Abstract
B a c k g r o u n d. This article represents a reconstructive analysis of the idea of perpetual peace in the works of Immanuel Kant and liberal thinkers of the second half of the twentieth century as the forerunners and representatives of the democratic peace theory. The study examines the process of development and evolution of the concept of perpetual and universal peace in liberal discourse and its difference from the original project of I. Kant. M e t h o d s. Currently, the following methods are used in the work: the principle of abstraction, that is, the rejection of a number of properties, connections and relations of the object or phenomenon under study, which are not essential for solving the assigned problems, to concentrate on its separate elements; the principle of objectivity, that is, taking into account all factors that simplify the process of studying selected objects, phenomena and processes; the principle of unity of theory and practice, taking into account their interdependence. the principle of rational reconstruction, that is, consideration of the history of the development of selected issues within the framework of the rational requirements of scientific discourse. R e s u l t s. In the process of research, tendencies towards the development of the idea of perpetual peace within the framework of liberal humanistic discourse were revealed, which certainly led to changes in the fundamental provisions of the original concept of perpetual peace, endowing it with democratic and market-liberal elements more characteristic of current scientific discourse. C o n c l u s i o n s. The Kantian project of perpetual peace forms the fundamental basis of the liberal democratic peace theory. The idea of a world without war, as well as the mechanism for its establishment and support through the creation of a single political and economic space within the framework of a world federation, served as the ideological basis for the democratic peace theory, however, in the process of its adaptation to the conditions of the new discourse, the original project underwent serious changes in its basis. Using the example of the evolutionary historical process around the "perpetual peace" project, we can trace the general mechanism for the development of scientific knowledge within the framework of a changing discourse, which, on the one hand, adapts a dynamically developing idea to the more current requirements of scientific knowledge, but on the other hand, preserves the main direction of the chosen problematic for preservation integrity of scientific discourse.
