Abstract
This chapter examines how the cognitive science of religion (CSR) relates to naturalism, as both a methodological and a metaphysical principle. CSR is heir to a rich tradition of natural histories of religion that provide integrated causal accounts of religion, based on anthropological, historical, and psychological observations. Natural histories of religion traditionally had a strong antitheistic agenda. This in part explains why CSR is still regarded as a project that has mainly negative implications for the rationality of religious beliefs. The question of whether CSR challenges religious beliefs nevertheless remains a subject of enduring debate. To approach this question, I examine how naturalness is developed as a concept in CSR, exploring McCauley's claim that religion is natural. I conclude that the naturalness of religion does not challenge the epistemic standing of religious beliefs. Notably, this is a result of CSR's self‐imposed methodological constraints, in particular its attempts to reduce religious phenomena to nonreligious cognitive dispositions.
