chapter  8
The large scale world and the classical limit of the quantum theory
Pages 18

We have been discussing what may be called quantum reality as existing on its own without needing any observers, but capable nevertheless of containing observing instruments. We have suggested in several places that there is a continuous transition between this total quantum reality and the large scale world of ordinary experience. The question before us now is whether we can explain how this large scale world as a whole comes out of the basic quantum laws, or at any rate, those features of this large scale world that can be described in terms of classical physics. In other words, is classical physics contained in our interpretation of the quantum theory as a limiting case?
