If one is fundamentally committed to f.o.m. and is interested in other
topics only insofar as they advance the f.o.m. agenda, then I agree that
WIS doesn't accomplish much other than to turn the spotlight onto the
problem of minimizing commitments.
However, even though this is basically a "negative" achievement rather
than a "positive" achievement, I consider it to be a pretty significant
achievement, because I think that mathematicians, generally speaking,
are not only unaware of their commitments, but have a strong tendency to
deny that their own commitments involve drawing a somewhat arbitrary
line in a continuum of possible commitments. Most rabid skeptics of
infinite set theory, and rabid skeptics of the consistency of PA, and
rabid skeptics of arbitrarily large integers, strike me as being rather
similar at an emotional level: They feel that they have figured out
where all the monsters live, and have found the canonical boundaries of
an absolutely safe, monster-free haven. It's no minor achievement to be
able to show that there is no canonical place to draw a line, even way
down at the low end.
