Kelsen, Hans


Born Oct. 11, 1881, in Prague. Austrian jurist.

Kelsen was a professor at the University of Vienna from 1917 to 1929, the University of Cologne from 1929 to 1933, and the University of Geneva from 1933 to 1940. In 1940 he emigrated to the USA and in 1942 became a professor at the University of California. He was one of the founders of the normative school of law, which is sometimes called the Vienna school or the pure study of law. Kelsen believes that juridical science ought to reject entirely the study of law as a function of society and economics or as a servant of political, moral, historical, or other “metajuridical” aims. In his view, law should be studied in its “pure” aspect, strictly as a legal form. Otherwise, Kelsen maintains, the science of law loses its objective character and turns into ideology.

Kelsen was one of the first to propagate the slogan “deideologization of science,” which is widely held in bourgeois science. For the methodological foundation of his “pure” approach to law, Kelsen used the neo-Kantian opposition of “ought” and “is” as phenomena lying, as it were, in different planes and having no contact. The norm of a law, which establishes what ought to be done, is in Kelsen’s view independent of the real world and can be extracted only from another, broader norm. Kelsen constructs a closed hierarchical system of legal norms issuing from some presumed source, the hypothetical “basic norm.” From this construction, he arrives at an idea actively used in the bourgeois science of international law: the primacy of international law over intrastate law and the denial of the principle of sovereignty. Kelsen looks upon the state not as the force creating law but as something derived from law, as the “personification of the legal order.”

Kelsen’s teachings reflect the striving of bourgeois jurisprudence during the general crisis of capitalism to put aside the aggravated contradictions of capitalist reality and present the norms of bourgeois law as obvious logical imperatives. During the 1950’s, Kelsen wrote several works devoted to the Marxist theory of law, in which socialist legal theory and practice are examined from a position of active anticommunism.
