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?
