A doctrine may be modern, fashionable, generally accepted and nevertheless detrimental to human society, civilization and survival. The first step to every attempt to investigate social, political, and economic changes has to be the study of the changes of the ideas which guided men to bring about these changes. The theories which build up or disintegrate social cooperation can only be proved or refuted by pure reasoning. They cannot be exposed to the simple examination of the experiment.
