Baldwin replies:
ZFC is quite successful has providing a groundwork for mathematics. But
rather than providing a context for investigating `foundational questions'
in mathematics as practiced it has become another branch of mathematics
(replace `model theory' by `set theory' in Friedman's characterization of
Baldwin's view of model theory.)
The general explanation by model theorists of the Borel Tits Theorem is
a more
direct contribution to the foundations of algebraic geometry and group
representations than results about measurable cardinals.
(See Poizat: Stable groups Chapter 4.)
(Incidentially, some one more knowkedgeable could easily come up with
example from recent work in descriptive set theory which is just as
good an example of a contribution to the foundations of analysis or
group representations.)
