 A second form of the priority pluralist’s “fundamental relation” move posits only binary entanglement relations, but allows these to hold between individual particles and whole composite systems. Thus Calosi (2014) shows that one can treat e.g., a fully entangled three particle system by positing a binary entanglement relation between the first particle and the composite system made up of the second and third particles. This is problematic insofar as it posits fundamental entanglement relations relating entities that (by the lights of the pluralist) are nonfundamental. How can the fundamental level “see” the composite system made up of particles 1 and 2, in order to put that composite system in fundamental relation to particle 3, if the only individuals found at the fundamental level are noncomposite?
