Book excerpt: This book is the summation of many decades of work by Peter L. Berger, an internationally renowned sociologist of religion. Secularization theory—which saw modernity as leading to a decline of religion—has been empirically falsified. It should be replaced by a nuanced theory of pluralism. In this new book, Berger outlines the possible foundations for such a theory, addressing a wide range of issues spanning individual faith, interreligious societies, and the political order. He proposes a conversation around a new paradigm for religion and pluralism in an age of multiple modernities. The book also includes responses from three eminent scholars of religion: Nancy Ammerman, Detlef Pollack, and Fenggang Yang.
