In his introduction to these closely linked essays Professor Hart offers both an exposition and a critical assessment of some central issues in jurisprudence and political theory. Some of the essays touch on themes to which little attention has been paid, such as Bentham's identification of the forms of mysitification protecting the law from criticism; his relation to Beccaria; and his conversion to democratic radicalism and a passionate admiration for the United States.

According to the common thinking of continental European lawyers, a rule is invalid each and every time either it was not produced in accordance with the metarules which govern the production of rules in the system, or it is inconsistent with a “superior” (higher‐ranked) rule belonging to the same system. Thus, a better understanding of the concept of invalidity demands a careful inquiry into the various kinds of meta‐rules which govern the production of rules as well as into the various (...) kinds of normative hierarchies. The paper is mainly devoted to such an analysis. Five different grounds for invalidity are distinguished. The analysis further shows that invalidity can affect rules as well as legal provisions and legal sources. Further, invalidity should be sharply distinguished from non‐existence (existence being a sufficient condition for rules to be applied). In most legal systems, invalid rules too are susceptible of judicial application: At least, until their invalidity is “declared” (in a constitutive way) by a competent organ (namely, a constitutional court, as far as statutory rules are concerned).

One of the most interesting jurists of the post-World War II era, Ross [1899-1979] was a legal and moral philosopher, scholar of international law and the leading representative of Scandinavian Legal Realism. This book and On Law and Justice (1958) are (...) his principal works. In Directives and Norms Ross asks whether imperatives (or, to use his term, 'directives') are subject to logic in the same way as indicatives. He shows the difference between indicative and directive discourse and explains the concepts 'directive' and 'norm' as they function in the social sciences, especially in the study of law. A contemporary essay in the Modern Law Review (32:544), though critical of this work, was still impressed by its "clear and convincing account" of these processes. (shrink)

Practical Reason and Norms focuses on three problems: In what way are rules normative, and how do they differ from ordinary reasons? What makes normative systems systematic? What distinguishes legal systems, and in what consists their normativity? All three questions are answered by taking reasons as the basic normative concept, and showing the distinctive role reasons have in every case, thus paving the way to a unified account of normativity. Rules are a structure of reasons to perform the required act (...) and an exclusionary reason not to follow some competing reasons. Exclusionary reasons are explained, and used to unlock the secrets of orders, promises, and decisions as well as rules. Games are used to exemplify normative systems. Inevitably, the analysis extends to some aspects of normative discourse, which is truth-apt, but with a diminished assertoric force. (shrink)

The essays in this volume represent an approach to human knowledge that has had a profound influence on many recent thinkers. Popper breaks with a traditional commonsense theory of knowledge that can be traced back to Aristotle. A realist and fallibilist, he argues closely and in simple language that scientific knowledge, once stated in human language, is no longer part of ourselves but a separate entity that grows through critical selection.

The Concept of Law is the most important and original work of legal philosophy written this century. First published in 1961, it is considered the masterpiece of H.L.A. Hart's enormous contribution to the study of jurisprudence and legal philosophy. Its elegant language and balanced arguments have sparked wide debate and unprecedented growth in the quantity and quality of scholarship in this area--much of it devoted to attacking or defending Hart's theories. Principal among Hart's critics is renowned lawyer and political philosopher (...) Ronald Dworkin who in the 1970s and 80s mounted a series of challenges to Hart's Concept of Law. It seemed that Hart let these challenges go unanswered until, after his death in 1992, his answer to Dworkin's criticism was discovered among his papers. In this valuable and long-awaited new edition Hart presents an Epilogue in which he answers Dworkin and some of his other most influential critics including Fuller and Finnis. Written with the same clarity and candor for which the first edition is famous, the Epilogue offers a sharper interpretation of Hart's own views, rebuffs the arguments of critics like Dworkin, and powerfully asserts that they have based their criticisms on a faulty understanding of Hart's work. Hart demonstrates that Dworkin's views are in fact strikingly similar to his own. In a final analysis, Hart's response leaves Dworkin's criticisms considerably weakened and his positions largely in question. Containing Hart's final and powerful response to Dworkin in addition to the revised text of the original Concept of Law, this thought-provoking and persuasively argued volume is essential reading for lawyers and philosophers throughout the world.

