    A 'world' must be a temporally extended structure, making reidentification over time a necessary condition for defining worlds.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.A 'world' should be a temporally extended structure.
      ?

      Think about whether this reason is strong or weak

    • 2.Reidentification over time is required for any temporally extended structure to count as a world.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.David Lewis's modal realism treats possible worlds as spatiotemporally isolated wholes, where intra-world identity tracks counterpart relations, not strict reidentification.
      ?

      Think about whether this reason is strong or weak

    • 2.If counterpart theory suffices for modal predication without strict reidentification, temporal extension alone cannot ground world-individuation via reidentification conditions.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Barbour's 'timeless' interpretation of quantum gravity treats the universe as a static configuration space where time is emergent, not fundamental.
      ?

      Think about whether this reason is strong or weak

    • 2.If a coherent physical world-description requires no primitive temporal extension, then reidentification over time is a derived convenience, not a necessary condition for world-hood.

    A justification for this identification can be variously given by suggesting that a ‘world’ should be a temporally extended structure and thus reidentification over time will be a necessary condition for defining worlds; or similarly by suggesting that in order for observers to have evolved there must be stable records of past events (Saunders 1993, and the unpublished Gell-Mann and Hartle 1994 – see the Other Internet Resources section below); or that observers must be able to access robust s
