Harvey, thanks for your concise put-down of second-order logic in 24
Feb 1999 20:08:49. This is a much better formulation of some of the
points that I have been trying to make.
By the way Harvey, what's your opinion of the views of your Ohio State
University colleague, Stewart Shapiro, as expressed in his book
`Foundations Without Foundationalism: A Case for Second-order Logic'?

Ye Gods, who is this guy? No matter how ignorant he is about
technical work in f.o.m., isn't he aware that Cohen won a Fields
Medal? This illustrates the kind of ignorance/arrogance/hostility
that we f.o.m. professionals have to deal with. It's a miracle that
f.o.m. still exists as a subject.
