Naturalism, Theism and the Cognitive Study of Religion [PDF ebook] 
Religion Explained?

This book provides a critical philosophical analysis of the claim that contemporary cognitive approaches to religion undermine theistic beliefs. Recent scientific work into the evolution and cognition of religion has been driven by and interpreted in terms of a certain kind of philosophical and methodological naturalism. The book argues that such naturalism is not necessary for the cognitive study of religion and develops an alternative philosophical and methodological framework. This alternative framework opens the cognitive study of religion to theological and philosophical considerations and clarifies its relationship to other approaches to religious phenomena. This unique contribution to discussions regarding the philosophical and theological implications of the cognitive study of religion summarizes the so far fragmentary discussion, exposes its underlying assumptions, and develops a novel framework for further discussion.
