 Some respond to the argument by maintaining that it is indeterminate which of various objects ‘Theseus II’ picks out. If that’s right, then ST2 is arguably false. One cannot infer the existence of an individual who is indeterminately identical to Sue from the fact that it is indeterminate whether Sue (or rather Morgan) is Harry’s best friend. Analogously, one cannot infer the existence of an individual that is indeterminately identical to the mended ship from the fact that it is indeterminate whether Theseus II is the mended  ship.[31]
