Millennia ago, some genius discovered that such wiggles as fish and rabbits could be caught in nets. Much later, some other genius thought of catching the world in a net. By itself, the world goes something like this: But now look at this wiggle through a net: The net has “cut” the big wiggle into little wiggles, all contained in squares of the same size. Order has been imposed on chaos. We can now say that the wiggle goes so many squares to the left, so many to the right, so many up, or so many down, and at last we have its number. Centuries later, the same image of the net was imposed upon the world as the lines of both celestial and terestrial latitude and longitude, as graph paper for plotting mathematical wiggles, as pigeonholes for filing, and as the ground plan for cities. The net has thus become one of the presiding images of human thought. But it is always an image, and just as no one can use the equator to tie up a package, the real wiggly world slips like water through our imaginary nets. However much we divide, count, sort, or classify this wiggling into particular things and events, this is no more than a way of thinking about the world: it is never actually divided.
