Very good remembrance of Vaclav Havel by Paul Wilson, in NYRB, who was in Prague during his death and subsequent mourning:

All his life, Havel lived by the belief that if you wanted something to happen, you had to do something to make it happen, and damn the consequences, including arrest and prison, and possibly even death. Speaking about the early days of the post-Stalin thaw, he once said: “The more we did, the more we were able to do, and the more we were able to do, the more we did.” It is a fine summary of his attitude, and, in a sense, his legacy. Havel was continually pushing the boundaries of the possible, and in doing so, he was able to create space for others to follow.

This quality is what, quite properly, put him in the same league as Nelson Mandela and Martin Luther King Jr. But what put him in a league of his own is the corollary: you act not to achieve a certain outcome; you act because it is the right thing to do. That is what he meant by “living in truth,” a notion he explores in some depth in his most radical and enduring work: The Power of the Powerless.
