Matt Welch has a post at Hit & Run quoting his profile of Havel from 2003:
Like Orwell, Havel was a fiction writer whose engagement with the world led him to master the nonfiction political essay. Both men, in self-described sentiment, were of “the left,” yet both men infuriated the left with their stinging criticism and ornery independence. Both were haunted by the Death of God, delighted by the idiosyncratic habits of their countrymen, and physically diminished as a direct result of their confrontation with totalitarians (not to mention their love of tobacco). As essentially neurotic men with weak mustaches, both have given generations of normal citizens hope that, with discipline and effort, they too can shake propaganda from everyday language and stand up to the foulest dictatorships.
Unlike Orwell, Havel lived long enough to enjoy a robust third act, and his last six months in office demonstrated the same kind of restless, iconoclastic activism that has made him an enemy of ideologues and ally of freedom lovers for nearly five decades.
