Stage universalism, voints and sorts

In the current debate on how ordinary objects persist through time, more than one philosopher has endorsed the following two theses: stage theory and diachronic universalism. In this paper, I would like to offer a solution to the problem (related to lingering properties) that Balashov poses to the joint acceptance of these theses. I will also offer a number of reasons why, even if it is not necessary to undermine Balashov’s counterexamples, stage theorists can, without making their theory less appealing, reject Balashov’s understanding of sorts, which plays a crucial role in his criticisms of stage universalism.
