beliefs which have the clear marks of mysticism about them. The traces of the theory of divine origin still cling to them. Boutroux (13) says the Prussian State is a synthesis of the divine and the human. Another writer observes that the Germans believe in the altogether unique and quasi-divine excellence of the German race, and of Germanism, and that the Germans have a new religion which they believe in spreading by the sword. Some see in Germany a serious demand for the revival of the religion of Odin and Thor, the religion of conflict of primeval forces, and of the triumph of might. Literary expressions of this religion are certainly to be found, and it may fairly be maintained that Germany has never become Christianized to the extent that most modern nations have. That mysticism has been a large factor in the war spirit of the Germans in the late war can hardly be doubted, or at least that a religious element of some kind has played a great part in it. The war began as Germany's holy war. A cult of State and of self-worship are involved in it. If not, innumerable expressions of Germany's cause among German writers are simply literary exaggerations. The Germans have believed that they are God's chosen people, that they represent God, and since the German civilization grew up in antagonism to the Graeco-Roman civilization, God must have adopted the one and discarded the other. One German writer says that we must eliminate from our belief the last drop of faith in the idea of a progressive movement of humanity as a whole. Reality is represented in one nation at a time, and the chosen nation is the leader of all the rest.
