 Griffin’s thesis that all human rights are grounded in normative agency is put forward not so much as a description but as a proposal, as the best way of giving human rights unity, coherence, and limits. Unfortunately, accepting and following this proposal is unlikely to yield effective barriers to proliferation or a sharp line between human rights and other moral norms. The main reason is one that Griffin himself recognizes: the “generative capacities” of normative agency are “quite great.” Providing adequate protections of the three components of normative agency (autonomy, freedom, and minimal well-being) will encounter a lot of threats to these values and hence will require lots of rights.
