Hans Kelsen and the Natural Law Tradition provides the first sustained examination of Hans Kelsen’s critical engagement, itself founded upon a distinctive theory of legal positivism, with the Natural Law Tradition. This edited collection commences with a comprehensive introduction which establishes the character of Kelsen’s critical engagement as a general critique of natural law combined with a more specific critique of representative thinkers of the Natural Law Tradition. The subsequent chapters are then devoted to a detailed analysis of Kelsen’s engagement with prominent theorists from the Natural Law Tradition. The volume concludes with an exploration, focusing upon the delineation of a non-positivist legal theory in the debate between Robert Alexy and Joseph Raz, of the continued presence of Kelsenian legal positivism in contemporary legal theory.

Reprint of the second revised and enlarged edition, a complete revision of the first edition published in 1934. A landmark in the development of modern jurisprudence, the pure theory of law defines law as a system of coercive norms created by the state that rests on the validity of a generally accepted Grundnorm, or basic norm, such as the supremacy of the Constitution. Entirely self-supporting, it rejects any concept derived from metaphysics, politics, ethics, sociology, or the natural sciences. Beginning with the medieval reception of Roman law, traditional jurisprudence has maintained a dual system of "subjective" law (the rights of a person) and "objective" law (the system of norms). Throughout history this dualism has been a useful tool for putting the law in the service of politics, especially by rulers or dominant political parties. The pure theory of law destroys this dualism by replacing it with a unitary system of objective positive law that is insulated from political manipulation. Possibly the most influential jurisprudent of the twentieth century, Hans Kelsen [1881-1973] was legal adviser to Austria's last emperor and its first republican government, the founder and permanent advisor of the Supreme Constitutional Court of Austria, and the author of Austria's Constitution, which was enacted in 1920, abolished during the Anschluss, and restored in 1945. The author of more than forty books on law and legal philosophy, he is best known for this work and General Theory of Law and State. Also active as a teacher in Europe and the United States, he was Dean of the Law Faculty of the University of Vienna and taught at the universities of Cologne and Prague, the Institute of International Studies in Geneva, Harvard, Wellesley, the University of California at Berkeley, and the Naval War College. Also available in cloth.

This book critically examines the conception of legal science and the nature of law developed by Hans Kelsen. It provides a single, dedicated space for a range of established European scholars to engage with the influential work of this Austrian jurist, legal philosopher, and political philosopher. The introduction provides a thematization of the Kelsenian notion of law as a legal science. Divided into six parts, the chapter contributions feature distinct levels of analysis. Overall, the structure of the book provides a sustained reflection upon central aspects of Kelsenian legal science and the nature of law. Parts one and two examine the validity of the project of Kelsenian legal science with particular reference to the social fact thesis, the notion of a science of positive law and the specifically Kelsenian concept of the basic norm (Grundnorm). The next three parts engage in a critical analysis of the relationship of Kelsenian legal science to constitutionalism, practical reason, and human rights. The last part involves an examination of the continued pertinence of Kelsenian legal science as a theory of the nature of law with a particular focus upon contemporary non-positivist theories of law. The conclusion discusses the increasing distance of contemporary theories of legal positivism from a Kelsenian notion of legal science in its consideration of the nature of law.

Using newly translated papers and some of the best extant writings on Kelsen's theory, this volume covers topics including competing ideas on the nature of law, legal validity, legal powers and the unity of municipal and international law.

Reprint of the first edition. This classic work by the important Austrian jurist is the fullest exposition of his enormously influential pure theory of law, which includes a theory of the state. It also has an extensive appendix that discusses the pure theory in comparison with the law of nature, positivism, historical natural law, metaphysical dualism and scientific-critical philosophy. "The scope of the work is truly universal. It never loses itself in vague generalities or in unconnected fragments of thought. On the contrary, precision in the formulation of details and rigorous system are characteristic features of the exposition: only a mind fully concentrated upon that logical structure can possibly follow Kelsen's penetrating analysis. Such a mind will not shrink from the effort necessary for acquainting itself with...the pure theory of law in its more general aspects, and will then pass over to the theory of the state which ends up with a carefully worked out theory of international law." Julius Kraft, American Journal of International Law 40 (1946):496.

First published in 1998.This is Volume XIV of eighteen in the Sociology of Behaviour and Psychology series. This text is concerned with sociological inquiry into society and nature. Written in 1946, it investigates the idea that society and nature, if conceived of as two different systems of elements, are the results of two different methods of thinking and are only as such two different objects. The same elements, connected with each other according to the principle of causality, constitute nature; connected with each other according to another, namely, a normative, principle, they constitute society

By showing how Kelsen's theory of law works alongside his political philosophy, the book shows the Pure Theory to be part of a wider attempt to understand how political power can be legitimately exercised in pluralist societies.

New. $95. * Through the lens of science, Kelsen proposes a dynamic theory of natural law, examines Platonic and Aristotelian doctrines of justice, the idea of justice as found in the holy scriptures, and defines justice as "...that social order under whose protection the search for truth can prosper. 'My' justice, then, is the justice of freedom, the justice of peace, the justice of democracy-the justice of tolerance." (p. 24).

This analysis of Hans Kelsen's international law theory takes into account the context of the German international legal discourse in the first half of the twentieth century, including the reactions of Carl Schmitt and other Weimar opponents of Kelsen. The relationship between his Pure Theory of Law and his international law writings is examined, enabling the reader to understand how Kelsen tried to square his own liberal cosmopolitan project with his methodological convictions as laid out in his Pure Theory of Law. Finally, Jochen von Bernstorff discusses the limits and continuing relevance of Kelsenian formalism for international law under the term of 'reflexive formalism', and offers a reflection on Kelsen's theory of international law against the background of current debates over constitutionalisation, institutionalisation and fragmentation of international law. The book also includes biographical sketches of Hans Kelsen and his main students Alfred Verdross and Joseph L. Kunz.

Hans Kelsen is considered by many to be the foremost legal thinker of the twentieth century. During the last decade of his life he was working on what he called a general theory of norms. Published posthumously in 1979 as Allgemeine Theorie der Normen, the book is here translated for the first time into English. Kelsen develops his "pure theory of law" into a "general theory of norms", and analyzes the applicability of logic to norms to offer an original and extreme position which some have called "normative irrationalism". Examining the views of over 200 philosophers and legal theorists on law, morality, and logic, and revising several of his own earlier positions, Kelsen's final work is a mandatory resource for legal and moral philosophers.
