Like all social theories, internationalism must seek its basis in the economic and technical fields; here are to be found the most profound and the most decisive factors in the development of society.

In particular, the efforts to reestablish peace after the World War have been directed toward the formation of states and the regulation of their frontiers according to a consciously national program.

Technology is a useful servant but a dangerous master.
