Philosophy of law is a multifaceted science that arose and is developing at the intersection of philosophy and jurisprudence. Therefore, it presupposes not only a deep comprehension of these sciences, but also a creative combination of them with each other with the goal of the most complete knowledge of the phenomenon of law. In the work “Philosophy of Law” B.N. Chicherin largely reproduces the Hegelian approach to law as the development of the idea of freedom, the realization of free will.
