Reason

Take anything the human eye can see and decide where the center is. Then split it at the center - you get two centers. Do the same with those remnants and you'll get 4 centers - 1 for each object that is derived. We can go on and on until we find something that can't be split, which defies the recursion. Our logic allows us to split things as long as they have a center... but does that something that can't be split not have a center? If it's physical, it would have a center.
