  A deeper worry about all forms of conceptual analysis is the question of why we should care about anybody’s concept of law in the first place (Marmor 2013, 216–217; Leiter 2007, 177–79). After all, as philosophers, it seems that it is the nature of law itself that we care about understanding (Raz 2004, 7, 10). Granted, there are interesting sociological questions to be asked about what various groups of people believe to be the case about how law functions. But it is not obvious that there is anything distinctively philosophical about such questions. Insofar as philosophers (qua philosophers) are interested in what people believe about a given concept, this would be because understanding people’s beliefs about the concept is a route to understanding that which it is a concept of (Raz 2004, 4, 10). Accordingly, one might think that what theories of law aim to capture is not anybody’s concept of law in particular, but rather the nature of law itself.
