Abstract

The paper purports to show that truth-atemporalism, the thesis that truth is timeless, is incompatible with power to do otherwise. Since a parallel and simpler argument can be run to the effect that truth-omnitemporalism, the thesis that truth is sempiternal, is incompatible with power to do otherwise, our conclusion achieves greater generality, and the possible shift from the claim that truth is omnitemporal to the claim that it is atemporal becomes useless for the purpose to resist it. On the other hand, our argument for the conclusion that both Atemporalism and Omnitemporalism are incompatible with power to do otherwise will be shown independent of the debated assumption that the past is inalterable. So our argument goes through independently of whether Ockhamists are right in insisting that the soft facts about the past are alterable.
