 (For a related contemporary view, see Harris 1979: 84–106.) They think that analysing laws this way reveals what legislators or subjects most need to know: under what conditions the coercive power of law will ultimately be met. Others argue that even if such a reduction were possible, it would be unwieldy, uninformative and unmotivated, concealing as it does the different social functions that laws fulfil (Hart 1961 [1994: 26–49]) and the different kinds of reasons for action that they create (Raz 1975 [1990]). Others still, despairing of any principled way of knowing what a law is, have abandoned the problem entirely and tried to develop a theory of law that bypasses it (Honoré 1977; Dworkin 1978: 71–78). At a minimum, it does seem clear that whether or not all laws impose obligations, they can only be fully understood through their relations to those that do. Thus, a legal right is an interest that warrants holding others under an obligation to protect it, a legal power is the ability to create or modify obligations, and so forth.
