The history of all countries shows that the working class exclusively by its own effort is able to develop only trade-union consciousness.

Capitalists are no more capable of self-sacrifice than a man is capable of lifting himself up by his own bootstraps.

A revolution is impossible without a revolutionary situation; furthermore, not every revolutionary situation leads to revolution.
