Advances in the Psychology of Religion [PDF ebook] 

This collection of previously unpublished papers, written by well known researchers in the psychology of religion, is unique in its broad coverage and in its comparison between quite different and strictly theoretical perspectives. The subjects range from theoretical analyses of social science perspectives on religion and its methods, to reports of experimental, correlational or descriptive studies of religious experience and attitudes. The emphasis throughout is on the directions in which this work might move in the future.
