Abstract

The paper argues that the formulation of quantum mechanics proposed by Ghirardi,Rimini and Weber (GRW)is a serious candidate for being a fundamental physical theory and explores its ontological commitments from this perspective.In particular,we propose to conceive of spatial superpositions of non-massless microsystems as dispositions or powers,more precisely propensities,to generate spontaneous localizations.We set out five reasonsforthisview,namely that(1)it provides for a clear sense in which quantum systems in entangled states possess properties even in the absence of definite values;(2)it vindicates objective,single-case probabilities;(3)it yields a clear transition from quantum to classical properties;(4)it enables to draw a clear distinction between purely mathematical and physical structures, and(5)it grounds the arrow of time in the time-irreversible manifestation of the propensities to localize.
