All free countries are wrestling with the same problem: how to combine liberty and diversity. Take a walk through the streets of any of our major cities and you see how people with different backgrounds, customs, faiths and languages are living cheek by jowl. Moreover, as the world is shrunk by cheap air travel and the Internet, what happens in Pakistan happens also in Bradford. Arabs radicalised in Hamburg crash a plane in New York. Anger in Morocco becomes mayhem in Madrid. This book will take a fresh approach, and it will be created by an unusual, even unique method. Rather than concentrating, more or less hysterically, on one or more apsects of the problem (Terrorism! Islam! Immigration!) it will calmly suggest the things on which most reasonable people can agree. These universal principles will then be offered for debate.
