Abstract

We first examine Howard's analysis of the Bell factorizability condition in terms of ‘separability’ and ‘locality’ and then consider his claims that the violations of Bell's inequality by the statistical predictions of quantum mechanics should be interpreted in terms of ‘nonseparability’ rather than ‘nonlocality’ and that ‘nonseparability’ implies the failure of spacetime as a principle of individuation for quantum-mechanical systems. We will argue that his argument for the first claim is less than compelling and that any argument for the second claim will be interpretation-dependent and, hence, not generally valid.

Footnotes

Financial support provided by the John J. Reilly Center for Science, Technology and Values and the Zahm Research Travel Fund, University of Notre Dame. Some of this research was conducted while a Visiting Scholar in the History and Philosophy of Science Department, Cambridge University, during the Lent term 1997. This paper is a revised version of a chapter from my dissertation, “Ontological Commitments and Theory Appraisal in the Interpretation of Quantum Mechanics” (Notre Dame, 1998). My thanks to Jim Cushing and Don Howard for many stimulating conversations on these topics.
