 Status theories belong to the tradition of natural rights theories. All natural rights theories fix upon features that humans have by their nature, which make respect for certain rights appropriate. The theories differ over precisely which attributes of humans give rise to rights, although non-religious theories tend to fix upon the same sorts of attributes described in more or less metaphysical or moralized terms: free will, rationality, autonomy, or the ability to regulate one’s life in accordance with one’s chosen conception of the good life. Natural rights theorists agree that human reason can grasp the fact that it is appropriate to treat beings with such attributes in certain ways, although they disagree on whether such facts are self-evident.
