Explaining Religion: Notes Toward a Research Agenda

I begin by arguing that our model of religion is often based on Christianity. A Christian model of religion is going to look for gods and creeds, churches, priests, prayer, collective worship, moral codes, each of which is absent in some of the things we might want to call religions. And it may well ignore dietary and sumptuary rules or cult for ancestors, which are important in some of them. Religion is a paradigm of what Wittgenstein taught us to call a “family-resemblance” concept: each religion, like each member of a family, is like every other, in some respect, but there are few, if any, characteristics they all share. So the first thing we need to do in trying to decide what it is we’re explaining is disaggregate the elements that come together in Christianity; if we find that they usually come together that will be one of the things that we need to explain. What then are the questions worth focusing on? I think that, from an evolutionary point of view, it will be two families of issues. First will be the social and the cognitive features of religions that make their explanation challenging. A second family of issues worth exploring, once we have identified these components, is how they fit together. Why, for example does belief in invisible beings go with rituals dealing with disaster? Why does agreement in creeds go with creating powerful social groups that last across the generations? When one finds broad patterns across many societies there are usually two natural types of explanation that spring to mind. One is that the pattern reflects shared solutions to common problems, independently discovered: evolutionary homology, as it were. The other is diffusion from common sources: in a word, copying. I suspect that much of what is share in the organization of religions globally today is the result of diffusion. But, of course, why some patterns diffuse successfully and others don’t is itself something that needs explaining.
