Time, Change, and Existence

There are considerable obstacles to expressing change in existence in an unambiguous formal language.  I think the best response to these problems is to adopt what I call a minimal A-theory—a theory of time that treats all change as a variant of property change.  I’ve developed such a theory and defended it from objections.  I also argue against the prevailing assumption that A-theoretic views of time require an logic with tense operators.  I propose an alternative to the usual Priorian tense logic that dispenses with operators.  I’m interested in the benefits of such a system both from a formal standpoint and with respect to understanding the nature of properties more generally.  More recent work considers how minimal A-theorists reason about the puzzles of diachronic personal identity.  I’ve also written several short pieces comparing the minimal A-theory to competing “spotlight” accounts of time.  And I am currently working on a piece about how abductive arguments should (and shouldn’t) be deployed in building theories of time and modality.
