Movement

[ElephntFalingOffClif]

My brother is taking philosophy in college and had me read a passage from his book that he was required to study that tryed to disprove the existance of movement. It arguues that an object can not move an infinite distance in a finite amount of time. Whatever is moved must traverse a certain distance:but any distance is divisible to infinity, what is moved must first traverse half of the distance and then the whole of it. But first it must traverse the entire half of the distance, and the half of that and the new half of the previous half. But if the halves are infinite in number, since for every whole taken it is possible to take half, then it is impossible to traverse in a finite time an infinite number of points. Then, given that every magnitude admits of infinite division, it is impossible to traverse any magnitude in a finite time.

But obviously movement does exist, else wise how would we get from one place to another?:confused:
