A global overview of evidentiary reasoning with contributions from leading authorities from different legal traditions and four continents.

This book addresses theoretical problems concerning legal evidence. The concept of evidence is expected to fulfill a number of distinct roles in science and philosophy, but also in legal theory and law, some of which are complementary, while others are conflicting. In their profession, lawyers have to deal with evidence and proof. Yet the legal concept of evidence is constantly changing, and the debate concerning the distinction between a legal concept of evidence, the ordinary concept of evidence and the concept of evidence in science is far from being settled. What is more, the problem of evidence is central to both epistemology and the philosophy of science, and by extension to our academic thinking on law. In short, legal theorists’ interest in evidence may include such diverse objects as a bloody knife, sensory data, linguistic entities or psychologically recognized beliefs. The book surveys selected theoretical roles that the concept of evidence plays and explores their relations and interconnections. The content is divided into three parts, investigating: (1) evidence in epistemology and the philosophy of science, which focuses on evidence methodologies and the problem of proof in legal scholarship; (2) evidence in legal theory and legal philosophy, where particular attention is paid to the interplay between evidence, legal reasoning and the binding force of such reasoning; and (3) evidence in law, where theoretical problems pertaining to witnesses, expert opinions, explanations of the accused, statistical evidence and neuroscientific evidence are examined.

In this book a theory of reasoning with evidence in the context of criminal cases is developed. The main subject of this study is not the law of evidence but rather the rational process of proof, which involves constructing, testing and justifying scenarios about what happened using evidence and commonsense knowledge. A central theme in the book is the analysis of ones reasoning, so that complex patterns are made more explicit and clear. This analysis uses stories about what happened and arguments to anchor these stories in evidence. Thus the argumentative and the narrative approaches from the research in legal philosophy and legal psychology are combined. Because the book describes its subjects in both an informal and a formal style, it is relevant for scholars in legal philosophy, AI, logic and argumentation theory. The book can also appeal to practitioners in the investigative and legal professions, who are interested in the ways in which they can and should reason with evidence.

Providing an accessible introduction to the application of multi-criteria analysis in law, this book illustrates how simple additive weighing, a well known method in decision theory, can be used in problem structuring, analysis and decision support for overall assessments and balancing of interests in the context of law.

A leading expert in informal logic, Douglas Walton turns his attention in this new book to how reasoning operates in trials and other legal contexts, with special emphasis on the law of evidence. The new model he develops, drawing on methods of argumentation theory that are gaining wide acceptance in computing fields like artificial intelligence, can be used to identify, analyze, and evaluate specific types of legal argument. In contrast with approaches that rely on deductive and inductive logic and rule out many common types of argument as fallacious, Walton&’s aim is to provide a more expansive view of what can be considered &"reasonable&" in legal argument when it is construed as a dynamic, rule-governed, and goal-directed conversation. This dialogical model gives new meaning to the key notions of relevance and probative weight, with the latter analyzed in terms of pragmatic criteria for what constitutes plausible evidence rather than truth.

What makes an argument in a law case good or bad? Can legal decisions be justified by purely rational argument or are they ultimately determined by more subjective influences? These questions are central to the study of jurisprudence, and are thoroughly and critically examined in Legal Reasoning and Legal Theory, now with a new and up-to-date foreword. Its clarity of explanation and argument make this classic legal text readily accessible to lawyers, philosophers, and any general reader interested in legal processes, human reasoning, or practical logic.
