    It is not the case that Adam (the original embryo) does not survive twinning as either or both twins.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.An entity can survive fission by being fully identical with each of its successors, as Parfit argues in 'Reasons and Persons' (1984).
      ?

      Think about whether this reason is strong or weak

    • 2.The non-arbitrariness requirement in P2 is met if both twins equally satisfy the survival relation, making Adam's survival a case of branching rather than cessation.
      ?

      Think about whether this reason is strong or weak

    • 3.The impossibility invoked in P1 conflates numerical identity with the persistence of what matters in survival, which Parfit argues are distinct concerns.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.The four-dimensionalist framework of Lewis and Sider allows that Adam is a temporal stage shared by two distinct person-worms that overlap at the pre-twinning segment.
      ?

      Think about whether this reason is strong or weak

    • 2.On this view, Adam does not cease to exist but is retrospectively identified as the shared initial stage of two persisting four-dimensional entities, preserving a meaningful sense of survival.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.If Adam survived as both twins, there would be one human being living two distinct individual lives, which is impossible since the twins are clearly two separate human beings.
      ?

      Think about whether this reason is strong or weak

    • 2.If Adam survived as only one twin, there would need to be a non-arbitrary reason to identify Adam with one twin rather than the other, but both twins are qualitatively identical to Adam, so no such reason exists.
      ?

      Think about whether this reason is strong or weak

    • 3.The only remaining option is that Adam does not survive twinning.
      ?

      Think about whether this reason is strong or weak
