    It is not the case that Psychological continuity admits of degrees, making it unsuitable as a criterion for the all-or-nothing relation of numerical identity.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.All fundamental physical relations (mass, charge, spatiotemporal location) admit of degrees, yet successfully ground determinate identity conditions.
      ?

      Think about whether this reason is strong or weak

    • 2.The all-or-nothing appearance of identity may reflect our linguistic practices, not metaphysical reality; vagueness in criteria doesn't entail vague identity.
      ?

      Think about whether this reason is strong or weak

    • 3.Psychological continuity could determine identity via a threshold: sufficient continuity constitutes identity, just as 'heap' works despite grain vagueness.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Numerical identity is a fundamental logical relation that is determinate: either X is identical to Y or it is not, admitting no middle ground.
      ?

      Think about whether this reason is strong or weak

    • 2.Psychological continuity demonstrably varies by degree across cases (memory chains, personality overlap, intentions), not present uniformly.
      ?

      Think about whether this reason is strong or weak

    • 3.If a criterion for identity permits borderline cases, it fails to capture what identity actually is—a precise metaphysical relation.
      ?

      Think about whether this reason is strong or weak
