A plurality of points became the “building blocks” with which the mathematicians of the day before microscopes imaginatively constructed their lines. “Lines” became the one-dimensional, substanceless “logs” that they floored together in their two-dimensional, planar, thicklessness “rafts.” Finally they stacked these planar rafts one upon another to build a “solid” three-dimensional “cube,” but having none of the essential characteristics of four-dimensional reality — i.e., having neither temperature, weight, nor longevity.
