A Political Constitution for the Pluralist World Society?

The chances of the project of a “cosmopolitan order” being successful are not worse now than they were in 1945 or in 1989–1990. This does not mean that the chances are good, but we should not lose sight of the scale of things. The Kantian project first became part of the political agenda with the League of Nations, in other words after more than 200 years; and the idea of a cosmopolitan order first received a lasting embodiment with the foundation of the United Nations (UN). This process points toward a continuation of the Kantian project. We can still take our cue from Kant's idea of a cosmopolitan condition if we simply construe it in sufficiently abstract terms. I wish to show first of all why I consider the Kantian alternative between a world of republic and a league of nations to be incomplete (section I) and will then go on to outline how we can reconceptualize the Kantian project under contemporary conditions (section II). And I shall close by addressing an actual challenge to which that project might well offer the most promising response (section III).
