Bøker av Douglas Walton

Placing the rise in teaching of applied logical reasoning and critical thinking within an historical context, this text stresses that many universities are now using this skill at an introductory level. It seeks to provide the reading required to understand the development of this subject.

This monograph poses a series of key problems of evidential reasoning and argumentation. It provides a hands-on survey explaining to the reader how to use current argumentation methods and concepts that are increasingly being implemented in more precise ways for the application of software tools in computational argumentation systems.

Bridging the gap between applied ethics and ethical theory, Ethical Argumentation draws on recent research in argumentation theory to develop a more realistic model of how ethical justification actually works.

This text identifies 25 argumentation schemes for presumptive reasoning and marches a set of critical questions to each. These two elements are then used to evaluate a given argument in a particular case in relation to a context of dialogue in which the argument occurred.

Use of argumentation methods applied to legal reasoning is a relatively new field of study. The problems studied include not only these of argument evaluation and argument invention, but also analysis of specific kinds of evidence commonly used in law, like witness testimony, circumstantial evidence, forensic evidence and character evidence.

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 proposes a new and practical approach to argument analysis based on his theory that different standards for argument must apply in the case of different types of dialogue.
