We all know that the outstanding characteristic of the human mind in the Middle Ages was its negative attitude to human reason, its lack of faith in the power of reason to direct man’s life and bring him to the goal of real happiness. Reason was almost hated and despised as a dangerous tempter and seducer: it led men away from the pursuit of truth and goodness, and was to be eschewed by all who cared for their souls. Fundamental questions about life and the universe had to receive _super_-rational answers. The simpler and more reasonable the answer, the more suspect and the less satisfactory it was; the stranger the answer, the more violently opposed to sane reason, the more cordial was its welcome and the more ready its acceptance. The famous _Credo quia absurdum_ of one of the Church fathers was the cardinal rule of thought for all cultured nations, Christian and Mohammedan alike. Nor had Judaism escaped the sway of this principle. Not only the mass of the people, but the leaders and teachers, generally speaking, believed in the literal sense of the Scriptures and the Talmud, even where it was plainly contrary to reason. The coarsest and crudest ideas about the nature of the divine power and its relation to men, and about the soul of man and its future in “the world to come”—ideas which reason cannot tolerate for a moment—were almost universally held; and even those learned in the Law staunchly maintained these ideas, because so they had found it written in Bible or Talmud, and that which was written was above reason, and no attention should be paid to that impudent scoffer. It followed naturally from this fundamental point of view that the important things in the sphere of morals were to know and to perform all that was written. The function of reason was not to understand life and the universe, but to understand what was written about life and the universe. The thing best worth doing for a Jew was to ponder on the written word and to work out its details, theoretically and practically, to infinity.[133]
