- Oded Maler (921226)--
-
- I do like your sensible and realistic comments. Of course not
- everyone is interested in PCT. And of course play is necessary --
- doing things that have no immediate application, just to enjoy
- the truth and beauty of whatever one can discover.
-

-
- This is all true. I trust you aren't saying that ALL of the
- studies of arbitrary systems will prove to be relevant and
- applicable to understanding human behavior.
-
- >The world (at least not all of it) does not turn around the
- >PCT-non-PCT controversery in the explanation of human behavior.
- >This hard fact do not under-determine the *objective* beauty
- >and power of PCT, nor its importance as a stage in the
- >development of human understanding. But not realizing this, and
- >classifying all the rest of the world as "us" and "them" might
- >lead an untrained observer to perceive a peace-loving other-
- >cheek-turner as a fanatic.
-
- A little fanaticism is appropriate if it's limited to the
- boundaries of the PCT-non-PCT controversy. You need some kind of
- support structure when there are so many people who look on your
- views with disdain, condescension, and irritation, apparently
- believing that this is how science is supposed to work.
-
- >On another topic, I'm reading Sacks' "The man who mistook his
- >wife for a hat" and although apparently the author does not
- >know that ..., I think it is really worth reading. It might be
- >intersting to try to give PCT crude explanations of the
- >phenomenon he describes.
-
- The literature of mental malfunction must be rich with
- possibilities for the furtherance of HPCT. To make use of it,
- however, there must be people willing to sort through the
- mountains of information available to look for dependencies among perceptual
- processes and begin the enormous task of drawing the
- map we need. A large obstacle is the fact that the behavioral
- deficits that have been found have been characterized without any
- coherent model in the background. We need a systematic approach
- to this subject with model-relevant experiments used for
- diagnosis instead of rather casual subjective impressions of what
- is wrong. It may be that even with all that data available, the
- facts that we need to know simply have not yet been observed.
-
- >The following is a cross-posting from the Control (in the
- >mathematical engineering sense) mailing list. It contains
- >titles of all papers in the subject published recently. Just
- >for information I don't claim anything will be relevant.
-
- If you wanted to make me feel ignorant, you certainly succeeded.
- How I wish that I could understand all that stuff! The next great
- leap forward in PCT is going to be generated by a person who is
- comfortable with those advanced mathematical treatments, AND who
- has a clear idea of the phenomena of behavior that need to be
- explained. That person hasn't appeared yet, and probably won't
- until the basic concepts of PCT have been accepted widely enough
- that a person could devote a career to it.
-
- I would love to write a paper for journals like these explaining
- what we are trying to do with PCT and how people with such great
- talents could contribute to the work. But such a paper would have
- to be written by someone who speaks the language; anything I
- wrote would be considered too simple-minded even to be
- interesting to the readership. PCT needs translators; people like
- Gary Cziko and Hugh Petrie in education, and McPhail, Tucker, and
- McClelland in sociology, and Robertson and Goldstein in
- psychotherapy, and Ford in counselling and social work, and Nevin
- and Andrews (and more) in linguistics, and Forssell and Soldani
- in management consulting, and Martin Taylor and the various Gangs
- (of 1, 3, or 5) in the design of complex systems, and Cliff
- Joslyn and his cohort in cybernetics, and Rick Marken in (now)
- human factors, and Tom Bourbon in neuropsychology, and all the
- rest who have a foothold in two worlds, one of which is PCT.
-
- The world of psychology seems almost closed to PCT, but
- psychologists are not the only ones who are trying to understand
- human nature. PCT can spread to other disciplines, and is doing
- so. In every case, however, this spread has been none of my
- doing, but the doing of others who can take the basic ideas to
- their own colleagues and explain them in relation to the
- interests of those other disciplines. There always remains the
- problem of displacing the old concepts of human behavior,
- traceable mostly to conventional psychology and biology, but this
- is done most easily by people who grew up with those ideas and
- understand how they look to those who have adopted them.
-
- We lack biologists and biochemists and control-system engineers,
- among others. Maybe these, along with psychologists, are the
- toughest nuts to crack because of the direct contradictions
- involved in biology, and the implied competition in control engineering. If
- anyone knows people in these fields who might be
- willing to join in, by all means try to recruit them.
-
- And you, Oded. Are you all alone in your appreciation of the
- concepts of PCT? Do you have any colleagues who show any
- interest?
