   In Weyl’s view mathematics simply lies – as it did for Brouwer – within the Ego’s “lighted circle of intuition” and so is, in principle at least, completely presentable to that intuition. But the nature of physics is more complicated. To the extent that physics is linked to the transcendent world of objective reality, it cannot arise as the direct object of intuition, but must, like the transcendent world itself, be presented in symbolic form; more exactly, as the result of a process of symbolic construction. It is this which, in Weyl’s vision, allows us access to to the "objective" world presumed to underpin our immediate perceptions.
