Re: Rosen cf. Kauffman

Tim,
Thank you for sharing your views with me. I am, however, further puzzled
after having read the following paragraphs from your post:
Referring to Kauffman: " ....It has been said by many that we do not
understand the linking of matter, energy, and information. The circle above
points at something we must trouble ourselves to understand, and I suspect
that the triad of energy, matter, and information is insufficient. Rather,
the "missing something" concerns organization. While we have, it seems,
adequate concepts of matter, energy, entropy, and information, we lack a
coherent concept of organization, its emergence, and self-constructing
propagation and self-elaboration."[p.104],
and then referring to Rosen you say:
"Rosen's approach, conversely, is centrally about the role of organization
and the ability to study it divorced from matter, that leads to his
results."
How come could, these two scientists being contemporary and I guess knowing
the work of each other, not think of benefiting from each other and
collaborate, if not when Rosen was alive, but now Kauffman could think of
finding the missing something in the Rosen's work?? With all the knowledge
around why could disciples of Rosen make an attempt to merge the two not
close but perhaps complementary theories? Therefore, can we not do the same
by to applying Rosen's theory into practice in variety of fields which
requires organization as their central concern by making the whole system
(mostly complex) function synergistically? Are they naive questions or even
so can they take put us on a right track? Sorry for all these inquisitions.
Thank you for your patience.
Ayten
