 This is problematic in two respects, the first of which is that it marks an unprecedented departure from more localist pictures. Thus Darby (2012: 14) continues: “[I]t is no longer possible to think of the world as being built up with these relations one component at a time.” The second respect in which this fundamental \(n\)-place relation is problematic is that it makes the fundamental properties and relations at an entangled \(n\)-particle world at least partially distinct from the fundamental properties and relations at an entangled \(n+1\)-particle world (or at any entangled world with any number of particles other than \(n)\). This seems like a loss of unity.
