Consilience: The Unity of Knowledge

How are chemistry, biology, and art all related? Today on Focus, we'll talk to entomologist Edward Wilson, author of Consilience. In his recent book, he discusses links between fields of science, from brain chemistry to the biology of cave paintings. We'll explore these remarkable syntheses today on the show.

Guest: Edward O. Wilson (entomologist; two-time Pulitzer Prize winner; author of Consilience: The Unity of Knowledge)
