On the contrary, history generally confirms that the more conscious and the better you are organized in vanguard organizations, the more constructively you operate in the mass organizations of the working class.

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 Marx, 'pure' economic theory, that is economic theory which abstracts from a specific social structure, is impossible.

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.

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.

Periodically, the workers do revolt against bourgeois society, not by a hundred, five hundred, or a thousand, but by the millions.

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