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.
Marx, Economic and Philosophic Manuscripts (1844)
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.
Karl Heinrich Marx was born into a comfortable middle-class home in Trier on the river Moselle in Germany on May 5, 1818. He came from a long line of rabbis on both sides of his family and his father, a man who knew Voltaire and Lessing by heart, had agreed to baptism as a Protestant so that he would not lose his job as one of the most respected lawyers in Trier. At the age of seventeen, Marx enrolled in the Faculty of Law at the University of Bonn. At Bonn he became engaged to Jenny von Westphalen, the daughter of Baron von Westphalen , a prominent member of Trier society, and man responsible for interesting Marx in Romantic literature and Saint-Simonian politics. The following year Marx's father sent him to the more serious University of Berlin where he remained four years, at which time he abandoned his romanticism for the Hegelianism which ruled in Berlin at the time.Marx became a member of the Young Hegelian movement. This group, which included the theologians Bruno Bauer and David Friedrich Strauss, produced a radical critique of Christianity and, by implication, the liberal opposition to the Prussian autocracy. Finding a university career closed by the Prussian government, Marx moved into journalism and, in October 1842, became editor, in Cologne, of the influential Rheinische Zeitung, a liberal newspaper backed by industrialists. Marx's articles, particularly those on economic questions, forced the Prussian government to close the paper. Marx then emigrated to France.
Arriving in Paris at the end of 1843, Marx rapidly made contact with organized groups of émigré German workers and with various sects of French socialists. He also edited the short-lived Deutsch-Französische Jahrbücher which was intended to bridge French socialism and the German radical Hegelians. During his first few months in Paris, Marx became a communist and set down his views in a series of writings known as the Economic and Philosophical Manuscripts (1844), which remained unpublished until the 1930s. In the Manuscripts, Marx outlined a humanist conception of communism, influenced by the philosophy of Ludwig Feuerbach and based on a contrast between the alienated nature of labor under capitalism and a communist society in which human beings freely developed their nature in cooperative production. It was also in Paris that Marx developed his lifelong partnership with Friedrich Engels (1820-1895).
Marx was expelled from Paris at the end of 1844 and with Engels, moved to Brussels where he remained for the next three years, visiting England where Engels' family had cotton spinning interests in Manchester. While in Brussels Marx devoted himself to an intensive study of history and elaborated what came to be known as the materialist conception of history. This he developed in a manuscript (published posthumously as The German Ideology), of which the basic thesis was that "the nature of individuals depends on the material conditions determining their production." Marx traced the history of the various modes of production and predicted the collapse of the present one -- industrial capitalism -- and its replacement by communism.At the same time Marx was composing The German Ideology, he also wrote a polemic (The Poverty of Philosophy) against the idealistic socialism of P. J. Proudhon (1809-1865). He also joined the Communist League. This was an organization of German émigré workers with its center in London of which Marx and Engels became the major theoreticians. At a conference of the League in London at the end of 1847 Marx and Engels were commissioned to write a succinct declaration of their position. Scarcely was The Communist Manifesto published than the 1848 wave of revolutions broke out in Europe.
Early in 1848 Marx moved back to Paris when a revolution first broke out and onto Germany where he founded, again in Cologne, the Neue Rheinische Zeitung. The paper supported a radical democratic line against the Prussian autocracy and Marx devoted his main energies to its editorship since the Communist League had been virtually disbanded. Marx's paper was suppressed and he sought refuge in London in May 1849 to begin the "long, sleepless night of exile" that was to last for the rest of his life.
Settling in London, Marx was optimistic about the imminence of a new revolutionary outbreak in Europe. He rejoined the Communist League and wrote two lengthy pamphlets on the 1848 revolution in France and its aftermath, The Class Struggles in France and The 18th Brumaire of Louis Bonaparte. He was soon convinced that "a new revolution is possible only in consequence of a new crisis" and then devoted himself to the study of political economy in order to determine the causes and conditions of this crisis.
During the first half of the 1850s the Marx family lived in poverty in a three room flat in the Soho quarter of London. Marx and Jenny already had four children and two more were to follow. Of these only three survived. Marx's major source of income at this time was Engels who was trying a steadily increasing income from the family business in Manchester. This was supplemented by weekly articles written as a foreign correspondent for the New York Daily Tribune.
One reason why Marx was so slow to publish Capital was that he was devoting his time and energy to the First International, to whose General Council he was elected at its inception in 1864. He was particularly active in preparing for the annual Congresses of the International and leading the struggle against the anarchist wing led by Mikhail Bakunin (1814-1876). Although Marx won this contest, the transfer of the seat of the General Council from London to New York in 1872, which Marx supported, led to the decline of the International. The most important political event during the existence of the International was the Paris Commune of 1871 when the citizens of Paris rebelled against their government and held the city for two months. On the bloody suppression of this rebellion, Marx wrote one of his most famous pamphlets, The Civil War in France, an enthusiastic defense of the Commune.
Marx's health did not improve. He traveled to European spas and even to Algeria in search of recuperation. The deaths of his eldest daughter and his wife clouded the last years of his life. Marx died March 14, 1883 and was buried at Highgate Cemetery in North London. His collaborator and close friend Friedrich Engels delivered the following eulogy three days later:
ايوه انا يا رباب
