This article compares Waltz and Kant as theorists who explicitly advocate a systemic approach to international relations. Waltz and Kant are compared with respect to their views on the nature of systemic approaches, the composition and dynamics of the international system, and the relationship between the international system and world society. It is argued that there are deep underlying similarities between their views on the nature of systemic approaches to international relations that may facilitate a much broader account of the international system. A final section examines the relevance of a Kantian view of the international system to the post-Cold War era by comparing its insights to those offered by neorealist and classical realist perspectives.
