  Clearly, though, if it is identity alone that renders a future experiencer's experiences mine, then the view runs into difficulty when, once more, we consider the possibility of fission. If I undergo fission, then, given the standard arguments, I will not survive (setting four-dimensionalist considerations aside). Nevertheless, surely we want to say that I still have a valuable future – indeed, it is overwhelmingly plausible to say I will have  two valuable futures. This only makes sense, though, if we prize apart the having of a valuable future from the obtaining of the (numerical) identity relation (for resistance to this point, see Heathwood 2011). If we do so, though, we are insisting that the relations that matter in the having of a valuable future are definitely psychological, in which case, even if I am identical with some past fetus (qua organism or animal), that is irrelevant: what matters in the having of a valuable future does not obtain between us, so while a fetus has a future, it really does not have a future like ours.
