Query: Bell's theorem and Bohr's principle that the measurement must be
  classical   In a recent paper Karl Hess and Walter Philipp claim that hidden local
variables cannot be ruled out. We argue that their claim is only valid if one
gives up Bohr's principle that the measuring instruments must be classical, and
this principle belongs to the foundations of scientific knowledge: Therefore,
nonlocal influences can be considered demonstrated.
