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.

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.

Social norms are rules that prescribe what people should and should not do given their social surroundings and circumstances. Norms instruct people to keep their promises, to drive on the right, or to abide by the golden rule. They are useful explanatory tools, employed to analyze phenomena as grand as international diplomacy and as mundane as the rules of the road. But our knowledge of norms is scattered across disciplines and research traditions, with no clear consensus on how the term should be used. Research on norms has focused on the content and the consequences of norms, without paying enough attention to their causes. Social Norms reaches across the disciplines of sociology, economics, game theory, and legal studies to provide a well-integrated theoretical and empirical account of how norms emerge, change, persist, or die out. Social Norms opens with a critical review of the many outstanding issues in the research on norms: When are norms simply devices to ease cooperation, and when do they carry intrinsic moral weight? Do norms evolve gradually over time or spring up spontaneously as circumstances change? The volume then turns to case studies on the birth and death of norms in a variety of contexts, from protest movements, to marriage, to mushroom collecting. The authors detail the concrete social processes, such as repeated interactions, social learning, threats and sanctions, that produce, sustain, and enforce norms. One case study explains how it can become normative for citizens to participate in political protests in times of social upheaval. Another case study examines how the norm of objectivity in American journalism emerged: Did it arise by consensus as the professional creed of the press corps, or was it imposed upon journalists by their employers? A third case study examines the emergence of the norm of national self-determination: has it diffused as an element of global culture, or was it imposed by the actions of powerful states? The book concludes with an examination of what we know of norm emergence, highlighting areas of agreement and points of contradiction between the disciplines. Norms may be useful in explaining other phenomena in society, but until we have a coherent theory of their origins we have not truly explained norms themselves. Social Norms moves us closer to a true understanding of this ubiquitous feature of social life.

This book presents the concept of norms by four different philosophers. They discuss how norms emerge, persist, change, and how they serve to explain what we do.

Edna Ullmann-Margalit provides an original account of the emergence of norms. Her main thesis is that certain types of norms are possible solutions to problems posed by certain types of social interaction situations. The problems are such that they inhere in the structure (in the game-theoretical sense of structure) of the situations concerned. Three types of paradigmatic situations are dealt with. They are referred to as Prisoners' Dilemma-type situations; co-ordination situations; and inequality (or partiality) situations. Each of them, it is claimed, poses a basic difficulty, to some or all of the individuals involved in them. Three types of norms, respectively, are offered as solutions to these situational problems. It is shown how, and in what sense, the adoption of these norms of social behaviour can indeed resolve the specified problems.

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.

This book proposes the study of norms as a method of explaining human choice and behaviour by introducing a new scientific perspective. The science of norms may here be broadly understood as a social science which includes elements from both the behavioural and legal sciences. It is given that a science of norms is not normative in the sense of prescribing what is right or wrong in various situations. Compared with legal science, sociology of law has an interest in the operational side of legal rules and regulation. This book develops a synthesizing social science approach to better understand societal development in the wake of the increasingly significant digital technology. The underlying idea is that norms as expectations today are not primarily related to social expectations emanating from human interactions but come from systems that mankind has created for fulfilling its needs. Today the economy, via the market, and technology via digitization, generate stronger and more frequent expectations than the social system. By expanding the sociological understanding of norms, the book makes comparisons between different parts of society possible and creates a more holistic understanding of contemporary society. The book will be of interest to academics and researchers in the areas of sociology of law, legal theory, philosophy of law, sociology and social psychology.
