The conditions preceding our recent great war will doubtless in the course of future historical and sociological research, be minutely scrutinized, in the effort to find the causes of the war--factors deeper than and different from the political and economic causes and the personal intrigues that are now most emphasized. If we believe that the war was made in Germany rather than elsewhere, we might look there, especially for these psychological factors of war--for our intoxication motives and unconscious impulses and our causes of reversion, but we should probably not find anything different in kind there from what we should discover in other great countries. Those who have seen in modern industrialism dangers of coming disaster, or who now look back upon it as a genuine cause of the war were probably not mistaken. Industrialism has been producing rapidly, and in an intense form, what we may call the mood of the city, and this mood of the city contains all the conditions and all the emotions that tend to bring to the surface the deep-lying motives of the social life that we are trying to point out. There are both the joy of the abundant life, the craving for new experiences, and the sense of reality, and also the disorganization of interests and motives, the stress and fatigue and monotony which prepare the mind for culmination in dramatic events. There is, in a word, a deep stirring of all the forces that make for progress and expansion, and also conditions that disorganize the individual and the social life. Lamprecht (59) of all German writers seems to have appreciated this. He has written before the war, describing a condition in Germany which he says began in the seventies of the preceding century--a change of German life in which there is a great increase of the activities of the cities, with haste and anxiety, unscrupulous individual energy, general nervous excitement, a condition of neuro-muscular weakness (and he might have added as another sign, over-stimulation of the mind by a great flood of morbid literature).
