Capital

Overview

Almost everyone who says they have read Capital has read Volume I, and that is the right thing to read. It is the only volume Marx finished and published, in 1867, after two decades in the British Museum reading room. Volumes II and III were assembled by Engels from manuscripts after Marx’s death and handle the circulation of capital and the rate of profit; they are for specialists.

Volume I has eight parts and thirty-three chapters, and it changes register repeatedly. The first three chapters are abstract to the point of difficulty, working out the concepts of value, money and exchange in a style Marx borrowed from Hegel. Then, around chapter 7, the book turns into something else: a documentary account of English industry built out of factory inspectors’ reports, parliamentary Blue Books, medical officers’ findings and newspaper advertisements. The chapter on the working day quotes the hours of child labour in lace mills. The chapter on machinery describes what happens to hand weavers. The last part, on primitive accumulation, is narrative history about sheep, enclosures and vagrancy law.

Marx wrote it as a critique of political economy, meaning a critique from inside. He accepts most of Ricardo’s apparatus and then shows, he believes, that the apparatus implies things its owners would rather not admit.

The argument

Begin with the commodity, something made to be exchanged. It has a use, and it has an exchange value, a rate at which it trades for other things. Since a coat and a quantity of grain are useful in incommensurable ways, whatever makes them exchangeable at a ratio must be something else they share, and Marx says it is the socially necessary labour time embodied in them. Value is congealed labour; money is the commodity that comes to express everyone’s value.

Now the puzzle. Exchange of equivalents cannot create value: if you trade a thing worth ten for a thing worth ten, no one gains. Yet capitalists systematically end a cycle with more money than they started with. Buying cheap and selling dear explains one merchant’s gain at another’s expense, not a general profit. So there must be a commodity whose consumption produces more value than it costs, and there is: labour power, the capacity to work. The worker sells a day’s capacity at its value, which is what it costs to keep him alive and able to return. He then works a full day. If the value he produces in four hours covers his wage, the rest of the day yields surplus value to the buyer. No cheating is required. The transaction is a fair one and the result is systematic appropriation.

Everything else in the volume develops this. Absolute surplus value comes from lengthening the working day, which is why the fight over hours is central and why Marx spends a hundred pages on it. Relative surplus value comes from raising productivity so that the worker’s necessary time shrinks, which is why capital is compelled to mechanise. Machinery, on this account, is not neutral: it disciplines labour, deskills it, draws in women and children, and creates the reserve of the unemployed that keeps wages down. Chapter 25 sets out the general law of accumulation, in which capital concentrates and the surplus population grows alongside the wealth.

Then Marx asks where the whole arrangement came from, since it requires a mass of people with nothing to sell but themselves. Part Eight answers with history: the expropriation of English peasants from common land, the destruction of household production, colonial plunder, and the state’s use of criminal law to force the dispossessed into wage work. The system was not the outcome of thrift. It was made.

Alongside the economics runs an argument about perception. Under commodity production, relations between people appear as relations between things, so that the market looks like a natural order with laws of its own. Marx calls this fetishism, and it is his explanation for why political economy mistook a historical arrangement for the nature of things.

How to read it

Courses usually assign parts of it, and the standard route is: chapter 1 sections 1 and 4, chapter 4, chapters 6 and 7, chapter 10, chapters 14 and 15 in extract, chapter 25, and chapters 26 through 32. That gives you the theory of value, the derivation of surplus value, the working day, machinery, accumulation and the historical origin.

Do not get stuck in chapter 1. It is the hardest thing in the book, and generations of readers have foundered on the form of value and the equivalent form. Read it once, accept that some of it is opaque, go on, and come back after chapter 10, when you know what the concepts are for.

Read the factory chapters as evidence, not illustration. Marx thought the case rested on them. They also explain the tone: the sarcasm is aimed at economists who described this and called it freedom of contract.

Watch what Marx does not say. There is no blueprint for socialism here, almost no discussion of revolution, and no claim that capitalists are wicked individuals. The argument is structural, which is what makes it harder to answer.

On translations: Fowkes is the scholarly standard in English. Moore and Aveling, supervised by Engels, is free and perfectly usable, which is why its wording is the one most often quoted. The 2024 Princeton version is the freshest and the most heavily annotated.

Questions it raises

• The whole argument rests on the labour theory of value. If value is set by supply and demand instead, what survives?
• Marx insists the wage bargain is an exchange of equivalents. Why is the result still an injustice, and by what standard?
• If machinery raises productivity, why should real wages not rise with it? What in the model prevents that?
• Is commodity fetishism a claim about ideology, about perception, or about the structure of exchange itself?
• The last part argues that capitalism was founded in force. Does its origin bear on whether it is justified now?
• Marx describes concentration, crisis and a growing surplus population as laws. Are they predictions, tendencies, or descriptions of Victorian England?
