CONTRADICTION IN LOGICAL DOCTRINES OF THE EARLY 20TH CENTURY: INNOVATIVE DEVELOPMENTS OF N. A. VASILIEV AND P. A. FLORENSKY

Abstract

Purpose. The purpose of the study is to determine the role of contradiction in logical and philosophical search by outstanding Russian philosophers and methodologists of the early 20th century - N. A. Vasiliev and P. A. Florensky; to show how the idea of contradictions in being and thinking influenced the choice of logical topics by two famous thinkers of the Silver Age. Methodology and Approach. The methodology of the study includes the method of constructing formulas of the propositional calculus language, the method of graphical representation of the relationships between attributive judgments and the judgments of imaginary logic in the form of a logical square and a triangle of opposites of imaginary logic, a comparative historical method based on the analysis of sources on the history of logic. Results. It was concluded that the starting point for the creation of non-classical paraconsistent teachings was a desire to overcome the contradictions in knowledge, on the one hand, and to substantiate theological provisions, on the other. Moreover, the author considers not only similarities, but also differences in the philosophical constructions of N. Vasiliev and P. Florensky. Theoretical and / or Practical Implications. The theoretical significance of the study lies in the fact that it sheds light on the history of the Russian school of logic.
