All civilizations we know about have left a record of their history in material things. We know them through tablets or ruins dug up by archaeologists. But we know of the Jews in ancient times mostly from the ideas they taught and the impact which these ideas had upon other people and other civilizations. There are few Jewish tablets to tell of battles and few Jewish ruins to tell of former splendor. The paradox is that those people who left only monuments behind as a record of their existence have vanished with time, whereas the Jews, who left ideas, have survived.
