Quotes by Karl Marx:

My object in life is to dethrone God and destroy capitalism!

Quoted by W. Cleon Skousen in The Naked Communist.

“The first step in the revolution by the working class is to raise the proletariat lowest social or economic class to the position of ruling class, to win the battle of democracy.” For what purpose? To “abolish private property” to “wrest, by degrees, capital from the bourgeoisie middle class” to “centralize all instruments of production in the hands of the State”
