A thinker for our times

Global leaders are once again reminding themselves of the insights of the Cambridge academic who hel

John Maynard Keynes has been restored to life. Rusty Keynesian tools – larger budget deficits, tax cuts, accelerated spending programmes and other “economic stimuli” – have been brought back into use the world over to cut off the slide into depression. And they will do the job, if not next year, the year after. But the first Keynesian revolution was not about a rescue operation. Its purpose was to explain how shipwreck might occur; in short, to provide a theoretical basis for better navigation and for steering in seas that were bound to be choppy. Yet, even while the rescue operation is going on, we need to look critically at the economic theory that takes his name.

In his great work The General Theory of Employment, In terest and Money, written during the Great Depression of the 1930s, Keynes said of his ideas that they were "extremely simple, and should be obvious". Market economies were in herently volatile, owing to un certainty about future events being inescapable. Booms were liable to lead to catastrophic collapses followed by long periods of stagnation. Governments had a vital role to play in stabilising market economies. If they did not, the undoubted benefit of markets would be lost and political space would open up for extremists who would offer to solve economic problems by abolishing both markets and liberty. This, in a nutshell, was the Keynesian "political economy".

These ideas were a challenge to the dominant economic models of the day which held that, in the absence of noxious government interference, market economies were naturally stable at full employment. Trading in all markets would always take place at the "right" prices – prices that would "clear the market". This being so, booms and slumps, and prolonged unemployment, could not be generated by the market system itself. If they did happen, it was due to "external shocks". There were many attempts to explain the Great Depression of the 1930s along these lines – as a result of the dislocations of the First World War, of the growth of trade union power to prevent wages falling, and so on. But Keynes rightly regarded such explanations as self-serving. The Great Depression started in the United States, not in war-torn Europe, and in the most lightly regulated, most self-contained, and least unionised, market economy of the world. What were the "external shocks" that caused the Dow Jones Index to fall from 1,000 to 40 between 1929 and 1932, American output to drop by 20 per cent and unemployment to rise to 25 million?

He set out to save capitalism, a system he did not much admire, because he thought it the best hope for the future of civilisation

We can ask exactly the same question today as the world economy slides downwards. The present economic crisis has been generated by a banking system that had been extensively deregulated and in a flexible, largely non-unionised, economy. Indeed, the American capitalism of the past 15 years strongly resembles the capitalism of the 1920s in general character. To Keynes, it seemed obvious that large instabilities were inherent in market processes themselves.


John Maynard Keynes was a product of Cambridge civilisation at its most fertile. He was born in 1883 into an academic family, and his circle included not just the most famous philosophers of the day – G E Moore, Bertrand Russell and Ludwig Wittgenstein – but also that exotic offshoot of Cambridge, the Bloomsbury Group, a commune of writers and painters with whom he formed his closest friendships. Keynes was caught up in the intellectual ferment and sexual awakening that marked the passage from Victorian to Edwardian England. At the same time, he had a highly practical bent: he was a supreme example of what Alasdair MacIntyre calls “the aesthete manager”, who partitions his life between the pleasures of the mind and the senses and the management of public affairs. After the First World War, Keynes set out to save a capitalist system he did not particularly admire. He did so because he thought it was the best guarantor of the possibility of civilisation. But he was always quite clear that the pursuit of wealth was a means, not an end. He did not much admire economics, either, hoping that some day economists would become as useful as dentists.

All of this made him, as his wife put it, "more than an economist". In fact, he was the most brilliant non-economist who ever applied himself to the study of economics. In this lay both his greatness and his vulnerability. He imposed himself on his profession by a series of profound insights into human behaviour which fitted the turbulence of his times. But these were never – could never be – properly integrated into the core of his discipline, which spewed them out as soon as it conveniently could. He died of heart failure in 1946, having worked himself to death in the service of his country.

