“This book is a compelling case that there is a deep connection between argumentation and ethics. In particular, we need to reflect on how and why we argue with each other. This requires that we think through not only the issues on which we disagree but the roles we take when we work it all out. Stevens’s insights here are invaluable, and they reflect the profound stakes for how we reason together.”Scott Aikin, Vanderbilt University, USA"The Ethics of Argumentation makes a closing argument against single, ideal argumentation theories. It synthesizes scholarship in philosophy and communication to clear ground that has been broken here and there in explaining the impossibility, impracticality, and immorality of a single ideal. It urges attention to context in a way that guards against easy dismissals as relativism, and will be an intellectual force for argumentation scholars to reckon with."Beth Innocenti, University of Kansas, USA
