About the Author

Stephen Peter Rosen is a distinguished scholar and author whose work bridges the disciplines of international relations, history, and evolutionary biology to explore the profound influences shaping human conflict and cooperation. With a career spanning decades as a professor at Harvard University and a senior fellow at institutions like the Brookings Institution, Rosen draws on rigorous academic research to illuminate how innate human traits drive the strategies of war and peace. His seminal book, War and Human Nature, offers a groundbreaking analysis of how evolutionary psychology underpins military decision-making and state behavior, challenging conventional theories with evidence from anthropology and political science. Rosen's insights continue to influence policymakers, military strategists, and academics, providing a nuanced understanding of humanity's perennial struggle with aggression and alliance-building in an increasingly complex global landscape.
