  This necessity of value-laden selection of concepts and terms for use in a general theory of social realities such as law is evidenced in the work of Max Weber, prophet of “value-free” social science. His account, for example, of forms of domination (Herrschaft) identifies three pure, central, characteristic types (Idealtypen): charismatic, traditional, and rational (bureaucratic, legal). But the accounts of the first two types are almost entirely in terms of how they differ from the rational type, whose rationality is self-evident to Weber and his readers on the basis of their own knowledge of human goods (basic aspects of human wellbeing) and related practical truths. See Finnis 1985, 170–72. Natural law theory, as one sees it practiced already in Aristotle’s Ethics and Politics, makes these valuations by the theorist overt and explicit (not hidden and embarrassed), and subjects them to rational scrutiny and debate.
