Religious diversity exists whenever seemingly sincere, knowledgeable individuals hold incompatible beliefs on the same religious issue. Diversity of this sort is pervasive, existing not only across basic theistic systems but also within these theistic systems themselves. This book explores the breadth and significance of such conflict. Examining the beliefs of various theistic systems, particularly within Christianity, Judaism, Hinduism and Buddhism, Basinger discusses seemingly incompatible claims about many religious issues, including the nature of God and the salvation of humankind. He considers particularly the work of Hick, Gellman, Plantinga, Schellenberg, Alston, Wainwright, and Quinn, applying their perspectives on "exclusivism" and "pluralism" as they become relevant to the issues in question. Basinger's survey of the relevant literature, proposed solutions, and fresh insights are intended to offer a contribution not only for philosophers of religion and philosophical theologians but for anyone interested in the increasingly significant question of what a religious believer can or cannot justifiably say about their religious perspective.
