High Quality Content by WIKIPEDIA articles! Social Anarchism or Lifestyle Anarchism: An Unbridgeable Chasm is a polemical essay written by Murray Bookchin and published as a book in 1995. It is a critique of deep ecology, bio-centrism and lifestyle anarchism. Bookchin sets his social anarchism in opposition to individualist, primitivist and post-modern forms of anarchism (represented, he maintains, by such anarchist philosophers as John Zerzan and Hakim Bey). It has provoked criticism from other anarchists, including Bob Black, who view Bookchin`s polemic as misguided.
