    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Strong global supervenience holds that every B-preserving isomorphism between two worlds must itself be A-preserving.
      ?

      Think about whether this reason is strong or weak

    • 2.If every B-preserving isomorphism between two worlds must be A-preserving, then if any B-preserving isomorphisms exist between two worlds, at least one of them must be A-preserving.
      ?

      Think about whether this reason is strong or weak

    • 3.The condition that at least one B-preserving isomorphism is A-preserving is exactly the condition required by intermediate global supervenience.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.The entailment assumes isomorphisms between worlds are total and structure-preserving across all individuals, but worlds may lack a common domain of individuals.
      ?

      Think about whether this reason is strong or weak

    • 2.Without a shared domain, 'B-preserving isomorphism' is undefined, so strong global supervenience's quantification over isomorphisms has no object to transmit A-preservation from.
      ?

      Think about whether this reason is strong or weak

    • 3.If the antecedent of strong global supervenience is vacuously satisfied due to domain mismatch, intermediate global supervenience can still fail for worlds with non-overlapping individuals.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Intermediate global supervenience requires that if worlds are B-indiscernible, some B-preserving map between them is also A-preserving, but this is a weaker existential claim about maps, not a universal one.
      ?

      Think about whether this reason is strong or weak

    • 2.Strong global supervenience's universal quantification over isomorphisms entails intermediate's existential claim only if at least one isomorphism exists, yet worlds with radically different cardinalities may share B-profiles with no isomorphism available.
      ?

      Think about whether this reason is strong or weak

    • 3.Kim's own formulations in 'Supervenience and Mind' leave the existence of inter-world isomorphisms as a substantive metaphysical assumption, not a logical guarantee, breaking the entailment.
      ?

      Think about whether this reason is strong or weak

    It is also easy to see that strong individual supervenience entails strong global supervenience. Suppose that A-properties fail to strongly globally supervene on B-properties. That means that there are two worlds w1 and w2 between which there is a B-preserving isomorphism that fails to be A-preserving. So, for some x in w1, the image of x under I in w2—call it y—has all and only the same B-properties as x in w1, but differs from x in w1 in at least one of its A-properties. But that is just to sa
