Book excerpt: Is religion all in our heads? Whether you believe that to be true or whether you believe that religion has a corresponding external reality (i.e., God), religion at least begins with our heads, namely the cognitive architecture that predisposes human beings to belief in the sacred supernatural. Cognitive Psychology of Religion explores how research in neuroscience, perception, cognition, child development, social cognition, and cognitive anthropology provides insight into the development of the cognitive faculties of belief that facilitate the transmission of religion. Eames has organized the text into seven chapters that follow a clear and straightforward progression from the different theories of the origin of religion into an exploration on how our minds perceive the environment, form truths, spread beliefs, and take part in various rituals and experiences. Cognitive Psychology of Religion is a concise introduction to the cognitive science of religion and serves as an excellent primary or supplemental text for traditional psychology of religion courses.
