Query: Essays and Tributes

For the information of those interested enough to read this review, this book contains six of Vaclav Havel's essays (including the excellent "Power of the Powerless" and an open letter to Gustav Husak) as well as sixteen letters or essays of tribute to Havel (including an essay by Samuel Beckett and another by Arthur Miller). Havel's essays are published in several other works, but I haven't found the letters to and about him in any other book. This is an interesting book about a dissident who, while once challenging authority, had the courage to assume it and with it all of its moral complexities.I also recommend James Sire's book "Vaclav Havel: The International Conscience of International Politics" for a concise and readable introduction to the man and his work.
