 Other analyses of what rights do for rightholders are varied. Scanlon (2003, 2013) defends the position that rights are constraints on the discretion of individuals or institutions to act. Sreenivasan (2005, 2010) puts forward a “hybrid” analysis of the claim-right that grafts the interest theory onto the will theory: here the function of the claim-right is to endow the right-holder with the amount of control over another’s duty that advances her interests. Wenar (2005) abandons the idea that all rights have any single function, and sets out a “several functions” theory on which rights perform six distinct functions. Wenar (2013b) then sets out a “kind desire” theory of claim-rights, which turns on what role-bearers like journalists and parents want as such, and more generally on what beings (like humans) want qua the kinds of beings that they are.
