"The great statesman has always used tariffs deliberately. It is only when political energy is dead that people refer to them as expedients. Bismarck understood the subject at a time when the mind of the Englishman was becoming confused. Like all statesmen he asked himself first where he was going, and secondly what was his object in arriving. He knew that trade could be raised to any state of artificiality if it could be controlled within a self-sufficient unit. Although he did not possess such a unit he was not frustrated, and counted on an armed conquest at some future date... In 1834 he used Free Trade to unify Germany by the Zollverein. The same policy used Protection to encourage intensively the larger unit of the Nation. Here was an example of the use of each system according to the end in view and proof of the subservience of economics to the politic will."
