If reason is so useful and reliable, why didn’t it evolve in other animals and why do humans produce so much thoroughly reasoned nonsense? Hugo Mercier and Dan Sperber argue that reason is not geared to solitary use. It evolved to help justify our beliefs to others, evaluate their arguments, and better exploit our uniquely rich social environment.

The Enigma of Reason

Dan Mercier

Reason, we are told, is what makes us human, the source of our knowledge and wisdom. If reason is so useful, why didn't it also evolve in other animals? If reason is that reliable, why do we produce so much thoroughly reasoned nonsense? In their ground-breaking account of the evolution and workings of reason, Hugo Mercier and Dan Sperber set out to solve this double enigma. Reason, they argue with a compelling mix of real-life and experimental evidence, is not geared to solitary use, to arriving at better beliefs and decisions on our own. What reason does, rather, is help us justify our beliefs and actions to others, convince them through argumentation, and evaluate the justifications and arguments that others address to us.The Enigma of Reason will spark debate among psychologists and philosophers, and make many reasonable people rethink their own thinking.
