In the theoretical — methodological considerations of the study of, law in the sixties and seventies an important part was played by the studies on the specific traits and mutual relations of particular legal disciplines, as well as on the relations of the study of law to non-legal disciplines, mainly to philosophy and social sciences. Inquiries on these problems were undertaken both in the Western and in the Socialist science, not only in numerous individual scientific enterprises, but also in collective works, initiated by specially programmed conferences and symposia, having many a time an international range. The number of such works is so considerable that it would not be easy to give an exhaustive list of them.¹
