Phillip Bricker is a contemporary analytic metaphysician at the University of Massachusetts Amherst, known primarily for his work on modality, possible worlds, and truthmaker theory. He defends a distinctive version of modal realism that permits 'island universes'—spatiotemporally isolated regions within a single possible world—departing from David Lewis's more restrictive account. His work on truthmakers engages closely with questions about the ontological grounds for negative and general truths.
