Das Kapital

• 1. Introduction

  ›

  Das Kapital arrived in bookshops in Hamburg in September 1867 as a single German-language volume of dense, technical prose. Karl Marx had spent decades preparing it. He had filled notebooks with excerpts from economists, argued with utopian socialists in Paris, survived exile in London on the edge of poverty, and endured liver problems and carbuncles that he blamed on the stress of the work. And yet, when the first edition of 1,000 copies reached German readers, the response was almost silence.

  What was this book, exactly? Marx called it a critique of political economy. Its central claim was that capitalism runs not on ingenuity or trade but on unpaid work extracted from labourers who have no other choice but to sell their time. That claim would become one of the most argued-over ideas in modern history.

  The work grew over decades into three volumes. Only the first appeared while Marx lived. His collaborator Friedrich Engels assembled the other two from fragmentary, sometimes disordered manuscripts after Marx died in 1883. Volume II came out in 1885; Volume III followed in 1894. Together they form an analysis of how capitalist society produces wealth, circulates it, and distributes it as wages, profit, interest, and rent.

  The questions Das Kapital raises have never gone away. Where does profit actually come from? Why do wages tend to stay low even when economies grow? How does a system based on free exchange end up concentrating wealth at one pole and misery at the other? The chapters that follow trace how Marx built his answers.

• 2. Three Traditions, One Critique

  ›

  Marx's dissertation was on Epicurus, and he was thoroughly trained in Aristotle before he ever opened a book on economics. That philosophical formation shaped everything he later wrote. When he turned to economics in the 1840s, he did not simply read it on its own terms. He read it the way a philosopher reads a text: looking for hidden assumptions, unquestioned categories, and internal contradictions.

  The economists he studied ranged from William Petty and John Locke in the seventeenth century through Adam Smith, Thomas Malthus, and David Ricardo in the nineteenth. He also engaged the French Physiocrats, including Francois Quesnay and Anne Robert Jacques Turgot, and later economists such as Jean-Baptiste Say. His extensive notes on these thinkers were eventually published as Theories of Surplus Value, a work that shows his method: accept certain insights, then identify the gaps the thinker could not see.

  Marx's specific quarrel with David Ricardo is revealing. Ricardo viewed labour as the transhistorical source of all wealth, a universal truth about human existence. Marx insisted that labour as it operates under capitalism, what he called abstract labour, is a historically specific social form unique to that system. That distinction, between an eternal natural fact and a contingent historical arrangement, is the pivot on which his entire critique turns.

  From German philosophy, and especially from Georg Wilhelm Friedrich Hegel, Marx borrowed the dialectical method. He then subjected that method to a materialist correction, arguing that social consciousness is determined by material conditions, not the reverse. Some later interpreters read this move not as a simple inversion of Hegel but as an attempt to show that the self-grounding, self-moving Subject in Hegel's idealism is in fact the alienated social structure of capital itself.

  The third tradition was French utopian socialism. Figures such as Henri de Saint-Simon, Charles Fourier, and Pierre-Joseph Proudhon shaped the political atmosphere Marx entered during his time in Paris in 1843-1844. He wanted to convert what he considered shallow utopianism into what he called scientific socialism, by applying German critical philosophy to reveal the real dynamics that the utopians had only morally condemned. His engagement with Proudhon in particular was sharp and sustained.

• 3. The Commodity and Its Secret

  ›

  Marx opens Volume I not with a factory, a wage, or a capitalist, but with a commodity. Wealth in capitalist societies "appears as" an "immense collection of commodities". That word appears is doing serious work: what looks like a natural fact turns out to be a historically specific form.

  Every commodity has two faces. It has a use-value, satisfying some human want or need, and an exchange-value, the ratio in which it trades for other commodities. Marx's question is what makes exchange possible at all. What do a coat and twenty yards of linen have in common that allows them to stand as equivalents? His answer is value: a social substance representing congealed abstract human labour.

  The magnitude of value is determined by socially necessary labour time, meaning the average time required to produce a commodity under normal conditions and with the average degree of skill prevalent in that society. Concrete labour, such as weaving or tailoring, produces specific use-values. Abstract labour, the general social mediation through which producers relate to one another in a commodity-producing society, creates value. This distinction between concrete and abstract labour is not a physiological one; it is a social and historical one specific to capitalism.

