MODERN STUDY IN PHILOSOPHICAL LOGIC: WORLDWIDE LEVEL AND RUSSIAN SCIENCE

In this paper, we survey the development of philosophical logic in Russia within the framework of worldwide tendencies. Philosophical logic is an extremely wide area of logical studies, requiring philosophical judgement of the basic concepts, used in modern logic, and the outcomes obtained by means of mathematical logic. However, we need to remark that the term 'philosophical logic' is uncertain and has no uniform use. Even if philosophical logic is represented as a special scientific discipline, it is not possible to define its subject, limits of application, and methods. Therefore we consider the background of different directions in philosophical logic and its connection with philosophy of logic, foundations of logic, and computerization of logic.
