According to various “harm-based” approaches to the non-identity problem, an action that brings a particular child into existence can also harm that child, even if his or her life is worth living. In the third chapter of The Non-Identity Problem and the Ethics of Future People, David Boonin surveys a variety of harm-based approaches and argues that none of them are successful. In this paper I argue that his objections to these various approaches do not impugn a harm-based approach that Boonin does not consider, an approach I call the “existence solution to the non-identity problem.” I also argue that the existence solution is more plausible than Boonin’s own proposed solution
