It would have been completely wrong to tell them that they did not understand how to build bridges, and that only people who understood Newton are able to build adequate bridges. > > Since there are many more of them than there are of us > > "Us"??? Forgive my presumption. > > Each model seems to works adequately for the modeler. > > The control engineer who rejected my paper on controlled > variables did so for the following three reasons: 1) control > systems are more properly viewed as controlling objective > states of affairs, not perceptions Perfectly understandable. We normally think that thermostats control the temperature of the room, not their perceptions of the temperature. (This is one reason we don't place a candle under the thermostat in order to save fuel costs in the winter.) 2) the presentation of > control theory was way too elementary and Definitely true from an engineer's perspective. All of PCT deals with a section of the first chapter of any text on control. 3) psychologists > already know all about controlled variables anyway. Why would you expect an engineer to know anything about what psychologists know or don't know? > Would say > that this fellow understands control theory perfectly well > because it "works for him". Yes. > Isn't it possible that there > might be a fundamental flaw in this person's understanding of > control theory, even though it "works for him"? Yes. Bruce Gregory
