Quotes:Karl Marx

On philosophy
"Philosophers have only interpreted the world, in various ways; the point, however, is to change it." [Emphasis added] —Theses on Feuerbach, 1845
On communism
"It is high time that Communists should openly, in the face of the whole world, publish their views, their aims, their tendencies, and meet this nursery tale of the spectre of Communism with a Manifesto of the party itself." —The Communist Manifesto, 1848
"The theory of Communism may be summed up in the single sentence: Abolition of private property." [Emphasis added] —The Communist Manifesto, 1848
"The Communists disdain to conceal their views and aims. They openly declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win.
WORKERS OF THE WORLD, UNITE!" [Emphasis added] —The Communist Manifesto, 1848
On history
"The history of all hitherto existing society is the history of class struggles." —The Communist Manifesto, 1848
"Men make their own history, but they do not make it as they please; they do not make it under self-selected circumstances, but under circumstances existing already, given and transmitted from the past. The tradition of all dead generations weighs like a nightmare on the brains of the living. And just as they seem to be occupied with revolutionizing themselves and things, creating something that did not exist before, precisely in such epochs of revolutionary crisis they anxiously conjure up the spirits of the past to their service, borrowing from them names, battle slogans, and costumes in order to present this new scene in world history in time-honored disguise and borrowed language. Thus Luther put on the mask of the Apostle Paul, the Revolution of 1789-1814 draped itself alternately in the guise of the Roman Republic and the Roman Empire, and the Revolution of 1848 knew nothing better to do than to parody, now 1789, now the revolutionary tradition of 1793-95. In like manner, the beginner who has learned a new language always translates it back into his mother tongue, but he assimilates the spirit of the new language and expresses himself freely in it only when he moves in it without recalling the old and when he forgets his native tongue.
When we think about this conjuring up of the dead of world history, a salient difference reveals itself. Camille Desmoulins, Danton, Robespierre, St. Just, Napoleon, the heroes as well as the parties and the masses of the old French Revolution, performed the task of their time – that of unchaining and establishing modern bourgeois society – in Roman costumes and with Roman phrases." [Emphasis added] —The Eighteenth Brumaire of Louis Bonaparte, 1852
