    Supervaluationism is a respected theory of vagueness because indecision about meaning can be both intentional and functional.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Expressivists can explain how supervaluationism developed into the most respected theory of vagueness.
      ?

      Think about whether this reason is strong or weak

    • 2.Supervaluationists hold that speakers fill in meanings as they go along in light of new information and interests, rather than committing prematurely.
      ?

      Think about whether this reason is strong or weak

    • 3.This intentional indecision is a functional feature of language use, not a defect.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Supervaluationism collapses under the 'higher-order vagueness' problem: the meta-language used to define 'precisifications' is itself vague.
      ?

      Think about whether this reason is strong or weak

    • 2.If the boundary between admissible and inadmissible precisifications is vague, supervaluationism generates the very indeterminacy it purports to resolve.
      ?

      Think about whether this reason is strong or weak

    • 3.Williamson (1994) demonstrated that this regress cannot be halted without positing sharp boundaries the theory was designed to avoid.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Supervaluationism violates classical inference rules: under supervaluational semantics, 'A or not-A' can be supertrue while neither 'A' nor 'not-A' is true.
      ?

      Think about whether this reason is strong or weak

    • 2.Fine (1975) acknowledged this failure of truth-functionality means standard natural deduction, including argument-by-cases, becomes invalid.
      ?

      Think about whether this reason is strong or weak

    • 3.A semantic theory that abandons core logical inference rules sacrifices too much explanatory machinery to count as functionally superior to its rivals.

    The expressivist is poised to explain how supervaluationism developed into the most respected theory of vagueness. Frege portrayed vagueness as negligent under-definition: One haphazardly introduces a necessary condition here, a sufficient condition there, but fails to supply a condition that is both necessary and sufficient. Supervaluationists counter that indecision can be both intentional and functional. Instead of committing ourselves prematurely, we fill in meanings as we go along in light
