 Prima facie&gt;, there are myriad “cross-temporal” relations. We admire Marie Curie; admiration is a relation. Yesterday’s rain caused today’s flood; causation is a relation. There are other kinds of relation, which we discuss below, such as directly referring and truth-making, which seem like they cross times (and as if they might cause special trouble for presentism). For now though we want to consider the point very generally. Presentism is not compatible with the existence of Marie Curie or yesterday’s rainfall; presentism denies the existence of all past entities. Nonetheless, what we have here with admiration and causation seems to be a relation. It’s very natural and very reasonable to suppose that a relation can only be instantiated if all of its relata exist: x cannot stand in a relation R to y unless both x and y exist. If that’s right, then there’s an obvious worry. Presentism seems flat out incompatible with the existence of any and all cross-temporal relations. Something must give.
