Dr. Tindale

Dr. Tindale received his PhD from the University of Waterloo. He worked for almost 20 years at Trent University in Ontario, moving in 2006 to the University of Windsor to become a fellow of the Centre of Research in Reasoning, Argumentation, and Rhetoric and a professor in the department of Philosophy. He also lectures in the Argumentation Studies PhD and supervises students in that program. He is the co-editor (with J. Anthony Blair) of the journal Informal Logic; and the co-editor (with Leo Groarke) of the Windsor Studies in Argumentation book series. His books include Acts of Argument (1999), Rhetorical Argumentation (2004), Fallacies and Argument Appraisal (2007), Reason’s Dark Champions (2010), The Philosophy of Argument and Audience Reception (2015), and The Anthropology of Argument (2021). His work has been translated into a number of languages, and a selection of his essays appeared in Spanish in 2017: Retórica y teoría de la argumentación contemporáneas: ensayos escogidos de Christopher Tindale.

Research Interests:

Dr. Tindale’s research concentrates on argumentation and rhetoric, including the development of argumentation in ancient Greek philosophy. He is currently engaged on two projects: ‘Argumentation and Extremism’, and ‘Plato’s Reasons’.
