Book excerpt: Argumentation between Doctors and Patients discusses the use of argumentation in clinical settings. Starting from the pragma-dialectical theory of argumentation, it aims at providing an understanding of argumentative discourse in the context of doctor-patient interaction. It explains when and how interactions between doctors and patients can be reconstructed as argumentative, what it means for doctors and patients to reasonably resolve a difference of opinion, what it implies to strive simultaneously for reasonableness and effectiveness in clinical discourse, and when such efforts derail into fallaciousness. Argumentation between Doctors and Patients is of interest to all those who seek to improve their understanding of argumentation in a medical context – whether they are students, scholars of argumentation, or medical practitioners. Frans H. van Eemeren, Bart Garssen and Nanon Labrie are prominent argumentation theorists. In writing Argumentation between Doctors and Patients, they have benefited from the advice of an Advisory Board consisting of both medical practitioners and argumentation scholars.
