Query: An astonishing, discouraging, truly important book

This book deserves to take its place among the classics that explore the possibilities of creating a just and content society. Unlike Walden 2, or Utopia, the thesis of the Dispossessed is that utopias cannot be realized: the anarchist society of the title already carries the seeds of its own destruction. This is a necessary read for those who mistakenly believe that the "End of History" has arrived.
