Babylonia vs. Greece

Saturday, March 21, 2009

The elite attack on ancient Greek achievement is made manifest in London, Paris, and Berlin.

The August heat made Berlin feel like Baghdad. Inside the Pergamon Museum, and constructed specially for the travelling Babylon show, were narrow winding ways impenetrable to air conditioning. In packed discomfort hundreds of us were slowly inching past glass cases of cuneiform tablets—little panels of baked brick that seem to have been Mesopotamia’s main industrial product. One of them told of Babylon’s creation epic. Another contained a magical spell. The biggest invariably declaimed the power of kings. Craning our heads we tried hard to read the labels and tried just as hard to be impressed.

Being impressed by Mesopotamia was the point. For too long had Hellenism been uncritically exalted in the West. Now it was time for the glory that was Greece and the grandeur that was Rome to stand aside so that we could gaze upon the je ne sais quoi that was Mesopotamia. But what exactly was Babylon? Imperial majesty? Architectural folly? A voluptuary paradise? Oriental despotism incarnate? To try to answer these questions the combined museological might of the British Museum, the Musée du Louvre, and the Staatliche Museen zu Berlin had assembled a display of things Babylonian under the title Babylon: Myth and Reality. Early in 2008, the exhibition had begun its travels in Paris; it was in Berlin at the time of my visit; and it was in London until last Sunday.

But if the existing Ishtar Gate made the choice of the Pergamon Museum inevitable, it was also a risky and perhaps even self-defeating decision. For as its name suggests, the main display at this establishment on Berlin’s “Museum Island” is one of Hellenism’s most astonishing artefacts, the Pergamon Altar, with over 100 yards of sculptured friezes as eye-catching as anything from the Parthenon. This is a decidedly hard act to follow: once seen never forgotten. And the altar and its frieze is the first thing visitors did see. Only after this marvel did they move along to find what Mesopotamia had to offer.

Is it conceivable that whole decades of research reveal no Persian literary endeavors to compare with the achievements of the Greeks?

Of course there were other items of interest from Babylon besides the gate. There were rigid busts thought to show this king or that. The seven-foot-high black basalt stone on which Hammurabi’s Code was written around 1750 BC is a useful reminder of the historic place of law in civilized society. A third stone, about 24 inches by 20 inches dating from Nebuchadnezzar’s reign (605562 BC) and containing four columns of early cuneiform script, is described in the catalogue as “a masterpiece of archaizing Babylonian epigraphy”—and no doubt it is.

But what is inscribed? What royal ruminations are here set down that might claim our attention, diverting it from things Greek? We were told it "memorializes Nebuchadnezzar’s building operations in stone. After quoting his royal titles and describing his personal piety, it describes the decorating of the chapels of Marduk, Zarpanitu, and Nabu, the reconstruction of the processional boat of Marduk, the rebuilding of the Akitu house, the restoration of the Babylon temples," and so on. Peggy Lee’s disenchanted question has no doubt been overworked, yet it was difficult to emerge from those claustrophobic museum corridors without gasping “Is that all there is?” What literary evidence is there from antiquity of a polity and a culture meriting as much attention as ancient Greece?

One wonders about the motives behind the exhibition itself. Topically, they plainly had to do with current events in Iraq and at the Baghdad Museum—a concluding chapter in the British Museum’s English-language catalogue says as much. But they also go deeper than that. For much of the past 30 years admirers of classical Greece have been on the defensive, while easternizing admirers of Mesopotamia—which includes the Assyrians, the 6th century BC Babylon of Nebuchadnezzar, and the Persians who took over under Cyrus in 539 BC—have been on the attack. Darius and Co. have been talked up; Pericles and Herodotus and Co. have been talked down.

That distinguished and venerable classicist Peter Green apologised for having been too keen for freedom in his 1970 book Xerxes at Salamis. Revising it in 1996 under the new title The Greco-Persian Wars, he regretted embracing so enthusiastically “the fundamental Herodotean concept of freedom-under-law (eleutheria, isonomia) making its great and impassioned stand against Oriental Despotism.” What he called “the insistent lessons of multiculturalism” had forced all classical scholars “to take a long hard look at Greek ‘anti-barbarian’ propaganda, beginning with Aeschylus’s Persians and the whole thrust of Herodotus’s Histories.”

The Oxford University Press author of the 2003 The Greek Wars, George Cawkwell, told us in a short preface that he was proud to be part of a scholarly movement that aims “to rid ourselves of a Hellenocentric view of the Persian world.” Much of the first three pages of his introduction then proceeded to ridicule and discredit Herodotus, who showed “an astounding misapprehension” concerning the Persians, whose stories were sometimes delightful but were certainly absurd, and who, he wrote, “had no real understanding of the Persian Empire.”

