WebNevertheless, this is the move that Bohr appears to make, maintaining that the "conditions" (which define the possible types of predictions regarding the future behavior of Niels' system) "constitute an inherent element of the description of any phenomena to which the term ‘physical reality’ can be properly attached" (Bohr 1935a, p. 700).
