Preface: "The history of the question of alliance, integration, and unification of European states along different lines reaches far back. We only have to mention I. Kant and J. C. Bluntschli, who saw the future of Europe in establishing a union of its states based on the rule of law. It was on the grounds of freedom and republican democracy that J. Lorimer of Edinburgh envisaged the possibility of uniting European states. Much like him, Polish thinkers too, including A. Mickiewicz, B. Limanowski, and K. Kelles-Krauz, believed that Europe would unite as soon as its constituent states were driven by shared ideals of freedom and republican democracy."(...)
