Flow Fragmentalism

In this article, we articulate a version of non-standard A-theory–which we callFlowFragmentalism–in relation to its take on the issue of supervenience of truth on being. Accordingto the Truth Supervenes on Being (TSB) Principle, the truth of past- and future-tensed proposi-tions supervenes, respectively, on past and future facts. Since the standard presentist denies theexistence of past and future entities and facts concerning them that do not obtain in the present,she seems to lack the resources to accept both past and future-tensed truths and the TSB Principle.Contrariwise, positions in the philosophy of time that accept an eternalist ontology (e.g., B-theory,moving spotlight, and Fine’s and Lipman’s versions of fragmentalism) allow for a“direct”superve-nience base for past- and future-tensed truths. We argue that Flow Fragmentalism constitutes amiddle ground, which retains most of the advantages of both views, and allows us to articulate anovel account of the passage of time.
