Seminar on Belief and Degree of Belief

The traditional notion of belief and the formal notion of degree of belief have been central concerns of epistemology.  It has been traditional to assume that the traditional notion can be dispensed with, and that degree of belief can precisify all of the features that used to be associated with belief.  But recently, the relation between the two has come under closer scrutiny.  Some authors have thought that the way belief is reduced to degree of belief is somewhat more subtle than historically thought.  Recently, many others have argued that neither of the two notions is reducible to the other, but that they are in some way interdependent.  Few if any have attempted the reverse reduction.

Most readings are still only tentatively assigned.  Many of the dates will change, and some of the readings may as well.
