The idea of human rights is also closely related to that of natural rights: some acknowledge no difference between the two, regarding them as synonymous, while others choose to keep the terms separate to eliminate association with some features traditionally associated with natural rights.[2] Natural rights, in particular, are considered beyond the authority of any government or international body to dismiss. The 1948 United Nations Universal Declaration of Human Rights is an important legal instrument enshrining one conception of natural rights into international soft law. Natural rights were traditionally viewed as exclusively negative rights,[3] whereas human rights also comprise positive rights.[4] Even on a natural rights conception of human rights, the two terms may not be synonymous.