But if Herodotus didn’t get it right, who exactly did? Obviously, some nameless Persian equivalent to Herodotus might have had “a real understanding of the Persian Empire,” but who was he and where is his narrative? What book by which contemporary Persian historian provides an alternative account of Achaemenid manners and customs, institutions and political thought, imperial policy and administration and ideals?

For much of the past 30 years admirers of classical Greece have been on the defensive, while easternizing admirers of Mesopotamia have been on the attack.

The courts of Cyrus the Great, Darius the Great, not to mention Xerxes, King of Kings, employed armies of chroniclers recording royal achievements and military victories. Is it conceivable that whole decades of the recent research invoked by Peter Green and Tom Holland (author of the 2005 book Persian Fire) reveal no Persian literary endeavors to compare with the achievements of the Greeks?

Alas, that seems to be the case. Even the Oxford don so jeeringly hostile to Herodotus admits that though the evidence of past Persian glories “is ample and various, one thing is lacking. Apart from the Behistun Inscription which gives an account of the opening of the reign of Darius I, there are no literary accounts of Achaemenid history other than those written by Greeks.” Moreover, he admits, such literacy as existed in the Persian Empire was largely Greek; and such writing as took place was mainly done by Greeks.

Escaping out through the monumental Ishtar Gate into the rest of the Pergamon Museum, one was glad to be again surrounded by Hellenistic sculptures. It was like taking off from a barren desert airstrip and landing in Paris. Human faces. Faces of human scale alive with familiar emotions. In the remarkable Telephos Frieze there were youthful and elegant figures clothed in drapery, arranged with all the delicacy of civilized feeling and all the art that gifted sculptors can bestow. Gods like men and men like gods. Exploring in the nearby Graeco-Roman collection one found, instead of the heartless faces of despots, the marble statue of a young girl playing knucklebones.

Ten principles for a Black Swan-proof world

1. What is fragile should break early while it is still small. Nothing should ever become too big to fail. Evolution in economic life helps those with the maximum amount of hidden risks – and hence the most fragile – become the biggest.

2. No socialisation of losses and privatisation of gains. Whatever may need to be bailed out should be nationalised; whatever does not need a bail-out should be free, small and risk-bearing. We have managed to combine the worst of capitalism and socialism. In France in the 1980s, the socialists took over the banks. In the US in the 2000s, the banks took over the government. This is surreal.

3. People who were driving a school bus blindfolded (and crashed it) should never be given a new bus. The economics establishment (universities, regulators, central bankers, government officials, various organisations staffed with economists) lost its legitimacy with the failure of the system. It is irresponsible and foolish to put our trust in the ability of such experts to get us out of this mess. Instead, find the smart people whose hands are clean.

4. Do not let someone making an "incentive" bonus manage a nuclear plant – or your financial risks. Odds are he would cut every corner on safety to show "profits" while claiming to be "conservative". Bonuses do not accommodate the hidden risks of blow-ups. It is the asymmetry of the bonus system that got us here. No incentives without disincentives: capitalism is about rewards and punishments, not just rewards.

5. Counter-balance complexity with simplicity. Complexity from globalisation and highly networked economic life needs to be countered by simplicity in financial products. The complex economy is already a form of leverage: the leverage of efficiency. Such systems survive thanks to slack and redundancy; adding debt produces wild and dangerous gyrations and leaves no room for error. Capitalism cannot avoid fads and bubbles: equity bubbles (as in 2000) have proved to be mild; debt bubbles are vicious.

6. Do not give children sticks of dynamite, even if they come with a warning . Complex derivatives need to be banned because nobody understands them and few are rational enough to know it. Citizens must be protected from themselves, from bankers selling them "hedging" products, and from gullible regulators who listen to economic theorists.

7. Only Ponzi schemes should depend on confidence. Governments should never need to "restore confidence". Cascading rumours are a product of complex systems. Governments cannot stop the rumours. Simply, we need to be in a position to shrug off rumours, be robust in the face of them.

8. Do not give an addict more drugs if he has withdrawal pains. Using leverage to cure the problems of too much leverage is not homeopathy, it is denial. The debt crisis is not a temporary problem, it is a structural one. We need rehab.

9. Citizens should not depend on financial assets or fallible "expert" advice for their retirement. Economic life should be definancialised. We should learn not to use markets as storehouses of value: they do not harbour the certainties that normal citizens require. Citizens should experience anxiety about their own businesses (which they control), not their investments (which they do not control).

10. Make an omelette with the broken eggs. Finally, this crisis cannot be fixed with makeshift repairs, no more than a boat with a rotten hull can be fixed with ad-hoc patches. We need to rebuild the hull with new (stronger) materials; we will have to remake the system before it does so itself. Let us move voluntarily into Capitalism 2.0 by helping what needs to be broken break on its own, converting debt into equity, marginalising the economics and business school establishments, shutting down the "Nobel" in economics, banning leveraged buyouts, putting bankers where they belong, clawing back the bonuses of those who got us here, and teaching people to navigate a world with fewer certainties.

