The book of the famous French philosopher, specialist in the problems of the methodology of scientific knowledge, Professor of the University of Lille Noel Mouloud, deals primarily with the semantic foundations of logic and epistemology. The work of prof. Muluda refers to research characterized not only by a general understanding of the importance of fundamental philosophical problems and categories for solving problems of special scientific knowledge, but also by the conscious use of this categorical apparatus in the course of analyzing special scientific problems.
