Consider This on July 18, 2014 - The Island of Knowledge
This program features a conversation with Marcelo Gleiser, the Appleton Professor of Natural Philosophy and Professor of Physics and Astronomy at Dartmouth College. He is the author of four books, most recently The Island of Knowledge: The Limits of Science and the Search for Meaning. This book addresses such questions as, "Do all questions have answers? How much can we know about the world? Is there such a thing as an ultimate truth?"
