The Enigma of Reason

If reason is what makes us human, then why do we humans often behave so irrationally? Taking us from desert ants to Aristotle, cognitive psychologists Hugo Mercier and Dan Sperber explore how our 'flawed superpower' of reason works, how it doesn't, and how it evolved to help us develop as social beings. 'Original and provocative ... likely to have a big impact on our understanding of ourselves' Steven Pinker 'Brilliant, elegant and compelling ... turns reason's weaknesses into strengths, arguing that its supposed flaws are actually design features that work remarkably well ... A timely and necessary book' Julian Baggini, Financial Times 'Hugo Mercier and Dan Sperber have solved one of the most important and longstanding puzzles in psychology' Jonathan Haidt 'Reason is more likely to confirm things that we want to be true, or which we already believe. So why does it exist? This book provides the answer' Alex Dean, Prospect

"Brilliant...Timely and necessary." -- Financial Times "Especially timely as we struggle to make sense of how it is that individuals and communities persist in holding beliefs that have been thoroughly discredited." --Darren Frey, Science If reason is what makes us human, why do we behave so irrationally? And if it is so useful, why didn't it evolve in other animals? This groundbreaking account of the evolution of reason by two renowned cognitive scientists seeks to solve this double enigma. Reason, they argue, helps us justify our beliefs, convince others, and evaluate arguments. It makes it easier to cooperate and communicate and to live together in groups. Provocative, entertaining, and undeniably relevant, The Enigma of Reason will make many reasonable people rethink their beliefs. "Reasonable-seeming people are often totally irrational. Rarely has this insight seemed more relevant...Still, an essential puzzle remains: How did we come to be this way?...Cognitive scientists Hugo Mercier and Dan Sperber argue that] reason developed not to enable us to solve abstract, logical problems... but] to resolve the problems posed by living in collaborative groups." --Elizabeth Kolbert, New Yorker "Turns reason's weaknesses into strengths, arguing that its supposed flaws are actually design features that work remarkably well." -- Financial Times "The best thing I have read about human reasoning. It is extremely well written, interesting, and very enjoyable to read." --Gilbert Harman, Princeton University
