    It is not the case that If 'a > n for every natural number n' can only be verified schema-theoretically and never instancewise, the quantifier range presupposes what it purports to prove.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Schema-theoretic proofs work by formal derivation rules, not by presupposing quantifier ranges—the rules generate the quantifier's legitimacy inductively.
      ?

      Think about whether this reason is strong or weak

    • 2.Instance-wise verification of infinite claims is impossible in principle; rejecting schema-theoretic methods leaves universal quantification meaningless entirely.
      ?

      Think about whether this reason is strong or weak

    • 3.Quantifier ranges in formal systems are defined by axioms (like Peano's), not presupposed; the claim conflates semantic interpretation with logical justification.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Schema-theoretic verification relies on a uniform rule, not exhaustive checking, so it cannot ground claims about infinite totalities without circularity.
      ?

      Think about whether this reason is strong or weak

    • 2.Instance-wise verification of 'a > n' requires checking each n individually; schema-theoretic proof instead presupposes the infinity we're trying to establish.
      ?

      Think about whether this reason is strong or weak

    • 3.Quantifying over 'every natural number' already assumes the totality of naturals exists; using only schema-theoretic methods begs this assumption.
      ?

      Think about whether this reason is strong or weak
