    Two predications with different built-in temporal indices... — Carmelics

    Part of a larger discussion

    Supports→The contradiction used to refute relative identity dissolves if one sortal is treated as a phase sortal and another as an ultimate sortal.

    Two predications with different built-in temporal indices are not univocal contradictories, so the apparent logical contradiction in relative identity cases never arises in the first place.

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Propositions indexed to different times express different temporal contents, so 'is at t1' and 'is at t2' are logically distinct predicates.
      ?

      Think about whether this reason is strong or weak

    • 2.Contradictions require univocal predicates applied to the same subject at the same time; temporal indexing shifts the time reference.
      ?

      Think about whether this reason is strong or weak

    • 3.Relative identity cases (e.g., 'same ship, different statue') succeed when we recognize implicit temporal operators resolving apparent conflicts.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Even with temporal indices, 'the object is F at t1' and 'the object is not-F at t1' are genuine contradictions within that time-slice.
      ?

      Think about whether this reason is strong or weak

    • 2.Temporal indexing alone cannot resolve relative identity paradoxes unless criteria for identity persistence across time are independently specified.
      ?

      Think about whether this reason is strong or weak

    • 3.Adding temporal indices to predicates only defers the logical problem; it doesn't explain why one identity criterion applies over another.
      ?

      Think about whether this reason is strong or weak

    Key Terms

    Logical contradiction(as what the stratified framework avoids)
    When two statements cannot both be true at the same time because they directly oppose each other. For example, 'it is raining' and 'it is not raining' are contradictory.
    contradictories(Preserved intuition in paraconsistent semantics)
    A and B are contradictories iff, if A is true, B is false, and if A is false, B is true.
    predication(Soames treats predication as a primitive notion that underlies but does not reduce to belief.)
    A primitive mental act whereby an agent represents an object as having a property — for example, representing o as red via perception, thought, or nonlinguistic perceptual belief.
    relative identity(The passage argues against the coherence of relative identity using Leibniz's Law.)
    The view that identity can hold relative to a sortal, so that a and b may be the same F but not the same G.
    temporal indices(as used in logic and philosophy of time)
    Built-in time markers that specify when something is true—like saying 'John is tall at age 20' versus 'John is short at age 5,' where the times (age 20 vs. age 5) are the temporal indices.
    univocal(Contrasted with homonymy in Aristotle's predication theory)
    A term applied in the same sense across all its predications.
