Kelsen's Theory of International Law
Among legal philosophers, the time-honored dispute between natural-law schools and legal positivists arouses ever new interest. On the side of the positivists, the “pure theory of law” gains more and more ground. This theory is mainly represented by Professor Hans Kelsen, formerly of Vienna, now of Geneva, and by Professor Alfred von Verdross, of Vienna. In America, systematic consideration was first devoted to it by Dr. Johannes Mattern, who analyzed Verdross's thinking; later, Dr. Josef L. Kunz, one of the foremost followers of Kelsen, took up the discussion, emphasizing the importance of the theory for a scientific basis of international law; and quite recently an article by Dr. Henry Janzen dealt with legal monism as the basis of the “pure theory of law.”
