More importantly, the analogy between history and biology that underpins the ‘clash of civilisations’ thesis is false. Human groups – all the way from small tribes to huge civilisations – are fundamentally different from animal species, and historical conflicts greatly differ from natural selection processes. Animal species have objective identities that endure for thousands upon thousands of generations. Whether you are a chimpanzee or a gorilla depends on your genes rather than your beliefs, and different genes dictate distinct social behaviours. Chimpanzees live in mixed groups of males and females. They compete for power by building coalitions of supporters from among both sexes. Amid gorillas, in contrast, a single dominant male establishes a harem of females, and usually expels any adult male that might challenge his position. Chimpanzees cannot adopt gorilla-like social arrangements; gorillas cannot start organising themselves like chimpanzees; and as far as we know exactly the same social systems have characterised chimpanzees and gorillas not only in recent decades, but for hundreds of thousands of years.

  You find nothing like that among humans. Yes, human groups may have distinct social systems, but these are not genetically determined, and they seldom endure for more than a few centuries. Think of twentieth-century Germans, for example. In less than a hundred years the Germans organised themselves into six very different systems: the Hohenzollern Empire, the Weimar Republic, the Third Reich, the German Democratic Republic (aka communist East Germany), the Federal Republic of Germany (aka West Germany), and finally democratic reunited Germany. Of course the Germans kept their language and their love of beer and bratwurst. But is there some unique German essence that distinguishes them from all other nations, and that has remained unchanged from Wilhelm II to Angela Merkel? And if you do come up with something, was it also there 1,000 years ago, or 5,000 years ago?

  The (unratified) Preamble of the European Constitution begins by stating that it draws inspiration ‘from the cultural, religious and humanist inheritance of Europe, from which have developed the universal values of the inviolable and inalienable rights of the human person, democracy, equality, freedom and the rule of law’.3 This may easily give one the impression that European civilisation is defined by the values of human rights, democracy, equality and freedom. Countless speeches and documents draw a direct line from ancient Athenian democracy to the present-day EU, celebrating 2,500 years of European freedom and democracy. This is reminiscent of the proverbial blind man who takes hold of an elephant’s tail and concludes that an elephant is a kind of brush. Yes, democratic ideas have been part of European culture for centuries, but they were never the whole. For all its glory and impact, Athenian democracy was a half-hearted experiment that survived for barely 200 years in a small corner of the Balkans. If European civilisation for the past twenty-five centuries has been defined by democracy and human rights, what are we to make of Sparta and Julius Caesar, of the Crusaders and the conquistadores, of the Inquisition and the slave trade, of Louis XIV and Napoleon, of Hitler and Stalin? Were they all intruders from some foreign civilisation?

  In truth, European civilisation is anything Europeans make of it, just as Christianity is anything Christians make of it, Islam is anything Muslims make of it, and Judaism is anything Jews make of it. And they have made of it remarkably different things over the centuries. Human groups are defined more by the changes they undergo than by any continuity, but they nevertheless manage to create for themselves ancient identities thanks to their storytelling skills. No matter what revolutions they experience, they can usually weave old and new into a single yarn.

  Even an individual may knit revolutionary personal changes into a coherent and powerful life story: ‘I am that person who was once a socialist, but then became a capitalist; I was born in France, and now live in the USA; I was married, and then got divorced; I had cancer, and then got well again.’ Similarly a human group such as the Germans may come to define itself by the very changes it underwent: ‘Once we were Nazis, but we have learnt our lesson, and now we are peaceful democrats.’ You don’t need to look for some unique German essence that manifested itself first in Wilhelm II, then in Hitler, and finally in Merkel. These radical transformations are precisely what define German identity. To be German in 2018 means to grapple with the difficult legacy of Nazism while upholding liberal and democratic values. Who knows what it will mean in 2050.

