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 us, Marxism is always open because there are always new experiences, there are always new facts, including facts about the past, which have to be incorporated in the corpus of scientific socialism.

You can have relatively high levels of class consciousness with a lower level of class militancy than one would have expected.

There are no conditions in which we subordinate the interests of the class as a whole to the interests of any sect, any chapel, any separate organization.

Precisely because Marx was convinced that the cause of the proletariat was of decisive importance for the whole future of mankind, he wanted to create for that cause not a flimsy platform of rhetorical invective or wishful thinking, but the rock-like foundation of scientific truth.

You cannot make a socialist revolution without really trying.

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.
