There are two versions of the "pragmatic" theory of belief as a disposition to act: peirce's theory is associated with an "objectivistic" view of the theory of probability as a measure of degrees of belief, While ramsey's theory is associated with the "subjectivist" and bayesian concept of probability. In this paper it is argued that both theories share a functionalist account of belief, As dependent on desire and action, And that the normative character of bayesian decision theory is the best approach for a theory of belief as a disposition to action.
