 Wayne (2002) has suggested that quantum field theory is best interpreted as postulating extensive holism or nonseparability. On this interpretation, the fundamental quantities in quantum field theory are vacuum expectation values of products of field operators defined at various spacetime points. The field can be reconstructed out of all of these. Nonseparability supposedly arises because the vacuum expectation value of a product of field operators defined at an n-tuple of distinct spacetime points does not supervene on qualitative intrinsic physical properties defined at those n points, together with the spatiotemporal relations among the points. But it is not clear that vacuum expectation values of products of field operators defined at n-tuples of distinct spacetime points represent either qualitative intrinsic physical properties of these n-tuples or physical relations between them. Improved assessment of the extent to which quantum field theory illustrates  holism  or  nonseparability  must await further progress in the interpretation of quantum field theory. (Kuhlman, Lyre and Wayne (2002) represents a relevant first step: but see also Fraser (2008), Baker (2009).)
