Dr. Keith Kahn-Harris, a British sociologist and commentator, discusses his new book Denial: The Unspeakable Truth. It attempts to analyze the emergence and growing prevalence of denialism - a quasi-nihilist reflex that subsumed healthy skepticism and fact-based debate. This season of the Tel Aviv Review is made possible by The Van Leer Jerusalem Institute, which promotes humanistic, democratic, and liberal values in the social discourse in Israel. Tel Aviv Review is also supported by the Public Discourse Grant from the Israel Institute, which is dedicated to strengthening the field of Israel Studies in order to promote knowledge and enhance understanding of modern Israel.
