I have read thousands of books but never found one that was a landscape as opposed to a map. Every page of theirs is flat, but life itself is not. Why would I, a three-dimensional creature, take as a guide the two dimensions of an ordinary text? Where will I find the cubical page where reality is modeled? Where is the hypercubic book whose covers gather the hundreds of cubes of its pages? Only then, through the tunnel of cubes, can we escape from the suffocating cell, or at least breathe the air of another world.
