A focus on reasons for action and practical reason is the perspective chosen by many contemporary legal philosophers for the analysis of some central questions of their discipline. This book offers a critical evaluation of that approach, by carefully examining the empirical, logical and normative problems hidden behind the concepts of `reason for action' and `practical reasoning'. Unlike most other works in this field, it is a meta-theoretical study which analyses and compares how differen...

This book is an updated and revised edition of Fundamentals of Legal Argumentation published in 1999. It discusses new developments that have taken place in the past 15 years in research of legal argumentation, legal justification and legal interpretation, as well as the implications of these new developments for the theory of legal argumentation. Almost every chapter has been revised and updated, and the chapters include discussions of recent studies, major additions on topical issues, ne...

Legal statements are, according to the authors, the most basic elements of the law. Nevertheless they must be considered not only as the pieces of a puzzle, but also as the components of a dynamic and highly complex reality: the law of contemporary society. The book presents an analysis of the different types of legal statements (mandatory rules, principles, power-conferring rules, definitions, permissions, values and the rule of recognition) from a threeefold perspective, that is, conside...

Questions about the relationship between autonomy and authority are raised in nearly every area of moral philosophy. Although the most ob vious of these is political philosophy (especially the philosophy of law), the issues surrounding this relationship are by no means confined to this area. Indeed, as we shall see as this work progresses, the issues raised are central to moral psychology, religion, professional ethics, medical ethics, and the nature of moral systems generally. Although th...

This is the first ever collected volume on John Austin, whose role in the founding of analytical jurisprudence is unquestionable. After 150 years, time has come to assess his legacy. The book fills a void in existing literature, by letting top scholars with diverse outlooks flesh out and discuss Austin’s legacy today. A nuanced, vibrant, and richly diverse picture of both his legal and ethical theories emerges, making a case for a renewal of interest in his work. The book applies multiple ...

This book provides a new, linguistic approach to Argumentation Theory. Its main goal is to integrate the logical, dialectical and rhetorical dimensions of argumentation in a model providing a unitary treatment of its justificatory and persuasive powers. This model takes as its basis Speech Acts Theory in order to characterize argumentation as a second-order speech act complex. The result is a systematic and comprehensive theory of the interpretation, analysis and evaluation of arguments. T...

As the dedication ofthis book suggests, the genesis ofthis book arises from my association with Cha'im Perelman. Because I was one of the few Americans to comment on his TraUe de l' argumentation: la nouvelle rhetorique, before it was translated into English, I was invited to a conference celebrating the translation ofthat monumental work into English that was held in August 1970 in Santa Barbara, Califomia at the Center for the Study ofDemocratic Institutions, which was then under the dir...

Informatics and the Foundations of Legal Reasoning represents a close collaboration between a wide range of disciplines and countries. Fourteen papers, together with a long analytical introduction by the editors, were selected from the contributions of legal theorists, computer scientists, philosophers and logicians who were members of an International Working Group supported by the European Commission. The Group was mandated to work towards determining how far the law is amenable...

Rule-applying legal arguments are traditionally treated as a kind of syllogism. Such a treatment overlooks the fact that legal principles and rules are not statements which describe the world, but rather means by which humans impose structure on the world. Legal rules create legal consequences, they do not describe them. This has consequences for the logic of rule- and principle-applying arguments, the most important of which may be that such arguments are defeasible. This book offers an e...

This volume explores the relation between legal reasoning and logic from both a historical and a systematic perspective. The topics addressed include, among others, conditional legal acts, disjunctions in legal acts, presumptions and conjectures, conflicts of values, Jørgensen´s Dilemma, the Rhetor´s Dilemma, the theory of legal fictions and the categorization of contracts. The unifying problematic of these contributions concerns the conditional structures and, more particularly, the relat...

The judiciary is in the early stages of a transformation in which AI (Artificial Intelligence) technology will help to make the judicial process faster, cheaper, and more predictable without compromising the integrity of judges' discretionary reasoning. Judicial decision-making is an area of daunting complexity, where highly sophisticated legal expertise merges with cognitive and emotional competence. How can AI contribute to a process that encompasses such a wide range of knowledge, judgm...
