 In observing that the Dutch Book theorem and the DBA are sensitive to the formulation of the probability axioms, it should be noted that whereas classical logic is generally presumed, probability axioms can be formulated, with suitable adjustments, for non-classical logics. Weatherson argues that this is appropriate in representations of rational belief, and formulates axioms of probability that are built upon an intuitionistic logic, for which he then gives a Dutch Book argument (Weatherson 2003).
