Why have I written a history of the Jews? There are four reasons. The first is sheer curiosity. When I was working on my History of Christianity, I became aware for the first time in my life of the magnitude of the debt Christianity owes to Judaism. It was not, as I had been taught to suppose, that the New Testament replaced the Old; rather, that Christianity gave a fresh interpretation to an ancient form of monotheism, gradually evolving into a different religion but carrying with it much of the moral and dogmatic theology, the liturgy, the institutions and the fundamental concepts of its forebear. I thereupon determined, should opportunity occur, to write about the people who had given birth to my faith, to explore their history back to its origins and forward to the present day, and to make up my own mind about their role and significance. The world tended to see the Jews as a race which had ruled itself in antiquity and set down its records in the Bible; had then gone underground for many centuries; had emerged at last only to be slaughtered by the Nazis; and, finally, had created a state of its own, controversial and beleaguered. But these were merely salient episodes. I wanted to link them together, to find and study the missing portions, assemble them into a whole, and make sense of it.
My second reason was the excitement I found in the sheer span of Jewish history. From the time of Abraham up to the present covers the best part of four millennia. That is more than three-quarters of the entire history of civilized humanity. I am a historian who believes in long continuities and delights in tracing them. The Jews created a separate and specific identity earlier than almost any other people which still survives. They have maintained it, amid appalling adversities, right up to the present. Whence came this extraordinary endurance? What was the particular strength of the all-consuming idea which made the Jews different and kept them homogeneous? Did its continuing power lie in its essential immutability, or its capacity to adapt, or both? These are sinewy themes with which to grapple.
My third reason was that Jewish history covers not only vast tracts of time but huge areas. The Jews have penetrated many societies and left their mark on all of them. Writing a history of the Jews is almost like writing a history of the world, but from a highly peculiar angle of vision. It is world history seen from the viewpoint of a learned and intelligent victim. So the effort to grasp history as it appeared to the Jews produces illuminating insights. Dietrich Bonhoeffer noticed this same effect when he was in a Nazi prison. ‘We have learned’, he wrote in 1942, ‘to see the great events of world history from below, from the perspective of those who are excluded, under suspicion, ill-treated, powerless, oppressed and scorned, in short those who suffer.’ He found it, he said, ‘an experience of incomparable value’. The historian finds a similar merit in telling the story of the Jews: it adds to history the new and revealing dimension of the underdog.
Finally the book gave me the chance to reconsider objectively, in the light of a study covering nearly 4,000 years, the most intractable of all human questions: what are we on earth for? Is history merely a series of events whose sum is meaningless? Is there no fundamental moral difference between the history of the human race and the history, say, of ants? Or is there a providential plan of which we are, however humbly, the agents? No people has ever insisted more firmly than the Jews that history has a purpose and humanity a destiny. At a very early stage in their collective existence they believed they had detected a divine scheme for the human race, of which their own society was to be a pilot. They worked out their role in immense detail. They clung to it with heroic persistence in the face of savage suffering. Many of them believe it still. Others transmuted it into Promethean endeavours to raise our condition by purely human means. The Jewish vision became the prototype for many similar grand designs for humanity, both divine and man-made. The Jews, therefore, stand right at the centre of the perennial attempt to give human life the dignity of a purpose. Does their own history suggest that such attempts are worth making? Or does it reveal their essential futility? The account that follows, the result of my own inquiry, will I hope help its readers to answer these questions for themselves.
