Countries of the West, Landes asserts, prospered early through the interplay of a vital, open society focused on work and knowledge, which led to increased productivity, the creation of new technologies, and the pursuit of change. Europe's key advantage lay in invention and know-how, as applied in war, transportation, generation of power, and skill in metalwork. Even such now banal inventions as eyeglasses and the clock were, in their day, powerful levers that tipped the balance of world economic power. Today's new economic winners are following much the same roads to power, while the laggards have somehow failed to duplicate this crucial formula for success. The key to relieving much of the world's poverty lies in understanding the lessons history has to teach us - lessons uniquely imparted in this towering work of history.
