Abstract

A temporal levels structure for temporal metaphysics is outlined and employed to convey a dilemma threatening the temporal collapse of Growing-Block Theories to their meta-temporal level. The outline further explains how Presentism occupies a privileged position in that temporal levels structure. Moreover, that dilemma relies crucially on the acceptance of productive causation as explaining additions to the growing block, for which it is argued any reasonable growing-block theory should incorporate. The dilemma’s first horn considers growing-block theories where productive causes are only so when present; the second, growing-block theories where productive causes continue being so when past. Either way, growing-block theory collapses into Accruing-Present Theory: whereby all entities survive into succeeding present “blocks” of existents. It is argued, the presentness of surviving entities undermines their intended theoretical role, undercutting motivations for believing accruing-present theses. Ultimately, I recommend rejection of both growing-block and accruing-present theses based on these explanatory inadequacies.
