(via) Reality vs. Perception of Reality
In answer to Bruno’s recent comments on the old post:
* Thanks for helping me sort out my ‘Nagels’! I had them mixed up in EndNote.
* Young? 49 years young. Getting young and seemingly knowing less and less
every day. :-) This I seem to have to conclude is progress of a sort.
I’ve caught up with the ‘subjective reality’ thread and am finding the usual
linguistic blurs, wondering how to resolve them. Part of the process is to
ensure we are all talking about the same things. It seems there is room for
some work in this regard. In going through the posts it seems to me there is an
overlap in the word ‘subjective’ in a very specific way.
a) Firstly there is ‘subjective’ in the sense of experiential content (the
‘now’ of our experiential fields vision, haptic, emotion etc)). This is
implemented in brain material in some way. What the brain feels.
b) Secondly there is knowledge derived from that experience. This is devoid of
experiential qualities and is reported as a belief. “Mr X had a headache on
that day” is the example used here. What the brain does. This is a belief whose
truth may or may not be supported by empirical evidence. This is formed by a
separate brain mechanism.
There seems to be a tendency for these two to get mixed up. You can see
evidence in the thread: the interpretive mismatch actually caused discussion to
occur. Both of these constructs a) and b) can be characterised as ‘virtual’. In
case (a) the brain makes the outside natural world have an appearance ‘as if it
were like that’. In case b) the belief is a ‘truth’ about the natural world and
the holder of the belief acts (behaves) ‘as if’ it were true.
Both are subjective in that they are properties of a subject (a brain) and the
result of that subject’s view of the natural world (=not the brain) as an
object. This leads is into the next potential confusion c) subject in contrast
to d) object. This too has been in the possibly confused mixture and was well
recognised by Lee.
This may be a confusion of word subject/object vs subjective/objective. Don’t
Then there is the final confusion (? Not sure) e) that ‘measurement’ in the
quantum mechanical sense of a so-called ‘observer moment’ and its relationship
to a), b) c) and d). For I do not think they are the same thing. The quantum
mechanical ‘observer moments’ happen continually at all places, scales and
times where the natural processes taking place demand that resolution of
position/velocity some other pair be resolved to a certain state. This is the
massive collection of falling trees in the unobserved forest. They still fall
in the sense that Schrödinger’s cat ‘fall’. This form of ‘observation’ may
actually occur in a brain and be relevant to a), b), c) , d) but it does not
necessarily _define_ a), b), c) d). I believe this to be an accidental cultural
mis-interpretation that seems to continue unchallenged. Or am I seeing
something that is not there?
There seems to sometimes be a tacit assumption that QM observation and
observation by a cognitive agent inclusive of a phenomenal consciousness are
literally the same thing or necessarily related or that QM is necessarily
causal in phenomenal consciousness. A corollary of this is that if you do a QM
depiction of the universe unfolding that somehow phenomenality has been
depicted. This is not necessarily the case. To me they seem to be two
completely separate aspects of the natural world that may or may not be
connected and the confusion that they are seems to be in place here.
So here we are all thinking we are talking about the same thing whereas there
seem to be at least 5 separable aspects to the discussion (a,b,c,d,e above).
They appear very distinct to me, anyway, and in order to have any meaningful
discussion it would seem that these 5 things be very clearly defined. Or have
I just done that?
