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.

Marxism is always open, always critical, always self-critical.

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.

You cannot make a socialist revolution without really trying.

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

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.