  People often refuse to see these changes, especially when it comes to core political and religious values. We insist that our values are a precious legacy from ancient ancestors. Yet the only thing that allows us to say this, is that our ancestors are long dead, and cannot speak for themselves. Consider, for example, Jewish attitudes towards women. Nowadays ultra-Orthodox Jews ban images of women from the public sphere. Billboards and advertisements aimed at ultra-Orthodox Jews usually depict only men and boys – never women and girls.4

  In 2011, a scandal erupted when the ultra-Orthodox Brooklyn paper Di Tzeitung published a photo of American officials watching the raid on Osama bin-Laden’s compound but digitally erased all women from the photo, including Secretary of State Hillary Clinton. The paper explained it was forced to do so by Jewish ‘laws of modesty’. A similar scandal erupted when HaMevaser paper expunged Angela Merkel from a photo of a demonstration against the Charlie Hebdo massacre, lest her image arouse any lustful thoughts in the minds of devout readers. The publisher of a third ultra-Orthodox newspaper, Hamodia, defended this policy by explaining that ‘We are backed by thousands of years of Jewish tradition.’5

  Nowhere is the ban on seeing women stricter than in the synagogue. In Orthodox synagogues women are carefully segregated from the men, and must confine themselves to a restricted zone where they are hidden behind a curtain, so that no men will accidentally see the shape of a woman as he says his prayers or reads scriptures. Yet if all this is backed by thousands of years of Jewish tradition and immutable divine laws, how to explain the fact that when archaeologists excavated ancient synagogues in Israel from the time of the Mishnah and Talmud, they found no sign of gender segregation, and instead uncovered beautiful floor mosaics and wall paintings depicting women, some of them rather scantily dressed? The rabbis who wrote the Mishnah and Talmud regularly prayed and studied in these synagogues, but present-day Orthodox Jews would consider them blasphemous desecrations of ancient traditions.6

  Similar distortions of ancient traditions characterise all religions. The Islamic State has boasted that it has reverted to the pure and original version of Islam, but in truth, their take on Islam is brand new. Yes, they quote many venerable texts, but they exercise a lot of discretion in choosing which texts to quote and which to ignore, and in how to interpret them. Indeed, their do-it-yourself attitude to interpreting the holy texts is itself very modern. Traditionally, interpretation was the monopoly of the learned ulama – scholars who studied Muslim law and theology in reputable institutions such as Cairo’s Al-Azhar. Few of the Islamic State’s leaders have had such credentials, and most respected ulama have dismissed Abu Bakr al-Baghdadi and his ilk as ignorant criminals.7

  That does not mean that the Islamic State has been ‘un-Islamic’ or ‘anti-Islamic’, as some people argue. It is particularly ironic when Christian leaders such as Barack Obama have the temerity to tell self-professing Muslims such as Abu Bakr al-Baghdadi what it means to be Muslim.8 The heated argument about the true essence of Islam is simply pointless. Islam has no fixed DNA. Islam is whatever Muslims make of it.9

  Germans and gorillas

  There is an even deeper difference distinguishing human groups from animal species. Species often split, but they never merge. About 7 million years ago chimpanzees and gorillas had common ancestors. This single ancestral species split into two populations that eventually went their separate evolutionary ways. Once this happened, there was no going back. Since individuals belonging to different species cannot produce fertile offspring together, species can never merge. Gorillas cannot merge with chimpanzees, giraffes cannot merge with el
ephants, and dogs cannot merge with cats.

  Human tribes, in contrast, tend to coalesce over time into larger and larger groups. Modern Germans were created from the merger of Saxons, Prussians, Swabians and Bavarians, who not so long ago wasted little love on one another. Otto von Bismarck allegedly remarked (having read Darwin’s On the Origin of Species) that the Bavarian is the missing link between the Austrian and the human.10 The French were created from the merger of Franks, Normans, Bretons, Gascons and Provençals. Meanwhile across the Channel, English, Scots, Welsh and Irish were gradually welded together (willingly or not) to form Britons. In the not too distant future, Germans, French and Britons might yet merge into Europeans.

