For Christians and Jews, the Bible is the cornerstone of society. It's the source of history, models, ethics and morals. The stories in the Old Testament kept the Jewish identity in tact for over 2000 years. Sacks sees it as essential that Biblical ideas remain central to our society, otherwise we'll be heading for unchartered territory.
As a speechwriter, I found the book fascinating. Sacks picks up on speeches by John Major and Stanley Baldwin, and points out how unsatisfactory they are when you yearn for some idea of a nation. There are too many static, sentimental visions of England. Unlike America, there is no creative, and dynamic story of the English sharing a common destiny. This is what Sacks says is required.
