Consistency is []p & ~[]~p. I was saying []p & ~p, ie mistaken

ISTM that Bruno equivocates and [] sometimes means "believes" and
sometimes "provable".
And I'm doing the same. It's not such an issue - a mathematician will
only believe something if e can prove it.
But provable(p)==>p and believes(p)=/=>p, so why equivocate on them?
Both provable('p') -> p, and believe('p') -> p, when we limit ourself
to correct machine.
(And incidentally mathematicians believe stuff they can't prove all
the time - that's how they choose things to try to prove).
Then it is a conjecture. They don't believe rationally in conjecture,
when they are correct.
