   A second seemingly uncontroversial way in which legal theory is evaluative is that one cannot begin to develop a theory of law without determining which of its central features are to be accounted for (Dickson 2001, 38–45). John Finnis, for example, argues that one cannot do first-order legal theory without taking a stand on what the important features of law are that adequate theories must explain (e.g., the law’s claim to authority). However, this seems to require evaluation (Finnis 1980, 9–15).
