“Religion” is not, in fact, some simple disposition that could possibly be either innate or learned. It is a highly complex phenomenon both psychologically and culturally, and there are major differences between the forms of religion found in primitive societies and the world religions with which we are familiar, as I have described in detail elsewhere (Hallpike 1977: 254-74; 2008a: 266-87; 2008b: 288-388; 2016: 62-88). But studying all these ethnographic facts is time-consuming and boring, and it is much more fun to assume that we all know what we mean by “religion”—something like “faith in spiritual beings”—and get on with constructing imaginative explanations about how it must have been adaptive for early man.”
