This book sheds new light on the origins and nature of modern military thinking. The ideas of Carl von Clausewitz (1780-1831)--which remain at the core of strategic analysis today--have previously been examined apart from their 18th-century cultural and philosophical roots. Gat here demonstrates the extent to which culture affects military theory by relating a series of military thinkers to their cultural backgrounds. He also provides a provocative critique of Clausewitz's classic work On War, and demonstrates how the major currents of modern military thought have evolved from the cultural frameworks and historical outlooks of both the German Movement and the Enlightenment.
