Whitehead, Quantum Mechanics and Local Realism
Leemon McHenry
In his book, Nature Loves to Hide, Shimon Malin provides a wonderfully lucid and fascinating account of the development of quantum mechanics in the twentieth century and argues that the baffling puzzles of the quantum world can be understood in terms of Whitehead's process metaphysics. 1 Malin thus joins an ever-growing number of physicists who see in Whitehead's theories a useful framework for understanding contemporary physics, including for example, Henry Stapp, Timothy Eastman, Lawrence Fagg, Basil Hiley and David Finkelstein.Nature Loves to Hide is divided into three parts: "e Quandary," "From a Universe of Objects to a Universe of Experiences," and "Physics and the One."Malin also includes three appendices on the relativity of simultaneity, the proof of Bell's inequalities, and interpretations of quantum theory (i.e., quantum ontologies)."e Quandary" examines the debate between Niels Bohr and Albert Einstein regarding the completeness of quantum mechanics.Einstein believed that quantum mechanics violates both local realism and determinism and therefore fails as a complete, fundamental theory of nature while Bohr held that quantum mechanics was complete regardless of its violations.Bohr's radical thesis was that a single model cannot adequately describe the atomic and subatomic realms.His complementarity framework of wave/particle applies to different conditions, but even here Bohr is not describing nature itself, but rather what we can know about nature.Malin distinguishes between Einstein's ontic approach and Bohr's epistemic approach (39).e latter, which became the orthodox "Copenhagen Interpretation," is often described as pragmatic or instrumentalist since quantum theory is to be viewed as merely a set of rules for calculating correlations among observations.As the Einstein-Bohr controversy continued through their disciples, John Bell demonstrated in 1964 that the issue was not merely philosophical but rather scientific when his theorem led to an experiment that proved nature violates local realism.At this round, Bohr wins, Einstein loses.Malin understands "the quandary" to be the fact that local realism must be abandoned even if it is the "eminently reasonable" world-view to which we continue to cling.Physics (post Bell's theorem) has suffered a type of "schizophrenia" since physicists adhere to Bohr's view as the orthodox interpretation of quantum mechanics, yet, at the same time, rely on Einstein's paradigm at some fundamental level.Malin's
