  12. the Riesz representation theorem is perhaps the mathematical "keystone" that connects our pictures of the discrete and continuous worlds. without this theorem, mathematicians could not have rigorously defined integration over expressions involving Dirac delta functions (something that physicists had first intuited without proof).

    It allows us to transfer ideas about inner product spaces over to their dual spaces of linear functionals:

  27. It is important to note that the context of the quotation shows that Dirac was arguing that mathematical beauty was a reason to have faith that a theory would in the end turn out to be correct — despite present contrary experimental evidence — when further insights or experiments brought theory and evidence back into alignment.

    Dirac was drawing a moral from a time when Schrödinger had been discouraged from publishing the relativistic version of his wave equation because of a disagreement with evidence, which was later resolved.
