  The four-dimensional space-time continuum must be replaced by a  four-dimensional coordinate space \(\mathbb{R}^{4}\). However, the  sheer arbitrariness with which we assign coordinates does not affect  the objective relations and features of the world itself. To the  contrary, it is only relative to a symbolic construction or  modelling by means of an assignment of coordinates that the state of  the world, its relations and properties, can be objectively  determined by means of distinct, reproducible symbols. While our  immediate experiences are subjective and absolute,  our symbolic construction of the objective world is of  necessity relative. Weyl (1949a, 116) says:
