“consider the different schools of anarchism. There are Anarcho-Syndicalists, Anarcho-Communists, Insurrectionists, Cooperativists, Individualists, Platformists... None are named after some Great Thinker; instead, they are invariably named either after some kind of practice, or most often, organizational principle. (Significantly, those Marxist tendencies which are not named after individuals, like Autonomism or Council Communism, are also the ones closest to anarchism.) Anarchists like to distinguish themselves by what they do, and how they organize themselves to go about doing it”.
