 Describing fundamental norms in terms of rights has benefits as well as dangers (Schneider 1986, Ackerly 2013). The language of rights can give precise expression to elaborate structures of freedom and authority. When embodied in particular doctrines, such as in the international human rights documents, the language of rights can express in accessible terms the standards for minimally acceptable treatment that individuals can demand from those with power over them. Rights are also associated with historical movements for greater liberty and equality, so assertions of rights in pursuit of justice can carry a resonance that other appeals lack. Whether these benefits of using rights language overbalance the hazards remains a live question in moral, political, and legal theory.
