I personnaly deny the concept of "measure of conscious experiment". I deny
the fact that consciousness is an *objective* property of matter, just
because you can not define a physical property, measurable by an external
apparatus, whose measure could determine the degree of consciousness (or if
you can, let me know).

Much of the discussion about consciouness is plagued by this fact, because
we include it in formalisms that have not been deviced to handle it.  The
only consciousness we know is our own one, by means that are different from
those we use to interact with the outer world. We think that the other
human beings are conscious because of the similarity of their behavior with
ours, but it does not define what is consciousness. If one succeeds in
building a computer with a human-like behaviour (which is quite possible in
my sense), deciding if it is actually conscious or not is purely a matter
of convenience, not an intrinsic property. In other words, I think the
proposition "Another than me is conscious" is really unprovable.
