The Common Good and Christian Ethics rethinks the ancient tradition of the common good in a way that addresses contemporary social divisions, both urban and global. David Hollenbach draws on social analysis, moral philosophy, and theological ethics to chart new directions in both urban life and global society. He argues that the division between the middle class and the poor in major cities and the challenges of globalisation require a new commitment to the common good and that both believers and secular people must move towards new forms of solidarity.
