MP: I think a point to note is that, in so far as consciousness
is *about* something or other, the something or other is viewed,
perceived, conceived, constructed, made 'knowable', whatever,
*from a point of view*. This point of view, which is where I
'am' in the relevant context, may be just implicit in most
experiences but is definitely explicit at other times. I think
this reflects our general predisposition to naive realism which
is the product of Darwinian evolution; in many if not most of
the situations in which our early ancestors found themselves it
was not particularly useful to be aware of the process of
construction of the experience, in fact the energy and mind
space necessary to do so would have a very high opportunity
cost, life threatening in fact. To put it another way:
self-awareness is a philosophical necessity but a biological
luxury.

MP: I agree that mental reflection IS a form of higher level
causality. I think though that it is NOT possible to totally
reduce something to something else yet still retain the original
reality in its completeness. But 'reduction', vaccinated with
sufficient doses of 'ceteris paribus', is still enormously
powerful. It is a central tool of scientific method. The way I
see it, what we are calling reduction is in fact *synthesis* of
a representational system which by definition embodies
abstractions of what are considered to be the relevant essential
features, usually requiring some mathematical format to obtain
the maximum leverage.

My acronym for what goes on is "UMSITW" [pronounced
'um-see-two'] which means Updating Model of Self In The World. I
am not impressed by assertions that consciousness is sometimes
not ABOUT anything in particular. I think that the kind of
experiences being referred to, such as a 'no-mind' state of
meditation, are what it is like to be the high gain system when,
after much practice, the brain has been trained to virtually
cease evoking representations.