The economic theory of Keynes's day, which precluded boom-bust sequences, seemed patently contrary to experience, yet its foundations were so deep-dug, its defences so secure, its reasoning so compelling, that it took Keynes three big books – including a two-volume Treatise on Money – to see how it might be cracked. His attempt to do so was the most heroic intellectual enterprise of the 20th century. It was nothing less than the attempt to overturn the dominant economic paradigm dating from Adam Smith and David Ricardo.

He finally said what he wanted to say in the preface to The General Theory: "A monetary economy, we shall find, is one in which changing views about the future are capable of in fluencing the quantity of employment and not merely its direction." In that pregnant sentence is the whole of the Keynesian revolution.

Keynes's understanding about how economies work was rooted in his theory of knowledge. The future was unknowable: so disaster was always possible. Keynes did not believe that the future was wholly unknowable. Not only can we calculate the probability of winning the Lottery, but we can forecast with tolerable accuracy the price movements of consumer goods over a short period. Yet we "simply do not know" what the price of oil will be in ten, or even five, years' time. Investments which promised returns "at a comparatively distant, and sometimes an indefinitely distant, date" were acts of faith, gambles on the unknown. And in that fact lay the possibility of huge mistakes.

Classical economists could not deny the possibility of unpredictable events. Inventions are by their nature unpredictable, especially as to timing, and many business cycle theorists saw them as generating boom-bust cycles. But mainstream economics, nevertheless, "abstracted" from such disturbances. The technique by which it did so is fascinatingly brought out in an argument about economic method between two 19th-century economists, which Keynes cited as a fork in the road. In 1817, Ricardo wrote to his friend Thomas Malthus: "It appears to me that one great cause of our differences . . . is that you have always in your mind the immediate and temporary effects of particular changes, whereas I put these immediate and temporary effects quite aside, and fix my whole attention on the permanent state of things which will result from them."

To this, Malthus replied: "I certainly am disposed to refer frequently to things as they are, as the only way of making one's writing practically useful to society . . . Besides I really do think that the progress of society consists of irregular movements, and that to omit the consideration of causes which for eight or ten years will give a great stimulus to production and population or a great check to them is to omit the causes of the wealth and poverty of nations . . ."

Keynes sided with Malthus. He regarded the timeless equilibrium method pioneered by Ricardo as the great wrong turning in economics. It was surely the Ricardo-Malthus exchange he had in mind when writing his best-known aphorism: "But this long run is a misleading guide to affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task if in tempestuous seasons they can only tell us that when the storm is long past the ocean is flat again."

Ricardo may have thought of the "long run" as the length of time it took storms to disperse. But under the influence of mathematics, economists abandoned the notion of time itself, and therefore of the distinction between the long run and the short run. By Keynes's time, "risks", as he put it, "were supposed to be capable of an exact actuarial computation". If all risks could be measured they could be known in advance. So the future could be reduced to the same epistemological status as the present. Prices would always reflect objective probabilities. This amounted to saying that unregulated market economies would generally be extremely stable. Only very clever people, equipped with adequate mathematics, could believe in anything quite so absurd. Under the influence of this theory, governments withdrew from active management and regulation of economic life: it was the age of laissez-faire.

Keynes commented: "The extraordinary achievement of the classical theory was to overcome the beliefs of the 'natural man' and, at the same time, to be wrong." It was wrong because it "attempts to apply highly precise and mathematical methods to material which is itself much too vague to support such treatment".

Keynes did not believe that "natural man" was irrational. The question he asked was: how do we, as rational investors, behave when we – unlike economists – know that the future is uncertain, or, in economist-speak, know that we are "informationally deprived"? His answer was that we adopt certain "conventions": we assume that the future will be more like the past than experience would justify, that existing opinion as expressed in current prices correctly sums up future prospects, and we copy what everyone else is doing. (As he once put it: "Bankers prefer to be ruined in a conventional way.") But any view of the future based on "so flimsy a foundation" is liable to "sudden and violent changes" when the news changes. "The practice of calmness and immobility, of certainty and security suddenly breaks down. New fears and hopes will, without warning, take charge of human conduct . . . the market will be subject to waves of optimistic and pessimistic sentiment, which are unreasoning yet in a sense legitimate where no solid basis exists for a reasonable calculation."


