Dear Bruno, you made my day.
your explanation which I asked for (> >I mean a short, concise plain
language identification.<<) is such that I even hesitate to
try to follow it.
I may post my formulation (of words) when I feel it good enough
for a list-scrutiny. (On consciousness see some words below).
Does you Mmmmhhhh mean your opposing opinion
(vs a Hhhhmmmm)?
Thanks for the trouble to write, I will try to extract of it whatever
echoes some understanding in my little mind.

PS. The e-mail battle against 'consciousness' was based upon the Tucson
conferences where thousands of scientists from dozens of countries could not
agree in defining it. My opinion was: it is a historical noumenon for some
mental idiom - from ages when the then epistemic level of the cognitive
inventory did not allow an intelligent formulation amd nowadays every author
includes an identification that fits his theory. It is still going on. I
volunteered a definition in total generalization (not sure if I still
totally agree):
"Acknowledgement of and response to information" not restricted
to humans, rather generalized to 'everything' (this was before my
participation in the 'everything' list) as a "pan-sensitivity". The
"response" may be activity, or just storage, unrestricted. Information I
coined as 'difference' accepted.
References? it was in many dozens of list-e-mails on I guess 8 diverse lists
over a decade. I my have most of them in the mess on my *hard* disk. (Hard
to find on it). - JM
