To loop or not to loop

A *slight* inconsistency here, quoted without comment:

(1)

Surely you don't consider the feedback function
to be part of the control system, do you?

(2)

The fact is that you guys just have a wrong conception of how control
works -- its a circle, not a chain.

Do you see the contradiction? We keep trying to tell you that we NEED the
circle, and you keep trying to tie us up with the chain. You deny us in
your challenges the opportunity to use the necessary circle, and then
tell us our analysis won't work because we think we don't need the
circle.

Good for you! I would have brought this up, too, but I already know where
things would probably head: toward bringing in a conception of the
relative "importance" of some components of the loops relative to other
components. I've been down that path too many times before with Bill and
Rick. When I have told them that assigning such "importances" is not a part
of PCT modeling, but an ethically (pragmatically) based adjunct to PCT
models, the conversation breaks down. I'll sit this round out... except
that my problem with Rick's concept of the "myth" of environmental
causation does relate to the relative importance stuff.

Lots of luck,

Greg