Then we will see an economic life closer to our biological environment: smaller companies, richer ecology, no leverage. A world in which entrepreneurs, not bankers, take the risks and companies are born and die every day without making the news.

In other words, a place more resistant to black swans.

Hubris paved way to crisis

By DANIEL CLOUD


PRINCETON, New Jersey — To understand how we got ourselves into our current economic mess, complicated explanations about derivatives, regulatory failure, and so on are beside the point. The best answer is both ancient and simple: hubris.


In modern mathematical economics, many people in the rich world decided that we had finally devised a set of scientific tools that could really predict human behavior. These tools were supposed to be as reliable as those used in engineering. Having ushered scientific socialism into its grave at the Cold War's end, we quickly found ourselves embracing another science of man.

Our new beliefs did not stem from some new experiment or unexpected observation, the way a real scientific paradigm shift does. Economists do not typically conduct experiments with real money. When they do, as when the Nobel laureate Myron Scholes ran the hedge fund Long Term Capital Management (LTCM), the dangers often outweigh the benefits (a lesson we still don't seem to have learned.) And, since almost every observation that economists make turns out in a way that wasn't predicted, no unexpected observation could ever actually change an economic paradigm.

What really produced the change in economics that led to disaster was the simple fact that you could now get away with saying certain kinds of things in public. Some of us honestly thought that history was over. And after all, you can't have a final, utopian society without having a final, scientific theory of human behavior, together with some mad scientists or philosophes to preside over the whole thing.


The problem is that, no matter how "scientifically" these new beliefs were formulated, they are still false. Capitalism is, among other things, a struggle between individual people over the control of scarce resources. Like boxing and poker, it is a soft, restrained, private form of warfare.

Military strategists have known for centuries that there is, and can be, no final science of war. In a real struggle over things that actually matter, we must assume that we are up against thinking opponents, who may understand some things about us that we don't know about ourselves. For example, if profit can be made by understanding the model behind a policy, as is surely the case with the models used by the U.S. Federal Reserve, sooner or later so much capital will seek that profit that the tail will begin to wag the dog, as has been happening lately.

The truth is that such models are most useful when they are little known or not universally believed. They progressively lose their predictive value as we all accept and begin to bet on them. But there can be no real predictive science for a system that may change its behavior if we publish a model of it.

Markets might once have been fairly efficient, before we had the theory of efficient markets. If investing is simply a matter of allocating money to an index, however, liquidity becomes the sole determinant of prices, and valuations go haywire. When a substantial fraction of market participants are simply buying the index, the market's role in ensuring good corporate governance also disappears.

The formation of large bubbles in recent decades was partly a consequence of the commonness and incorrigibility of the belief that no such thing could ever happen. Our collective belief that markets are efficient helped make them wildly inefficient.

Despite this, over the course of the last 20 years, economists began to act as if we thought we could genuinely predict the economic future. If the universe didn't oblige, it wasn't because our models were wrong; "market failure" was to blame. It is not clear how we could know that markets were failing whenever they fell significantly, but believed that we had no business second-guessing them when they climbed. Nor is it clear how we all knew that LTCM's failure or the post-Sept. 11 malaise posed grave risks to the system, but could seriously doubt that the dot-com craze was a bubble.

We repeatedly rescued bubbles, and never deliberately burst them. As a result, our financial markets became a pyramid scheme. Moral hazard, we thought, could safely be ignored, because it is "moral," which, as every true scientist knows, just means "imaginary."

But a market is not a rocket, economists are not rocket scientists, and moral hazard is, in human affairs, the risk that matters most. The false belief that we can collectively see the future using science has led us all to make various binding promises about things in that future that no human being can possibly guarantee. A promise of something that we should know cannot be guaranteed is also known as a lie. That vast tissue of lies is now tearing itself apart.

Governments think we can stop this process by throwing money at it, but there are many reasons to believe that this won't work. The banking system is probably already past saving — many institutions simply aren't banks anymore, but vast experiments that didn't work out as predicted.

We could easily be "stimulating" and "rescuing" the economy for a rather long time, in ways that only delay the needed adjustment, before we are finally forced to allow the required creative destruction to occur. But that is not the real problem. The real problem is the pseudoscientific ideology behind today's crisis. A final science of man has no room for the unplanned and unpredictable recovery that is the only kind a capitalist economy can have after a crisis of this size.

If we cleave to the false security of a supposed science that isn't working, and forget about the philosophy behind it, ideas like personal responsibility and the right to fail, our leaders will very scientifically give us no recovery at all.
