 Argumentation theory has a tradition of taking fallacies as an operational concept for identifying problems with arguments. The types of deficiency identified as fallacies emerge from disparate points in the history of philosophy, and, as Charles Hamblin (1970) first recognized, the fallacies approach to argument evaluation tends to lack consensus regarding what constitutes a fallacy. Further, many theorists find that “fallacy” fails as both an analytic category (Massey 1995) and a pedagogical tool (Hitchcock 1995), and yet the scholarly controversy has not put a stop to the regular use of fallacies for evaluating arguments and for teaching reasoning. Feminists share the ambivalence of other philosophers regarding fallacies, adding their own criticisms and developments, but a specific controversy emerges in regard to the adversarial nature of fallacies.
