About the book: year / The book “Spiritual Foundations of Society” is divided into two consecutive topics: the first analyzes the most popular social concepts of the 19th–20th centuries: historicism, biologism, psychologism. These idols of social science of the 19th century. created the illusion of the possibility of reducing social life to “natural” fundamental principles that could be described in the language of positive science. The simple but compelling arguments of S. L. Frank reveal the internal contradiction of these attitudes, which vainly strive to bring the highest from the lowest. At the same time, the author introduces, for him, a fundamental distinction between “conciliar” and “public”. Society is not a derivative association of separate individuals, but a primary integrity, in it (and only in it) a person is given as concreteness. By choosing WE or I as the initial principle, philosophers choose the “lie of abstract collectivism” or the “lie of abstract individualism.” Not inferior in the subtlety of analysis to the pillars of existentialism and dialogism, S. L. Frank proves that “I”, “you” and “we” are correlative and “equally primary””.
