This book explores the complex domain of social reality, asking what this reality is, how it is composed and what its dynamics are in both theoretical and practical terms. Through the examination of some of the most important contemporary theories of social ontology, the book discusses the fundamentals of the discipline and lays the foundations for its development in the political sphere. By analyzing the notion of State and the redesign of ontology, the author argues in favor of a realist conception of the State and shows the reasons why this promotes a better understanding of the dynamics of power and the actualization of a greater justice between generations. This book captures the relationship between different generations within the same political context, and presents it as a necessary condition for the re-definition of the concepts of State and meta-State.
