This seems right to me.

One problem I see is that so-called foundations seems to depend
too much on technical stuff about set theory for philosophers to be
interested in and/or competent at. In fact, I'd go further. It
seems to me that set theory has been set up as *the* foundation, and
competence in its highly specialized, more difficult reaches seems a
prerequisite for philosophizing about mathematics. Therefore,
philosophers just can 't do it. So, there are a bunch of
specialists--you are one--who do set theory, and a very few of these
specialists--you are one again--happen to have strong philosophical in
terests. But, for example, stuff about large cardinals is
inaccessible to virtually all philosophers (i.e., those philosophers
who inhabit philosophy departments).
Awhile back, Steve mentioned (I think maybe as many as three
times) some fundamental concepts, such as number, function, etc. If
these topics could be effectively and interestingly discussed without
someone being reasonably expert in set theory, then these fundamental
concepts might interest philosophers. I'm not so sure of this,
About your (and Steve's) concern that math. logic is not
necessarily foundations: part of math logic is set theory, and set
theory features prominently in foundational talk. Therefore, it's
natural for people to think math logic is foundations. That is,
foundations seems to be set theory, which is also part of math. logic.
(I'm not saying this is a terrific argument, just a natural conclusion
I personally think reverse mathematics seems foundational, but
several mathematicians I've spoken to seem not to hold it in high
regard. I don't know what exactly this implies, but I'm speculating
that they don't consider it either to be "interesting" math logic or
they think it has no foundational interest.
I would be very interested in hearing what ideas you (Harvey) or
anyone else has that could fill in the intersection of foundational
topics that could engage both mathematicians and philosophers.
