these interests, and the deep, true, underlying harmonies of interest between peoples, which the prophets of Free Trade dimly perceived, will manifest themselves, and the necessity of permanent industrial warfare between nations will be recognised as an illusion analogous in nature and origin to the illusion of the biological necessity of war.
The struggle for life is indeed a permanent factor in social progress, selection of the physically fit is a necessity, but as men become more rational they rationalise the struggle, substituting preventive for destructive methods of selection, and raising the standard of fitness from a crudely physical robustness to one which maintains physical endurance as the raw material of higher psychical activities. Thus, while men no longer fight for food, their personal fitness is maintained, the struggle and the fitness are both raised to a higher plane. If this can take place in the struggle of individuals, it can take place in the struggle of nations. The economy of internationalism is the same as that of nationalism. As individuality does not disappear but is raised and quickened by good national government, so nationality does not disappear but is raised and quickened by internationalism.
