“When the workers of a single factory or of a single branch of industry engage in struggle against their employer or employers, is this class struggle? No, this is only a weak embryo of it. The struggle of the workers becomes a class struggle only when all the foremost representatives of the entire working class of the whole country are conscious of themselves as a single working class and launch a struggle that is directed, not against individual employers, but against the entire class of capitalists and against the government that supports that class. Only when the individual worker realizes that he is a member of the entire working class, only when he recognises the fact that his petty day-to-day struggle against individual employers and individual government officials is a struggle against the entire bourgeoisie and the entire government, does his struggle become a class struggle.”

“‎The party that leans upon the workers but serves the bourgeoisie, in the period of the greatest sharpening of the class struggle, cannot but sense the smells wafted from the waiting grave.”

“Philosophy is, in the last instance, class struggle in the field of theory.”

“A class struggling to assert itself, to discover its true shape, which lies hidden, as does the statue in the marble, in the hard, resisting material of life itself, be different from the same class when chisel and mallet have been laid aside, and it has actually become what it had so long been struggling to be.”

“There will always be new opposites, class struggles and uprisings. History has no ending.”

“In struggling against anguish one never produces serenity; the struggle against anguish only produces new forms of anguish. ”
