To my mind, it is one of the profound contradictions of human existence that we long for immortality, indeed fervently believe that something must be unchanging and permanent, when all of the evidence in nature argues against us. I certainly have such a longing. Either I am delusional, or nature is incomplete. Either I am being emotional and vain in my wish for eternal life for myself and my daughter (and my wingtips), or there is some realm of immortality that exists outside nature.
