Mary provides one view of an argument, and not a bad one in my view. I happen to agree with her. But I believe she loses sight of _why_ the cybernetics folks don't much care for the 'servo-mechanism' crowd and why the 'servo-mechanism' crowd doesn't care much about the 'cybernetic' one.

Marc Abrams (2005.03.24.1735 EST) –
I believe the difference between the two camps is strongly related to how much is known about mathematics and control theory.
Richardson had a slightly different take on it. Although he spoke about those differences, even among the various types of engineers involved (industrial vs. communications) he suggested the major differences boiled down to different world views between them. I quote from pg 165 in FeedBack Thought in the Social Sciences;
"Thus we have the distinct possibility that our two feedback threads in
the social sciences mirror something of a split in the use of feedback in
engineering. The cybernetics thread emphasizes aspects more connected
to communications theory, particularly in its concern for randomly varying system inputs. The servomechanisms thread is more associated with control theory as, for example, in its emphases on behavior generated by the regulatory system itself and on the significance of nonlinearities.
But more importantly, something of the difference in worldview that
discernible between our two threads shows up in differences between
the communication theory and control theory points of view in engineering as well. The significant behavior of variables in a communication traces most directly to the behavior or shape of the incoming “wave form,” the input signal. Social scientists in the cybernetics thread tend to look outside the system for the causes of system behavior and for the regulatory structures in social systems designed to maintain control, homeostasis, and adaptability. In contrast, the significant behaviors in a servomechanism are the transients that are triggered by an input to the system but whose pattern over time traces not to the input but to the internal structure of the control system. Similarly, the social scientist in the servomechanisms thread tends to see dynamic behavior as a consequence of a system’s internal feedback structure. The fundamental points of view that help to characterize the feedback threads in the social sciences may well have origins in engineering itself.
These are very suggestive ideas, but they must remain at the level of
speculations in this investigation. We shall have to be content with three
quite reasonable hypotheses for the origins of the differences in
: use of the feedback concept in the social sciences:
- the background of the social scientists first drawn to the feedback
concept, 2) the nature of the problems they preferred to address, and 3) a split in the use of feedback concept within engineering itself.
Whatever the reason, by 1960 a fundamental difference in point of view seperates the two threads."
The less a person knows about such subjects, the stronger the person’s arguments tend to be that we don’t need mathematics or control theory to understand human organization. This is understandable as a way of defending one’s knowledge about human organization. The only alternative would be to conclude that what one knows is superficial or wrong. Of course that could be the truth, but how many people are happy to admit that?
In lieu if what Richardson said above I think this is a strawman.
Characterizing the difference as being between “cybernetics” and “servo-mechanisms” (as many cyberneticists do) shows how superficial the understanding is on the cybernetics side. The same idea, negative feedback control, encompasses both sides.
You seem not to have read Richardson’s book, nor understand why he made the split as he did. I won’t bore you with the details because you obviously are not interested.
Was the sole purpose of attending the conference to attract adherents and being shown to be right?
Is that a question or just your way of asserting something insulting and then putting a question mark at the end?
No. I’m not quite sure why you perceive every question I have as some kind of sneer or insult. I ask because I want to know things that I currently don’t know or understand. Of course this is something you never have a problem with.
The purpose of attending that cybernetics meeting, as in attending and giving papers (including invited papers) at several previous (and subsequent) ASC conferences, was to find colleagues in a field where the founder called his subject matter “Control and communication in the animal and the machine.” We who attended thought they would be interested in “control.” They weren’t. We attended their sessions; they ignored ours.
Why did they not attend yours? Do you really know? Did you ever ask anyone what the problem was? Judging from your response at the top of the post you have no real clue.
I know for a fact that Cliff Joslyn was on CSGnet a time and he was and is a big cog in the cybernetics movement. Why did Cliff leave CSGnet? Because of his lack of a mathematics background? You wish you had his math background.
New ideas are _always_ treated with skepticism in science and the reasons are obvious. If you have a 'new' idea that means you are _deviating_ from the norm, or what has been commonly accepted as valid. _CONTROL SYSTEMS_ do not like deviations _or_ deviators. You can ask me _all_ about this one. <big smile>. You can also ask the gentle men voted out of office. <big smile>
There is a difference between those who deviate as a result of learning something new, and those who deviate through ignorance.
Who decides which is which, and exactly what is the difference?
