  It is the freely created pure numbers, that is, pure symbols,  according to Weyl, which serve as coordinates, and which provide the  material with which to symbolically construct the objective world. In symbolically constructing the objective world we are forced to  replace space and time through a pure arithmetical construct. Instead of spacetime points, \(n\)-tuples of pure numbers corresponding to a given coordinate system are used. Weyl (1948, 303) says:
