    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Two expressions differ in sense if a rational, reflective agent can assent to a sentence containing one while withholding assent from the corresponding sentence containing the other.
      ?

      Think about whether this reason is strong or weak

    • 2.Lois Lane is a rational, reflective agent who believes the sentence containing 'Superman' to be true while withholding assent from the corresponding sentence containing 'Clark Kent'.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, 'Superman' and 'Clark Kent' differ in sense.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    2 perspectives
    Reason against 1 of 2
    ?
    • 1.Names are rigid designators that directly refer to objects without the mediation of descriptive senses (Kripke, Naming and Necessity).
      ?

      Think about whether this reason is strong or weak

    • 2.Apparent cognitive differences between 'Superman' and 'Clark Kent' reflect ignorance about identity, not distinct semantic senses attached to the names.
      ?

      Think about whether this reason is strong or weak

    • 3.Therefore, the epistemic gap Lois Lane exhibits is a fact about her beliefs, not a feature of the names' meanings.
      ?

      Think about whether this reason is strong or weak

    Reason against 2 of 2
    ?
    • 1.Frege's criterion of sense-difference conflates the semantic content of an expression with a speaker's psychological mode of presentation (Salmon, Frege's Puzzle).
      ?

      Think about whether this reason is strong or weak

    • 2.If substitution failures in propositional attitude contexts tracked genuine sense-differences, we would be forced to individuate senses so finely as to make communication across believers impossible.
      ?

      Think about whether this reason is strong or weak

    • 3.A more parsimonious account holds that 'Superman' and 'Clark Kent' share a single semantic value while pragmatic or psychological factors explain substitution failures.
      ?

      Think about whether this reason is strong or weak

    This version of the criterion has Frege’s formulation as a special case, since sentences are, of course, expressions; and it solves the problem with obvious truths, since it seems that substitution of sentences of this sort can change the truth value of a propositional attitude ascription. Furthermore, the criterion delivers the wanted result that coreferential names like “Superman” and “Clark Kent” differ in sense, since a rational, reflective agent like Lois Lane could think that (17) is tru
