Employs nothing at all The man of today planes to perfection a board with a planing machine in a few seconds. The man of yesterday planed a board reasonably well with a plane. Very primitive man squared a board very badly with a flint or a knife. Very primitive man employed a unit of measurement and regulating lines in order to make his task easier. The Greek, the Egyptian, Michaelangelo or Blondel employed regulating lines in order to correct their work and for the satisfaction of their artist’s sense and of their mathematical thought. The man of today employs nothing at all and the result is the boulevard Raspail. Le Corbusier, Towards a New Architecture The Nature and Art of Workmanship tools
