Civilization might have been spared much of the damage suffered in the world wars this century if the influence of Clausewitz's On War had been blended with and balanced by a knowledge of Sun-tzu's The Art of Warfare. B.H. Liddel Hart For two thousand years, Sun-tzu's The Art of Warfare was the indispensable volume of warcraft. Although his work is the first known analysis of war and warfare, Sun-tzu struck upon a thoroughly modern concept; 'The supreme art of war is to subdue the enemy without fighting.' Karl von Clausewitz, the canny military theorist who famously declared that war is a continuation of politics by other means, also claims paternity of the notion 'total war.' His is the magnum opus of the era of the French Revolution and the Napoleonic vars.
