Mistakes in themselves are unavoidable.

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

Only if you bring together the experience of the concrete struggles conducted by the real masses in the three sectors of the world (which are also called the three sectors of world revolution), then you have an overall, correct view of world reality.

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.

The only conclusion you can draw from the real historical movement is that by and large, in day-to-day life, what Lenin called trade union consciousness dominates the working class. I would call it elementary class consciousness of the working class.

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 cannot make a socialist revolution without really trying.
