Kant’s domestic analogy: International and global order

The domestic analogy is an old but persistent problem in theories of international politics. This paper examines the problem in the work of Immanuel Kant, whose political writings are often cited as a paradigmatic example of the analogy between individuals and states. Attention to Kant’s own conception of analogy, however, shows that the political writings are structured by another “domestic analogy”—between international and cosmopolitan right. This analogy, I argue, is based on a correspondence between the systematic unity of the international and the spherical globe, the figure that for Kant represents the boundaries of world order. International and cosmopolitan right are thus distinguished on the basis of a geopolitical criterion: the global scope of international order. This analogy of order, the paper argues, thus works to domesticate world politics through the structural form of international order. To the extent that contemporary theories of international relations rely on this conception of order, they accept Kant’s answer to the problem of perpetual peace. The paper concludes by drawing broader conclusions from the analysis about the domestic analogy, international order, and world politics.
