Summary
Marx tackles capitalism's central mystery: if everyone trades fairly, where does profit come from? He methodically dismantles popular explanations that blame profit on cheating or clever trading. When A sells wine to B for more than it's worth, B loses exactly what A gains—no new wealth appears. Even if everyone could sell above value, they'd all pay higher prices too, canceling out any advantage. Marx shows this applies whether we're talking about merchants, moneylenders, or any trader. The math is ruthless: fair exchanges create no surplus value, and unfair ones just shuffle existing wealth around. Yet capitalism clearly does create new wealth somehow. This contradiction forces Marx to a crucial insight—profit must come from somewhere else entirely, not from the act of buying and selling itself. He's eliminated the obvious answers, setting up the real question: if circulation can't create surplus value, and isolated production can't either, then surplus value must emerge from some special circumstance that exists both within circulation and outside it. The chapter ends with this riddle hanging in the air, demanding a solution that will reshape how we understand the entire economic system.
Coming Up in Chapter 6
Marx has ruled out trading tricks as the source of profit. Now he must solve the puzzle: what special commodity, when bought and sold fairly, can still create more value than it costs? The answer will reveal capitalism's deepest secret.

CONTRADICTIONS IN THE GENERAL FORMULA OF CAPITAL Economic Manuscripts: Capital Vol. I - Chapter Five Karl Marx. Capital Volume One Chapter Five: Contradictions in the General Formula of Capital The form which circulation takes when money becomes capital, is opposed to all the laws we have hitherto investigated bearing on the nature of commodities, value and money, and even of circulation itself. What distinguishes this form from that of the simple circulation of commodities, is the inverted order of succession of the two antithetical processes, sale and purchase. How can this purely formal distinction between these processes change their character as it were by magic? But that is not all. This inversion has no existence for two out of the three persons who transact business together. As capitalist, I buy commodities from A and sell them again to B, but as a simple owner of commodities, I sell them to B and then purchase fresh ones from A. A and B see no difference between the two sets of transactions. They are merely buyers or sellers. And I on each occasion meet them as a mere owner of either money or commodities, as a buyer or a seller, and, what is more, in both sets of transactions, I am opposed to A only as a buyer and to B only as a seller, to the one only as money, to the other only as commodities, and to neither of them as capital or a capitalist, or as representative of anything that is more than money or commodities, or that can produce any effect beyond what money and commodities can. For me the purchase from A and the sale to B are part of a series. But the connexion between the two acts exists for me alone. A does not trouble himself about my transaction with B, nor does B about my business with A. And if I offered to explain to them the meritorious nature of my action in inverting the order of succession, they would probably point out to me that I was mistaken as to that order of succession, and that the whole transaction, instead of beginning with a purchase and ending with a sale, began, on the contrary, with a sale and was concluded with a purchase. In truth, my first act, the purchase, was from the standpoint of A, a sale, and my second act, the sale, was from the standpoint of B, a purchase. Not content with that, A and B would declare that the whole series was superfluous and nothing but Hokus Pokus; that for the future A would buy direct from B, and B sell direct to A. Thus the whole transaction would be reduced to a single act forming an isolated, non-complemented phase in the ordinary circulation of commodities, a mere sale from A’s point of view, and from B’s, a mere purchase. The inversion, therefore, of the order of succession, does not take us outside the sphere of the simple circulation...

