The holocaust never happened. The planet isn't warming. Vaccines harm children. The Earth is flat. Denialism comes in many forms, often dressed in the garb of scholarship. It's certainly insidious, but what if, as Kahn-Harris asks, it actually cloaks much darker, unspeakable, desires? If denialists could speak from the heart, what would we hear? Kahn-Harris sets out to expose what lies at the heart of denialism. The conclusions he reaches are shocking. In a world of 'fake news', are the denialists about to secure victory? Dr Keith Kahn-Harris is a writer and sociologist. The author of four books, his interests range from the British Jewish community to extreme metal music scenes.
