Communism is an old idea in the world. Let’s call it ancient, for it may as well be our antiquity. We need not track down its origins in the alleyways of insurrection, only know that millions have struggled and died in its name. In this sense, it is not just an idea but a real force in history, product of and factor in a proletarian movement that has for at least two centuries now posed the overcoming of capitalism by classless, stateless, moneyless society. In fact, what’s remarkable about the history of the workers’ movement of the last two centuries is that this real ideal has until recently not only seemed inevitable but obvious. Even where they disagreed, violently, about how to achieve such a state of affairs, anarchists, communists, socialists, Marxists, syndicalists, and even some liberals, all stood joined by a common vision of a future classless society.