But what is rational for individuals is catastrophic for the economy. Subnormal activity is possible because, in times of crisis, money carries a liquidity premium. This increased "propensity to hoard" is decisive in preventing a quick enough fall in interest rates. The mainstream economics of Keynes's day viewed the interest rate (more accurately, the structure of interest rates) as the price that balances the overall supply of saving with the demand for investment. If the desire to save more went up, interest rates would automatically fall; if the desire to save fell, they would rise. This continual balancing act was what made the market economy self-adjusting. Keynes, on the other hand, saw the interest rate as the "premium" for parting with money. Pessimistic views of the future would raise the price for parting with money, even though the supply of saving was increasing and the demand for investment was falling. Keynes's "liquidity preference theory of the rate of interest" was the main reason he gave for his claim that market economies were not automatically self-correcting. Uncertainty was what ruined the classical scheme.

The same uncertainty made monetary policy a dubious agent of recovery. Even a "cheap money" policy by the central bank might not be enough to halt the slide into depression if the public's desire to hoard money was going up at the same time. Even if you provide the water, you can't force a horse to drink. This was Keynes's main argument for the use of fiscal policy to fight a depression. There is only one sure way to get an increase in spending in the face of falling confidence and that is for the government to spend the money itself.

This, in essence, was the Keynesian revolution. Keynesian economics dominated policymaking in the 25 years or so after the Second World War. The free-market ideologists gave this period such a bad press, that we forget how successful it was. Even slow-growing Britain chugged along at between 2 and 3 per cent per capita income growth from 1950-73 without serious interruptions, and the rest of the world, developed and developing, grew quite a bit faster. But an intellectual/ideological rebellion against Keynesian economics was gathering force. It finally got its chance to restore economics to its old tramlines with the rise of inflation from the late 1960s onwards – something which had less to do with Keynesian policy than with the Vietnam War. The truth was that "scientific" economics could not live with the idea of an unpredictable world. So, rather than admit that it could not be a "hard" science like physics, it set out to abolish uncertainty.

The "new" classical economists hit on a weak spot in Keynesian theory. The view that a large part of the future was unknowable seemed to leave out learning from experience or making efficient use of available information. Rational agents went on making the same mistakes. It seemed more reasonable to assume that recurrent events would initiate a learning process, causing agents to be less often surprised by events. This would make economies more stable.

The attack on Keynes's "uncertain" expectations developed from the 1960s onwards, from the "adaptive" expectations of Milton Friedman to the "rational" expectations of Robert Lucas and others. The development of Bayesian statistics and Bayesian decision-theory suggested that agents can always be modelled as having prior probability distributions over events – distributions that are updated by evidence.


Today, the idea of radical uncertainty, though ardently championed by “post-Keynesians” such as Paul Davidson, has little currency in mainstream economics; however, it is supported by financiers of an intellectual bent such as George Soros. As a result, uncertainty once more became “risk”, and risk can always be managed, measured, hedged and spread. This underlies the “efficient market hypothesis” – the idea that all share options can be correctly priced. Its acceptance explains the explosion of leveraged finance since the 1980s. The efficient market hypothesis has a further implication. If the market always prices financial assets correctly, the “real” economy – the one involved in the production of goods and non-financial services – will be as stable as the financial sector. Keynes’s idea that “changing views about the future are capable of influencing the quantity of employment” became a discarded heresy.

And yet the questions remain. Is the present crisis a once-in-a-lifetime event, against which it would be as absurd to guard as an earthquake, or is it an ever-present possibility? Do large "surprises" get instantly diffused through the price system or do their effects linger on like toxic waste, preventing full recovery? There are also questions about the present system that Keynes hardly considered. For instance: are some structures of the economy more conducive to macroeconomic stability than others?

