Marx, Karl

"The only antidote to mental suffering is physical pain"

"A man who has no free time to dispose of, whose whole life apart from the mere physical necessities is absorbed in his work for the capitalist, is less than half a man"

"The rich will do anything for the poor but get off their backs"

"Art is always and everywhere the secret confession of society"

"Being determines consciousness; consciousness does not determine being"

"Competition is the expression of the antagonistic character of capitalist production"

"The development of machinery becomes itself a major force of production"

"To make people love their servitude is the task of the propagandist"

"The transformation of labor-power into capital requires the mediation of the money form"

"History is the judge; its executioner is the revolutionary class"

"Human beings make their own history, but they do not make it just as they please"

"The contradiction between the productive forces and the relations of production must be resolved"

"Every society must produce within itself the means to overcome its own contradictions"

"Without consciousness, even the greatest deeds remain unconscious acts"

"The liberation of the worker is the liberation of humanity"

"Ideas become powerful forces when they seize the masses"

"The more a man possesses, the more he is possessed by his possessions."

"History repeats itself, first as tragedy, second as farce."

"The philosophers have only interpreted the world in various ways; the point is to change it."

"Religion is the opium of the people."

"Capital is dead labour that, vampire-like, only lives by sucking living labour."

"The working class is the only class capable of initiating a revolution."

"Ignorance is the only slavery; knowledge is the only freedom."

"To be radical is to grasp things by the root."

"The tradition of all dead generations weighs like a nightmare on the brains of the living."

"Society as a whole is more and more breaking up into two great hostile camps: bourgeoisie and proletariat."

"The purpose of philosophy is not merely to interpret the world, but to transform it."

"Man can create nothing without passion."

"The worker becomes poorer the more wealth he produces."

"Theory becomes a material force as soon as it has gripped the masses."
