The role played by the humanities in reconciling American diversity - a diversity of both ideas and peoples - is not always appreciated. This volume of essays, commissioned by the American Academy of Arts and Sciences, examines that role in the half century after World War II, when exceptional prosperity and population growth, coupled with America’s expanded political interaction with the world abroad, presented American higher education with unprecedented challenges and opportunities. The humanities proved to be the site for important efforts to incorporate groups and doctrines that had once been excluded from the American cultural conversation.
