He developed theoretical proposals that have been used in disciplines that are not traditionally related to philosophy, such as law, education, discourse analysis, artificial intelligence, or medical communication. Through his papers and books, Walton redefined the boundaries not only of argumentation theory, but also logic and philosophy. He was a philosopher in the sense that his interest was developing theoretical models that can help explain reality, and more importantly interact with it. For this reason, he proposed methods that have been used for analyzing different types of dialogical interactions, and modeling procedures for regulating them.23468430engPhilosophyIntroduction to the Special Issuejournal article10.22329/il.v42i1.7210Douglas Walton and his Contribution to Argumentation Theoryhttps://www.scopus.com/pages/publications/85126927775https://informallogic.ca/index.php/informal_logic/article/view/7210
