  Zeno’s brilliant paradoxes are generally accounted as attempts to defend Parmenides. We will not look at these in detail, but his paradox of the arrow is relevant to what follows. This is the argument that an arrow in flight could not really be moving because at any given instant it would be at a place identical with itself (and not another place); something at just one (self-identical) place could not be described as moving, and an arrow which is motionless at every instant in a temporal interval must be motionless throughout the interval. Discussion of this subtle argument is deferred until discussion in a later section of Graham Priest’s position, which turns on similar premisses.
