ABSTRACT
Charles Sanders Peirce articulated many versions of his pragmatic maxim—shorthand ways of expressing a sophisticated account of what it takes to understand or get clear about a concept. Peirce takes his contribution to the debate to identify the important third grade of “clarity.” Peirce offers a sophisticated account of what kinds of consequences a belief must have—for instance, beliefs about the world require consequences for the world, but beliefs in mathematics require consequences in proof or diagrammatic contexts. In 1926, Frank Ramsey wrote two important papers, “Truth and Probability” and “Facts and Propositions,” both heavily and explicitly threaded with Peirce’s thoughts. He argues that truth is an attribute of a “mental state” such as a belief, judgment, or assertion and “if we have analysed judgment we have solved the problem of truth”. Hans-Johann Glock would prefer Ramsey to stick to the redundancy thought.
