"A spectre is haunting Europe — the spectre of communism. All the powers of old Europe have entered into a holy alliance to exorcise this spectre: Pope and Tsar, Metternich and Guizot, French Radicals and German police-spies."
"The history of all hitherto existing society is the history of class struggles.
"The bourgeoisie, historically, has played a most revolutionary part." Karl Marx and Friedrich Engels: Manifesto of the Communist Party
"The wealth of those societies in which the capitalist mode of production prevails, presents itself as “an immense accumulation of commodities,” its unit being a single commodity. Our investigation must therefore begin with the analysis of a commodity." Karl Marx: Capital Vol I, opening words.
"WE have seen how money is changed into capital; how through capital surplus-value is made, and from surplus-value more capital. But the accumulation of capital presupposes surplus-value; surplus-value presupposes capitalistic production; capitalistic production presupposes the preexistence of considerable masses of capital and of labour-power in the hands of producers of commodities. The whole movement, therefore, seems to turn in a vicious circle, out of which we can only get by supposing a primitive accumulation (previous accumulation of Adam Smith) preceding capitalistic accumulation; an accumulation not the result of the capitalist mode of production, but its starting point.
The capitalist system presupposes the complete separation of the labourers from all property in the means by which they can realise their labour. As soon as capitalist production is once on its own legs, it not only maintains this separation, but reproduces it on a continually extending scale. The process, therefore, that clears the way for the capitalist system, can be none other than the process which takes away from the labourer the possession of his means of production; a process that transforms, on the one hand, the social means of subsistence and of production into capital, on the other, the immediate producers into wage-labourers. The so-called primitive accumulation, therefore, is nothing else than the historical process of divorcing the producer from the means of production. It appears as primitive, because it forms the pre-historic stage of capital and of the mode of production corresponding with it." Karl Marx Capital Vol I Part III, chapter XXVI
"The Enclosures, however, are not a one time process, exhausted at the dawn of capitalism. They are a regular return on the path of accumulation and a structural component of class struggle. Any leap in proletarian power demands a dynamic capitalist response: both the expanded appropriation of new resources and new labor power, and the extension of capitalist relations, or else capitalism is threatened with extinction.
