  A third way in which legal theory could in principle be evaluative, though uncontroversially so, is suggested by the prescriptive view discussed in section 2.1.3. If the job of a first-order theory of law is to identify the concept of law it would be most desirable for us to employ, then there is a sense in which the resulting theory of law would of course be evaluative. Nonetheless, as seen above, prescriptive theories aim to answer a different question from theories in the conceptual analysis, reductive or interpretive categories. Thus, what matters to the debate about whether legal theory is evaluative is not whether legal theory in principle could be evaluative, but whether it is inevitably or necessarily so.
