This program presents lectures by Michael Sugrue and Darren Staloff based on their seminar course at Columbia University on Western intellectual history, as well as lectures by Alan Charles Kors and Dennis G. Dalton. The lectures in Part III cover the great British and French Enlightenment periods of the 17th and 18th centuries, a period of widespread religious disbelief, expanded faith in science and of early responses to the industrial revolution. This period marks the intellectual flowering that led to the American Revolution.
