The Oxford Handbook of Secularism offers a wide-ranging examination of secularism on a global scale, bringing together an international collection of views from prominent experts in a variety of fields. This volume reflects the impressive level of academic attention now given to secularism across the humanities, social sciences, law and public policy, and international relations. Long-reigning theories about the pace of secularization, and ideal church-state relations, are here scrutinized by a new generation of scholars studying secularism with new questions, better data, and fresh perspectives.
