  On the other hand, the angles between two stars determine the  objectively indescribable subjective experience of  the observer. Moreover, Weyl says, “there is no difference in  our experiences to which there does not correspond a difference in  the underlying objective situation.” And that difference is  itself invariant under arbitrary coordinate transformations. In other words, an observer’s subjective experiences supervene on the invariant relationships and structures of a symbolically constructed  objective world.
