Liberalism and Catholicism are two of the most important forces shaping the contemporary political culture of the United States. This book explores what is at stake as they encounter each other in new contexts today and what a fresh conversation between them promises for the future of American public life. It is based on the conviction that both traditions continue to have much to learn from each other and that both would contribute more constructively to the resolution of the problems facing the nation if they were to do so. It is thus an invitation to the dialogue that could produce such mutual learning, and is a collaborative effort that brings together the work of scholars from a variety of disciplines. Though the book gives particular attention to the United States, it has relevance to debates about the future of liberalism and Catholicism in many other parts of the world.
