Alexander Wendt’s Social Theory of International Politics at Twenty-five: Some Reflections

Twenty-five years have passed since Alexander Wendt presented his Social Theory of International Politics . However, it is considered a highly significant contribution to international relations theory. This article assesses Wendt’s theoretical work, examining his contributions and unresolved issues. Wendt’s real accomplishment was to do more than show that ideas, norms, and identities are of some import; he set about reconstructing systemic theory on a social ontology in which interaction constitutes both interests and identities. He challenged neorealism’s materialist and individualist foundations by employing structuration theory, scientific realism, holism, and structural idealism, while still prioritizing the state, anarchy, and systemic analysis within the field. He presented Hobbesian, Lockean, and Kantian cultures of anarchy, arguing that no universal logic dictates anarchy and that conflict, rivalry, and cooperation stem from historical social relationships. We also analyze Wendt’s attempt to integrate rationalist explanations into a constructivist framework, a blend that likely contributes to his significant influence in the field. However, this same synthesis creates conflict. Reconciling his commitment to scientific realism with constructivism’s inherent nature is difficult. His linguistic approach is debatable, and his state-focused perspective does not adequately question how states and the international system formed. Another issue is seeing identities as socially constructed yet consistently explanatory. However, none of this diminishes the importance of Wendt’s work. On the contrary, these open questions are part of what makes Social Theory so intellectually productive: it has changed the way we debate theory without ever closing the book on it.
