  Weyl (1949a, 75) notes, “The objectification, by elimination of the ego and its immediate life of intuition, does not fully succeed,  and the coordinate system remains as the necessary residue of the  ego-extinction.” However, this residue of ego involvement is  subsequently rendered harmless through the principle of  invariance. The transition from one admissible coordinate  system to another can be mathematically described, and the natural  laws and measurable quantities must be  invariant under such transformations. This, Weyl (1948, 336) says, constitutes the general principle of  relativity. Weyl (1949a, 104) says:
