    It is not the case that Kripke's own essentialist arguments in 'Naming and Necessity' ground necessity in identity conditions that presuppose uniqueness of the kind's extension.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Kinds can have indeterminate or vague boundaries yet still possess genuine modal properties and fixed identity conditions.
      ?

      Think about whether this reason is strong or weak

    • 2.The argument conflates epistemological access to extension with metaphysical requirements for identity; necessity doesn't require uniqueness.
      ?

      Think about whether this reason is strong or weak

    • 3.Historical counterexamples show kinds (gold, water) have been reclassified while maintaining identity; extension uniqueness is too restrictive.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Kripke's rigid designators require stable reference across possible worlds, which demands determinate identity conditions for kinds.
      ?

      Think about whether this reason is strong or weak

    • 2.Natural kind essentialism requires extension uniqueness; otherwise multiple distinct kinds could satisfy identical origin/composition properties.
      ?

      Think about whether this reason is strong or weak

    • 3.If kinds lacked unique extensions, their modal properties would be indeterminate, making necessary truths about them unknowable.
      ?

      Think about whether this reason is strong or weak
