Perhaps [‘the history of anarchism, almost alone among modern social movements, is one of unrelieved failure.’]; but its failures are different and less shameful than the failures of Marxism. There are many ways for a social movement to fail, and I prefer those that don’t result in the murder of tens of millions of human beings.
Maybe a good question for leaders of any social movement: how will you fail? Failure is guaranteed but not all failure is equal.
