Looking back over the last 40 years of work in the philosophy of religion provides a fascinating vantage point from which to assess the state of the discipline today. I describe central features of American philosophy of religion in 1970 and reconstruct the last 40 years as a progression through four main stages. This analysis offers an overarching framework from which to examine the major contributions and debates of process philosophy of religion during the same period. The major thinkers, topics, (...) positions, and controversies are presented, analyzed, and critiqued. In the concluding section I offer a critical appraisal of the state of the field today based on the results of these historical analyses. (shrink)
