Anyone care to wish me a happy birthday? (:->
Rick Marken (980624.2200) --
It would be nice if all PCT advocates could agree about (almost)
everything related to PCT. But I don't think there is any magic
way to get this agreement. Have you noticed any significant
disagreement between Bill and myself over coercion (or any other
PCT topic) by the way? Bill and I tend to agree because we both
understand (from working with models and using these models to
mimic behavior) how the PCT model works and how it applies to
behavior.
This is only partly true. Sometimes Bill and you agree because you are
talking about the same fundamentals, such as how the standard PCT control
system behaves under various disturbance waveforms, or what the effect of
lowering the gain would be. At other times Bill and you agree because you
have learned how Bill thinks about certain matters and can anticipate what
position he will take, and not because there is only one PCT-consistent
interpretation. At yet other times you simply wait to hear what Bill's
position is, see that it can indeed follow from your understanding of PCT
and the phenomenon in question (as you understand it), and adopt that
position as if no other were possible. I think that your position on
coercion developed in this last way. To adopt Bill's PCT model of coercion,
it is not enough to understand and apply PCT to the problem, and see that
Bill's model fits. You also have to agree with Bill's particular view of
what coercion is.
Bill has taken position that coercion occurs when two control systems are
trying to control the same environmental variable and one of the two systems
(the coercer) is able to overpower the other system's control actions, so
that only the coercer is able to control the variable. This model is
consistent with one dictionary definition of the term, but are other
definitions with which this model is not consistent. Some hold that
coercion involves the coercive system forcing the coerced system to _behave_
as the coercive system specifies, either by overriding the coerced system's
outputs, or by creating severe conflict between systems within the coercee
which can be resolved only by doing as the coercer specifies ("talk and I'll
loosen the thumbscrews"). Others hold that coercion occurs only if the
behavior specified of the coercee by the coercer is "against the coercee's
will." A reasonable PCT interpretation of that phrase is the the coercee
has a goal that conflicts with that of the coercee. Under this view of
coercion, coercion cannot be taking place if the coercer demands that the
coercee do something that the coercee is willing to do voluntarily.
Given the fact that different conceptions, requiring different PCT models,
are possible, the notion that you and Bill almost always agree, simply
because you both know PCT, does not stand up to rational examination.
There's something more going on here, and I'm not going to rest until Oliver
Stone tells me what it is. (;->
