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

You cannot have a spontaneous socialist revolution.

Revolution is not a goal in itself.

Factions are a sign of illness in a party.

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

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.
