Book excerpt: Theodore Kaczynski saw violent collapse as the only way to bring down the techno-industrial system, and in more than a decade of mail bomb terror he killed three people and injured 23 others. One does not need to support the actions that landed Kaczynski in supermax prison to see the value of his essays disabusing the notion of heroic technology while revealing the manner in which it is destroying the planet. For the first time, readers will have an uncensored personal account of his anti-technology philosophy, including a corrected version of the notorious ''Unabomber Manifesto,''Kaczynski, s critique of anarcho-primitivism, and essays regarding ''the Coming Revolution.''