This is the terrain of Karl Marx and the underconsump tionist theorists. There is a long tradition, recently revived, which argues that the more unequal the distribution of income, the more unstable an economy will be. Certainly globalisation has shifted GDP shares from wages to profits. In the underconsumptionist tradition, this leads to overinvestment. The explosion of debt finance can be interpreted as a way of postponing the "crisis of realisation".

Keynes did not have a complete answer to the problems we are facing once again. But, like all great thinkers, he leaves us with ideas which compel us to rethink our situation. In the long run, he deserves to ride again.

Inside the minds of the Isis murderers

As pressure on the terror group who claimed responsiblity for the Manchester attack intensifies, the threat to Britain will only become more acute.

The police and security services had consistently warned that a significant terrorist attack in Britain was inevitable. Yet no warning could have prepared us for the horror of the suicide attack on the Manchester Arena on Monday night. Twenty-two people were killed and at least 60 were wounded as they were leaving a concert by Ariana Grande in what was the most deadly attack in Britain since the London bombings of 7 July 2005, in which 56 people died.

Like the London bombers, the Manchester suicide attacker, Salman Ramadan Abedi, was British. He was 22, lived in Manchester and studied business management at Salford University before dropping out. He worshipped at Didsbury Mosque. The son of Libyans, Abedi is said to have returned recently from a visit to the North African country, where Islamic State has a foothold.

Ariana Grande is a former children’s TV star who made her name on channels such as Nickelodeon. Her fan base is overwhelmingly young and female, and many of those killed or wounded were children, including Saffie Rose Roussos, an eight-year-old girl from Leyland, Lancashire.

Islamic State inevitably claimed responsibility for the massacre, dismissing the victims as “crusaders”, “polytheists” and “worshippers of the cross”. This is not the first time Islamist terrorists have targeted children.

A Chechen jihadist group calling itself ­Riyad-us Saliheen (meaning “Gardens of the Righteous”) took more than 1,100 hostages, including 777 children, in a school siege in Beslan, Russia, in September 2004. In the event, more than 330 were massacred, including 186 children. Gunmen from the Pakistani Taliban also stormed a school in 2014, killing 148.

For terrorist actors, these are neither whimsical nor irrational acts. Contemporary jihadist movements have curated a broad and expansive intellectual ecosystem that rationalises and directs their actions. What they want is to create an asymmetry of fear by employing indiscriminate barbarism to intimidate and subdue their opponents into submission.

We have grown accustomed to a wave of terrorist attacks being carried out in the name of the self-styled Islamic State ever since the group’s official spokesman Abu Muhammad al-Adnani began prioritising them in 2014. (He was killed in an American air strike on Aleppo province in Syria in August last year.)

The US-led coalition against Islamic State has weakened the terror group in its former strongholds of Mosul in Iraq and Raqqa in Syria. In response, IS has been forced to concentrate more on what it calls “external operations” – by which it means inspiring its sympathisers and operatives to carry out attacks on Western countries. Indeed, al-Adnani encouraged the group’s supporters not to migrate towards IS-held territory but rather to focus their efforts on attacks in their home countries.

“The tiniest action you do in the heart of their [Western] land is dearer to us than the biggest action by us,” he said in an audio statement released last year. “There are no innocents in the heart of the lands of the crusaders.”

Islamic State refers to its strategy as “just terror”. Its framing places culpability for attacks on Western states on these nations themselves by claiming that IS actions are a response to aggression or assault. That much has been outlined in the group’s literature. “When will the crusaders end their hostilities towards Islam and the Muslims? . . . When will they recognise that the solution to their pathetic turmoil is right before their blinded eyes?” the militants ask in the IS magazine Dabiq. “Until then, the just terror will continue to strike them to the core of their deadened hearts.”

IS offered a rationale of this sort as justification for its bombing of a Russian commercial aircraft – Metrojet Flight 9268, travelling from Sharm el-Sheikh in Egypt to St Petersburg. That attack in October 2015 killed 224. Similar reasoning was offered for the attacks in Paris the following month in which 137 people were killed, in a series of co-ordinated, commando-style gun and bomb outrages across the city.

