In this thoroughly revised edition, James Cox provides an easily accessible introduction to the phenomenology of religion, which he contends continues as a foundational method for the academic study of religion in the twenty-first century. After dealing with the problematic issue of defining religion, he describes the historical background to phenomenology by tracing its roots to developments in philosophy and the social sciences in the early twentieth century. The phenomenological method is then outlined as a step-by-step process, which includes a survey of the important classifications of religious behavior. The author concludes with a discussion of the place of the phenomenology of religion in the current academic climate and argues that it can be aligned with the growing scholarly interest in the cognitive science of religion.