  Mergers don’t always last, as people in London, Edinburgh and Brussels are keenly aware these days. Brexit may well initiate the simultaneous unravelling of both the UK and the EU. But in the long run, history’s direction is clear-cut. Ten thousand years ago humankind was divided into countless isolated tribes. With each passing millennium, these fused into larger and larger groups, creating fewer and fewer distinct civilisations. In recent generations the few remaining civilisations have been blending into a single global civilisation. Political, ethnic, cultural and economic divisions endure, but they do not undermine the fundamental unity. Indeed, some divisions are made possible only by an overarching common structure. In the economy, for example, division of labour cannot succeed unless everyone shares a single market. One country cannot specialise in producing cars or oil unless it can buy food from other countries that grow wheat and rice.

  The process of human unification has taken two distinct forms: establishing links between distinct groups, and homogenising practices across groups. Links may be formed even between groups that continue to behave very differently. Indeed, links may form even between sworn enemies. War itself can generate some of the strongest of all human bonds. Historians often argue that globalisation reached a first peak in 1913, then went into a long decline during the era of the world wars and the Cold War, and recuperated only after 1989.11 This may be true of economic globalisation, but it ignores the different but equally important dynamic of military globalisation. War spreads ideas, technologies and people far more quickly than commerce. In 1918 the United States was more closely linked to Europe than in 1913, the two then drifted apart in the interwar years, only to have their fates meshed together inextricably by the Second World War and the Cold War.

  War also makes people far more interested in one another. Never had the US been more closely in touch with Russia than during the Cold War, when every cough in a Moscow corridor sent people scrambling up and down Washington staircases. People care far more about their enemies than about their trade partners. For every American film about Taiwan, there are probably fifty about Vietnam.

  The Medieval Olympics

  The world of the early twenty-first century has gone way beyond forming links between different groups. People across the globe are not only in touch with one another, they increasingly share identical beliefs and practices. A thousand years ago, planet Earth provided fertile ground to dozens of different political models. In Europe you could find feudal principalities vying with independent city states and minuscule theocracies. The Muslim world had its caliphate, claiming universal sovereignty, but also experimented with kingdoms, sultanates and emirates. The Chinese empires believed themselves to be the sole legitimate political entity, while to the north and west tribal confederacies fought each other with glee. India and South East Asia contained a kaleidoscope of regimes, whereas polities in America, Africa and Australasia ranged from tiny hunter-gatherer bands to sprawling empires. No wonder that even neighbouring human groups had trouble agreeing on common diplomatic procedures, not to mention international laws. Each society had its own political paradigm, and found it difficult to understand and respect alien political concepts.

  Today, in contrast, a single political paradigm is accepted everywhere. The planet is divided between about 200 sovereign states, which generally agree on the same diplomatic protocols and on common international laws. Sweden, Nigeria, Thailand and Brazil are all marked on our atlases as the same kind of colourful shapes; they are all members of the UN; and despite myriad differences they are all recognised as sovereign states enjoying similar rights and privileges. Indeed, they share many more political ideas and practices, including at least a token belief in representative bodies, political parties, universal suffrage and human rights. There are parliaments in Tehran, Moscow, Cape Town and New Delhi as well as in London and Paris. When Israelis and Palestinians, Russians and Ukrainians, Kurds and Turks compete for the favours of global public opinion, they all use the same discourse of human rights, state sovereignty and international law.

  The world may be peppered with various types of ‘failed states’, but it knows only one paradigm for a successful state. Global politics thus follows the Anna Karenina principle: successful states are all alike, but every failed state fails in its own way, by missing this or that ingredient of the dominant political package. The Islamic State has recently stood out in its complete rejection of this package, and in its attempt to establish an entirely different kind of political entity – a universal caliphate. But precisely for this reason it has failed. Numerous guerrilla forces and terror organisations have managed to establish new countries or to conquer existing ones. But they have always done so by accepting the fundamental principles of the global political order. Even the Taliban sought international recognition as the legitimate government of the sovereign country of Afghanistan. No group rejecting the principles of global politics has so far gained any lasting control of any significant territory.

