Written toward the end of World War I, this study of economics tackles the issue from the standpoint of religion and philosophy by summarizing the Catholic school of economics, which insists that the welfare of human beings belongs at the center of any real economy and that other systems that place either the individual or the state at the center of their schemes are not only false, but actually injurious to individuals, families, communities, and nations. Extensive documentation and citations from leading economic theorists are provided.
