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.

You need a vanguard organization in order to overcome the dangerous potential brought about by the uneven development of class militancy and class consciousness.

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

Factions are a sign of illness in a party.

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.

Revolution is an instrument, like a party is an instrument.

I do not believe in self-proclaimed parties.
