“Some activists lament how few anti-authoritarians there appear to be in the United States. One reason could be that many natural anti-authoritarians are now psychopathologized and medicated before they achieve political consciousness of society’s most oppressive authorities.”

Prologue
Anarchism : A History of Libertarian Ideas and Movements (1962)
Context: It is the general idea put forward by Proudhon in 1840 that unites him with the later anarchists, with Bakunin and Kropotkin, and also with certain earlier and later thinkers, such as Godwin, Stirner, and Tolstoy, who evolved anti-governmental systems without accepting the name of anarchy; and it is in this sense that I shall treat anarchism, despite its many variations: as a system of social thought, aiming at fundamental changes in the structure of society and particularly — for this is the common element uniting all its forms — at the replacement of the authoritarian state by some form of non-governmental cooperation between free individuals.

Introduction : The Libertarian Tradition
Communalism (1974)
Context: People who believe in libertarian communism can be grouped roughly under three general theories, each with its old masters, theoreticians, leaders, organizations, and literature. First there are the anarchists in a rather limited variety: communist-anarchists, mutualists, anarcho-syndicalists, individual anarchists, and a few minor groups and combinations. Second, the members of intentional communities, usually but by no means always religious in inspiration. The words “communalism” and “communalist” seem to have died out and it would be good to appropriate them to this group, although the by now too confusing word “communist” actually fits them best of all. Third, there are the Left Marxists, who prior to 1918 had become a widespread movement challenging the Social Democratic Second International. It was to them the Bolsheviks appealed for support in the early days of their revolution. Lenin’s The State and Revolution is an authoritarian parody of their ideas. They in turn have called it “the greatest pre-election pamphlet ever written: ‘Elect us and we will wither away’.” Against them Lenin wrote Leftism: An Infantile Disorder. There is a story that, when the Communist International was formed, a delegate objected to the name. Referring to all these groups he said: “But there are already communists.” Lenin answered: “Nobody ever heard of them, and when we get through with them nobody ever will.” Today these ideas are more influential than they ever have been.
