Should we say of the Adam of wn that he is identical with the Noah of w1 and should we say of the Noah of wn that he is identical with the Adam of w1? In other words, is there an x such that x is Adam in w1 and x is Noah in wn, and is there a y such that y is Noah in w1 and y is Adam in wn? And how are we to decide? … aren’t the two Adams, the two Noahs, and the two worlds indiscernible? Could God possibly have had a sufficient reason for creating w1 instead of wn? (3–4)
