 Once again, there’s clear and sustained disagreement about the effectiveness of this strategy. Suppose that we can insist sensibly that there’s a notion of “existence simpliciter” that helps presentism to avoid the challenge that P3 collapses into P2. (If this is so, then our opponent can’t tell us, simply, that P3 is false if P2 is false.) Nevertheless, this raises the question as to what, precisely, is meant by “x exists simpliciter” and whether the new notion can be used to characterize presentism.
