I had in mind the Goedelian notion of incompleteness as well as the awareness that physicists are building an unending progression of ever more unified theories, from Newtonian Mechanics to Special Relativity to General Relativity to Unified Field Theories toward the current goal of a Grand Unified Theory. It is interesting to note the see-saw leap frogging between the development of new branches of mathematics, and their application to theoretical physics. (Perhaps Matthew Wiener could help me illustrate this hand-in-hand evolution. It is not an accident that Newton invented the Calculus. It was a necessary tool of thought for his elucidation of the laws of motion.) I am troubled by Popper's suggestion for a paradigm of attempting to falsify theories. In my view every theory is an approximation to the subtleties of nature. The goal is to evolve the theories to ever larger scope and to ever finer resolution of subtle detail. I prefer the method of Socrates to the method of Popper for stimulating the evolution of knowledge. (I prefer it, because it is both more effective and more civilized.) However, I accept the reality that others will prefer the more aggressive approach. It's a regrettable fact of life that humans cannot easily escape their more primitive traits of human nature.
