I
Start with the paper of 1945, The Use of Knowledge in Society.
Twenty pages, and they are the key to his whole position.
He asks the question that lies underneath all the others: to run a large economy, where is the knowledge that would be required?
Nowhere in particular, he answers. It is scattered through the small days of millions of people. This wagon-load of tin sitting in the yard behind that workshop. This fitter's hand is two microns steadier than the next man's. That mountain road takes twenty minutes longer when it rains. This old customer always pays three weeks late.
Most of it cannot be written down. It is feel, it is local, it is of the moment and gone again. Put it into a memorandum and it stiffens and dies, and is no longer the thing it was.
So the man who means to sit in an office and direct the whole lacks neither power nor good faith. He lacks the material. The complete ledger he wants has never, as a matter of logic, existed.
Then what is a price for?
A price is a compressor. It takes those millions of small shifting facts, presses them into a single number, and hands it to a stranger.
The tin buyer in New York need not know what happened at the mines in Malaya. He needs only to see that tin has risen, and use a little less.
II
The weight of the paper is that it is not a political claim, nor even an economic one. It is a claim about how a person knows.
It and Popper's work are mirrors of each other.
Popper, in the philosophy of science: no theory is ever finally verified; we can only keep testing, and stay open.
Hayek, in economics: no one man holds the material; we can only rely on the market, and stay spontaneous.
One starts from science and one from economics, and they arrive at the same riverbank — because human ignorance is real, power must be watched institutionally.
And they were friends. It was Hayek who ran about under the war clouds getting Popper into the London School of Economics. Their letters run across half a century.
III
In 1974 Hayek took the Nobel. The lecture was called The Pretence of Knowledge.
He stood in the lights and said something very close to overturning the table: that economics, to look like a hard science, dresses itself desperately as physics, and that the prize merely lends economics the dignity of physics.
His meaning was that the prize itself feeds a danger — it lets economists believe they know everything.
A man saying, on the day he takes the highest honour of his trade, that the honour carries poison.
That is very hard. Most scholars could not do it in a lifetime.
IV
Now the other thing, and it is not comprehensible.
In 1977 he went to Chile, and again in 1981. Pinochet held the country. Under the boots of that government lay some thousands secretly executed or disappeared.
In the summer of 1978 he wrote four public letters in succession to The Times of London, defending the regime with a Nobel laureate's pen.
In 1981 he said this to El Mercurio in Santiago:
I prefer a liberal dictator to democratic government lacking liberalism.
V
The worst of it is not the sentence. It is that he had written the verdict on such men twenty years earlier, in his own hand.
In 1960 The Constitution of Liberty appeared with a long postscript titled Why I Am Not a Conservative.
There he laid the weakness of conservatism open. Its decisive fault, he said, is that by its very nature it cannot offer an alternative to the direction in which we are moving. It can slow things down; it cannot point anywhere.
And he named something worse. The conservative, like the socialist, is willing to coerce others in the service of ends he judges good. Not trusting spontaneous order, he turns the moment he is frightened to the strong hand of government — provided that hand is on his side, and provided it promises to hold down the enemy he fears.
That was the early Hayek, standing on high ground, looking coldly at men who hand over their souls to a dictator for the sake of order.
An aside. What I admire in Hayek is not chiefly The Road to Serfdom, the book everyone knows. I do not fully accept his case for an entirely free market — a country that means to stay competitive needs some coordination. Whether to send the whole of manufacturing offshore, whether to hold a national plan for advanced technology and artificial intelligence: those remain open questions.
What I like is Why I Am Not a Conservative.
He cannot have imagined that twenty years later he would become the man in his own essay. Facing Allende's socialist experiment, he was frightened. To put out the devil he saw, he turned and walked into the arms of a worse one.
VI
Take the sentence apart. When you do, what collapses is the building he spent a life putting up.
Liberal there is not the word an American uses now. It is classical liberalism: private property, markets, and the one he argued for across book after book and held dearer than his life — the rule of law.
And in his definition the rule of law is not the loose sense of there being laws to go by. His requirement is close to fastidious: rules must be general, abstract, published in advance, applied to everyone alike, and never aimed at a particular person.
Why so strict? Because only when rules are transparent and cannot be altered at will can a weak man predict how the state will treat him tomorrow, and dare to arrange his one life accordingly.
Now put the secret police into the conditions he wrote himself.
A knock in the night. No warrant. No charge stated. The person is taken. After that, nothing.
That tramples every clause without exception. There is nothing on earth less predictable than the whim of a dictator.
Pinochet's Chile had markets driven in by force and property guarded by bayonets. The one thing it did not have was the rule of law he had spent his life defending.
So the sentence is not his theory running into a hard case. It is his own hand swapping out his own core: he put there are markets where there is rule of law had stood. In his own books those were never one thing.
VII
He offered a further defence. He said he had asked people in Chile and found none who felt less free than under Allende.
That is the ugliest part, and there is something cruel in it.
Conducting a street survey in a country where one wrong sentence makes a family disappear, and then producing what he was told as evidence.
The man who wrote The Use of Knowledge in Society should have known before anyone alive that here the signal was contaminated at the source, by the bayonet.
That was his own trade. He behaved as though he could not see it.
VIII
There is one more sentence to measure him by. Coleridge wrote it in 1825:
He who begins by loving Christianity better than Truth, will proceed by loving his own sect or church better than Christianity, and end in loving himself better than all.
That sentence hands you no judgement. It hands you an order. An order can be checked.
Now change a few words.
The market is a means. Liberty is the end. The market matters because it protects a particular person — his choices, his property, his body.
He who begins by loving the market better than liberty will proceed by loving his own programme better than the market, and end by loving the strong man who will impose that programme better than liberty itself.
I do not have to infer those three steps. His sentence of 1981 states the order outright: markets first, the ballot second. He ranked them himself.
And the road belongs to no one side.
He who begins by loving equality as an abstract proposition better than living people will proceed by loving his party better than equality, and end by loving the man who holds the party better than all.
Pinochet stands at one end and Stalin at the other. The walk is the same: take a means, set it up as the highest thing, and then kill for it the very person it existed to protect.
IX
So the conclusion is not that the paper is bad. The paper remains great, and we still use it as a tool.
The conclusion is this.
The thing a man forges with his own hands and gives to the world is the one he is least willing, and least able, to turn on himself.
Hayek said all his life that nobody holds the whole, and that therefore every arrangement must leave a road by which error can be corrected.
By 1981, facing a man who had blocked every such road, he said he would rather have that one.
His old friend Popper had already set it down plainly in The Open Society and Its Enemies: a society that leaves no circuit for correcting error is a closed one, however fine the blueprint it announces. The Book of Popper 5.11 is the same sentence: what does not leave that road is closed, however good it says it is.
The man who wrote it had been his friend for decades.
