  • Still other philosophers have suggested that both the nonidentity problem and the repugnant conclusion can be avoided by principles that require agents to create additional wellbeing “for persons” (even if not for particular persons) but restrict that obligation to the case where they can substitute in a single, better off, nonidentical child in place of the less well off child.

  • The success of this take on the nonidentity problem will depend in part on whether we can plausibly account for an act's being wrong in cases in which it is clear to us that the act both really is wrong and not worse for any person who does or will exist.

    The Nonidentity Problem Roberts, Melinda 2009

  • This view bifurcates the nonidentity cases, by suggesting one analysis of wrongful life case and another of, e.g., the depletion case: the future persons will all be deemed to have suffered harm but only the victims of depletion will be deemed to have been harmed by the choice under scrutiny.

    The Nonidentity Problem Roberts, Melinda 2009

  • A contractualist approach to the nonidentity problem will focus on the legitimate expectations future persons have in respect of the agents whose acts cause them both to exist and suffer.

    The Nonidentity Problem Roberts, Melinda 2009

  • These concerns seem rooted in the hope that the nonidentity problem can be addressed within the scope of a person-affecting approach without taking the extreme step of denying that the acts under scrutiny in the nonidentity cases are wrong.
