Ramsey's Representation Theorem

Abstract

This paper reconstructs and evaluates the representation theorem presented by Ramsey in his essay ‘Truth and Probability’, showing how its proof depends on a novel application of Hölder's theory of measurement. I argue that it must be understood as a solution to the problem of measuring partial belief, a solution that in many ways remains unsurpassed. Finally I show that the method it employs may be interpreted in such a way as to avoid a well known objection to it due to Richard Jeffrey.
