Re: models - branch fromf GM discussion



John M.
Your rewording is OK too. However, I think it is will be confusing to
add the qualifier "in the reductionist sciences" because modeling in
terms of relationships and their organization is also
"non-reductionistic" in the strict sense of physical "reductionism",
which is what most people think of when using the term. "Reductionism"
that is, the "ism" does historically refer to reduction to physically
measurable quantities. The Rosennean model, if used as a picture of some
aspect of nature, does introduce non-reductionistic elements in this
sense, and hence a kind of  biological uncertainty which is not
reducible. Yet in a broader sense, it is itself a reduction to
relational concepts. So, as I've stressed before (and will again I'm
sure), it is much more a matter of what we are reducing to, than
reduction itself, which arguably all thinking requires.

Also, a much more minor quibble with the rewording, and my original
wording, is that the goal of science isn't so much to understand models
or completeness, as I think about it, as to understand nature, so I
suppose I would prefer to state it that way - "best available concept of
nature." We can take it as given that the way we understand nature is
through models.

Hello, John K. and Judith,
Thanks for John's concurring ideas in the post - except for one little
correction I want to point out: Instead of the concluding

Why not turn it around, like (a very scanty re-wording):

"For the present, however, speaking of the relational model is
such a major step toward a more complete view of nature in the reductionist
sciences that for present working purposes, this addition gives us our best
and most complete available concept of a "model"."

Please, Judith, don't feel defensive, I do not accuse RR with reductionism.
In spite of  your last reply to me, MY paraphrasing of RR is not 'giving
words in his mouth' ("he never said..."). And from all I so far experienced,
he WAS explaining his ideas as a professor, in a "teaching way",-- to make
others understand and accept the new views he developed.  I am not.

I am all for the successfulness of reductionist science-technology, the
'mechanistic' models we formed brought us down from the tree and out from
the cave. I exercised it for ½ century myself. THINKING is different, with
(in) new vistas, for better (new) understanding.  MR is a good bridge in
between (I wish I knew what it is).
I formulated lately the relational aspects as network-extensions
http://pages.prodigy.net/jamikes/Influence.htm - changing only the format
(wording) of views.
It all depends how much we restrict the boundaries in modeling.
(How much "realtion" fits in).

I think we can talk about "Rosennean models" knowing and keeping in mind,
how far we have to go to be away from the mechanistically cut limited models
(this is what my "but close" referred to in my post to Jack - thanks, Jack,
for you consenting reply to it).

Cheers

Hi John M.
You raise a topic that I have and will come back to many times. The idea
of a "Rosennean model" -- is there such a thing?

Here's how I look at it.

RR's statement that there isn't a largest model means there can by no
complete model that can capture all aspects of a complex system. It does
not say there can be no useful models.  Mechanistic models are one
example of both statements. I accept this argument fully, based on the
explanation he provided in convincing detail and with considerable
emphasis and repetition.

I also belive there is a kind of model that is not mechanistic in its
foundation, which describes certain aspects of systems that are
different than what mechanistic models can describe. These look a lot
like Rosen modeling relationships themselves, and they describe the
natural relationship between functional specifications (models) and
their realization in material systems. Such models can indeed tell us
something important about nature, particularly biology, because they
represent an aspect of nature that is excluded by mechanistic models.
Their incompleteness, in part, is in excluding the mechanistic model. We
gain understanding of certain relational aspects, but need to go to
mechanistic models for representing non-relational aspects. Hence in my
work, for examepe, it is necessary to consider both kinds of models,
recognizing that neither is a complete descriptions, and the most likely
even the two kinds of models taken together will not provide a complete
description. For the present, however, adding the relational model is
such a major step toward a more complete view of nature that for present
working purposes, this addition gives us our best available concept of
completeness.

Jack,
what kind of "model" do you want to call "Rosennean"?
A "maximum model" it can't be, a 'limited model" is stuff
for reductionist un-wholly (excuse the pun) views.
I don't call a "Rosennean model" an oximoron, but close.
Maybe, if you craft according to the MR, you may end up
with a "model" that refers to more than a reductionistic
cut-off, I mean: a topical view within set boundaries, but
aren't we playing with the word "model" just to please(!)
the general audience (= average hostile scientists)?

I may have misunderstood the problem and assign your
"Rosennean" to imply "R. complexity" - impredicative
and 'Turing non-computable'? IMO RR wrote his books with such length and
circumlocution to make his ideas compatible to those who are on a


different


track. I am more pragmatic and don't care for understanding by those in


the


opposite camp.

Then again, I am neither a biologist nor a mathematician.

My response would be a simple question:

What steps must I take to craft a Rosennean model using their data and
anything else I might need, such that I gain the ability to study their
results with a different model than the one(s) they presumably applied
to get those results?
