The notion that the Supernatural itself ‘exists’ is unsupported – equally unsupported no matter what the Supernatural metaphysics may be: gods, ghosts, fairies, wizards, …. But let’s go with the fantasy.
The question of the interaction between the Supernatural and the Natural raises its head occasionally, and it has been doing the rounds again, and specifically the question of whether the Supernatural is beyond the reach of science. So, supposing for now that there is a Supernatural, what can we know about it?
If the supernatural (S) is distinct from the natural (N), and they do not overlap at all, then what are all the religious claims based on? By this definition of non-interaction Natural human religious entities (theists) cannot experience the Supernatural; and since there are no interactions from S to N we don’t get any miracles to reveal the Supernatural either.
The only way the Natural human religious entities could experience the Supernatural is if there is some interaction between S and N.
So, one interaction might be that the human Natural entities have some Supernatural component that interacts with (witnesses) the Supernatural (e.g. the soul).
Another interaction is one whereby the Supernatural entities (e.g. God) have the capacity to act on the natural world. This is presumed to be the case, since He is supposed to have created the Natural in the first place.
But all interactions we know of in the Natural world are two-way. Cause and effect are mutually connected. So, for the soul to witness Supernatural experiences and transmit them to the conscious mind it must alter the conscious mind. It is the conscious mind of the theist that is making the claim of having an experience.
Both types of interaction are open to investigation by science.
Theists having religious experiences, being ‘in-touch’ with the divine, must be able to be tested. And the results of those tests must rule out (to some reasonable degree) any alternative natural cause for those experiences. All known religious experiences can be explained in terms of known psychological effects that are, at the very least, as feasible as a Supernatural explanation. Given how many alternative Supernatural or otherwise mystical explanations are offered by a multitude of cranks and variations on the religious you’d think the religious, wanting to be certain they are right, would be very concerned by these competing claims – but that’s where faith is required: belief’s cocoon of denial.
Theists claiming Supernatural effects on the Natural also clearly have some explaining to do. All modern claims are testable, and many have been tested and found wanting: faith healing, intercessionary prayer. Nothing. And any historical claims to miracles are sufficiently suspect by virtue of the period of ignorance in which they were made. Any theist who gives credibility to the resurrection must give equal credibility to fairies, imps, goblins, demi-gods, dog-head people, sea monsters (the least incredible), vampires, … Theists have no more grounds for believing in miracles than they do in any other crazy story. But, then again, faith (in one’s own beliefs) comes to the rescue of the reality deniers: no number of suspect mystical entities is sufficient to cause one to suspect one’s own.
So, either S and N interact, and those interactions are testable. Or they don’t, and all theism is just made up crap by Natural entities that have no access to the Supernatural in either direction. I mean to say, if the Supernatural is inaccessible to science, then it’s damned well inaccessible to a few fruit cakes who like to recite chants to their Supernatural Superheroes. So, theists, take your pick. Heads I win, Tails you lose.
Just to throw a spanner into the works, have a closer look at the Venn diagrams above. What’s all that empty space around the Supernatural and the Natural? Should the diagram be more like this?
Well, why should it? If theists can lay claim to the Supernatural without evidence, then I think I’ll go for the Hypernatural (H). You know, home of Hypernatural Thingymabob, that all encompassing thing that created all Supernatural creators of universes, the Thing that created God and gave Him the power to create the Natural.
How far does this stuff go on? Does the Hypernatural interact with the Natural, or just the Supernatural? Is there a Superhypernatural?
Is this getting silly? It already got silly, a few thousand years ago. And as we become more rational and sceptical, and are able to see the Emperor’s clothes for what they are, the whole religious show becomes an obvious invention of imaginative minds.
It’s one thing to hypothesise about the metaphysics of the origins of the universe, or maybe to make guesses about what is required to form an intelligent entity, and whether some such thing caused specific universes to come and go. But that’s all it is, guess work.
Far easier to let everything lie under one roof. It’s Natural all the way. Even the stuff that seems mysterious now will either one day be explained by Natural means, or will remain mysterious – but only in the sense of remaining unknown. Whatever the origins of our universe and any other, when or if they become known to us, they will be investigated, theorised about, and will take their place in our expanding field of Natural knowledge.
The strong nuclear force is something we discovered, or invented, or modelled, however you want to put it. It is now used to explain the interaction between particles in the nucleus of atoms. It was not once Supernatural and then suddenly Natural. Rather, it was once an unknown Natural phenomenon and is now a known Natural phenomenon.
