Based on the text of I. A. Efremov's novel "The Andromeda Nebula" as a thematic index to the world of communist utopia, the author analyzes the most important leitmotifs of utopian literature: from Thomas More and Campanella to Soviet science fiction of the 1960s. The main task of the book is to analyze what were the main positive values ​ ​ of the communist utopia and what it tried to "seduce" for about 450 years of its continuous development.