The PCT people were very familiar with the cybernetic ideas put forth at ASC conferences. The ASC people, with a few notable exceptions, were ignorant of control theory; the most vocal objectors thought it was about how to control other people, and they did not want to hear about it. Heinz von Foerster thought that “hierarchy” was about social hierarchies, and since he hated social hierarchies he sneered at the idea.
So? Big deal, a few folks had problems with what you did. I guess you really are that thin skinned. Sure doesn’t sound like a reason to circle the wagons and call in the calvary.
Nor from anything else I have said since, except perhaps what you have imagined me to say.
Wrong. It is what you don’t say and it is what you don’t encourage others to do that says you have etched PCT in stone.
It seems every time you try to collaborate with someone the relationship falls apart. From your initial 2 partners, through Bourbon and others. The only one to hang on is Marken and that is because he worships you.
You have a real big ego problem my friend. I’m not sure when you fell in love with your own ideas but I have a feeling it was very early on and your two initial partners wanted no part of it.
You cannot compromise, and you are unwilling to listen to ideas that might actually challenge a position you have taken. Your obsessive need to be right fits right in with Marken and you two deserve each other and the mud hole you currently occupy
So I ask rhetorically, why have you spent 35 years trying to etch this idea of yours in stone rather than trying to ascertain the truthfulness of your ideas?
That is a truly awesome distortion of what I have been doing. I can cite about two dozen major tests of PCT ideas that I have implemented as experiments and offered for public scrutiny over the last 35 years.
No Bill, in 35 years you have yet to show the existence of any hierarchy, or any levels as you perceive them to be. In fact, you have yet to show that your ideas about ‘perceptions’ are valid as well.
What you have shown, at least to my satisfaction, is that the control of perception is a valid idea. You have yet to show that your blueprint (PCT) is in fact a (not even the) just a viable physiological idea.
Every time someone tries one of the demos, they are testing the theory, and if it is wrong the tests could easily fail.
No Bill, they are NOT testing the ‘theory’. They are possibly validating the existence of control. PCT on the other hand is a good deal more involved then that, because every time they do one of your demo’s they are ALSO validating the TOTE model from Pribram as well, and Forrester’s, and …
What you take for “etching this idea of yours in stone” has been merely to insist that if someone wants to criticize my ideas, they should know what those ideas are and not distort them into something else.
I know 'em, and I DON’T distort them. But I’m sure they provide a VERY loud bang in your head every time you see them.
I’ll listen to any criticism of what I have actually proposed and demonstrated,
Listening is NOT the issue here. DISCUSSON is. You refuse to discuss the idea’s others may have that differ from yours. _EVERY damn question is viewed as some kind of challenge to your manhood.
It is my contention that there are _many_ ways of approaching the _PROBLEM_ of the Perceptual Control of Behavior. Should I be ostracized because I have a different way of thinking about it?
but when people put words in my mouth and object to things I have never said, I don’t have much patience. For example, you said
To which I reply, I don’t support the idea of Perceptual Control of Behavior and never said that I did, so if you want to have a different idea about that I’m all for it.
S_T_R_A_W_M_A_N.
This is your favorite type of response. When you can’t answer a question you come back and distort it out of proportion.
I say that people produce behavior in order to control perceptions;
Yawn, Yawn, big deal. You and about 3 dozen other folks, some long before you. Karl Pribram for instance. R.W. Ashby is another who talked about the control of inputs long before you. In fact ALL servo-mechanism folks control their ‘inputs’.
Your mathematics is ABSOLUTELY identical to Jay Forrester’s negative feedback loop in SD and every other servo-mechanism model.
Your claim to fame was your BLUEPRINT of the human nervous system called the hierarchy. It hasn’t quite panned out has it big boy? Am I still ‘distorting’ the facts? Which ‘levels’ have been substantiated and where can I find the data to support the claim?
if you have objections to that idea you should state them,
I just did. What is your reply? I can’t wait to hear about it.
but please don’t spread the word that I claim that perceptions control behavior.
Believe me, I may hang around CSGnet for my own amusement, but I wouldn’t let anyone within ten feet of your work, let alone tell anyone about you.
If I “ostracize” you it will be for getting the very basis of PCT wrong and criticizing me for ideas I don’t believe.
I mispoke, and YOU KNOW IT. It seems the only time you respond to me is to take a VERY cheap shot at me. This time it won’t work. Why not try answering just a few of the questions instead of trying to hide under a rock? In fact how about answering just ONE of 'em. I doubt you have the stomach for the exchange.
···
I expect that I will regret having departed from my policy of ignoring you.
Gee, I wonder why you might ever think that. I guess it’s time to start ‘ignoring’ my posts again.
