 In deciding which specific rights are human rights it is possible to make either too little or too much of international documents such as the Universal Declaration and the European Convention. One makes too little of them by proceeding as if drawing up a list of important rights were a new question, never before addressed, and as if there were no practical wisdom to be found in the choices of rights that went into the historic documents. And one makes too much of them by presuming that those documents tell us everything we need to know about human rights. This approach involves a kind of fundamentalism: it holds that when a right is on the official lists of human rights that settles its status as a human right (“If it’s in the book that’s all I need to know.”) But the process of identifying human rights in the United Nations and elsewhere was a political process with plenty of imperfections. There is little reason to take international diplomats as the most authoritative guides to which human rights there are. Further, even if a treaty’s ratification by most countries can settle the question of whether a certain right is a human right within international law, such a treaty cannot settle its weight. The treaty may suggest that the right is supported by weighty considerations, but it cannot make this so. If an international treaty enacted a right to visit national parks without charge as a human right, the ratification of that treaty would make free access to national parks a human right within international law. But it would not be able to make us believe that the right to visit national parks without charge was sufficiently important to be a real human right (see Luban 2015).
