This paper defends the explanatory priority for the general descriptive theory of law of an investigation into law’s normative point over an investigation of law’s other central features. The paper begins by clarifying the normative priority thesis and implications of the assertion that law has a normative point. It then develops, in Section II, two arguments in favour of the priority thesis. Section III demonstrates the explanatory power of the law’s normative point priority thesis by reference to the related, but derivative, problem of the normativity of legal directives.
