post-non-classical rationality

Introduction. The article deals with the role of methodological pluralism in the development of the communicative theory of law. The specificity of modern post-non-classical rationality determines the growth of interdisciplinary research, making new demands on the philosophy of law. In this connection, there is a question of the implementation of the principle of methodological pluralism in the communicative legal understanding. Theoretical analysis. The author examines the deductive monometological character of classical types of legal understanding, shows the barriers that block methodological pluralism. The communicative theory of law is interpreted as a post-non-classical scientific theory based on an open polylogue with various social theories and focused on the search for an integrative legal understanding. Empirical analysis. The author shows the work of the principle of methodological pluralism in the theory of communication as a key source of the communicative theory of law. The researcher analyzes the strategy of detailing the basic categorical series of communication theory by its disciplinary areas, including the communicative theory of law. Results. The author has established the methods of theoretical communication of interdisciplinary fields in the communicative theory of law, the prospects for applying the principle of methodological pluralism in the communicative theory of law, its heuristic potential for answering questions about who creates law, what tools ones uses and what consequences for the social system it leads to.
