    Sign theory (speculative grammar) is more central to Peirce's account of inquiry than previously recognized.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Logic, in Peirce's architectonic system, contains three branches: Speculative Grammar, Critical Logic, and Methodeutic.
      ?

      Think about whether this reason is strong or weak

    • 2.Sign theory corresponds to Speculative Grammar.
      ?

      Think about whether this reason is strong or weak

    • 3.Peirce came to see sign theory as more clearly connected to the logic of scientific discovery (Methodeutic).
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Peirce's own mature architectonic places Methodeutic, not Speculative Grammar, as the culminating branch most directly governing inquiry's conduct.
      ?

      Think about whether this reason is strong or weak

    • 2.Speculative Grammar merely classifies sign types without prescribing inferential norms, making it a prolegomenon to logic rather than its operative core.
      ?

      Think about whether this reason is strong or weak

    • 3.W.B. Gallie and subsequent pragmatism scholars have argued that Peirce's theory of inquiry is fundamentally driven by his normative account of abduction, which belongs to Critical Logic, not sign theory.

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.The historical record shows Peirce repeatedly subordinated semiotic to his phenomenological categories, suggesting sign theory inherits its structure from phaneroscopy rather than generating it.
      ?

      Think about whether this reason is strong or weak

    • 2.If sign theory's centrality to inquiry depends on its connection to Methodeutic, the argument proves only that Speculative Grammar is instrumentally useful, not architectonically foundational.

    During the last part of his life the majority of Peirce’s philosophical output concerned semiotic, and he developed his account of signs far beyond the 1903 theory. There seem to be two reasons for this. First, Peirce was geographically and intellectually isolated and his main outlet was correspondence with the English woman, Lady Victoria Welby. Welby wrote on various philosophical topics and shared Peirce’s interests in signs and meaning. This seems to have given Peirce a willing and sympathet
