This democratic spirit is the real power behind internationalism. It is as the mood of the city, the whole spirit of the modern urban life, that it is most significant. The mood of the city contains on one side the possibility of an internationalism which is nothing more than a surrender of all patriotism, and is at heart only a mass interest in rights and needs. On the other hand all the interests and impulses that make internationalism necessary and possible seem to have their origin in the city. The city represents, with all its evil, the higher life and the line of progress. Progress passes through the city. The city is the symbol of creativeness and achievement. Industrialism, the essential spirit of the city, is the condition, normal and necessary we must conclude, out of which the necessity of international order arises. It is a phase of the process by which nations become dependent upon one another by being specialized and becoming densely populated. It is also a factor in the cause of wars without and revolutions within. The mood of the city is thus in a sense the essence of life, but it is also the source of disease and death in the national life. It is the price that is paid for civilization that the city tends to become the hardened artery of national life. The control of the city moods by educational forces we may believe is one of the most fundamental of all the problems of conscious evolution. It is the control at the fountain-head of the forces out of which internationalism is to be made that we undertake when we try to educate the life of the city, with reference to its good and its evil. The too rapid urbanizing of the life of nations, the production, in the cities, of powers too great and too rapidly growing to be controlled by the civilizing forces in a country is the great danger in modern life. So great indeed are the dangers in the accelerated growth of industrialism in all the great countries and the increased specialization in the industrial life, that something radical must be done, in our view, to counterbalance this movement, and especially to control and to raise to higher levels the psychic factors of city life.
