 Responses to Savage’s problem include a game-theoretic treatment proposed by I.J. Good (1983), which swaps the extensional variable that is necessarily true for an intensional variable representing an accomplice who knows the necessary truth but withholds enough information from you for you to be (coherently) uncertain about what he knows. This trick changes the subject of your uncertainty, from a necessarily true proposition that you cannot coherently doubt to a coherent guessing game about that truth facilitated by your accomplice’s incomplete description. Another response sticks to the classical line that failures of logical omniscience are deviations from the normative standard of perfect rationality but introduces an index for incoherence to accommodate reasoning with incoherent probability assessments (Schervish, Seidenfeld, &amp; Kadane 2012). A third approach, suggested by de Finetti (1970), is to restrict possible states of affairs to observable states with a finite verifiable procedure—which may rule out theoretical states or any other that does not admit a verification protocol. Originally, what de Finetti was after was a principled way to construct a partition over possible outcomes to distinguish serious possible outcomes of an experiment from wildly implausible but logically possible outcomes, yielding a method for distinguishing between genuine doubt and mere “paper doubts” (Peirce 1955). Other proposals follow de Finetti’s line by tightening the admissibility criteria and include epistemically possible events, which are events that are logically consistent with the agent’s available information; apparently possible events, which include any event by default unless the agent has determined that it is inconsistent with his information; and pragmatically possible events, which only includes events that are judged sufficiently important (Walley 1991: 2.1).
