Does the law contain implicit exceptions to its own rules? If so, what consequence does that have for understanding the relationship between law and morality? This collection gathers leading legal philosophers to analyse the logical structure of legal norms, advancing the understanding of the general philosophy of law.

Have you ever read a legal opinion and come across an odd term like the fallacy of denying the antecedent, the fallacy of the undistributed middle, or the fallacy of the illicit process and wondered how you missed that in law school? You’re not alone: every day, lawyers make arguments that fatally trespass the rules of formal logic—without realizing it—because traditional legal education often overlooks imparting the practical wisdom of ancient philosophy as it teaches students how to “think like a lawyer.” In his book, The Force of Logic: Using Formal Logic as a Tool in the Craft of Legal Argument, lawyer and law professor Stephen M. Rice guides you to develop your powers of legal reasoning in a new way, through effective tips and tactics that will forever change the way you argue your cases. Rice contends that formal logic provides tools that help lawyers distinguish good arguments from bad ones and, moreover, that they are simple to learn and use. When you know how to recognize logical fallacies, you will not only strengthen your own arguments, but you will also be able to punch holes in your opponent’s—and that can make the difference between winning and losing. In this book, Rice builds on the theoretical foundation of formal logic by demonstrating logical fallacies through the use of anecdotes, examples, graphical illustrations, and exercises for you to try that are derived from common case documents. It is a hands-on primer that presents a practical approach for understanding and mastering the place of formal logic in the art of legal reasoning. Whether you are a lawyer, a judge, a scholar, or a student, The Force of Logic will inspire you to love legal argument, and appreciate its beauty and complexity in a brand new way.

Within limits, the law allows for exceptions. Or so we tend to think. In fact, the line between rules and exceptions is harder to draw than it seems. How are we to determine what counts as an exception and what as part of the relevant rule? The distinction has important practical implications. But legal theorists have found the notion of an exception surprisingly difficult to explain. This is the longstanding jurisprudential problem that this book seeks to solve.

"Logic and law have a long history in common, but the influence has been mostly one-sided, except perhaps in the 5th and 6th centuries B.C., where disputes at the market place or in tribunals in Greece seem to have stimulated a lot of reflection among sophistic philosophers on such topics as language and truth. Most of the time it was logic that influenced legal thinking, but in the last 50 years logicians began to be interested in normative concepts and hence in law"--

This book focuses on the problems of rules, rule-following and normativity as discussed within the areas of analytic philosophy, linguistics, logic and legal theory. Divided into four parts, the volume covers topics in general analytic philosophy, analytic legal theory, legal interpretation and argumentation, logic as well as AI& Law area of research. It discusses, inter alia, “Kripkenstein’s” sceptical argument against rule-following and normativity of meaning, the role of neuroscience in explaining the phenomenon of normativity, conventionalism in philosophy of law, normativity of rules of interpretation, some formal approaches towards rules and normativity as well as the problem of defeasibility of rules. The aim of the book is to provide an interdisciplinary approach to an inquiry into the questions concerning rules, rule-following and normativity.

This handbook addresses legal reasoning and argumentation from a logical, philosophical and legal perspective. The main forms of legal reasoning and argumentation are covered in an exhaustive and critical fashion, and are analysed in connection with more general types (and problems) of reasoning. Accordingly, the subject matter of the handbook divides in three parts. The first one introduces and discusses the basic concepts of practical reasoning. The second one discusses the general structures and procedures of reasoning and argumentation that are relevant to legal discourse. The third one looks at their instantiations and developments of these aspects of argumentation as they are put to work in the law, in different areas and applications of legal reasoning.

