This volume explores the contributions to the field of social ethics by David Hollenbach, one of the most prominent voices in the promotion of the common good over the past half-century. Whatever became of the idea of a common good ? Ethicists and theologians lament the decline in public life of the importance of this concept, so central to the character of civil society and so crucial for the flourishing of individuals within it. In our own culture, the promotion of the common good is a valuable corrective to our atomised morality and laissez-faire economics. This volume, on the 30th anniversary of the famous U.S. Bishops’ economics pastoral letter, brings together some of the leading lights in ethics to discuss the role, impact, and importance of public theology across the globe.
