 Should human rights be defined in terms of serving some sort of political function? Instead of seeing human rights as grounded in some sort of independently existing moral reality, a theorist might see them as the norms of a highly useful political practice that humans have constructed or evolved. Such a view would see the idea of human rights as playing various political roles at the national and international levels and as serving thereby to protect urgent human and national interests. These political roles might include providing standards for international evaluations of how governments treat their people and specifying when use of economic sanctions or military intervention is permissible (see  Section 2.3 Political Conceptions of Human Rights  below).
