I think I understand what you mean, but it is a problem of appearances,
not identity. The appearances labeled "Clark Kent" and "Superman"
belong to a single being; Clark Kent is identical to Superman,
in the same sense that the evening star is the morning star, though
they don't have the same appearances (one is in the west, the other
in the east).
