The Evolution of Everything: How Small Changes Transform Our World. Matt Ridley
was acutely aware of this parallel with language, which is why he insisted on appending his short essay on the origin of language to his Theory of Moral Sentiments in its second and later editions. In the essay, Smith makes the point that the laws of language are an invention, rather than a discovery – unlike, say, the laws of physics. But they are still laws: children are corrected by their parents and their peers if they say ‘bringed’ instead of ‘brought’. So language is an ordered system, albeit arrived at spontaneously through some kind of trial and error among people trying to make ‘their mutual wants intelligible to each other’. Nobody is in charge, but the system is orderly. What a peculiar and novel idea. What a subversive thought. If God is not needed for morality, and if language is a spontaneous system, then perhaps the king, the pope and the official are not quite as vital to the functioning of an orderly society as they pretend?
As the American political scientist Larry Arnhart puts it, Smith is a founder of a key tenet of liberalism, because he rejects the Western tradition that morality must conform to a transcendental cosmic order, whether in the form of a cosmic God, a cosmic Reason, or a cosmic Nature. ‘Instead of this transcendental moral cosmology, liberal morality is founded on an empirical moral anthropology, in which moral order arises from within human experience.’
Above all, Smith allows morality and language to change, to evolve. As Otteson puts it, for Smith, moral judgements are generalisations arrived at inductively on the basis of past experience. We log our own approvals and disapprovals of our own and others’ conduct, and observe others doing the same. ‘Frequently repeated patterns of judgement can come to have the appearance of moral duties or even commandments from on high, while patterns that recur with less frequency will enjoy commensurately less confidence.’ It is in the messy empirical world of human experience that we find morality. Moral philosophers observe what we do; they do not invent it.
Better angels
Good grief. Here is an eighteenth-century, middle-class Scottish professor saying that morality is an accidental by-product of the way human beings adjust their behaviour towards each other as they grow up; saying that morality is an emergent phenomenon that arises spontaneously among human beings in a relatively peaceful society; saying that goodness does not need to be taught, let alone associated with the superstitious belief that it would not exist but for the divine origin of an ancient Palestinian carpenter. Smith sounds remarkably like Lucretius (whom he certainly read) in parts of his Moral Sentiments book, but he also sounds remarkably like Steven Pinker of Harvard University today discussing the evolution of society towards tolerance and away from violence.
As I will explore, there is in fact a fascinating convergence here. Pinker’s account of morality growing strongly over time is, at bottom, very like Smith’s. To put it at its baldest, a Smithian child, developing his sense of morality in a violent medieval society in Prussia (say) by trial and error, would end up with a moral code quite different from such a child growing up in a peaceful German (say) suburb today. The medieval person would be judged moral if he killed people in defence of his honour or his city; whereas today he would be thought moral if he refused meat and gave copiously to charity, and thought shockingly immoral if he killed somebody for any reason at all, and especially for honour. In Smith’s evolutionary view of morality, it is easy to see how morality is relative and will evolve to a different end point in different societies, which is exactly what Pinker documents.
Pinker’s book The Better Angels of Our Nature chronicles the astonishing and continuing decline in violence of recent centuries. We have just lived through the decade with the lowest global death rate in warfare on record; we have seen homicide rates fall by 99 per cent in most Western countries since medieval times; we have seen racial, sexual, domestic, corporal, capital and other forms of violence in headlong retreat; we have seen discrimination and prejudice go from normal to disgraceful; we have come to disapprove of all sorts of violence as entertainment, even against animals. This is not to say there is no violence left, but the declines that Pinker documents are quite remarkable, and our horror at the violence that still remains implies that the decline will continue. Our grandchildren will stand amazed at some of the things we still find quite normal.
To explain these trends, Pinker turns to a theory first elaborated by Norbert Elias, who had the misfortune to publish it as a Jewish refugee from Germany in Britain in 1939, shortly before he was interned by the British on the grounds that he was German. Not a good position from which to suggest that violence and coercion were diminishing. It was not until it was translated into English three decades later in 1969, in a happier time, that his theory was widely appreciated. Elias argued that a ‘civilising process’ had sharply altered the habits of Europeans since the Middle Ages, that as people became more urban, crowded, capitalist and secular, they became nicer too. He hit upon this paradoxical realisation – for which there is now, but was not then, strong statistical evidence – by combing the literature of medieval Europe and documenting the casual, frequent and routine violence that was then normal. Feuds flared into murders all the time; mutilation and death were common punishments; religion enforced its rules with torture and sadism; entertainments were often violent. Barbara Tuchman in her book A Distant Mirror gives an example of a popular game in medieval France: people with their hands tied behind their backs competed to kill a cat nailed to a post by battering it with their heads, risking the loss of an eye from the scratching of the desperate cat in the process. Ha ha.
Elias argued that moral standards evolved; to illustrate the point he documented the etiquette guides published by Erasmus and other philosophers. These guides are full of suggestions about table manners, toilet manners and bedside manners that seem unnecessary to state, but are therefore revealing: ‘Don’t greet someone while they are urinating or defecating … don’t blow your nose on to the table-cloth or into your fingers, sleeve or hat … turn away when spitting lest your saliva fall on someone … don’t pick your nose while eating.’ In short, the very fact that these injunctions needed mentioning implies that medieval European life was pretty disgusting by modern standards. Pinker comments: ‘These are the kind of directives you’d expect a parent to give to a three-year-old, not a great philosopher to a literate readership.’ Elias argued that the habits of refinement, self-control and consideration that are second nature to us today had to be acquired. As time went by, people ‘increasingly inhibited their impulses, anticipated the long-term consequences of their actions, and took other people’s thoughts and feelings into consideration’. In other words, not blowing your nose on the tablecloth was all one with not stabbing your neighbour. It’s a bit like a historical version of the broken-window theory: intolerance of small crimes leads to intolerance of big ones.
Doux commerce
But how were these gentler habits acquired? Elias realised that we have internalised the punishment for breaking these rules (and the ones against more serious violence) in the form of a sense of shame. That is to say, just as Adam Smith argued, we rely on an impartial spectator, and we learned earlier and earlier in life to see his point of view as he became ever more censorious. But why? Elias and Pinker give two chief reasons: government and commerce. With an increasingly centralised government focused on the king and his court, rather than local warlords, people had to behave more like courtiers and less like warriors. That meant not only less violent, but also more refined. Leviathan enforced the peace, if only to have more productive peasants to tax. Revenge for murder was nationalised as a crime to be punished, rather than privatised as a wrong to be righted. At the same time, commerce led people to value the opportunity to be trusted by a stranger in a transaction. With increasingly money-based interactions among strangers, people increasingly began to think of neighbours as potential trading partners rather than potential prey. Killing the shopkeeper makes no sense. So empathy, self-control and morality became second nature, though morality was always a double-edged sword, as likely to cause violence as to prevent it through most of history.
Lao Tzu saw this twenty-six centuries ago: ‘The more prohibitions you have, the less virtuous people will be.’ Montesquieu’s phrase for the calming effect of trade on human violence, intolerance and enmity was ‘doux commerce’ – sweet commerce. And he has been amply vindicated in the centuries since. The richer
