Abstract

Your replica is created on Mars and you, on Earth, are destroyed. Parfit claims that your replica may still have what prudentially matters for you – provided that you are psychologically connected and continuous with your replica. If someone accidentally destroys the tapes containing your psychological profile used in the production of your replica and this same action fortuitously produces a functionally equivalent tape, Ehring claims that Parfit should maintain that the resulting new individual may still have what matters. Nihilism about what matters follows, or so Ehring claims. I argue that Ehring is wrong and that the difference between the two ways of creating a replica is not trivial – there is no trivial survival.
