  A final methodological view, which deserves separate treatment both because of its influence and sophistication, is Dworkin’s (Dworkin 1986). This view takes it that (i) the target of a first-order theory of law is existing legal practice and (ii) these theories succeed to the extent that they offer a defensible constructive interpretation (in Dworkin’s sense) of that practice. According to the constructive interpretation view, the aim of a first-order theory of law is not to analyze any concept or to reduce legal facts to other more foundational facts. Rather, the aim of a legal theory is to reconstruct the behavior and self-understandings of participants in legal practice and, moreover, to do so in a way that casts this practice in its best moral light. As a result, a theory of law is more successful the better it both fits with the data about how legal practitioners understand the practice they are engaged in, while also normatively justifying that practice (Dworkin 1986; Perry 1995, 129–31; see also the entry  on  legal interpretivism).
