Cognitive Science of Religion (CSR) is still a rather young discipline. Depending on what one deems to be the first paper or book in the field, the discipline is now almost forty or almost thirty years old. Philosophical and theological discussion on CSR started in the late 2000s. From its onset, the main focus has been the (potential) epistemic consequences of CSR, and this focus is dominant even today. Some of those involved in the debate discussed the relevance of CSR for further issues in philosophy of religion, and other have examined how CSR weighs in on various theological questions. Finally, a small number of philosophers offered criticisms or support for various CSR-theories. In this chapter, we give an overview of the debates so far and provide an outline of the book.
