Book excerpt: While orthodox religion by its very nature is conservative, philosophy at its best is inherently radical. It challenges authority, tradition, and the whole idea of "dogma." For this reason, philosophy of religion can be explosively controversial. It is bound to disturb those who peddle incontrovertible truth and fascinate those who seek spiritual truth and are willing to follow the argument wherever it leads. This volume is designed for such seekers. It brings together an international team of leading philosophers of religion to explore and debate radical new ideas about religion, God, and ultimate reality. Four related questions are addressed: How might religion make progress? Is life after death a real possibility? Must a perfect God be motivated by our well-being? What alternatives are there to traditional theism and materialist atheism? The book begins with a vision for the field of philosophy of religion and ends with a capstone chapter that touches on all of the topics debated in the other chapters. The addition of chapter overviews, annotated suggestions for further reading, and annotated guides to three additional controversies make it an ideal textbook in addition to being an important source for scholars and seekers of all kinds.
