A recent presentist strategy has been to deny that truths about the past need presently existing truthmakers. These presentists do not deny that such truths need grounding; they hold that each truth about the past is true because of how the world was, not how it is. This paper argues that this position faces two problems, one of which can be overcome by adopting a certain view of the property of truth for propositions about the past. The second problem cannot (...) be solved. The upshot is that this form of presentism is not a theory of truthmaking for propositions about the past. Rather, it is a theory about why such truths need no present grounding that is motivated by a novel theory of truth. (shrink)
