Oh, no, by all means, use "web of belief". In fact I prefer it. It
just doesn't matter where your beliefs come from or mine. It's the
destination that counts and not the source. Whether it comes from
church or Quine or Wittgenstein is irrelevant to whether it's true or
false.

If you use your web of belief as the standard of truth, you're going
at the problem backwards. Any two-bit philosopher can use his web of
beliefs as justification for what he believes and most do. It's so
much easier than proving them true or false in universal terms.

Except there's no reason to change the term I used since it said what
was meant.
