 Having reported on skeptical doubts concerning the possibility of future people having rights vis-à-vis currently living people we now turn to an analysis of the relevance of the contingency of future people—the subject that, under the title of the “Non-Identity-Problem” has been at the core of much of the philosophical inquiry into the foundations of intergenerational justice  (§§3–4.4;  see also entry  nonidentity problem).  We will introduce that core issue by addressing a specific criticism of the person-affecting view in the context of intergenerational justice  (§2.2):  Some have argued that a person-affecting view cannot account for the widely held belief that persons have the right not to be brought into existence if the person-to-be would not reach a sufficiently good (or decent) level of well-being.