  From the analysis of value, Marx moves to money. The exchange of commodities requires a universal equivalent, historically gold or silver. Money serves as a measure of value, a medium of circulation, a store of value, a means of payment for debts, and world money in international trade. Crucially, Marx argues that value cannot be expressed or realised without money; his theory of value is from the start a monetary theory.

  The section closes with what Marx calls commodity fetishism. The social relations between producers, which are relations between human beings, appear instead as objective relations between things. The market makes this seem natural. Marx described it as a "phantom-like" or "spectral" objectivity, a socio-natural property that belongs not to the commodities themselves but to a specific social structure. Literary scholar Francis Wheen argued that Capital's complex, multilayered style was a deliberate strategy to do justice to the "deranged logic" of a system where human relations are disguised as relations between objects.

• 4. Labour, Exploitation, and the Working Day

  ›

  Labour power, the capacity to work, is the commodity at the centre of Marx's explanation of profit. Two conditions must hold for it to appear on the market. The worker must be a free proprietor of their own capacity, able to sell it for a defined period. And the worker must also be free in a second, darker sense: owning no means of production, compelled to sell their labour power to survive. Marx called this the worker's "double freedom", a condition that did not arise naturally but was created historically through what he called primitive accumulation, the forcible separation of producers from the land and tools they had once used.

  The value of labour power is determined, like any commodity, by the socially necessary labour time required for its reproduction. That means the food, clothing, and shelter a worker needs to remain able to work and to raise a new generation of workers. Marx emphasised that this value contains a "historical and moral element", varying according to the level of civilisation, class struggle, and social custom.

  The secret of profit lies in the gap between what labour power is worth and what it can produce. The capitalist buys labour power at its value and then puts it to work. In the labour process, the worker creates more value than the value of their own labour power. That surplus, which the capitalist appropriates without paying for it, is surplus value.

  Marx identified two ways of extracting more surplus value. Absolute surplus value is produced by lengthening the working day, so the worker spends more hours producing for the capitalist beyond the time needed to reproduce their own wages. Relative surplus value is produced by raising productivity in the industries that make the goods workers buy, thereby cheapening the value of labour power itself and leaving a larger share of the working day as unpaid time.

  The working day became a site of sustained historical conflict. Marx described capital as "dead labour which, vampire-like, lives only by sucking living labour". Between the capitalist's right to extract maximum use from purchased labour power and the worker's right to rest and health, "between equal rights, force decides". The Factory Acts in Britain were the product of that force: protracted class struggle and state intervention that set limits on hours, particularly for women and children in various industries.

• 5. The Machinery of Accumulation

  ›

  Cooperation, division of labour, and machinery are the three main methods Marx analyses in his account of relative surplus value. When many workers are brought together under one capitalist, their combined effort generates a social productive power greater than the sum of individual efforts. This collective force appears, Marx noted, as a productive power of capital itself rather than of the workers who produce it.

  Manufacture, based on handicraft skills broken into specialised partial operations, raises productivity but also, in Marx's phrase, "converts the worker into a crippled monstrosity" by suppressing a "whole world of productive drives and inclinations". Intellectual knowledge becomes concentrated in capital; the worker becomes a detail labourer.

  Machinery takes this further. The tool passes out of the worker's hands into a mechanism. The worker becomes an appendage to an automatic system. Machinery cheapens commodities and therefore cheapens labour power, which is one reason capitalists introduce it. But it also disciplines the workforce, suppresses resistance, and can extend the working day by allowing the capitalist to recoup the machine's value before it becomes obsolete.

  Moishe Postone described the long-run dynamic as a "treadmill effect". Higher productivity increases the material wealth produced per hour, but because value remains tied to the abstract labour time expended, the value per unit falls. This forces capitalists to keep increasing productivity just to maintain the same value creation, producing a permanent acceleration.

  Accumulation over time changes the composition of capital. Capitalists invest more in machinery and raw materials relative to wage labour. Marx called this a rising organic composition of capital. Because only living labour produces surplus value, a rising ratio of machinery to labour tends to depress the general rate of profit, even as individual productivity climbs. Marx presented this tendency of the rate of profit to fall as "the most important law of modern political economy", while also identifying counteracting forces: raising the intensity of exploitation, depressing wages below the value of labour power, cheapening the elements of constant capital, and opening foreign trade.

