    Part of a larger discussion

    Challenges→Propositions expressed by sentences like 'Violet is a child' should have different truth-values with respect to different times, motivating the inclusion of a time index in semantic evaluation.

    Frege and Russell treated propositions as abstract objects with determinate, unchanging truth-values, making temporal indexing a category error.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Mathematical truths like '2+2=4' seem to have fixed truth-values independent of time, suggesting abstract propositions share this timeless character.
      ?

      Think about whether this reason is strong or weak

    • 2.If propositions changed truth-value over time, we couldn't meaningfully compare what someone believed yesterday with what they believe today.
      ?

      Think about whether this reason is strong or weak

    • 3.Temporal operators like 'it will be true that' can be understood as claims about concrete events, not as indexing the proposition itself.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Sentences like 'it is raining' have determinate truth-conditions only relative to a time and place, suggesting propositions are inherently temporal.
      ?

      Think about whether this reason is strong or weak

    • 2.The correspondence theory of truth requires propositions to match reality; since reality changes, propositions must track those changes to remain truthmakers.
      ?

      Think about whether this reason is strong or weak

    • 3.Treating 'propositions are eternal' as dogmatic ignores that most meaningful discourse involves temporal content essential to semantic evaluation.

      Think about whether this reason is strong or weak
