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...

Walton has made a successful attempt to write about medical concerns without ever leaving the layperson to flounder in confusion. "Probate Law Journal"
In recent years the question of when to terminate life-extending medical treatments has become a thorny social issue. Douglas Walton has brought together a number of these case studies and analyzed the very difficult issues they raise.
A well-organized, thoughtful, and logical discussion of a difficult ethical issue frequently encountered by clinicians.
This book offers a new theory of begging the question as an informal fallacy, within a pragmatic framework of reasoned dialogue as a normative theory of critical argumentation. The fallacy of begging the question is analyzed as a systematic tactic to evade fulfillment of a legitimate burden of proof by the proponent of an argument. The technique uses a circular structure of argument to block the further progress of dialogue and, in particular, the capability of the respondent to ask legitimate critical questions in reply to the argument. Walton analyzes the concept of burden of proof in...

We are happy to present to the reader the first book of our Applied Logic Series. Walton's book on the fallacies of ambiguity is firmly at the heart of practical reasoning, an important part of applied logic. There is an increasing interest in artifIcial intelligence, philosophy, psychol- ogy, software engineering and linguistics, in the analysis and possible mechanisation of human practical reasoning. Continuing the ancient quest that began with Aristotle, computer scientists, logicians, philosophers and linguists are vigorously seeking to deepen our understanding of human reasoning and...

In Relevance in Argumentation, author Douglas Walton presents a new method for critically evaluating arguments for relevance. This method enables a critic to judge whether a move can be said to be relevant or irrelevant, and is based on case studies of argumentation in which an argument, or part of an argument, has been criticized as irrelevant. Walton's method is based on a new theory of relevance that incorporates techniques of argumentation theory, logic and artificial intelligence. arguments, strategies of attack in argumentation, and fallacies. Walton reviews ordinary cases of...

The traditional equation of the death of a person with irreversible cessation of cardiorespiratory function-the absence of heartbeat, pulse, or respiration-is being replaced by modern medicine with a definition of death in terms of irreversible destruction of function-brain death. In this book, the author thoughtfully and analytically surveys and evaluates the arguments for and against equating the death of a person with brain death. The ethical issues-both theoretical and practical-are explored against a rich and comprehensive background of current medical thought and practice and the most...

Recent concerns with the evaluation of argumentation in informal logic and speech communication center around nondemonstrative arguments that lead to tentative or defeasible conclusions based on a balance of considerations. Such arguments do not appear to have structures of the kind traditionally identified with deductive and inductive reasoning, but are extremely common and are often called "plausible" or "presumptive," meaning that they are only provisionally acceptable even when they are correct. How is one to judge, by some clearly defined standard, whether such arguments are correct or...

Douglas N. Walton considers the question of whether the conventions of informal conversation can be articulated more precisely than they are at present. Specifically, he addresses the problem of the fallacy of ad hominem argumentation as it occurs in natural settings. Can rules be formulated to determine if criticisms of apparent hypocrisy in an argument are defensible or refutable? Walton suggests that they can, and ultimately defends the thesis that ad hominem reasoning is not fallacious per se. He carries his analysis to the core of action--theoretic reasoning--by examining a number of...

Walton offers a comprehensive, flexible model for physician-patient decision making, the first such tool designed to be applied at the level of each particular case. Based on Aristotelian practical reasoning, it develops a method of reasonable dialogue, a question- and-answer process of interaction leading to informed consent on the part of the patient, and to a decision--mutually arrived at--reflecting both high medical standards and the patient's felt needs. After setting forth his model, he applies it to three vital ethical issues: acts of omission, the cessation of treatment, and...
