Marx, Karl

"Freedom consists of the control of the conditions of one's existence."

"Reason has always existed, but not always in a reasonable form."

"The demand to give up illusions about the condition is the demand to give up a condition which needs illusions."

"Critique must be as harsh as possible because there is no doubt that harshness is a form of charity."

"Competition has replaced feudalism; the bourgeoisie has simplified class antagonisms."

"Consciousness is determined by social being, not the reverse."

"The proletariat alone are a revolutionary class."

"Every relation of mastery involves a relation of dependence."

"Art is the effort of man to express the perception of the universe in a permanent form."

"The development of civilization and industry in general has always shown itself so active in the production of destructive instruments."

"As long as productive labor is not freed, one cannot speak of freedom."

"To imagine that the peasants can ever be revolutionaries is absurd."

"The bourgeoisie cannot exist without constantly revolutionizing the instruments of production."

"Money is the alienated ability of mankind."

"The first condition for the liberation of the working class is the abolition of all classes."

"A specter is haunting Europe, the specter of communism."

"The property of the bourgeois is his capital and his labor-power."

"The worker's existence is reduced to the condition of existence of every other commodity."

"It is not the consciousness of men that determines their being, but their social being that determines their consciousness."

"Labor in the white skin can never free itself as long as labor in the black skin is branded."

"The more the worker expends himself, the more powerful becomes the alien world of objects which he creates."

"Nature is not something separated from human activity by a deep chasm."

"The task is not just to interpret the world but to transform it."

"Quantity transforms into quality and quality into quantity."

"The weapon of criticism cannot, of course, replace criticism by weapons."

"All science would be superfluous if the outward appearance of things directly coincided with their essence."

"The more of his life the worker puts into the object, the less he has left in himself."

"Hegel remarks somewhere that all great world-historic facts and personages appear, so to speak, twice."

"A revolution is necessary not only because the ruling class cannot be overthrown in any other way."

"The bourgeoisie has disclosed how it came to its views by the unveiling of America."
