OK, lets try to work through this.

Well, I am afraid I don't, otherwise I would not have brought this
up. You had just posted an e-mail ("An attempt to get back on track
:complexity ala Rosen"), which seemed to basically say that the way
forward was not to argue about Rosen's view (as you express it) but
to jointly study his view more. It implied that criticism was
misplaced due to the fact that our scholarship was "sloppy" (which
seemd to mean that all we needed to do was to study Rosen more.
(please correect me if this is a mis-reading). This is very
frustrating for me, as I find his view brilliant but not perfect and
hence I want to argue about it. The way forward you were suggesting
seemed inimicable to my needs.

There is a difficulty in criticising a holistic position, (and
especially by e-mail. Whenever I object to anything written from you
(which is all I have of your views on this) you seem to say that I
have not taken into account some context, which is part of what you
intend but which I have not seen yet. If I did not criticise exept
where I knew the full context - this would effectively rule out
criticism - hence my first comment above. It is not meant to be
sarcastic but literal (within some presumably common framework in
which we are trying to communicate).

The actual definition suffers from the same criticisms (as I have
enumerated many times, so the fact that I argue here rather than
elsewhere is not of evil intent.

That depends what the "real point" is - to learn more about Rosen's
view or generally seek for truth(s). We will have an inevitable
difference of view here. Rosen's views will probably never be as
important to me as they obviously are for you. You seem not to
accept this in dialogue with me.

Well, not quite. Rosen as a scientist, takes a philosphical
viewpoint of the "reality" of direct interaction with natural systems
that I see as more problematic. Thus he does not emphasise the
difficulties implicit in the assumption of a single observer making
different models (as opposed to many observers making different
models). This is a difference of empahsis between scientist and
philosopher - we see difficulties at different stages.

This is correct, within the limited history of biology (and the like)
trying to work within a reductionist science. I, as you know, am
seeking a broader perspective than this. Hence, my search for a
definition of 'complexity' that matches the common intuitive version
more, but without losing its analytic and philosophical value. Which
is "better" must depend on context. So what I am implicitly arguing
is that Rosen's use of 'complexity' is limited (i.e. will only be
directly useful) in the context of the holist/reductionist debate.

Everybody in this discussion is focussing on their own needs -
hopefully these are general enough in the pursuit of some form of
truth so we can have a worthwhile discussion - one that may be
helpful beyond the _immediate_ politics of each.

Now I think I am going to have to disagree with you here. Rosen does
not make it clear that he considers this as the derivation of a
subjective idea of complexity, if it is, it is only implicit. He
states that objective knowledge is possible - a direct relation
through measurement to the real world happens (effectively).

1, You must remember that I have what is, from my (and other's)
point of view, a wider concern than just the holistic/reductionist
battle ground in science (and society). Most people will, after all,
agree that there are complex machines, if you go out in the street
and ask them (to take a very trivial example of a differnt context).

2. The fact that complexity is defined involving the number of
disctinct systems that ... and that in language (whic is all we have
got) there are distinct practical (you call them technical)
difficulties to this *are* problems with this approach (i.e. they
may further retrict the contexts in which this definition/approach
is useful).

3. You seem very frustrated with what you see as your inablility to
sufficiently articulate Rosen(et al.)'s ideas. You seem to artibute
a large part of other's disagreement with your expression of these
ideas to this (and the fact it is holistic). Thus you are
particularly sensitive to what you see as (willful) misunderstanding
and nit-picking and react by re-stressing what you see as the
inappropriateness of the form of the criticism and urge people to
study Rosen(et al.) more. I ask you to consider the possibility
that some of us DO understand enough of Rosen's intention but just
disagree with some aspects of his thoughts. This is my situation. I
find that while I greatly appreciate his direction and substantially
agree with a lot of what he has to say, I think some aspects of his
though are lacking. If you always react to this in what *seems* a
very patronising way (something on the lines of "you have just
misunderstood me/Rosen again") this will not help for a constructive
dialogue.

Maybe so. Can you please do me the honour of assuming (unless there
is direct evidence to the contary) that I am not ignorant - otherwise
it is difficult to have any debate (A - "I disagree", B- "therefore
you need to study more"). Even if it was due to ignorance, this
approach does not help (me).

I can certainly learn to imporve my style. I know that I am not
censored, but when people communicate they do mutually define the
rules of that communication. If one person seems to unilaterally
apply their own rules of interpretation on the exchange then this
will effectively prevent communication to that person. Thus to a
large extent we DO need permission to communicate with others. I
want (more of) an agreement of the framework of communication with
you (the media militates against this).

1. Yes you can sterilize in many ways.

2. The source of your views is you. I want to talk about YOUR views
(however based on Rosen's).

Surely we do only have our own views - even if based on others, even
it is a view of what someome else's view is. I can't have a dialogue
with Rosen on this list - if I wnt his views I'll read him (as I do).
I want to work out ideas with you and others.

I would greatly appreciate this. This seems linked to what I said
above. Maybe we do need to establish more of a methodology of
dialogue here.

It is an expression of my frustration. I wrote what *seems* to be.
I explicitly hoped it was not the case. I am more concerned with the
dynamics of the communication.

No but you can prevent me communicating with you by your choice of
the framework in which you consider my communications.

OK, you sense of responsibilty you feel when expressing your views
gives the impression that you do think he is CORRECT.

OK, it can be very frustrating for others trying to communicate with
you if you always use that measuring stick as a framework.

OK, can you (this is a request- please feel free to decline) speak
only for your views, Rosen can well stand up for himself in his
writings. Also can you suggest a way of approaching debates
(including criticism) about holistic issues that you would find
acceptable/helpful/...

Thank you.
