Presentism, roughly the view that only present objects exist, is intuitively appealing, and
hence worthy of serious consideration. However, according to another equally intuitive
and well-established constraint on truth, propositions require grounding, i.e. a wordly item
capable of suitably ground their truth. Given that presentists are not committed to the
existence of past objects like Caesar or dinosaurs, what could possibly ground the present
truth of propositions about Cesar or dinosaurs? Henceforth, I shall refer to this challenge
faced by presentists as the grounding objection to presentism.
In this  nal research paper, I set out to clarify such objection, carefully examine the number
of di erent answers to it, and  nally assess whether they succeed. In doing this, I shall
proceed as follows. In the  rst part, I will spell out the objection more in details, and specify
presentists are mainly faced with a particular explanatory challenge rather than with a mere
request of specifying an ontological ground for propositions about the past. Along the way,
I will also lay out some desiderata for a overly satisfying solution to the grounding objection
on behalf of the presentists. In the second part, accordingly, I'll proceed to weigh various
presentist solutions by considering how well they fare in providing e cacious explanations
for the truth of past propositions. Finally, I will set forward my preferred versions of the
solution to the objection, helping myself from a speci c reading of the notion of grounding
and also appealing to a more minimalist strategy. Crucially, the challenge will be met on
the basis of a suitable explanation of why past propositions are true
