Computational sociology is a subfield of social philosophy that views social relations in the context of comparing them to a computer. «Computational Leviathan» is a concept of computational sociology that draws an analogy between society and social relations and a set of organs of a giant animal in constant interaction. The interaction consists of information exchange, production and consumption of resources, and other mutually beneficial processes. Like organs in an organism, the components of the “computational Leviathan” cannot do without each other, being in mutual dependence. The cessation or disruption of one of the components immediately affects the activity of the others, which, in turn, leads to fundamental changes in the functioning of the “Leviathan” or to death, i.e. to the end of human civilization. The purpose of this article is to reveal the role of the individual in the concept of “computational Leviathan.” Research methods: theoretical: information analysis, synthesis of judgments and observations, analogy; modeling; empirical: comparison, cross-sectional study, text analysis, method of expert evaluations. Sources of research: literature, observation, experience, logical reasoning. Scientific novelty: the role of an individual in the concept of “computational Leviathan” has been clarified.
