1 " Again, if there is to be change of change and becoming of becoming, we shallhave an infinite regress. Thus if one of a series of changes is to be a changeof change, the preceding change must also be so: e.g. if simple becoming wasever in process of becoming, then that which was becoming was also in processof becoming, so that we should not yet have arrived at what was in process ofsimple becoming but only at what was already in process of becoming in processof becoming. And this again was sometime in process of becoming, so that it is notyet in process of becoming in process of becoming. And since in an infinite seriesthere is no first term, here there will be no first stage and therefore no followingstage either. On this hypothesis, then, nothing can become or be moved or change.Again, if a thing is capable of any particular motion, it is also capable of the corresponding contrary motion or the corresponding coming to rest, and a thingthat is capable of becoming is also capable of perishing: consequently, what is inprocess of becoming in process of becoming is in process of perishing at the verymoment when it is in process of becoming in process of becoming; since it cannotbe in process of perishing when it is just beginning to become or after it has ceasedto become; for that which is in process of perishing must be in existence.
