Belief Revision, Uniqueness and the Equal Weight View

Abstract

Thomas Kelly has argued that the Equal Weight View of peer disagreement is committed both to belief revision and to the Uniqueness Thesis, which claims that for any hypothesis H and a total body of evidence e, there is some one-doxastic attitude that is uniquely rational to adopt towards H. I rebut both theses and I also defend the view that in Kelly's case the Uniqueness Thesis doesn't require belief revision.
