"The first requisite of all history is the production of the means to satisfy these needs, the production of material life itself."

"A nation cannot be free and at the same time continue to oppress other nations."

"The proletariat will use its political supremacy to wrest, by degree, all capital from the bourgeoisie, to centralise all instruments of production in the hands of the State, i.e., of the proletariat …"

"The old society, with its classes and class antagonisms, is to be replaced by an association, in which the free development of each is the condition for the free development of all."

"The ideas of the ruling class are in every epoch the ruling ideas, i.e. the class which is the ruling material force of society, is at the same time its ruling intellectual force."
