Anarchist authority Murray Bookchin is a long-time target of criticism from Bob Black, who has devoted many letters to exposing the views of the guru. This text is an example where the antagonists came together in the arena of anthropology, such an important territory of anarchist thought. And even though the floor is given mainly to Black, here he quotes liberally in order to debunk his opponent, who, although he has more supporters, has very few arguments against Bob Black’s devastating criticism.
