Daniel Dennett is one of the world's most original and provocative thinkers. A philosopher and cognitive scientist, he is known as one of the 'Four Horseman of New Atheism' along with Richard Dawkins, Sam Harris and the late Christopher Hitchens. In 2013 he came to Intelligence Squared to share the insights he has acquired over his 40-year career into the nature of how we think, decide and act. Dennett revealed his favourite thinking tools, or 'intuition pumps', that he and others have developed for addressing life's most fundamental questions. As well as taking a fresh look at familiar moves - Occam's Razor, reductio ad absurdum - he discussed new cognitive solutions designed for the most treacherous subject matter: evolution, meaning, consciousness and free will. — We’d love to hear your feedback and what you think we should talk about next, who we should have on and what our future debates should be.  Send us an email or voice note with your thoughts to podcasts@intelligencesquared.com or Tweet us @intelligence2.  And if you’d like to support our mission to foster honest debate and compelling conversations, as well as ad-free podcasts, exclusive bonus content, early access and much more, become a supporter of Intelligence Squared..
