Forgive my scepticism, but it would seem that there is no "foundation
theory". Either one must axiomatise away all semantic meaning for the
theory, or end up with one based on circular definitions of
terms. Popperian falsification is a good way of explaining why certain
scientific explanations are preferred over others, however it is not
the only one. Others would include Occam's razor, and aesthetics
(Einstein's sense of beauty). These three principle do not necessarily
point in the same direction. For example, empirical evidence
contradicting general relativity tends to be either ignored, or
analysed to an inch of its life to explain away the discrepancy in
terms of systematic or experiemntal error. The reason is because
physicists have faith that GR must be correct because of its inherent
beauty (of course if experimental evidence mounted up against GR to a
great level, then GR would either have to be abandoned or modified
(Popper's procedure) so by no means does beauty supervene on popperian
falsification, but nor is it the other way around. Similar with
Occam's razor)

I just don't see how this can be a building block of the TOE. It may
be a meta theory decsribing the theory, just as it discusses other
theories, but it is not a component.
