 A second worry for Geach is that it seems as if the relative identity theory cannot solve all of the puzzles with which we began. Take, once again, the Ship of Theseus Puzzle. In that case, we have the original ship of Theseus (A), the museum’s ship (B), and the custodian’s ship (C). The problem is that B seems to be the same ship as A, which seems to be the same ship as C. If the same ship as relation is transitive, we get the absurd conclusion that B is the same ship as C. The relative identity theorist might deny transitivity, of course, but this would give us another reason to suspect that relativized identity relations are not really identity relations at all (Gupta 1980).
