 However, although presentists sometimes make this move, there’s very little discussion in the literature as to whether PAN is preferable to PA (cf. Crisp 2003: 215) and, if so, what would justify that preference. (One might think that metaphysical theses are necessarily true, if true at all. But this thought is not directly connected to the debate about time and change, and it is certainly not uncontroversial, so we set it aside here.) In what follows, reflecting the lack of discussion, we remain neutral on whether PA or PAN is preferred. We follow the wider literature in typically stating presentism as P, rather than PA, though we take it that something at least as strong as PA is intended.
