  In sections 4.2 and 4.3, we shall briefly review the relevant notions of holism and non-separability (for a more comprehensive review, see the entry on holism and nonseparability in physics and Healey 1991). In section 5, we shall discuss the nature of holism and non-separability in the quantum realm as depicted by various quantum theories. Based on this discussion, we shall consider whether the non-local influences in the EPR/B experiment constitute action at a distance.
