On the origins of integrative legal thinking in the works of P.A. Sorokin, A.S. Yashchenko, and P.G. Vinogradov

The paper deals with an integrative (synthetic) type of legal thinking in the pre-revolutionary theory of law and philosophy of law. The author examines the ideas of P.A. Sorokin, A.S. Yashchenko, and P.G. Vinogradov, the outstanding Russian legal scientists of the pre- revolutionary period, about the law as a special normative symbolic and institutional system, which is an integral part of the common system of social regulation. The research shows the main ways to overcome the extremes of traditional approaches to law (natural law, positivist, sociological ones) as represented in the works of these thinkers. The author concludes that it is important to develop the ideas about the system-based law in modern Russian society, include a set of natural laws, standards of customary law and legal thinking along with legislation in the sources of law, and update state legal institutions during social reforms.
