Friedrich Hayek is one of the seminal thinkers within conservatism and his having once been a socialist adds depth to his thinking.
His relationship with John Maynard Keynes is interesting and noted in this left-leaning article from the New Statesman.
There can be no doubt that his encounter with Keynes was the most important event in his intellectual life. Yet he had little insight into Keynes either as a thinker or a human being. He told me that during their acquaintance he never realised that Keynes had been homosexual – a surprising admission, as it was hardly something Keynes concealed within his circle of friends. The two men had quite different kinds of minds – Keynes’s swift and mobile, with an almost clairvoyant power of entering into the thinking of others; Hayek’s slowly probing, inwardly turned and self-enclosed. They were nonetheless on cordial terms.
Keynes found Hayek rooms in King’s College when the London School of Economics (where Hayek became a professor of economics in 1931) moved to Cambridge for the duration of the Second World War, and for a time the pair shared fire-watching duties on the roof of the college when it was feared that Cambridge might be bombed. With characteristic generosity, Keynes – while firmly rejecting its claim that government management of the economy is bound to lead to totalitarianism – heaped praise on Hayek’s anti-socialist tract The Road to Serfdom when it appeared in 1944.
The differences between the two thinkers were as much in their underlying philosophies as in their economic theories. Both were sharply aware of the limits of human knowledge. But whereas Hayek invoked these limits to argue for non-intervention in the economy, Keynes recognised that bold action by governments is sometimes the only way in which the economy can be lifted out of depression – as when Roosevelt (to whom Keynes had written an open letter in 1933) successfully adopted some aspects of Keynesian thinking in the New Deal.
Hayek was most original when he argued that the market is a means of discovering and transmitting information that is dispersed throughout society. It was this insight into the knowledge-creating function of markets that enabled him to formulate a decisive argument against central economic planning.
Generations of socialists have maintained that the failings of the Soviet economy were because of historical causes extraneous to the planning system: a lack of democracy rooted in tsarist traditions of despotism, the underdevelopment of the Russian economy when the Soviet system came into being, and Stalin’s deformation of Lenin’s supposedly more benign inheritance.
As Hayek perceived, none of these factors can account for the universal failings of planned economies, which have followed a similar pattern in countries as different as Czechoslovakia and Mongolia, East Germany and Cuba. The fundamental reason for the failures of central economic planning is that economic knowledge cannot be centralised. More than the love of power or the inevitability of corruption, it is the limitations of human knowledge that make socialist planning an impossible dream. Here Hayek’s argument was unanswerable.
If they had been adopted while the crash was under way, Hayek’s prescriptions would have made the Depression even worse than it proved to be – a fact he later admitted. But he never accepted Keynes’s core insight that large-scale economic discoordination could be the result of the workings of the market itself. For him it was always government intervention that accounted for market disequilibrium. More sceptical as well as more radical in his turn of mind, Keynes questioned the self-regulating powers of the market. His work on the theory of probability disclosed insuperable gaps in our knowledge of the future; all investment was a gamble, and markets could not be relied on to allocate capital rightly. There were booms and busts long before the emergence of modern central banking. Left to its own devices, the free market can easily end up in a dead end like that of the 1930s.
