    Supports→Carter's argument against the claim that S and S' are identical fails

    Reasons For

    1 perspective
    Reason for
    ?
    • 1.Carter assumes identity has a determinate fact-of-the-matter before examining whether competing candidates (original wood, continuous function) satisfy it.
      ?

      Think about whether this reason is strong or weak

    • 2.Circular reasoning occurs when one presupposes the conclusion needed to evaluate premises. Carter does exactly this with ship identity.
      ?

      Think about whether this reason is strong or weak

    • 3.A non-circular approach would first establish criteria for identity, then apply them neutrally to competing candidates.
      ?

      Think about whether this reason is strong or weak

    Reasons Against

    1 perspective
    Reason against
    ?
    • 1.Carter may be arguing conditionally: 'IF identity requires continuity of matter, THEN the original ship survives,' avoiding petitio principii.
      ?

      Think about whether this reason is strong or weak

    • 2.Evaluating competing candidates necessarily requires background assumptions about what matters for identity—this is not circular but foundational.
      ?

      Think about whether this reason is strong or weak

    • 3.The charge of petitio principii requires showing Carter's conclusion appears in his premises; merely having background assumptions is insufficient.
      ?

      Think about whether this reason is strong or weak
