    It is not the case that Dreamless sleep is a recognized discontinuity of the same type as deep anesthesia, and both are bracketed by Parfit as cases where the criterion applies diachronically across waking episodes, not synchronically through each instant.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Dreamless sleep involves brain activity and implicit memory encoding, unlike anesthesia, making them categorically different discontinuities.
      ?

      Think about whether this reason is strong or weak

    • 2.Diachronic criteria require identity-constituting relations between episodes, but temporal gaps create inferential gaps in what grounds identity.
      ?

      Think about whether this reason is strong or weak

    • 3.If discontinuity is 'recognized' as such, we need positive evidence that identity *can* traverse it, not just that synchronic criteria fail.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Personal identity persists through gaps in consciousness if psychological continuity connects pre- and post-gap mental states.
      ?

      Think about whether this reason is strong or weak

    • 2.Dreamless sleep and anesthesia share the feature of interrupting consciousness while preserving causal chains of memory and intention.
      ?

      Think about whether this reason is strong or weak

    • 3.Synchronic criteria (unity within moments) cannot account for survival through any sleep, so diachronic criteria are necessary and sufficient.
      ?

      Think about whether this reason is strong or weak
