ABSTRACT
For Savage, this emphasis on behavior rather than belief represents a direct approach to his goal: a "theory of consistent decision in the face of uncertainty."3 But for Ramsey, who (like Keynes) defined the subject of his inquiry as "the logic of partial belief,"4 it might seem roundabout. Ramsey is certainly correct in stating that partial belief, or degree of belief, "has no precise meaning unless we specify more exactly how it is to be measured."5 But why should it be measured in terms of preferences among actions, which depend not only on degrees of partial belief but on values of outcomes? Why not simply ask a person to compare his degrees of belief in two propositions or possible occurrences and to tell us his judgment?
