Mysteries Without Mysticism, Correlations Without Correlata, Epistemology Without Ontology, and Probability Without Causality
This chapter considers the nonclassical version of Bohr’s interpretation of quantum phenomena and quantum mechanics as complementarity, developed by him in terms of his concepts of phenomena and atomicity following his exchange with EPR, and the view of probability arising from this interpretation or, more generally, from the nonclassical epistemology of quantum theory. Section 10.1 offers a commentary on “quantum mystery.” Section 10.2 addresses the nature of quantum correlations as “correlations without correlata.” Section 10.3 is a discussion of quantum epistemology as epistemology without ontology via the irreducible role of measuring instruments in the constitution of quantum phenomena, and Bohr’s concepts of phenomena and atomicity. Section 10.4 considers quantum probability as a nonclassical form of Bayesian probability. It includes a discussion of Einstein’s arguments concerning the incompleteness of quantum mechanics as, in his view, only a statistical theory of ensembles rather than a theory describing individual quantum processes.
