This book considers two interrelated core questions. The first is: how have legal philosophers systematized law, and what types of assumptions have they made in undertaking this task? Second, in what sense is law a system, and how is it maintained as such? In answering the first question the book surveys and analyses the theories of a number of European legal philosophers and in answering the second puts forward its own distinct theory.

This book investigates the relationship between liberal democracies and ontology, that is, philosophical claims about the constitution of agents and the social world. Many philosophers argue that ontology needs to be avoided in political and legal philosophy. In fact, political liberalism, a highly influential paradigm founded by the philosopher John Rawls, makes the avoidance of ontology a core ambition of its ‘political, non-metaphysical’ programme. In contrast to political liberalism, this book argues that attending to ontological disputes is essential to political and legal philosophy. Illuminating, criticising and developing ontological arguments does not only enhance our understanding of justice, but also highlights key features of democratic citizenship. The argument is built up by bringing together three traditions of thought that have so far not been confronted with one another: political liberalism, the work of Michel Foucault, and the psychoanalytic theories of Sigmund Freud and Donald Winnicott. The book also investigates more concrete implications of ontological disputes by drawing on several case studies: a Dutch political-legal debate about greeting rituals; an American conflict about the legalisation of religious freedom; and the struggles for resilience of two American social movement groups.

This book uses the philosophy of Thomas Kuhn to provide a new vision of the development of European comparative law that will challenge and inspire scholars in the field.With the ‘empathic’ use of some ideas from Kuhn’s theories on the history of science – paradigm, paradigm-shift, puzzle-solving research and incommensurability – the book rethinks the modern history of European comparative law from the late 19th century to the modern day. It argues that three major paradigms determine modern comparative law:- historical and comparative jurisprudence, - droit comparé, and - post-World War II comparative law.It concludes that contemporary methodological trends are not signs of a paradigm-shift toward a postmodern and culturalist understanding of comparative law, but that the new approach spreads the idea of methodological plurality.

This book takes an interdisciplinary approach to the relationship between law, time, and new technologies to explain the emergence and transformation of global law, with a special focus on platform economy. It describes the ‘metamorphoses of global law’ on the basis of an experimental understanding of legal theory that looks beyond the systematisation of dogmatic categories, the reproduction of prefabricated theories. It offers a novel and sound theoretical approach to the formation of society within a highly digitalised and platform-oriented world, conjugating the work of several relevant authors, such as Niklas Luhmann, Gunther Teubner, Carl Schmitt, Jürgen Habermas, and Lawrence Lessing, among others.The book answers the myriad questions that the platform economy poses for law, shedding light on the possibility of a hybrid regulation, i.e., the mixture of political-constitutional external regulation and a self-regulation by the digital code, in an attempt to overcome simplistic notions of platform governance. It provides a comprehensive exploratory analysis on the phenomena of digitalisation, platformisation, big data, algorithms, and their relevance to law in global society.

This volume,which offers a bridge between comparative law and legal theory, centers upon debates about European legal integration, and, more generally, about the methodology of comparative law. What should be compared? Statutory rules, case law, legal history, law's political, sociological and economical environment, the ideological background of the lawyers, legal techniques, legal traditions, legal cultures, etc.? This question is at the core of many current debates and is discussed in many of the papers contained in this volume. The contributors all attempt to locate law in its context, and adopt a more theoretical and interdisciplinary approach to making comparisons. In taking an interdisciplinary approach many of the contributors look at our current law from the point of view of one non legal discipline, with an eye on at least some other elements of law's context: notably legal history, legal sociology (especially 'legal culture') and linguistics.They also contribute new ideas to various areas of legal theory including legal epistemology, pluralist or monist conceptions of a 'legal system', legal methodology, judicial reasoning, the theory of legal sources, and the analysis of concepts such as 'equality', 'rights', 'legal principles', 'personal rights' and 'personal identity'.

This book is about legal theory and legal reasoning. In particular,it seeks to examine the relations that obtain between law and a theory of law and legal reasoning and a theory of legal reasoning. Two features of law and legal reasoning are treated as being of particular importance in this regard: law is institutional, and legal reasoning is formal. These two features are so closely connected that it is reasonable to believe that in fact they are simply two ways of looking at the same issue. This becomes clearer as the focus of the book shifts from the institutional nature of law to the consequences of this for legal reasoning, and which is the principal focus of the book. The author received the European Academy of Legal Theory award in 2000 for the doctoral dissertation on which this work was based.

Human interaction and communication are not only regulated by law,but such communication plays an increasing role in the making and legitimation of law, involving various kinds of participants in the communication process. The precise nature of these communications depends on the legal actors involved -- for instance legislators, judges, legal scholars, and the media -- and on the situations where they arise - for instance at the national and supra-national level and within or between State law and non-State law. The author argues that our conception of legal system, of democracy, of the legitimation of law and of the respective role of judges, legislators and legal scholars should be based on a pluralist and communicative approach, rather than on a monolithic and hierarchical one. This book analyses the main problems of jurisprudence from such a communicative perspective