The Road of Hidden Sources - Why Problems Never Come From Where They Seem To
Real problems rarely originate from their most visible symptoms, but from hidden structural forces that benefit from the problem's continuation.
Why This Matters
Connect literature to life
This chapter teaches systematic elimination of surface explanations to find hidden profit sources.
Practice This Today
Next time everyone's blaming each other for a shared problem, ask: 'If we fixed this obvious cause, would the underlying issue actually disappear?'
Now let's explore the literary elements.
Terms to Know
Surplus Value
The extra wealth that somehow appears in capitalism beyond what was originally invested. Marx's central mystery: if everyone trades fairly, where does this additional value come from?
Modern Usage:
When a company pays workers $15/hour but sells their work for $50/hour, that $35 difference is surplus value.
Circulation
The process of buying and selling goods in the marketplace. Marx argues this exchange process alone cannot create new wealth, only move existing wealth around.
Modern Usage:
When you buy something on Amazon and resell it on eBay, you're participating in circulation - moving goods but not creating new value.
General Formula of Capital
Marx's way of describing how capitalism works: Money → Commodities → More Money. The puzzle is explaining where that 'More Money' comes from.
Modern Usage:
Any business investment follows this pattern - you spend money to make more money, but the source of that extra money needs explaining.
Use Value vs Exchange Value
Use value is what something is actually good for; exchange value is what you can trade it for. Marx shows these are completely different things.
Modern Usage:
A designer handbag might have little use value but huge exchange value, while a generic bag does the job better but sells for less.
Commodity
Anything produced specifically to be sold rather than used by the maker. Under capitalism, even human labor becomes a commodity to be bought and sold.
Modern Usage:
Your time at work is a commodity you sell to your employer - they buy your labor power, not you as a person.
Contradiction
When the logic of a system works against itself. Marx identifies capitalism's core contradiction: it needs fair exchange but also needs to generate profit.
Modern Usage:
Companies want loyal workers but also want to cut labor costs - these goals contradict each other and create workplace tension.
Characters in This Chapter
A
Seller in the exchange
Represents one side of every market transaction. Marx uses A to show that from the individual trader's perspective, they're just buying or selling normally, unaware of capitalism's larger machinery.
Modern Equivalent:
The person selling you something on Facebook Marketplace
B
Buyer in the exchange
The other side of the transaction who, like A, sees only a normal purchase. Marx demonstrates that neither A nor B can see the capitalist process happening around them.
Modern Equivalent:
The customer at checkout who just wants their stuff
The Capitalist
The invisible orchestrator
The figure who buys from A and sells to B, appearing as just another trader but actually extracting surplus value. Marx shows how capitalists hide their true function behind ordinary-looking exchanges.
Modern Equivalent:
The middleman who buys wholesale and sells retail, claiming they're just providing convenience
Key Quotes & Analysis
"The circulation of commodities is the starting-point of capital."
Context: Marx establishes that capitalism grows out of simple market exchange but becomes something entirely different.
This quote signals that Marx isn't attacking markets themselves, but showing how capitalism transforms normal trading into a system of exploitation. It's a crucial distinction for understanding his argument.
In Today's Words:
Capitalism started with people just buying and selling stuff, but it turned into something much bigger and more problematic.
"No one can sell unless someone else purchases."
Context: Marx demonstrates the logical impossibility of everyone profiting from exchange alone.
This simple observation destroys the myth that profit comes from being a smart trader. If everyone could sell high, everyone would also have to buy high, canceling out any advantage.
In Today's Words:
You can't have winners without losers - if everyone's getting rich from trading, nobody actually is.
"The capitalist must buy his commodities at their value, must sell them at their value, and yet at the end of the process must withdraw more value from circulation than he threw into it at starting."
Context: Marx poses the central riddle that the rest of Capital will solve.
This is the heart of Marx's challenge to economic theory. He's not claiming capitalists cheat, but asking how they can play fair and still make profit. This contradiction demands a new explanation.
In Today's Words:
Business owners have to pay fair prices and charge fair prices, but somehow still make money - how is that even possible?

Critical Thinking Exercise
Follow the Money Trail
Pick a persistent problem in your life where the obvious solution hasn't worked. Use Marx's elimination method: list three surface explanations everyone blames, then ask who might actually benefit from this problem continuing. Map out where resources, attention, or power flow when the problem exists versus when it's solved.
Consider:
- •Look for hidden beneficiaries who gain when the obvious solution fails
- •Consider what systems or structures would need to change for real resolution
- •Ask whether fixing the surface cause would actually eliminate the underlying incentive
Journaling Prompt
Write about a time when you discovered that what everyone said was causing a problem wasn't actually the real source. How did finding the true cause change your approach to solving it?
