The human body consists of countless different cells and they are by far not all human - the ratio is actually about equally human and inhuman cells. The rope represents the body, that seems to be just one consistent homogeneous object. If you start splitting it in half you can see how small the parts get. The smaller splits are then representing all different kinds of cells that together form my body, my mind, myself. It has to be, I have to be, more than the sum of my parts.