Legal argumentation consists in the interpretation of texts. Therefore, it has a natural connection to the philosophy of language. Central issues of this connection, however, lack a clear answer. For instance, how much freedom do judges have in applying the law? How are the literal and the purposive approaches related to one another? How can we distinguish between applying the law and making the law? This book provides answers by means of a complex and detailed theory of literal meaning. A new legal method is introduced, namely the further development of the law. It is so far unknown in Anglo-American jurisprudence, but it is shown that this new method helps in solving some of the most crucial puzzles in jurisprudence. At its centre the book addresses legal indeterminism and refutes linguistic-philosophical reasons for indeterminacy. It spells out the normative character of interpretation as emphasized by Raz and, with the help of Robert Brandom's normative pragmatics, it is shown that the relativism of interpretation from a normative perspective does not at all justify scepticism.On the contrary, it supports the claim that legal argumentation can be objective, and maintains that statements on the meaning of a statute can be right or wrong, and take on inter-subjective validity accordingly. This book breaks new ground in transferring Brandom's philosophy to legal theoretical problems and presents an original and exciting analysis of the semantic argument in legal argumentation. It was the recipient of the European Award for Legal Theory in 2002. 'This book represents, on the one hand, a reception of Robert Brandom's important theory including applications of this theory in the field of legal philosophy and, on the other, an exploration of the limits of an appeal in legal interpretation to the text. The enquiry thereby impinges upon the central juridico-philosophical themes of meaning, objectivity, and normativity. The author's work counts as a significant contribution to analytical jurisprudence and is deserving of a wide readership.' Robert Alexy, Professor for Public Law and Legal Philosophy, Kiel. 'Klatt focuses on a very profound theory of concept formation and uses this theory in a creative way to solve classical problems of legal argumentation.'Aleksander Peczenik

Critical human interests are affected on a daily basis by appeal to past decisions deemed to be ‘legally valid’. They include statutes, deportation orders, judgments, mortgage contracts, patents and wills. Through the technique of validity, lawyerly reasoning settles morally pressing matters in a way that largely bypasses moral argument. Legal philosophy has paid considerable attention to validity criteria, but it has neglected to explore validity’s point: whether, and if so how, the pervasive technique of validity can contribute to a legal system’s ability to realise justice and human rights.This book shows that validity can help a political community to foster justice precisely because validity does not primarily turn on moral considerations. Validity serves to both allocate, and limit, a distinct kind of power, a power that is key to forging valuable forms of enterprise and commitment in pursuit of individual and collective self-direction. By entrusting the capacity to decide to those who, in justice, ought to bear it, validity can enable persons and institutions to rally the resources and opportunities that only large-scale behavioural convergence can afford, thereby weaving a fabric of just relationships within the systemic framework of law.

La question du temps ne cesse de se poser au droit et à la société, entre amnistie et imprescriptibilité, mesures d’urgence et développement durable, droits acquis et lois rétroactives, respect du précédent et revirements de jurisprudence. Comment donc équilibrer stabilité et changement ? Comment fonder la mémoire collective tout en s’affranchissant d’un passé traumatique ou obsolète ? Comment garantir le futur par des règles, tout en les révisant quand il le faut ? Le temps, c’est de l’argent, dit l’adage populaire. Partant, au contraire, de l’idée que le temps c’est du sens et qu’il s’institue plus qu’il ne se gagne, ce livre pose les conditions d’un temps public, véritable enjeu de démocratie.

Qu’est-ce que les mythes et les grands archétypes de la littérature universelle nous enseignent sur l’origine et le destin du droit ? La donation de la loi du Sinaï, l’invention de la justice chez Eschyle, la révolte de conscience d’Antigone, la souveraineté de l’individu pour Robinson Crusoé, les paradoxes de la liberté chez Faust, la déchéance de la loi avec Kafka : telles sont les étapes majeures d’un parcours narratif aux sources d’un imaginaire juridique trop souvent méconnu. Entre le « tout est possible » du récit et le « tu ne dois pas » de la loi, l’institution du social ne cesse de s’inventer des formes inédites. Au rebours d’une vision formaliste ou moraliste du juridique, ce livre poursuit une grande ambition : replonger le droit dans la fiction littéraire pour lui permettre de renouer avec ses racines.

Et si, au commencement, et peut-être à la fin, étaient le crime, le mensonge, l’imposture ? Sade passe vingt-huit ans de sa vie à l’ombre de la loi. Il n’aura de cesse, en des milliers de pages d’une écriture sans merci, d’en démontrer l’absurdité et l’injustice. Mais n’est-il pas lui-même l’esclave d’une autre loi, bien plus cruelle que celle de la cité ? Plus qu’une apologie du crime, toute son œuvre n’est-elle pas une certaine manière de restaurer ce qu’elle nie par ailleurs ? Et que vise, au fond, cette contestation radicale de l’ordre social, qui défie les régimes politiques, sape les lois de la cité, corrompt les lois de la nature, détourne celles de la logique et subvertit celles de l’écriture ? Une enquête fascinante sur l’existence tumultueuse et l’écriture sulfureuse du divin marquis ; la première étude globale sur le rapport de Sade au mal, à la loi, à la perversion avec, en guise de conclusion, un dialogue imaginaire entre Sade et Portalis, l’auteur du Code civil.

Shakespeare was fascinated by law, which permeated Elizabethan everyday life. The general impression one derives from the analysis of many plays by Shakespeare is that of a legal situation in transformation and of a dynamically changing relation between law and society, law and the jurisdiction of Renaissance times. Shakespeare provides the kind of literary supplement that can better illustrate the legal texts of the sixteenth and early seventeenth centuries. There was a strong popular participation in the system of justice, and late sixteenth-century playwrights often made use of forensic models of narrative. Uncertainty about legal issues represented a rich potential for causing strong reactions in the public, especially feelings concerning the resistance to tyranny. The volume aims at highlighting some of the many legal perspectives and debates emplotted in Shakespearean plays, also taking into consideration the many texts that have been produced during the latest years on law and literature in the Renaissance.
