A collection of thought-provoking essays by philosopher-physicists, all of whom find themselves wrestling with the consequences of what appear to be empirical violations of local realism. Contained within their musings on this profound demonstration of experimental metaphysics are sometimes provocative interpretations and suggestions ranging from a universal holism intrinsic to nature, superluminal causal influences, the impossibility of assigning definite physical states to unobserved systems, A collection of thought-provoking essays by philosopher-physicists, all of whom find themselves wrestling with the consequences of what appear to be empirical violations of local realism. Contained within their musings on this profound demonstration of experimental metaphysics are sometimes provocative interpretations and suggestions ranging from a universal holism intrinsic to nature, superluminal causal influences, the impossibility of assigning definite physical states to unobserved systems, and even potential applications to the mind-body problem (something I find fairly ludicrous). The contributors within possess a remarkable ability to explain physical concepts and their philosophical consequences without recourse to the abstract reifications of popular science. Despite its age, it is an insightful collection of lucid essays on the metaphysical implications of Bell's Theorem and those interested in the philosophy of physics should not miss it.
