Rationally Speaking #141 - Dan Sperber on "The Argumentative Theory of reason"

The traditional story about reason is that it evolved to help humans see the world more clearly and (thereby) make better decisions. But on that view, some mysteries remain: why is the human brain so biased? Why are we so much better at defending our pre-existing views than at evaluating new ideas objectively?

In this episode of Rationally Speaking, Julia talks with guest Dan Sperber, professor of cognitive and social sciences, who is famous for advancing an alternate view of reason: that it evolved to help us argue with our fellow humans and convince them that we're right.

Dan Sperber is a social and cognitive scientist. His most influential work has been in the fields of cognitive anthropology and linguistic pragmatics. Sperber currently holds the positions of Directeur de Recherche émérite at the Centre National de la Recherche Scientifique and Director of the International Cognition and Culture Institute.
