- * I don't like that comment.
-
- I Forgot some non-grown-ups are in the background :-)
-
- * What's wrong with established Science
- * is the establishment part, not the science part.
-
- Maybe my use of the term "cult" is not appropriate. You can decompose
- both established and non-stablished science into their "scientific"
- part (some ideal objective of increasing human knowledge concerning
- the world [if the latter exists..]) and their social/administrative/
- organizational part which is the description of how this goal is
- implemented, successfully or not, by interconnecting human beings with
- their local motivations to form a scientific community. My observation
- was that analogically to religion, established science is more like
- the Church, while PCT is more like, say, the first christians or a
- nomad empire. This was said with no regard to the "science" part of
- both. In maintaining the integrity of some non-established group of
- people you need some substitute for tenures/grants/publications, and
- this is done by promising some share in the kingdom-of-heaven and
- scientific-truth and other forms of positive reinforcement (I know
- there is not such a thing, but I could not find a better term).
-
- * I think we PCT
- * types go farther than most in sticking to the science and
- * avoiding becoming an establishment. It's only people who don't
- * ever do any experiments with real people who think that PCT is
- * just another belief system handed down from on high. The basis of
- * PCT is a set of easily reproducible phenomena that conventional
- * science has overlooked. To show that PCT doesn't follow from
- * these phenomena, you'd have to upset everything the physical
- * sciences have developed over the last 350 years or so. I don't
- * think that a system with such a strong base in phenomena deserves
- * the term "cult."
-
- I think what I said above clarifies my personal meaning of the term.
- Anyway, I don't want to sweep the dicussion to my favorite level,
- the meta-level. Not everything should be said explicitly.
-
- About the mathematics behind object perception and recognition. I
- don't have nything productive to say for the moment. I'll think and
- ask some authorities. Meanwhile I think you might find some
- inspiration in the books of the great mathematician H. Weyl which are
- probably accessible. He was concerned with the relation between the
- world and its perception/representation and he conceived abstract
- algebra as playing a fundamental role in this process of
- 'coordinatisation'.
