 Perdurance theorists, who assimilate identity over time to identity over space, can accommodate vagueness in identity over time in the same way. In Hawley’s example they can say that there are several entities present: one that exists before and after the identity-obscuring occurrences in the cabinet, one that exists only before, and one that exists only after. It is indeterminate which of these is a person and so it is indeterminate what the singular terms “Alpha” and “Omega” refer to.
