Public deliberation and group discussion can strengthen the foundations of civil society, even when the groups engaged in debate share a history of animosity. Scholars have begun to study the dialogue sustaining these conversations, especially its power to unite and divide groups and individuals. The twenty-four essays in this collection analyze public exchanges and the nature of sustained dialogue within the context of race relations, social justice, ethnic conflicts, public-safety issues, public management, community design, and family therapy. They particularly focus on college campuses and the networks of organizations and actors that have found success there. Open discussion may seem like an idealistic if not foolhardy gesture in such milieus, yet in fact the practice proves crucial to establishing and reinforcing civic harmony.
