Really good critiques postmodernism. It claims that postmodernism is the ultimate outgrowth of a technological civilization, which has completely overtaken direct, real personal interaction and naturalness. The direct is replaced by the simulated and self-referential. Postmodernism also entails a retreat into total relativism which destroys the ability to critique anything. If all perspectives are just another equally valid narratives decontextualized from any meta-narrative, then whats the point of changing anything? PoMo makes us complacent, or unwilling to be activists or to imagine a better future. Postmodernism in its attempt to smash all false binaries, smashes the binaries of culture and nature, freedom and slavery, ignorance and knowledge. The book argues that postmodernism while associated with the modern left, should really be more strongly associated with capitalism. Postmodernism cutting the legs out from under any social critique, and thus strongly bolsters the status quo which just so happens to be capitalism.
There are also good critiques of modern leftism in here as well, as fundamentally defensive of the nihilistic, technological status quo.
A lot of the critique of modern technology rests on the idea purported by Freud in "Civilization and its Discontents" in which he claims that civilization requires the repression of natural instincts and desires. However it takes this beyond Freudian beliefs to claim that civilization should therefore be dismantled. Zerzan disagrees with the conception of the state of nature as being a "nasty" or "brutish" environment. They see a state of nature as paradisiacal, and rely on archeology, nutritional science, psychology, anthropology, and history to make these judgements.
Crucial to his critique of modernity is the disharmony, alienation, and psychological problems which result from it. There is also the environmental devastation, the dissolution of "Dunbar number" type tribal units, the arms race between medical technology and the diseases produced by the rest of technology, gender inequality, aggression against animals, and a bunch of other crap.
Where face to face interaction breeds authenticity, closeness, and socialness, electronic and urban life produces inauthenticity, alienation, anti-socialness. He sees Japanese culture as the furthest progression of this, as japanese society is also the most technology obsessed one on the planet.
Theres also some stuff about how symbolic language is bad. That was dumb. I get a lot of its critiques of technology and of "mass society". It makes legitimate points. But It never brings forth primitivism as a viable or attractive solution to these problems. It really doesn't explain much about primitivism at all. You mostly have to piece it together through the critiques. So it ends up being a mostly complaintative book which draws illogical conclusions from those complaints.
Most people do acknowledge that technological progress has drawbacks. Most view it as a two steps forward one step backwards scenario. Zerzan posits a sort of one step forward two steps backwards scenario, but isn't very persuasive as to why this model is more correct other than to mock the idea that "more modernity can solve the problems of modernity".
I enjoyed this book for its pre-apocalyptic attitude, critiques of postmodernism, and supremely unique perspective. However, the primitivist thesis is left undeveloped, and many of the more radical critiques (like the one of symbolic thought) were highly uncompelling. His critique of postmodernism would also have been better if he had addressed some of the ways which PoMos try to get out of the uncomfortable philosophical position he accuses them of. Namely, I'm thinking about Stirnerian or Neitzchean postmodernists who wallow in ambiguity, yet are also very individualistic and action oriented.
