Related to Monday's post but spun off for length reasons: my crazy theory about where religion comes from.

The near-universal existence of religion across cultures is surprising. Many people have speculated on what makes tribes around the world so fixated on believing in gods and propitiating them and so on. More recently people like Dawkins and Dennett have added their own contributions about parasitic memes and hyperactive agent-detection.

But I think a lot of these explanations are too focused on a modern idea of religion. I find ancient religion much more enlightening. I'm no historian, but from the little I know ancient religion seems to bleed seamlessly into every other aspect of the ancient way of life. For example, the Roman religion was a combination of mythology, larger-than-life history, patriotism, holidays, customs, superstitions, rules about the government, beliefs about virtue, and attempts to read the future off the livers of pigs. And aside from the pig livers, this seems entirely typical.
