"There can be little question that the attainment of a federation of all humanity, together with a sufficient measure of social justice, to ensure health, education, and a rough equality of opportunity to most of the children born into the world, would mean such a release and increase of human energy as to open a new phase in human history. The enormous waste caused by military preparation and the mutual annoyance of competing great powers, and the still more enormous waste due to the under-productiveness of great masses of people, either because they are too wealthy for stimulus or too poor for efficiency, would cease. There would be a vast increase in the supply of human necessities, a rise in the standard of life and in what is considered a necessity, a development of transport and every kind of convenience; and a multitude of people would be transferred from low-grade production to such higher work as art of all kinds, teaching, scientific research, and the like. All over the world there would be a setting free of human capacity, such as has occurred hitherto only in small places and through precious limited phases of prosperity and security. Unless we are to suppose that spontaneous outbreaks of supermen have occurred in the past, it is reasonable to conclude that the Athens of Pericles, the Florence of the Medici, Elizabethan England, the great deeds of Asoka, the Tang and Ming periods in art, are but samples of what a whole world of sustained security would yield continuously and cumulatively. Without supposing any change in human quality, but merely its release from the present system of inordinate waste, history justifies this expectation."
