 Approaches to justification include grounding human rights in prudential reasons, practical reasons, moral rights (Thomson 1990), human well-being (Sumner 1987, Talbott 2010), fundamental interests (Beitz 2015), human needs (Miller 2012), agency and autonomy (Gewirth 1996, Griffin 2008) dignity (Gilabert 2018, Kateb 2011, Tasioulas 2015), fairness (Nickel 2007), equality, and positive freedom (Gould 2004, Nussbaum 2000, Sen 2004). Justifications can be based on just one of these types of reasons or they can be eclectic and appeal to several (Tasioulas. 2015).
