If you are interested in joining it online, please write to events.isfi(a)usi.ch For more information: https://www.usi.ch/en/feeds/26653 Here is the abstract of the talk: Is it possible to find ordinary objects, in a relativistic world? And if yes, to what extent and at what cost? In this paper, we discuss the problem of relativistic change and how it threatens our received view of ordinary objects. More precisely, we will show how the problem arises, given two metaphysics of persistence, i.e., 4- and 3-dimensionalism, thus generalizing a formulation due to Sattig (2015). Finally, we will assess different strategies and evaluate their costs.
