Abstract
The subject of this article centres on the theme of philosophical discourse regarding a possible European Federation reflected in the Perpetual Peace sketches of the German philosopher Immanuel Kant and the French philosopher Jean‑Jacques Rousseau. Moving beyond the hypothetical possibilities and frameworks of eternal peace posed by Enlightenment theorists, the article develops into an analysis of the practical execution of these ideas, applying them to a supranational entity such as the European Union. Another crucial point of the work is attributed to the Franco‑German engine, owing to the fact that the philosophical discourse was initiated and concluded by prominent intellectuals from these two nations. The spirit of this intellectual tandem is present on various levels as an integral component of both domestic and foreign policy, as well as a primary contributor to the processes of European integration, particularly in translating the theoretical implications of the idea of eternal peace into reality. This article extracts the primary principles of the theoretical foundations of Perpetual Peace and assesses their correspondence and relevance to the nature of the European Union by defining the intellectual tandem as a framework for further methodological approach.