“Revenge was exacted upon those who felt safe,” IS declared in Dabiq. “Let the world know that we are living today in a new era. Whoever was heedless must now be alert. Whoever was sleeping must now awaken . . . The [caliphate] will take revenge for any aggression against its religion and people, sooner rather than later. Let the ­arrogant know that the skies and the lands are Allah’s.”


Through my academic research at King’s College London, I have ­interviewed scores of Westerners who became foreign fighters in Syria and Iraq to quiz them about their motives. Last year, one man from High Wycombe who had joined IS told me that it wanted to attack British targets in response to the vote in the House of Commons to extend British air strikes against IS targets to include sites in Syria (the British had only been targeting the group in Iraq until that point). “Do they [the British government] expect us to sit back and do nothing? ­Idiots,” he said.

In this respect, IS frames its attacks as acts of “revenge” and predicates its response on the Islamic principle of qisas, which is comparable to lex talionis or the doctrine of “an eye for an eye”. Qisas was always intended to be a tool of private redress for an individual or his/her family to seek justice in matters relating to bodily harm. Typically, it relates to cases of murder and manslaughter, or acts involving physical mutilation (say, leading to loss of limbs). The principle creates a framework for retributive justice.

The contemporary Salafi-jihadi movement has adopted a particularly innovative approach to the concept of qisas in two ways. First, groups such as IS have taken the idea and construed it in a way that justifies indiscriminate terrorism, such as the attack in Manchester. They argue that qisas has a political dimension and that it can be applied to international affairs in a way that holds civilians responsible for the perceived crimes of their governments.

Second, qisas is normally applied only in cases where the aggressor is known. IS, by contrast, holds every citizen-stranger of an enemy state responsible for the actions of his or her government. Thus, when it released its statement claiming responsibility for the Manchester attack, it said that it had struck against a “gathering of the crusaders . . . in response to their transgressions against the lands of the Muslims”.

It is this militaristic construction of qisas that allows IS to rationalise the bombing of a venue where large numbers of young girls had gathered to watch a pop concert, dismissing them as “crusaders”.

This is not new. In 1997, Osama Bin Laden told CBS News that “all Americans are our enemies, not just the ones who fight us directly, but also the ones who pay their ­taxes”. His rationale was that all Americans, by virtue of citizenship alone, are vicariously liable for the actions of their government.

Just a few years later, Bin Laden used the same idea to justify the 11 September 2001 attacks and also invoked it in reference to the Israeli-Palestinian conflict. “The blood pouring out of Palestine must be equally revenged,” he wrote. “You must know that the Palestinians do not cry alone; their women are not widowed alone; their sons are not orphaned alone.”

IS used the concept most dramatically in January 2015, when it burned alive a Royal Jordanian Air Force pilot, Muath al-Kasasbeh, whose plane had crashed in its territory. A video of the killing was circulated on the internet and social media. The group claimed his bombing raids had killed civilians and that it wanted to punish him with “equal retaliation”, in keeping with qisas.

What is well known about al-Kasasbeh’s murder is that he was burned alive inside a cage – but that is not the whole story. To understand how IS tethered this to the principle of qisas, it is the end of the gruesome video that is invested with most significance. After al-Kasasbeh has died, a truck emerges and dumps rubble over the cage. It was claimed this was debris from a site he had bombed, thus completing the “equal retaliation” of returning like for like. The idea was that IS had retaliated using the two principal forms in which a missile attack kills – by fire or debris.


The Manchester attack came on the fourth anniversary of the brutal murder of Fusilier Lee Rigby in Woolwich, south London. Rigby was killed by Michael Adebolajo and Michael Adebowale in the middle of the afternoon on a street outside a military barracks. That attack was in keeping with a pattern we have become increasingly accustomed to in Europe: an unsophisticated plot that employs ordinary, everyday items – a car, say, or a knife.

