In reading D. Bohm "Quantum Theory" (1979), on p. 625 he makes the statement..."without appeal to a classical level, quantum theory would have no meaning". And then ..."quantum theory presupposes the classical level and the general correctness of classical concepts in describing this level "[e.g., the classical level--added for clarity] If I read Bohm correctly, he seems to suggest that reality must always be dialectic union of the mathematics of the classical and quantum--that is, there does not exist a "classical reality" or a "quantum reality", only a reality that is a union of the classical and quantum. Since Bohm's book is now > 35 years old, are his statements concerning relationship of classical to quantum held in 2005 to be valid ? Or, has new information since 1979 shown Bohm to be incorrect. Clearly, Bohm understood quantum mechanics, thus I cannot believe that what he said above was not true as of 1979. Thanks for any clarification that can be provided.
