    It is not the case that If mereological composition is either universally permissive or universally restricted, van Inwagen's 'life' criterion smuggles in biological essentialism without metaphysical justification.

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

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Van Inwagen's criterion isn't biological essentialism; it's a principled constraint on what counts as a genuine 'unified object' versus mere aggregates.
      ?

      Think about whether this reason is strong or weak

    • 2.Many metaphysical views (mereological nihilism, four-dimensionalism) also reject universal permissiveness without invoking biology—undermining the charge.
      ?

      Think about whether this reason is strong or weak

    • 3.Life plausibly tracks functional integration and causal closure in ways non-living aggregates lack, providing metaphysical justification independent of essentialism.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Universal permissiveness allows any parts to compose (e.g., my left shoe + distant star), yet van Inwagen restricts composition to living organisms.
      ?

      Think about whether this reason is strong or weak

    • 2.Van Inwagen provides no principled metaphysical reason why 'life' should demarcate composition boundaries rather than, say, 'physical continuity'.
      ?

      Think about whether this reason is strong or weak

    • 3.If composition rules must apply uniformly across all domains, singling out biology without grounding in fundamental metaphysics appears arbitrary.
      ?

      Think about whether this reason is strong or weak
