Sword,
The model of reality may be the theoretical position, the philosophy behind it is what is seen in practice. It's the same with your claim
Just now though, all "we" know of that can be reliably accessed and investigated is the natural.
Nope with sprinkles on. The only “theoretical” bit is the axioms on which naturalism rests – that we exist at all, that the world wasn’t created last Thursday etc. Beyond that though, it’s just practical inter-subjective experience. You and I will each hit the deck shortly afterwards if we jump out of the same window, so we agree on that that model of reality.
The implementation isn't consistent with this:
The "falsification" of that statement would be finding something other than the natural that could be reliably accessed and investigated.
Of course it is. If you can do that, then I’ll change my model of reality.
It’s simple enough isn’t it?
As the reliably accessed and investigated assumes natural causes and explanations. This is what makes the whole approach circular.
It does no such thing, and you still don’t understand what “circular reasoning” means. All it assumes is some basic axioms, but if ever you could come up with a means reliably to access and investigate what you call the “non-natural” then I’d be perfectly open to changing my model of reality. That in other words would be the test that falsified my current model.
One example: Floo on the Tomb of Jesus being opened thread:
Quote from: Hope
Sadly, for both Floo and yourself, Walter, there are a number of examples where people have been pronounced dead on the evidence of modern medical equipment, but returned to life same time later. This alone suggests that the 'As it isn't credible ...' argument is open to debate.
Quote from: Floo
They obviously weren't really dead!
No idea why you’re quoting Floo at me. If you want to have that discussion though, I suggest you take it up with her on the relevant thread.
So when Vlad talks about the philosophy, one aspect of this is a commitment to natural-only causes and explanations.
It probably would be if anyone actually had such a “commitment”, yes. Has anyone said they have?
As this is neither proven or falsifiable, any implementation of it has to be circular.
That’s still not what “circular”, means but if you’re trying to say it would be an unverifiable assertion then yes it would. As I understand it that’s what people called “physicalists” do, but not materialists or naturalists. As you’ve referenced Vlad, amusingly he insisted on using Wiki for his authority on naturalism and materialism meaning the absolutist position of physicalism, only to find that they actually mean pretty much the opposite of that. I quoted the relevant bits
verbatim a while back if you can be bothered to look for them.
