to quote from "Life Itself" page 15: "Why the problem is hard""As a first step
in
our assault on the problem What is life? it will be well to get some idea of
what
we are up against. Specifically, we will try to understand what it is about the
problem that has rendered it so refactory to the combined resources of our
contemporary scientific wisdom....................though we will not be able to
come to a true answer to this question until we come to the end.
Let us begin by noting the very form of this question; we are asking
WHY...............What is life? .......is really a why question in
disguise.......why a specific material system is an organism, and not something
else....."
I do this to remind you that Rosen has specific answers to questions NO ONE else
has answered, not "all the answers". Also we discuss here material that
overlaps
with none of the more common scientific approaches. This is a radical departure
and can't be lumped among a pile of alternative classical techniques.

It is a bit of a misrepresentation, but the idea of a commutative map is common
in
set theory. What do you find unclear about it?

You clearly have not read the three chapters in "Anticipatory Systems" which the
sections in "Life Itself" refer to. There he builds up the elements of
correspondence between the symbols in the formal system and the symbols in our
PERCEPTION of the natural system. He does this with the other aspects
too...with
great care and VERY convincingly. What you are forgetting is that our only acess
to
the natural system for manipulations like the modeling relation is after
perception.

This is one of Rosen's main points...please stop misrepresenting him!

Now we get into his definition of complexity. What is the problem?

Rosen says this....he sees relational biology as just one more DISTINCT way of
interacting with a complex system.

and more....why don't you recognize the fact that you are giving his argument as
a
counter argument of your own?

what Rosen does is not traditional cybernetics. You keep misrepresenting to
tear
down the straw man. In the paper he refers you to he develops how he goes
beyond
the cybernetic black box in his relational, category theory argument. Please be
more careful!

if you understand the context this replication is a natural consequence of
metabolism/repair....it is derivable from it and EMERGES from it. I object to
your
use of judgemental statements to deny things you are merely not willing to
study.

the key work is: Some Relational Cell Models: The Metabolism-Repair System."
Chapter 4 of Foundations ofMathematical Biology Vol. 2, 217-253. N.Y. & London,
Academic Press. 1972
(a fairly complete bibliography of his work is at http://views.vcu.edu/complex/)

You totally misunderstand ...how can one use mechanisms in a development
designed
to be non-mechanistic?

you are saying he doesn't answer any question other than the one he asked....why
does that become a problem....find somewhere where he addresses the problem you
are
interested in and critique that...it wasn't bveing addressed here. (again see
references listed in page above)

yes......they are all over the place....

Read Rosen's paper critiquing von Neuman......he shows why von Neuman was
totally
wrong!

your comments seem to be mainly about the 70% you missed. Do not interpret this
as
an attempt to be rude as it is not. It is my frank opinion. You need to do
lots
more work before you understand even why you are having difficulty....it is not
in
Rosen's work...but in your own unfamiliarity with it. Only you can deal with
that.
