Ahhh!!! good responses from both Francis and Bruce!!

Francis, Ill look forward to seeing if I can pull some of your papers off
the Internet through Netscape. Unfortunately, our university library here
doesnt carry the International Journal of General Systems... perhaps I can
get the article through inter-library loan...

I think it will be very fruitful to spend more time examining whether Rosen's
ideas on the measurement problem converges with what the physics
community went through earlier this century with quantum measurements.
I know Rosen was critical of the quantum probabilistic state equation as
being just another form of reductionism that had the same pitfalls... I
personally want to understand all of this better.

This does seem to exactly parallel what Rosen said in his most recent paper.

Rosen also seems to say (unless I'm misinterpreting him) that meaning can
emerge relationally between components. But I have a suspicion that Rosens
components involve some kind of infinite structure that can not be computed.
This seems to me to be a very important issue and I want to hear all of your
ideas.

Rosen apparently starts before human perception...before understanding of
meaning.

I think Rosen would say that we take a thermometer and take the temperature...
but at this level (to be totally objective), the thermometer just outputs
meaningless symbols (which we cant understand if we are to strictly
obey objectivity). To get more information about what those symbols mean,
we would have to construct another device, and so on and so on...
We see an unpleasant incipient infinite regress in the process of information.

>This would be an indicator of faulty method, a sort of software problem.

Agreed!!!! This is the main point Rosen is driving at. He is critiquing
total objectivity. You are absolutely right that we can understand what the
symbols mean on the thermometer. We dont need an infinite number of
other devices...

I agree with this. We see what objectively would be some meaningless
symbol and then we process that information, attaching meaning that is
relative to our context, creating knowledge.

I agree. I think, though, that Rosen was asking the question From a purely
objective point of view: " how do we process information, attaching meaning?"

Agreed.

I think that Rosen doesn't believe in total objectivity, but he wants to
pose the issue in totally objective terms. When he does that, an infinite
regress forms. You could dismiss this development (of trying to be
totally objective) as an inappropriate method. Ultimately you are probably
right. I think what Rosen is suggesting is that it may be useful, though, to
purely objectively study an object, but that object would have to be an
impredicativity (an infinite regress turned back on itself as I understand it).

Im still in the process of formulating my opinions so any comments are
welcome.
