Balancing legal values, using, among other things, the economic analysis of law, is one of the ways of the conscious evolution of law, its synchronization with the flow of life of society. Another problem is related to the conflict between the natural boundaries of law as a scientific and practical field of knowledge, and the regulatory function of law, which presupposes a timely and adequate response of the law to external events and challenges. The authors turn to Luhmann’s distinction between the normative closeness of law and its cognitive openness and come to the conclusion that there is both direct and indirect communication between law and other normative systems (such as ethics and economics).
