Your examples are thought= -provoking, but unfortunately for you
tend to push me in the other way:  "believe" is just inherently a

In short= , "{p | John believes p} is a prototypical category.
Prototype beliefs include "Aristarchus believed the
sun was at the center of the universe" and "I believe I have
money in my pocket", but what to do with "Jim (a mouse)
believes that Tom (a cat) will catch him and eat him" is a puzzlement.&= gt;

The answer seems to lie in Dennett's notion of a belief, that is, a beh= avioral category, more or less, plus some anthropomorphism: Jim behaves the= way I would if I believed that and was Jim's size and savor -- and other f= aculties.

Dennett makes some distin= ction between beliefs and opinions,
which is not krici/jinvi, but if I understand it is about what
we act on vs. what we are willing to assent to:  Jim has
beliefs but not opinions (Mickey has both); I have both;
there are many more beliefs than opinions; almost all
beliefs are true, on pain of nonsurvival; opinions can be true
or false without very grave consequences much of the time.

Actually, when Dan is consistent (and coherent) he would admit that mos= t believes may well be false but they fit together to give a good functiona= l grasp of the world -- different falsehoods cancelling one another out, as= it were.  He can be a fairly intelligible Pragmatist when pressed and= not on display (so, of course, what he means by true is something else aga= in too -- I am translating).  this belief-opinion distinction is a nic= e one and worhty of Lojbanization, but I don't know just how to do it effic= iently.

Shades of Smullyan's experimental epistemologist, whose machine
gives him access to the physiological correlates of people's brain
states.=A0 With the machine, he knows whether or not something seems
red to you -- but he gets into trouble when he applies the machine
to his own mind, and learns that he may be going crazy.>

Ray likes to push stock characters to the extreme. I assume one aspect = of his going crazy is that he thinks he can tell when something seems red t= o you or rather when someone may be going crazy.
