The more workers you have in your organization, the better you are implanted in the working class, the more likely you are to come up with the concrete problems of the class.

And you cannot have a socialist revolution commandeered from the top, ordered around by some omniscient leader or group of leaders

Marxism is always open, always critical, always self-critical.

Workers do not strike every day, they cannot do that the way they function in the capitalist economy. The way they have to live by selling their labor power makes that impossible.

There has been hardly a single year since 1917, and in a certain sense since 1905, without a revolution somewhere in the world in which the workers participated in a rather important way.

For Marx, 'pure' economic theory, that is economic theory which abstracts from a specific social structure, is impossible.

Only under conditions of revolutionary crises do you have the highest level of self-organization; this is the Soviet type of organization, which is to say, workers' councils, people's councils, call them what you want, popular committees.
