 Unsurprisingly, there are questions about the advisability of each strategy, in general, as well as about whether each can be pursued or applied sensibly in defense of presentism. Nonetheless, with the above general overview in hand, we now turn our attention to two philosophical problems that confront presentism: the problem of reference to non-present entities (§5) and the “truth-maker” problem (§6). Both are specific instances of our main objection, introduced above, and both present special problems for presentists. (The well-informed reader will note that we haven’t yet mentioned explicitly problems concerning quantification across times or metric tensed statements. We consider both as part of  §6.)