  The strength of the global political paradigm can perhaps best be appreciated by considering not hardcore political questions of war and diplomacy, but rather something like the 2016 Rio Olympics. Take a moment to reflect on the way the Games were organised. The 11,000 athletes were grouped into delegations by nationality rather than by religion, class or language. There was no Buddhist delegation, proletarian delegation, or English-speaking delegation. Except in a handful of cases – most notably Taiwan and Palestine – determining the athletes’ nationality was a straightforward affair.

  At the opening ceremony on 5 August 2016 the athletes marched in groups, each group waving its national flag. Whenever Michael Phelps won another gold medal, the Stars and Stripes was raised to the sound of the ‘Star-Spangled Banner’. When Emilie Andéol won the gold medal in judo, the French tricolour was hoisted and the ‘Marseillaise’ was played.

  Conveniently enough, each country in the world has an anthem that conforms to the same universal model. Almost all anthems are orchestral pieces of a few minutes in length, rather than a twenty-minute chant that may only be performed by a special caste of hereditary priests. Even countries such as Saudi Arabia, Pakistan and Congo have adopted Western musical conventions for their anthems. Most of them sound like something composed by Beethoven on a rather mediocre day. (You can spend an evening with friends playing the various anthems on YouTube and trying to guess which is which.) Even the lyrics are almost the same throughout the world, indicating common conceptions of politics and group loyalty. For example, to which nation do you think the following anthem belongs? (I changed only the country’s name into the generic ‘My country’):

  My country, my homeland,

  The land where I have shed my blood,

  It is there I stand,

  To be my motherland’s guard.

  My country, my nation,

  My people and my homeland,

  Let us proclaim

  ‘My country unite!’

  Long live my land, long live my state,

  My nation, my homeland, in its entirety.

  Build its soul, awaken its body,

  For my great country!

  My great country, independent and free

  My home and my country which I love.

  My great country, independent and free,

&nb
sp; Long live my great country!

  The answer is Indonesia. But would you have been surprised if I told you that the answer was actually Poland, Nigeria or Brazil?

  National flags display the same dreary conformity. With a single exception, all flags are rectangular pieces of cloth marked by an extremely limited repertoire of colours, stripes and geometrical shapes. Nepal is the odd country out, with a flag consisting of two triangles. (But it has never won an Olympic medal.) The Indonesian flag consists of a red stripe above a white stripe. The Polish flag displays a white stripe above a red stripe. The flag of Monaco is identical to that of Indonesia. A colour-blind person could hardly tell the difference between the flags of Belgium, Chad, Ivory Coast, France, Guinea, Ireland, Italy, Mali and Romania – they all have three vertical stripes of various colours.

  Some of these countries have been engaged in bitter war with one another, but during the tumultuous twentieth century only three Games were cancelled due to war (in 1916, 1940 and 1944). In 1980 the USA and some of its allies boycotted the Moscow Olympics, in 1984 the Soviet bloc boycotted the Los Angeles Games, and on several other occasions the Olympics found themselves at the centre of a political storm (most notably in 1936, when Nazi Berlin hosted the Games, and in 1972, when Palestinian terrorists massacred the Israeli delegation to the Munich Olympics). Yet on the whole, political controversies have not derailed the Olympic project.

  Now let’s go back 1,000 years. Suppose you wanted to hold the Medieval Olympic Games in Rio in 1016. Forget for a moment that Rio was then a small village of Tupi Indians,12 and that Asians, Africans and Europeans were not even aware of America’s existence. Forget the logistical problems of bringing all the world’s top athletes to Rio in the absence of airplanes. Forget too that few sports were shared throughout the world, and even if all humans could run, not everybody could agree on the same rules for a running competition. Just ask yourself how to group the competing delegations. Today’s International Olympic Committee spends countless hours discussing the Taiwan question and the Palestine question. Multiply this by 10,000 to estimate the number of hours you would have to spend on the politics of the Medieval Olympics.
