John Zerzan is an anarchist and philosopher whose critique of civilization and call for a non-domesticated form of life has been described as “primitivist”. Zerzan has analyzed agricultural and industrial society in detail and has drawn on anthropological research on prehistoric and other “primitive” societies in describing egalitarian and non-alienated ways of communal life. Zerzan has contributed to anarchist theory for decades, especially on topics of ecology, anti-technology, post-leftism and postmodernity. He is the author of several books, including Against Civilization, Running On Emptiness and Twilight of the Machines. He has also served as editor of Green Anarchy: A Journal of Anti-Civilization Theory and Practice since 2001.