  Rising accumulation also produces what Marx called the industrial reserve army, a pool of unemployed workers generated by the very process of mechanisation. This reserve army keeps wages under downward pressure, disciplines the employed, and stands ready to be drawn back into production when expansion demands it. Wendy Brown, drawing on Marx, described capital's dynamic as an "almighty shredder of all life forms and practices".

• 6. Circulation, Credit, and Crisis

  ›

  Volume II, assembled by Engels from multiple drafts and published in 1885, shifts the frame from the factory floor to the flows of money and commodities through the economy. Marx's question here is how the value and surplus value produced in production are realised in sale, and what happens when that realisation runs into trouble.

  Industrial capital passes through three functional circuits. In the circuit of money capital, money buys labour power and means of production, production creates new commodities with surplus value embedded in them, and those commodities are sold for a greater sum of money. The circuit of productive capital begins and ends with capital in its productive form. The circuit of commodity capital highlights the aggregate flow of goods through the economy. These are not three types of capital but three forms that the same capital successively assumes.

  Time is a central concern. Reducing circulation time, the period spent buying and selling rather than producing, speeds up the turnover of capital and increases the annual mass of surplus value. The development of transport and communications directly shortens this time. The credit system allows capitalists to bridge gaps and mismatches between different turnover periods.

  Marx divides the total economy into two departments: Department I produces means of production, and Department II produces means of consumption. For simple reproduction, the constant capital used up in Department II must equal the variable capital and surplus value generated in Department I. For expanded reproduction, portions of surplus value in both departments must be reinvested. Marx demonstrated arithmetically how balanced growth is theoretically possible, but he also traced the many points where disproportionalities and crises can emerge.

  The credit system, which Marx largely abstracted from in Volume II, introduces its own instabilities. Volume III, published by Engels in 1894, traces how credit becomes essential to capital accumulation and how it creates fictitious capital: titles to future revenue in the form of government bonds and company shares whose market price can fluctuate independently of the real capital they represent. Speculation fuelled by fictitious capital intensifies crises rather than preventing them. Marx critiqued the Bank Act of 1844 in Britain, arguing that such legislation cannot abolish crises, which arise from contradictions inherent in capitalism itself. "The ultimate reason for all real crises", Marx wrote, "always remains the poverty and restricted consumption of the masses, in the face of the drive of capitalist production to develop the productive forces as if only the absolute consumption capacity of society set a limit to them."

• 7. Writing a Masterpiece in Fragments

  ›

  In February 1867, shortly before delivering his manuscript to the printer, Marx wrote to Engels urging him to read Honore de Balzac's The Unknown Masterpiece, the story of a painter who reworks his canvas endlessly until nothing remains. Marx saw in that story a mirror of his own struggle.

  The writing of Capital had taken decades. Marx's Economic and Philosophic Manuscripts of 1844 represent an early, rough draft of ideas that would mature into the finished work. The Grundrisse, a lengthy manuscript written in 1857-1858 and described as a "first draft" of Capital, contains extensive discussions of alienation, dialectics, and the theory of value. Unlike the polished final text, the Grundrisse reveals the "chisel marks" of Marx's method; for example, the word "labour" is used there to cover both the worker's capacity to labour and the activity itself, a distinction he later clarified with the precise concept of labour power.

  A preliminary version, A Contribution to the Critique of Political Economy, was published in 1859 but covered only a fraction of the planned work and received little attention. Marx kept revising, driven by new research and by events such as the American Civil War and the rise of the International Working Men's Association, of which he became a leading figure. He saw Capital as a vital tool for the workers' movement, and the political work of the International and the intellectual project of the book were, in his own account, intertwined.

  Marx's original plan, drawn up in 1857, was much broader than what was published: six books covering capital, landed property, wage-labour, the state, international trade, and the world market and crises. By 1865-66, the structure had been revised to four volumes on capital. The three published volumes correspond only to the first book of that abandoned six-book plan.

  When Volume I was published in September 1867 by Otto Meissner in Hamburg, its initial reception was muted. Engels responded by submitting pseudonymous hostile reviews to German newspapers to generate discussion, and urged Marx's friends to talk about the book "over and over again, in any way whatsoever". It took four years for the first edition of 1,000 copies to sell out. A revised second German edition was published in instalments from 1872 to 1873, the last version Marx personally revised and authorised. He died in 1883 without completing the manuscripts for Volumes II and III, leaving Engels the enormous task of constructing coherent texts from what were often fragmentary, disorganised, and multiply drafted pages.
