Scheme of Lev Vygotsky's Theory. Part 1

The relevance of referring to Lev Vygotsky's works and discovering the unknowable in them is a natural phenomenon that accompanies brilliant works of science, literature, art, etc. Discoveries are accidental and non-accidental at the same time, so they are either accepted immediately or pass the "corridor" of criticism. The history of the formation of Vygotsky's psychology is also the history of our way of understanding Vy-gotsky. The aim of the article is to reveal what Lev Vygotsky himself might not have highlighted. We have tried to penetrate into the logic, the scheme of his thinking. It is possible to carry out the reconstruction in different ways, as evidenced by the experience of the world "vygotskopovedeniya". In this article we argue the hypothesis about the logic of triangulation by L.S. Vygotsky. Triangulation acts as a method of analyzing the psyche with the help of "units of analysis of the whole". In our opinion, L. S. Vygotsky analyzed the psyche as a triangular dynamic network. The network structure allows to reveal new, logically substantiated connections between its elements. He constructed a logical "construct" allowing to confirm it empirically. The basis of the network is formed by trinities of mental functions and connections between trinities, when the same function is included in different trinities. A trinity is formed and in it`s development represents a synthesis of the ele-ments forming it. Each mental function is a whole and reflects in itself a larger whole, i.e., the psyche. It is in the structure of the trinity network that this is most clearly traced. The analysis undertaken by L.S. Vygotsky undoubtedly belongs to the post-nonclassical type of scientific rationality.
