The distinctively legal emerges with the development of secondary rules, that is, rules of authoritative determination. These rules, selectively applied, 'raise up' the primary norms and give them a legal status. . . . The appeal from an asserted rule, however coercively enforced, to a justified rule is the elementary legal act. This presumes at least a dim awareness that some reason lies behind the impulse to conform, a reason founded not in conscience, habit, or fear alone, but in the decision to uphold an authoritative order."
