I truly don't understand what you are driving at. Euclideanism as
*anti*-rigor? I think it's pretty conventional to view Euclid as the
father of mathematical rigor: definition-theorem-proof. I agree with
this conventional view. Mathematical rigor is our means of attaining
mathematical certainty.

No. At least I can't see it. Tell me, what was so odious about 19th
century foundationalism?
In your posting of 12 Sep 1998 00:43:56 you referred to

When was it discredited? Who discredited it? How?

No, this is flatly wrong. A lot of Harvey Friedman's f.o.m. research
stems from the same kinds of philosophical motivations as Frege,
Hilbert, Brouwer, et al. Don't let Harvey's talk of whoring confuse
you. But perhaps I should let Harvey speak for himself on this.
In any case, you said "Friedman et al". Well, I myself should
probably be counted as one of the "et al", and I certainly aspire to
this kind of philosophical significance in my own f.o.m. research.

I don't understand much of what you said about Stratoism. But I'm
certainly in favor of greater collaboration between f.o.m. researchers
and philosophers of mathematics. If you also want collaboration, then
why are you quasi-empiricists so hostile, even openly hostile, to what
you call "foundationalism". Is this an artifact of postmodernism,
continental philosophy, etc.?

Yes, I agree, we need to be aware of this. For a start, how about
defining what you mean by "foundationalism"?