This book makes two important contributions toward a general and systematic theory of rights-a powerful philosophical analysis of the language of rights and an explanation of the nature of rights. In working out these ideas, Wellman has provided a new and cohesive way of thinking and talking about rights of every sort. Wellman succeeds in bringing all kinds of rights-moral, legal, institutional, etc.-under one unified theory in a way that illuminates their similarities and differences. This enables him to deal in (...) a consistent way with a very broad range of philosophical questions, questions that are too often dealt with in isolation from each other. (shrink)

Bentham's best-known book stands as a classic of both philosophy and jurisprudence. The 1789 work articulates an important statement of the foundations of utilitarian philosophy — it also represents a pioneering study of crime and punishment. Bentham's reasoning remains central to contemporary debates in moral and political philosophy, economics, and legal theory.

a This is an outline of a coherence theory of law. Its basic ideas are: reasonable support and weighing of reasons. All the rest is commentary.a (TM) These words at the beginning of the preface of this book perfectly indicate what On Law and Reason is about. It is a theory about the nature of the law which emphasises the role of reason in the law and which refuses to limit the role of reason to the application of deductive logic. (...) In 1989, when the first edition of On Law and Reason appeared, this book was ground breaking for several reasons. It provided a rationalistic theory of the law in the language of analytic philosophy and based on a thorough understanding of the results, including technical ones, of analytic philosophy. That was not an obvious combination at the time of the booka (TM)s first appearance and still is not. The result is an analytical rigor that is usually associated with positivist theories of the law, combined with a philosophical position that is not natural law in a strict sense, but which shares with it the emphasis on the role of reason in determining what the law is. If only for this rare combination, On Law and Reason still deserves careful study. On Law and Reason also foreshadowed and influenced a development in the field of Legal Logic that would take place in the nineties of the 20th century, namely the development of non-monotonic (a defeasiblea (TM)) logics for the analysis of legal reasoning. In the new Introduction to this second edition, this aspect is explored in some more detail. (shrink)

Law, Morality and Society Essays in Honour of H.L.A Hart.

What does it mean to assert or deny the existence of a legal system? How can one determine whether a given law belongs to a certain legal system? What kind of structure do these systems have, that is--what necessary relations obtain between their laws? The examination of these problems in this volume leads to a new approach to traditional jurisprudential question, though the conclusions are based on a critical appraisal, particularly those of Bentham, Austin, Kelsen, and Hart.

In his choice of texts, the Editor has been faced with the difficult task of selecting, from among the author's more than 600 publications, those of the greatest philosophical interest. It is chiefly the topics of value-rela tivism and the logic of norms that have been kept in view. The selection has also been guided by the endeavour to reprint, so far as possible, texts which have not hitherto appeared in English. At times, however, this aim has had to be (...) discarded, in order to include works of key im portance and also the latest expressions of Kelsen's view. In addition to the two topics already mentioned, the Editor has con sidered Kelsen's discussions of the causal principle to be so far worthy of philosophical attention, that some writings on causality and account ability have been included in this collection of philosophical studies.

Explains the concept of legal competence (or power). This book then discusses the analysis and definition of legal concepts in general; the relation between the concept of competence and (in)validity; what it means to exercise competence; different types of competence; and competence norms.

Investigates the resolution of contradictions and ambiguous derogations in a code, by means of the imposition of partial orderings. Although formulated as a study in the logic of norms, it provided the initial ideas for work on the logic of theory (or belief) change, developed by the authors in a series of papers by the authors and Peter Gardenfors beginning in 1985.

Norms conferring public or private powers, i.e., the competence to issue other norms, play a very important rôle in law. But there is no agreement among legal philosophers about the nature of such norms. There are two main groups of theories, those that regard them as a kind of norms of conduct (either commands or permissions) and those that regard them as non-reducible to other types of norms. I try to show that reductionist theories are not quite acceptable; neither the (...) command-variety (Kelsen, Alf Ross inOn Law and Justice), nor the permission-variety (von Wright, Kanger, Lindahl) provide a satisfactory account of competence norms.Among the authors who maintain that competence norms are different from (and hence not reducible to) norms of conduct are Hart, Ross inDirectives and Norms, and Searle. Ross and Searle distinguish between regulative and constitutive rules as two radically different kinds of rules and classify competence norms among constitutive rules. This distinction runs parallel to von Wright's distinction between rules that are prescriptions and determinative rules. While the first regulate actions (by commanding, prohibiting, or permitting them), determinative rules define certain concepts. To view competence norms as (partial) definitions of certain legal concepts (like those of legislator, judge, etc.) seems to open interesting perspectives and to shed light on at least one aspect of these elusive norms.

Traditionally legal theorists, whenever engaged in controversy, have agreed on one point: legal norms are par excellence rules which impose obligations. The author examines this assumption, which from another perspective (that of constitutional law, for instance) appears less obvious. In fact, constitutional rules are commoniy empowering norms, norms which do not create duties but powers. To this objection many theorists would reply that empowering rules are incomplete and that they are to be understood as parts of duty‐creating rules. A different (...) position from this traditional stance is that defended in Kelsen's later writings, according to which the fundamental type of norm is the empowering norm. The author discusses Kelsen's three theories on the “ideal form” or structure of the legal norm, with special attention to the third of these, the empowerment theory. (shrink)
