In The Enigma of Reason, Hugo Mercier and Dan Sperber (2017) defend the proposal that reason is a specialized module which produces intuitions about reasons. Reason serves two functions: for individuals to justify their own judgments and actions to themselves and others, and to persuade others. In this review, I briefly summarize the central claims of the book, critically examine Mercier and Sperber’s arguments that reason is not a general faculty underlying our inferential abilities, and explore the pedagogical implications of their work.
