K. Marx's deep foresight about the transformation of science into a direct productive force is gradually coming true. Science ceases to be something external to production and is increasingly becoming its theoretical basis. It is clear that in such conditions, the study of science, the laws of its development acquires particular relevance, in connection with which a whole scientific direction is now being formed - the science of science or science. Of increasing interest are the problems of epistemology, in particular, the question of the forms and methods of scientific knowledge. Problems of this kind begin to receive considerable attention in philosophical research.