The consequences of such attacks have been seen across Europe, most notably in Nice on 14 July 2016, when 86 people were killed during Bastille Day celebrations after a jihadist drove a truck into crowds on the promenade. Similar attacks followed in Berlin, Westminster and Stockholm.

The security services find that these murderous attacks are extremely hard to disrupt because they typically involve lone actors who can mobilise quickly and with discretion. The Manchester attack was different. Explosives were used, which means the plot was inherently more sophisticated, requiring careful planning and preparation.

We know that two of the 7/7 bombers had previously trained in Pakistan’s lawless tribal regions, where they honed their skills. In other plots, such as the connected attacks in London and Glasgow Airport of 2007, the explosive devices failed mainly because the bomb-makers had found it difficult to travel abroad and develop their skills in safe environments. Whatever Abedi’s connections, the long war in Syria and Iraq has once again created a permissive environment for terrorist training and attack planning.

The devastating impact of this has already been felt across Europe. Since the Syrian uprising began in 2011, more than 800 Britons are believed to have travelled there to fight. From Europe as a whole, the figure is over 5,000, of which a significant number are believed to have joined IS. Of the British contingent, the security services estimate that about half have returned or become disengaged from the conflict. Of those who remained, a hundred are believed to be active, the rest having been killed.

It is improbable that Abedi acted alone in Manchester or that this plot had no international component. Indeed, he was already known to the authorities (and had returned recently from Libya). As pressure on IS intensifies across Syria and Iraq, the threat to Britain will only become more acute as the group’s sympathisers prepare for what they consider to be a fightback.

This speaks to the scale of the threat facing Britain, and Europe more generally. Our police and security services have been stretched and continuously tested in recent years. Just recently, in March, the Metropolitan Police assistant commissioner Mark Rowley told Radio 4’s Today programme that 13 plots had been thwarted since Lee Rigby’s murder in 2013. Put another way, the police have disrupted terrorist plots every four months for the past four years.

Naturally, Islamic State is not the only threat. On 13 May, one of Osama Bin Laden’s sons, Hamza, released a video, titled “Advice for martyrdom-seekers in the West”, on behalf of al-Qaeda. Hamza, 27, who was his father’s favoured successor to lead the group, called on its supporters to concentrate on attacks in the West rather than migrating to conflict zones in the Middle East and beyond. Scenes of previous ­terrorist attacks in Britain played throughout the video.

The central leadership of al-Qaeda is increasingly looking for opportunities to reassert itself after being eclipsed by Islamic State and losing control of its affiliates in Syria. It needs attacks and a cause in the West with which to revive itself. Hamza therefore cited the January 2015 Charlie Hebdo attack in Paris as a critical example, calling for the assassination of anyone deemed to have “insulted” Islam.

The Charlie Hebdo attack was especially important for al-Qaeda because it enabled the group to transcend the fratricidal conflicts that frequently define relations between the various jihadist groups. In Syria, for instance, al-Qaeda’s affiliates (when it had better control over them) and Islamic State have been in open war with each other.

Yet, the Charlie Hebdo attack brought warm praise from the group’s Islamist rivals because none of them wanted to appear ­unsupportive of an atrocity that had, as the terrorists proclaimed, “avenged” the Prophet Muhammad’s honour.

The British man from High Wycombe who joined IS told me the group had welcomed the attack for precisely those reasons. It was something that, in his view, had confirmed the “nobility” of the attackers, even if they had not been members of IS.

Is it too late for the West to save itself, I asked him. What if the West simply accepted all of Islamic State’s demands: would that provide respite?

The answer was as emphatic as it was stark: “We primarily fight wars due to ppl [sic] being disbelievers. Their drones against us are a secondary issue.”

He went on: “Their kufr [disbelief] against Allah is sufficient of a reason for us to invade and kill them. Only if they stop their kufr will they no longer be a target.”

In other words, we are all guilty, and we are all legitimate targets.
