- >to the entire list instead.
-
- This is what the list is for. Bill is not the only one who will
- appreciate your thoughtful post. If you want to apologize, do so for EVEN
- THINKING of depriving the rest of us of your contributions.
-
- By the way, have you taken the time to read Ed Ford's book "Freedom from
- Stress?" What did you think of it? Did you find it helpful? How can such
- an introduction be improved? What questions (if any) does it open but not
- answer? Ed and I would like to know.
-
- -----------------------------------------------
- With reference to the discussion between Rick and Martin, as well as
- Bill's and Oded's postings, I would like to resubmit my chart of Dec 14.
-
- What does "THEORY" mean to you?
-
- APPROACH LEVEL OF TYPE OF
- TO THEORY SCIENCE KNOWLEDGE
-
- Type 1 Hunch, expectation Common sense / What works
- based on experience. Statistical (sometimes?)
- Intuitive / Formal research
-
- Type 2 Explanation, Engineering Why it works
- prediction, test. science (always?)
-
-
- Type 3 Logical reasoning. Abstract Abstraction
- science
-
- ---------------------------------------------------------------------
- Continued to the right.
-
- METHOD OF TIME TO PREDICTION RESULTS
- LEARNING LEARN CAPABILITY
-
- ..1 Trial & error / Long Poor Spotty
- data collection
-
-
- ..2 Create theory, Short Excellent Confident
- test theory
-
-
- ..3 Deduction Short Depends on Depends
- fit with fit with
- type 2 type 2
- ----------------------------------------------------------------------
-
- Cause-Effect is in the category of an Engineering science. Type 2.
- Information theory etc. is in the category of Abstract science. Type 3.
- Control Theory is in the category of an Engineering science. Type 2.
-
- The abstract sciences (math, geometry, information theory, etc., etc.),
- have NO connection to Boss REALITY. They cannot be tested, since they are
- logical constructs ONLY. Their "validity" and usefulness depends ENTIRELY
- on their application in support of a type 2 theory, which DOES have
- connection with Boss REALITY.
-
- The Cause-Effect engineering theory has failed more than once, but even
- though the experimenters have read Karl Popper, they WANT to interpret
- their "data" as supporting their theory. As Jean Luke Picard of "Star
- Trek" fame so appropriately commands when someone has made a suggestion:
- "Make it so!" "(Control for that perception)!" - "Proof" is found.
- (Ref: "Skinners mistake" by W.T. Powers, CSG-l March 3, 1991)
-
- As Rick and Martin now agree, it is the application of an abstract theory
- (about which one otherwise can make NO value judgements) to a FAILED
- engineering type theory, that created at least some of the previous
- disagreements. (Certainly, the abstract theory being applied to the
- engineering theory has to be appropriate to be useful).
-
- What is needed above all is sound engineering theory. When it comes to
- behavior, it is called PCT. If and when PCT fails once, we will not
- ignore Popper, but modify PCT.
- ---------------------------------------------------------------
-
- In the spirit of the season, I too wish everyone a time of appropriately
- chosen perceptual references, allowing yourself and others enough
- perceptual degrees of freedom, effective action on whatever Boss REALITY
- is out there and satisfying perceptions of it.
-
- Your choice: It's all perception / It's all control / All of the above
-
- Best, Dag
