This exciting and thoughtful book sheds new light on the relation between liberalism and realism in International Relations and makes an important argument for interdisciplinary research, bringing in Karl Mannheim into IR.

"Hvidsten applies his dialectical approach to contemporary IR theory with a steady hand. The work is insightful and original and arrives at a synthesis that calls for openness and dialog in our troubled times."
