It's enshrined in encylopedias! yes it's a problem We don;t know. It was
#2 in "big questions" in science mag last year.

Then the proposition should be able to say exactly where, why and how. It
can't, it hasn't.

Yes but in order that you be mistaken you have to be aware you have made a
mistake, which means admitting you have missed something. The existence of
an apparently unsolvable problem... isn;t that a case for that kind of
behaviour? (see below to see what science doesn't know it doesn't know
about itself)

You have missed the point again.

a) We demand CONTENTS OF phenomenal consciousness (that which is
perceived) as all scientific evidence.

but

B) we do NOT accept phenomenal consciousness ITSELF, "perceiving" as
scientific evidence of anything.

Evidence (a) is impotent to explain (b). Empirical fact - 2500 of total
failure. So, why not allow ourselves the luxury of exploring candidate
physics of underlying realities that appears to provide phenomenal
consciousness in the way that we have? Indeed more than that...such that
it also makes the universe look like it does when we do science on it
using it = (a)? A very tight constraint. Phenomenality is the evidence
source for 2 sets of descrptions not one - both equalliy empirically
supported.

If we accepted (B) as evidence we'd be doing this already. We don't. We're
missing half the picture.
