OK, fair enough.

While I have some understanding of what "ontologically basic mental things" might be (and I am not convinced that "supernatural" is routinely used to mean that), I do not have the vaguest beginnings of a clue what the nuanced definition you are asserting it actually serves as a shorthand for might be, so it's conceivable that I would agree that "supernatural" means it, if I ever did find out what it was.

(I've made a couple of attempts to read the post you link to, but I keep wandering off before I get to the end. IMHO it takes way too long to get to any point worth making.)
