" Given everything we know about the universe it would seem utterly impossible for any sane person to believe that the ultimate truth about the universe and human existence is the story of Israeli, German or Russian nationalism – or indeed of nationalism in general. A story that ignores almost the whole of time, the whole of space, the Big Bang, quantum physics and the evolution of life is at most just a tiny part of the truth. Yet people somehow manage not to see beyond it.
Indeed, billions of people throughout history have believed that for their lives to have meaning, they don’t even need to be absorbed into a nation or a great ideological movement. It is enough if they just ‘leave something behind’, thereby ensuring that their personal story continues beyond their death. The ‘something’ I leave behind is ideally my soul or my personal essence. If I am reborn in a new body after the death of my present body, then death is not the end. It is merely the space between two chapters, and the plot

“that began in one chapter will carry on into the next. Many people have at least a vague faith in such a theory, even if they do not base it on any specific theology. They don’t need an elaborate dogma – they just need the reassuring feeling that their story continues beyond the horizon of death. "
