 While QBists follow de Finetti in taking all probabilities to be credences of actual agents, Healey’s pragmatist takes probabilities to exist independently of the existence of agents but not to be physical propensities or frequencies, nor even to supervene on Lewis’s Humean mosaic (see entry on  David Lewis  §5). There are probabilities insofar as probability statements are objectively true, which they may be when sensitive to though not determined by physical facts.
