The philosopher, social scientist, historian and revolutionary, Karl Marx, is without a doubt the most influential socialist thinker to emerge in the 19th century. Although he was largely ignored by scholars in his own lifetime, his social, economic and political ideas gained rapid acceptance in the socialist movement after his death in 1883. Until quite recently almost half the population of the world lived under regimes that claim to be Marxist. This very success, however, has meant that the original ideas of Marx have often been modified and his meanings adapted to a great variety of political circumstances. In addition, the fact that Marx delayed publication of many of his writings meant that is been only recently that scholars had the opportunity to appreciate Marx's intellectual stature.
His real mission in life was to contribute, in one way or another, to the overthrow of capitalist society and of the state institutions which it had brought into being, to contribute to the liberation of the modern proletariat, which he was the first to make conscious of its own position and its needs, conscious of the conditions of its emancipation. Fighting was his element. And he fought with a passion, tenacity and a success such as few could rival.
“The worker becomes all the poorer the more wealth he produces, the more his production increases in power and range. The worker becomes an ever cheaper commodity the more commodities he creates. With the increasing value of the world of things proceeds in direct proportion to the devaluation of the world of men. Labour produces not only commodities; it produces itself and the worker as a commodity -- and does so in the proportion in which it produces commodities generally.”
