The reactions to the psychological strokings are biological
obviously. The ORIGIN of religion has NOTHING to do with biology as you implied in your previous post./quote]
You will agree that religious experiences can be attributed to biology, and that biology is ultimately coded by DNA, yes?
Let me state with finality, the origin of religion has no biological basis. The continuation of religion is indoctrination. Religion is not written in DNA therefore is not inheritable. These institutions were totally dreamed up by folks with political agenda and the wish to control masses and/or the planet.
Indoctrination is also biological. People have a psychological need for acceptance by other people. This need is rooted in our DNA, as we are the descendents of social hominids.
Religion itself may not be written in our DNA, but a whole multitude of factors, due to what makes up a person, lead to a biological basis in religion.
If religion is the cause of biological processes, we should expect to find theistic developments the world over.
We do find this to be the case. At least, I have never heard of an atheistic society existing until the past few hundred years.
(While Buddhist monks can practice the finer arts of Buddhism, most of the poor and uneducated peasants have different practices, such as appeasement of ghosts and demons, and the like)
People are rational and pattern-seeking.
To use our rationality effectively, we must find patterns and causal links. As an early human in a new environment, pattern seeking behavior would be crucial to survival. From knowing which berries taste like burning and what kind of animals leave what kind of tracks, to building fire and making tools.
These behaviors require searching for patterns, discovering the pattern, and then manipulating it to our advantage. This rationality is incredibly powerful, as it allows us to manipulate our environment and predict the outcomes of complicated actions.
Pattern seeking is (or was) an entirely utilitarian endeavour, best suited to technological goals. A false positive while engaging in a technological pursuit will eventually reveal itself. Square wheels don't role well for instance. This can easily be demonstrated. It's far less expensive, in the long run, to mistakingly see a pattern where there isn't one, than be prone to missing patterns.
In fact, finding patterns is so useful, it's more beneficial to always look for patterns rather than ignore possible patterns. Pattern seeking behavior is obvious in humans, and many times we find patterns that don't exist.
When it comes to immaterial pursuits, especially predicting future events, we are far less capable. Reality is too complex, with too many variables, to possibly compute all at once. So we construct models. Though inherently flawed in their simplicity, models allow us to predict events with some degree of accuracy.
By observing past events and patterns and observing future patterns, our minds take which events they percieve as important and construct a model from them.
Religion is simply a model for reality. It takes an incomplete set of variables and looks for a pattern, either seeing a pattern where there isn't one (chaos) or seeing an incomplete pattern. Yet religion holds a certain amount of truth (whatever that is), as it models something that is real: reality.
I imagine early man, looking up at the sky, wondering what the lights twinkling above his head meant. He made up stories, based upon his life, for what the stars meant. In time, man came to see patterns in the behavior of individuals born under certain stars. Astrology makes sense. It's not immediately appearant that stars are burning balls of gas millions of skillions of miles away. And people born during certain months share behaviors with each other. We see patterns that aren't there.
That's what religion is, or at least where it came from. Of course, religions now are complex socio-cultural histories & guides for group behavior. Prior to all that though, we were just looking for a way to explain the world. Our pattern seeking behavior, our rationality, did just that.
