  Priest’s third argument (p. 218) is his version of Zeno’s arrow argument mentioned earlier. In the cinematic view of change, there is nothing about the arrow at any instant to contribute to its motion: it is indistinguishable from an arrow at rest. But then there is nothing to constitute its motion: an infinite number of zero motions does not add up to anything but zero motion. In response to the reply that according to measure theory a (nondenumerably) infinite number of points of measure zero can have a non-zero measure, Priest argues that this is just mathematics: “…it does not ease the discomfort … when one tries to understand how the arrow actually achieves its motion. At any point in its motion it advances not at all. Yet in some apparently magical way, in a collection of these it advances. Now a sum of nothings, even infinitely many nothings, is nothing. So how does it do it?” (pp. 218–9)
