I am casually following the thread on arithmetical soundness of ZFC,
but feel that it has yet to move into productive channels.
Let me suggest the following question for discussion:
WE ALL KNOW WHAT A PROOF OF THE INCONSISTENCY OF ZFC WOULD LOOK LIKE:
A PROOF IN ZFC OF 1 = 0.
(As a student, I had a number of these 'proofs', sometimes convincing
enough to write down, and in one case, enough to give the family
lawyer a copy in order to be notarized and preserved).
BUT WHAT WOULD A PROOF OF THE NON ARITHMETICAL SOUNDNESS OF ZFC LOOK
WHAT WOULD EVIDENCE OF THE NON ARITHMETICAL SOUNDNESS OF ZFC LOOK LIKE?
We might get somewhere if we ponder this question.
