The real price of the dead past: A reply to Forrest and to braddon-Mitchell

Non-presentist A-theories of time (such as the growing block theory and the moving spotlight theory) seem unacceptable because they invite skepticism about whether one exists in the present. To avoid this absurd implication, Peter Forrest appeals to the "Past is Dead hypothesis," according to which only beings in the objective present are conscious. We know we're present because we know we're conscious, and only present beings can be conscious. I argue that the dead past hypothesis undercuts the main reason for preferring non-presentist A-theories to their presentist rivals, rivals which straightforwardly avoid skepticism about the present.
