The validity of demonstrably wrong law cannot conceivably be justified. However, any answer to the question of the purpose of law other than by enumerating the manifold partisan views about it has proved impossible- and it is precisely on that impossibility of any natural law, and on that alone, that the validity of positive law may be founded. At this point relativism, so far only the method of our approach, enters our system as a structural element.
Ordering their living together cannot be left to the legal notions of the individuals who live together, since these different human beings will possibly issue contradictory directions. Rather, it must be uniformly governed by a transindividual authority. Since, however, in the relativistic view of reason and science are unable to fulfill that task, will and power must undertake it. If no one is able to determine what is just, somebody must lay down what is to be legal.
