This edited volume represents the best of the scholarship presented at the 18th National Communication Association/American Forensic Association Conference on Argumentation. This biennial conference brings together a lively group of argumentation scholars from a range of disciplinary approaches and a variety of countries. Disturbing Argument contains selected works that speak both to the disturbing prevalence of violence in the contemporary world and to the potential of argument itself, to disturb the very relations of power that enable that violence. Scholars' essays analyze a range of argument forms, including body and visual argument, interpersonal and group argument, argument in electoral politics, public argument, argument in social protest, scientific and technical argument, and argument and debate pedagogy. Contributors study argument using a range of methodological approaches, from social scientifically informed studies of interpersonal, group, and political argument to humanistic examinations of argument theory, political discourse, and social protest, to creatively informed considerations of argument practices that truly disturb the boundaries of what we consider argument.
