Degrees of Truth, Degrees of Belief and Subjective Probabilities
----------------------------------------------------------------

A number of authors have noted that if we have degrees of truth, then we
should have corresponding degrees of belief---but that these degrees of
belief do not behave like subjective probabilities.  So should we
countenance two different kinds of degree of belief?  I argue that we
cannot coherently do so, and present instead a formal framework in which
there is a single notion of degree of belief, which in certain
circumstances behaves like a subjective probability assignment, and in
other circumstances does not.  The framework is surprisingly neat and
uncomplicated, and affords a clear picture of the relationship between
degrees of truth, degrees of belief and subjective probabilities.
