Christopher W. Tindale, Director & Research Fellow





Dr. Tindale received his PhD from the University of Waterloo. He worked for almost 20 years at Trent University in Ontario where he held a number of academic and administrative positions, including Chair of the department of Ancient History and Classics. He was also President of the boards of directors of Hospice Peterborough and the Peterborough AIDS Resource Network. In 2006 he moved 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 lectures at universities around the world, including (in 2014) in North Carolina, Montreal, Amsterdam, Medellin, Bogotá, Shanghai, Beijing, Chengdu, and Guangzhou. His books include Acts of Argument (1999), Rhetorical Argumentation (2004), Fallacies and Argument Appraisal (2007), Reason’s Dark Champions (2010) and The Philosophy of Argument and Audience Reception (2015). His books have been translated into a number of languages, including Spanish, German, and Serbian.


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: ‘Rhetoric and Informal Logic’, and ‘Plato’s Reasons’.
