John Zerzan (/ˈzɜːrzən/ ZUR-zən; born August 10, 1943) is an American anarchist and primitivist ecophilosopher and author. His works criticize agricultural civilization as inherently oppressive, and advocates drawing upon the ways of life of hunter-gatherers as an inspiration for what a free society should look like. Some subjects of his criticism include domestication, language, symbolic thought (such as mathematics and art) and the concept of time.
