First, a theory of justice needs to explain on what basis it justifies its principles or claims of justice. For example, while the early Nussbaum (1992) justifies her list of capabilities through an analysis of what can be considered essential human traits, the later Nussbaum (2011a) holds that her list of capabilities is justified because they promote human dignity. Anderson (1999, 316) argues that people should be entitled “to whatever capabilities are necessary to enable them to avoid or escape entanglement in oppressive social relationships” and “to the capabilities necessary for functioning as an equal citizen in a democratic state.” Claassen (2017, 2018) argues that the capabilities relevant for social justice can be derived from society’s ultimate concern with navigational agency.
