 However, presentists shouldn’t celebrate too early. They should remain cautious. Deasy goes on to raise an independent concern with how to define presentism. Echoing a challenge from Timothy Williamson (2013: 24–25), Deasy objects that there’s no satisfactory way to spell out what’s meant by “is present” in the definition of presentism. Further, we may also need to say something about the duration of the present (see Gentry 2021).
