  It is difficult for many people to accept quantum mechanics as an  ultimate theory without at the same time giving up some form of  realism and adopting something like an instrumentalist view of the  theory. It is clear that Weyl was fully aware of this state of  affairs, and yet in all of his published work, he refrained from  making any bold statements of his views on the fundamental questions  about quantum reality. He did not vigorously participate in the  debate between Einstein and Schrödinger and the Copenhagen  School nor did he offer decisive views concerning, for example, the  Einstein, Podolsky, Rosen thought experiment or  Schrödinger’s Cat. Since Weyl held  strong philosophical views within the context of the general theory  of relativity, it is therefore only natural that one might have  expected him to take a stand with respect to Schrödinger’s cat  and whether or not one should be fully satisfied with a theory  according to which the cat is neither alive or dead but is in a  superposition of these two states.
