- It's pretty late for me but this comment woke me up.
-
- i'm flattered you read me so closely ;-}.
-
- In PCT, "purpose" is virtually synonymous with "control". Actually,
- the common sense of the word "purpose", as in "behaving with a purpose"
- or "his purpose was to" is synonymous with PCT's "reference level of
- a controlled variable".
-
- i think this ``virtual synonymy'' is a rhetorical move of pct's that
- irritates people w/ a scientific bent (like me). i'm quite willing to
- accept yr control models of concrete and reasonably well-understood
- phenomena. i find yr generalization to everything else, including the
- kinds of things implied by ``purpose,'' completely unwarranted. so i
- wish you'd stick to making claims you can justify....
-
- cheers.
