"When like-minded people argue, all they do is provide each other with new reasons supporting already held beliefs."
Anthropologist Dan Sperber has reshaped how we understand human reason—not as a tool for truth seeking, but as an adaptation for persuasion. Sperber contends that what passes for rationality is in fact motivated cognition, selected over thousands of years of evolution for its power to win over others.
Sperber is the author of several books, including The Enigma of Reason. His conclusions challenge long-held and deeply entrenched Enlightenment assumptions about the mind, rationality, and culture.
"Original and provocative...likely to have a big impact on our understanding of ourselves" — Steven Pinker
