    Originating from a particular gamete pair is only a partial essence of a person, not a full essence.

    Reasons For

    2 perspectives
    Reason for 1 of 2
    ?
    • 1.Kripke's essentialism in Naming and Necessity identifies origin as fixing reference without implying origin alone constitutes a complete individual essence.
      ?

      Think about whether this reason is strong or weak

    • 2.A full individual essence requires haecceity—a primitive thisness distinct from any qualitative or causal-historical property, as Plantinga argues in The Nature of Necessity.
      ?

      Think about whether this reason is strong or weak

    • 3.Gametic origin is a necessary but non-sufficient condition precisely because haecceity cannot be reduced to relational-causal facts about biological origin.
      ?

      Think about whether this reason is strong or weak

    Reason for 2 of 2
    ?
    • 1.The monozygotic twin case demonstrates that biological origin individuates a kind of person-stage, not a numerically unique person, vindicating the partial-essence reading.
      ?

      Think about whether this reason is strong or weak

    • 2.Parfit's reductionism in Reasons and Persons entails personal identity supervenes on physical and psychological continuity, making gametic origin merely one contributor among several individuating factors.
      ?

      Think about whether this reason is strong or weak

    • 3.A partial essence contributes necessary conditions to individuation without exhausting them, which is fully coherent on any multi-factor account of personal identity.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.A full essence must be both necessary and sufficient for being the individual in question.
      ?

      Think about whether this reason is strong or weak

    • 2.A monozygotic twin originates from the same gamete pair as the person yet is a numerically distinct individual.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, originating from a particular gamete pair is not sufficient to identify a unique individual.
      ?

      Think about whether this reason is strong or weak

    It is natural to use the expression ‘the essence of …’, which implies sufficiency as well as necessity: possession of the essence of K suffices for membership of K, as well as being necessary for it. According to the foregoing, not all the arguments of Kripke and Putnam establish what the essence of some kind is, rather they establish only what we may call a partial essence, conditions that are necessary but not sufficient. This is clear in some other of Kripke’s arguments. Thus it is only a par
