Exactly. That's why I expressed myself contrafactually.

It's not an hypothesis unless it can be disproved. That's why I call it a
postulate and can entertain the notion that it's unnecessary.

I don't think the assumption of realism can collapse, because I don't
think it can be disproved. It's a postulate that can be maintained or not,
neither more nor less natural -- and therefore neither more nor less
supernatural -- than any other postulate. Assumptions of realism belong in
metaphysics (along with scriptural mandates and creation myths), not in
The bottom line is that scientific results don't have to be true, under
any reasonable definition of 'true'. They only have to be useful. Any
amount of perfectly useful science can be done without maintaining any
