Is there such a thing as a just war? Is terrorism ever morally acceptable? And can ancient art change the current view of history? This program investigates these and other questions with political philosopher Michael Walzer, who examines the origins of modern terrorism; classicist Glen Bowersock, whose study of ancient mosaics is helping him deepen his understanding of great conquests from antiquity; and Oleg Grabar, a historian of Islamic art, who discusses the religious and political volatility of the Dome of the Rock. In addition, Kirk Varnedoe, formerly of New York’s Museum of Modern Art, talks about Jackson Pollock and what exactly makes modern art so modern. (57 minutes)
