He denied not having one.  Most of the time, people don't outright lie
on Usenet.  They twist and turn, answering direct questiongs evasively
and inadequately, and assert half truths.

My working theory at the moment is that WM has some university degree
which had a small component of mathematics, but that part of his degree
didn't cover rigorous analysis or rigorous set theory, or anything much
else rigorous.  His outpourings on this newsgroup (as well as on its
German counterpart) pretty much rule out systematic study of the
foundations of mathematics.

Maybe WM would like to clarify exactly what his university degree
consisted of.

Indeed.
