You cannot make a socialist revolution without really trying.

There is a process of social and of political differentiation going on in the real working class all the time.

Mistakes in themselves are unavoidable.

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.

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

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.

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.
