believe that [WM]'s shown ZFC to be inconsistent?
I don't believe that WM has a proof of ~Con(ZFC). Otherwise
there wouldn't have been any reason for me to even bring up
Nelson in the first place, for WM's proof would suffice.
The reason I brought this up is that I was trying to find out
whether anyone who says that ZFC is inconsistent would be
villified on sci.math, which would include Nelson if he could
complete his proof of ~Con(PA), or whether only those who
say that ZFC is inconsistent but can't prove it, like WM,
would be villified on sci.math. In other words, is one called a
"crank" for _saying_ ~Con(ZFC), or for saying ~Con(ZFC)
_without_proof_? If the former, then Nelson would be equally
villified for proving ~Con(PA) and ~Con(ZFC), but if the latter,
then he wouldn't.
