Andy,
I'm not excluding the supernatural, nor am I asserting naturalism. Never have, never will. Naturalism has a burden, yes, but since I'm not asserting it I don't have to defend it. You, on the other hand, do exactly that with the supernatural, but instead of defend it, you continuously burn straw.
You need to watch Chummy here because - along with various other terms he abuses ("scientism", "category error" etc) he plays fast and loose with the word "naturalism" in order to set up the straw man he wants to critique. Most if not all are content to take its standard meaning of, "the natural is all we know of that's reliably accessible and verifiable" with no comment on the supposed "supernatural', the "super-super natural" or any other white noise term for claimed phenomena outside of that.
By re-defining it though as "all there is or can be" yer man gives himself the straw man he needs to respond with a "how do you know that?"
And even if he did eventually find someone who proposed his personal re-definition of "naturalism", he'd
still have all his work ahead of him finally to tell us what he means by "supernatural" and to demonstrate its existence at all.
That's what I mean when I talk about dishonesty - you simply cannot have a conversation with someone who just makes up his own meanings for words in order to attack them.
