(4) The supremacy of personality is a principle of life that conflicts today with the current emphasis on economic efficiency. It is because the latter is so often reckless of human values that the new social order will stress the development of things of the spirit rather than material goods; even business must practice this ideal. The World War raised the estimate which the common people put on their own lives; but the ultimate result will depend on whether or not people took part in the war voluntarily and conscious of high moral purposes, and whether or not the peace which follows shall bring a new world organization that conserves all the advances in human living that have thus far been made. Institutions possess an inherent fallibility. They tend to become mechanical and repressive, even those dedicated to high purposes, such as institutions of democracy, of education, and of religion. The supreme object of any social institution and organization, no matter in what field it may exist, should be the increase of personality.[XXVI-50] (5) The new social order will be governed by a sense of solidarity, that is, by a community of feeling and thought which arises when individuals associate together in working for a common end. World solidarity will come when all peoples learn to work together for public welfare, and subordinate all selfish desires to this end. Christianity is moving in this direction when it advances the concept of “comradeship of all men with each other and with the Great Companion,” when it gradually unfolds the idea of a unified world life, when it applies its doctrines of brotherhood of man to the relations of the employer and employee or to the relations of white and black races, when it seeks the democratic solidarity of the human race rather than the imperialistic solidarity of an overhead religious control, when it endeavors to spread love and faith, rather than to spread dogmas and promote organizations.[XXVI-51] Class cleavage, nationalism as distinct from nationality, race prejudice, ignorance, and selfishness are the main opponents of the world brotherhood principle.
