Is that the same philosopher (Kuhn) who died some centuries ago and
were the debaters present? Wow! and Einstein thought that *Quantum
Mechanics* was spooky.

I rather liked the objectivity, simplicity and rigor of Popper's
prescription and felt that he was verbalizing what respectable scientists
and engineers have long been doing intuitively. It was described on the site
I mentioned as:

Popper's proposed Scientific Procedure:

(1) conceive theory (can't prescribe how..a creative act)
(2) deduce effects of theory
(3) do experiments
(4) if experiment agrees with theory, go to (2)
otherwise, theory is falsified (ie wrong!)

Example: I could have a theory about the sequence 1,2,3,5,7.... It
might be that it is the sequence of prime numbers. When the next number is
an 11, I would be more confident. When the next was a 15, the theory fails
and an *ethical* scientist would consider looking for another theory (Such
as: the sequence follows increments of 1,1,2,2,4,4,...) instead of trying to
milk more $$$ from the sponsor.
