     So Michael feels that ( \exists X (Bel(X) & ~X) ) ...but he cannot
actually exhibit such an X, because he also feels that
( \forall X (Bel(X) -> ~Bel(~X)) ).  However, he does feel that there
is a "knows" connective, with the property that
( \forall X (Kn(X) -> X) ).  Is this a good summary?  Or are you
trying to avoid syntactic systems altogether?

     I was going to add a comment, but I realized I'm out of my depth.
Can anyone suggest a good summary paper of logics which encompass the
notion of belief?
