I've just finished reading Wade Nicholas' "The Faith Instinct" and he repeatedly enforces how almost every aspect of religious practice is a form of social glue. That basically religion exists the way it does because it brings people together, allowing them to cooperate and thus thrive. But I'm not sure I'm convinced it's enough to say "rituals bring people together" such as soldiers marching or people throwing their hands up in praise. Yes, I agree %100, but is it enough to say that the reason for ritual is to bring people together? It doesn't explain why ritual has this effect, so I'm not sure the explanation really tells us very much about rituals and other religious behaviours that foster social cohesion. Yes? No?
