DURATIONS, MOMENTS AND TIME-SYSTEMS in Only events of a certain type can be members of an absolute antiprime, namely events which in Part II have been called durations. Only durations can extend over durations, and accordingly all the members of a moment are durations. -3 We may conceive of a duration as a sort of temporal thickness (or, slab) of nature*. In an absolute
- The slab of nature forming a duration is limited in its temporal
dimension and unlimited in its spatial dimensions. Thus it repre
sents a finite time and infinite space. For example let the horizontal
