Douglas N. Walton

Douglas Neil Walton (born 2 June 1942, died 3 January 2020) was a prominent Canadian academic and author, celebrated for his significant contributions to the fields of argumentation, logical fallacies, and informal logic. His academic career saw him associated with institutions such as the University of Windsor, where he held the Assumption Chair of Argumentation Studies and later served as a Distinguished Research Fellow at the Centre for Research in Reasoning, Argumentation, and Rhetoric. Walton's work is characterized by a practical methodology aimed at identifying, analyzing, and evaluating arguments across various domains, including law, science, and everyday discourse. This approach, which he termed "logical argumentation," emphasizes a dialogue structure, commitment-based analysis, and the study of defeasible arguments and argumentation schemes. His research has found practical applications in legal argument preparation and the development of artificial intelligence. Walton's prolific output includes numerous books and papers, solidifying his legacy as a key figure in contemporary argumentation theory.
