    Postulating that the properties a subsystem has as a separated system are identical to the properties it has as a subsystem of composite systems leads to inconsistency.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Kochen-Specker theorems demonstrate that no hidden-variable theory can assign definite values to all quantum observables simultaneously without contradiction.
      ?

      Think about whether this reason is strong or weak

    • 2.If separated subsystem properties must mirror composite-system properties across all observables, this constitutes precisely the kind of global value assignment Kochen-Specker prohibits.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore the identity postulate for subsystem properties generates the same contradictions Kochen-Specker proofs establish for hidden-variable completeness.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.Holism about quantum systems, defended by Teller (1986) and Howard (1989), entails that entangled composites possess non-supervenient relational properties irreducible to their parts.
      ?

      Think about whether this reason is strong or weak

    • 2.If subsystem properties in isolation were identical to their properties within entangled composites, quantum holism would be trivially false, contradicting well-established interpretive results.
      ?

      Think about whether this reason is strong or weak

    • 3.The identity postulate thus presupposes a separability condition that quantum mechanics itself, under any serious interpretation, systematically violates.
      ?

      Think about whether this reason is strong or weak

    Reason against
    ?
    • 1.Bacciagaluppi (1995) and Clifton (1996a) showed that such property assignment is subject to a Kochen-Specker-type contradiction.
      ?

      Think about whether this reason is strong or weak

    • 2.A Kochen-Specker-type contradiction entails logical inconsistency in the property assignment.
      ?

      Think about whether this reason is strong or weak

    The failure of property composition in the modal interpretation calls for explanation. It may be tempting to postulate that the properties that a system (e.g. the L-particle) has, as a separated system, are the same as the properties that it has as a subsystem of composite systems. But, as Bacciagaluppi (1995) and Clifton (1996a) have shown, such property assignment will be inconsistent: It will be subject to a Kochen and Specker-type contradiction. Furthermore, as Vermaas (1997) demonstrates, t
