    It is not the case that Without distinguishing these co-present selves, endurantism cannot coherently represent the causal structure of the time traveler's personal history, as Lewis's 1976 analysis requires.

    ?Set your confidence on the premises below to see your aggregate.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Perdurantism (not endurantism) better handles time travel; endurantists can simply deny backwards causation rather than multiply selves.
      ?

      Think about whether this reason is strong or weak

    • 2.Co-present selves aren't required—temporal indexing alone (being F-at-t1 vs F-at-t2) preserves causal distinctions within standard endurantism.
      ?

      Think about whether this reason is strong or weak

    • 3.Lewis's own counterpart theory already provides causal structure without metaphysically distinct co-present selves in the same world.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Endurantism claims objects persist by being wholly present at each time; time travelers create temporal loops requiring distinct causally-efficacious stages.
      ?

      Think about whether this reason is strong or weak

    • 2.Lewis's analysis demands tracking which stages cause which effects; without distinguishing co-present selves, causal order becomes indeterminate.
      ?

      Think about whether this reason is strong or weak

    • 3.A single unified enduring self cannot simultaneously be both cause and effect in the same causal chain without violating standard causal asymmetry.
      ?

      Think about whether this reason is strong or weak
