Zinoviev developed a theory of society based on his own research in the field of logic and the methodology of science, later calling his theory "logical sociology". Zinoviev often argued that logic interested him as a tool for studying society. Zinoviev's sociological theory can be divided into general and particular. The first relates to the whole world, the second to Soviet communism. The main method of knowledge of society is observation. From a methodological point of view, logical sociology as a rigorous scientific theory was based on two rules: first, the refusal to consider any propositions as a priori true; secondly, the need for a precise definition of the meaning of any term, which would eliminate ambiguity and vagueness. From the second rule, emphasized Zinoviev, followed the importance of constructing a consistent language, free from ideological borrowings. In the explication of terms from the set of objects, those that interest the researcher are highlighted, and a new understanding of the object is introduced; although traditional names can be used (society, government, state, etc.). A classic example is the term "communism", which Zinoviev used exclusively to describe the Soviet social system.