This book presents the current state of the art regarding the application of logical tools to the problems of theory and practice of lawmaking. It shows how contemporary logic may be useful in the analysis of legislation, legislative drafting and legal reasoning concerning different contexts of law making. Elaborations of the process of law making have variously emphasised its political, social or economic aspects. Yet despite strong interest in logical analyses of law, questions remains about the role of logical tools in law making. This volume attempts to bridge that gap, or at least to narrow it, drawing together some important research problems—and some possible solutions—as seen through the work of leading contemporary academics. The volume encompasses 20 chapters written by authors from 16 countries and it presents diversified views on the understanding of logic (from strict mathematical approaches to the informal, argumentative ones) and differentiated choices concerning the aspects of law making taken into account. The book presents a broad set of perspectives, insights and results into the emerging field of research devoted to the logical analysis of the area of creation of law. How does logic inform lawmaking? Are legal systems consistent and complete? How can legal rules be represented by means of formal calculi and visualization techniques? Does the structure of statutes or of legal systems resemble the structure of deductive systems? What are the logical relations between the basic concepts of jurisprudence that constitute the system of law? How are theories of legal interpretation relevant to the process of legislation? How might the statutory text be analysed by means of contemporary computer programs? These and other questions, ranging from the theoretical to the immediately practical, are addressed in this definitive collection.

The concept of convention has been used in different fields and from different perspectives to account for important social phenomena, and the legal sphere is no exception. Rather, reflection on whether the legal phenomenon is based on a convention and, if so, what kind of convention is involved, has become a recurring issue in contemporary legal theory. In this book, some of the foremost specialists in the field make significant contributions to this debate. In the first part, the concept of convention is analysed. The second part reflects on whether the rule of recognition postulated by Hart can be understood as a convention and discusses its potential and limitations in order to explain the institutional and normative character of law. Lastly, the third part critically examines the relations between conventionalism and legal interpretation. Given the content and quality of the contributions, the book is of interest to those wanting to understand the current state of the art in legal conventionalism as well as those wanting to deepen their knowledge about these questions.

Autonomy is the central idea of modern practical philosophy. Understood as self-legislation, autonomy seems to require that the validity of norms depends on recognition, namely, that their addressees, being autonomous agents, recognise these norms to be valid. But how can one be bound by norms whose validity depends on their being recognised as valid by their addressees? The questions of how autonomous morality and, on this basis, the authoritative character of law can be understood, present persistent puzzles that have been widely discussed, but still await a satisfactory solution. This book presents an analysis of the idea of autonomy as self-legislation and its consequences for law and morality. It links the idea of autonomy with the idea of the balancing of normative arguments, develops a notion of normative arguments as distinct from normative judgements and statements and explains claims to correctness and objectivity that are found in normative discourse. Thus, a 'logic of autonomy' emerges, and it is pervasive in normative reasoning. It connects theses regarding the logic of norms, the structure of balancing, human and fundamental rights, legal validity, legal interpretation, and the relations among legal systems, offering a theory of central elements of normative argumentation, a theory that is undergirded by the mutual relations that exist between and among its parts as well as through the relations that it bears to other theories. Moreover, it offers an alternative to Kantian notions of autonomy and provides solutions to problems that other theories have failed to master.

Since its inception in 1968, software engineering has undergone numerous changes. In the early years, software development was organized using the waterfall model, where the focus of requirements engineering was on a frozen requirements document, which formed the basis of the subsequent design and implementation process. Since then, a lot has changed: software has to be developed faster, in larger and distributed teams, for pervasive as well as large-scale applications, with more flexibility, and with ongoing maintenance and quick release cycles. What do these ongoing developments and changes imply for the future of requirements engineering and software design? Now is the time to rethink the role of requirements and design for software intensive systems in transportation, life sciences, banking, e-government and other areas. Past assumptions need to be questioned, research and education need to be rethought. This book is based on the Design Requirements Workshop, held June 3-6, 2007, in Cleveland, OH, USA, where leading researchers met to assess the current state of affairs and define new directions. The papers included were carefully reviewed and selected to give an overview of the current state of the art as well as an outlook on probable future challenges and priorities. After a general introduction to the workshop and the related NSF-funded project, the contributions are organized in topical sections on fundamental concepts of design; evolution and the fluidity of design; quality and value-based requirements; requirements intertwining; and adapting requirements practices in different domains.
