" Economic progress is the product of rationalization. Rabbinical Judaism is essentially a method whereby ancient laws are adapted to modern and differing conditions by a process of rationalization. The Jews were the first great rationalizers in world history. This had all kinds of consequences as we shall see, but one of its earliest, in a worldly sense, was to turn Jews into methodical, problem-solving businessmen. A great deal of Jewish legal scholarship in the Dark and Middle Ages was devoted to making business dealings fair, honest and efficient. "

― Paul Johnson , A History of the Jews
