    The Wiggins-Parfit paradigm case of multiple personal identity can be represented as follows: if b's left cerebral hemisphere is transplanted1 into another body to make the composite organism b(a), and the right one into another body to make b(b), would not b(a) and b(b) be the same person? But brain-bisected humans show functional independence of the deconnected hemispheres, indicating b is a compound of two hemisphere-based persons to begin with. There is then no need to give up the language of identity, as Parfit has urged, and indeed one can find good reasons why we should not.
