"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."
