Context

“They think they are saying something by these vague expressions—universal force, essential motion—but they are saying nothing at all. The idea of motion is nothing more than the idea of transference from place to place; there is no motion without direction; for no individual can move all ways at once. In what direction then does matter move of necessity? Has the whole body of matter a uniform motion, or has each atom its own motion? According to the first idea the whole universe must form a solid and indivisible mass;” source
