  On conceptual analysis views, theories of law aim to capture the concept of law and they succeed to the extent that they provide a coherent account of the relevant data about that concept and related concepts. In particular, the data to be systematized are taken to be people’s intuitions involving some shared concept of law (or cognate concepts like legal validity or legal obligation). In their simplest form, such intuitions can be thought of as judgments about whether the relevant concept does or does not apply to particular cases. Accordingly, on this sort of view, a theory of law aims to provide an account of the conditions under which the target concept of law (or one of its cognates) applies.
