    It is not the case that ΔS4 must therefore either beg the question by encoding modal facts as primitive sort axioms, or fail to derive all S4-valid sequents under the proposed embedding.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Sort-theoretic embeddings can encode modal properties through structural constraints on domains without treating modality as primitive.
      ?

      Think about whether this reason is strong or weak

    • 2.Completeness may be achieved by deriving S4-valid sequents via logical rules applied to sort-structure, not requiring explicit modal axioms.
      ?

      Think about whether this reason is strong or weak

    • 3.The disjunction ignores hybrid approaches where modal content emerges from interaction of logical rules and domain structure systematically.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Modal axioms like T and 4 encode facts about accessibility relations that cannot be derived from non-modal logical resources alone.
      ?

      Think about whether this reason is strong or weak

    • 2.Any embedding that claims completeness without explicit modal axioms must smuggle modal content into supposedly neutral sort-theoretic apparatus.
      ?

      Think about whether this reason is strong or weak

    • 3.The dilemma is genuine: either modal facts are primitive (begging the question) or the embedding is incomplete for S4-validity.
      ?

      Think about whether this reason is strong or weak
