Some years ago Steven Pinker’s book, The Better Angels of Our Nature (Pinker 2012) made a great impression. In this book – using over a thousand pages of text and 100 diagrams – Pinker supported his case that, over the long run, human beings are becoming less violent toward each other. There were exceptions to the decline in violence, but Pinker seemed to make a powerful case for his argument. In addition, he presented a list of factors which, in his view, led to this decline in violence.
Since that time, Pinker’s argument has been verified. Johan Norberg (2016), a Swedish writer and Angus Deaton (2013), a Nobel prize-winner in economics, have come to the same conclusion. The key finding, the long-term decline in interpersonal violence, has to be welcome to everyone. Its sheer magnitude sometimes takes an effort to grasp. For example, an Englishman living in the 1300s was twenty times as likely to die violently as an Englishman in the twentieth century (Pinker 2016:73). Overall, Pinker’s case for the trend away from violence seems to be well supported.
Many wonderful trends
Now Pinker has returned with another book, titled Enlightenment Now (Pinker 2018). It is short compared to the other book – only 550-odd pages and 75 diagrams – but far more ambitious. He documents the evidence that the human condition is improving on more than a dozen important measures. And he has a single underlying theory to explain this.
Rather than list all the trends, I will put them in a separate table, with an example or two for each. Cast your eyes over the table. I suggest looking at the examples for Life, Wealth and Knowledge. Let me stress that in the hundreds of pages and dozens of illustrations which make up Pinker’s book, there are far more trends than I can list here. And all point in the same direction: the human condition worldwide is improving. Usually these improvements took place first in Europe and North America. However, the other parts of the world are improving too, and usually catching up with the leaders.
Table 1. Major trends charted by Pinker, with selected examples
Life. Life expectancy is increasing Around 1780, world life expectancy for humans was about 30 years. Today it is 71.4 years. (Pinker 2018: 53-4 ) Major diseases are in decline, often because of mass vaccination (Pinker 2018: 64).
Sustenance. The food supply per person is increasing and so childhood stunting and famine deaths are in decline (Pinker 2018: 70-71). The size of families is decreasing, too: apparently once parents are reasonably sure that their children will survive, they stop having large families (Pinker 2018: 125).
Wealth. GDP per capita is increasing worldwide and as a result extreme poverty is falling. In 1820, nearly 90% of the world’s population lived on US$1.90 (2011 dollars) or less. Today only about 10% live on so little (Pinker 2018: 87).
Inequality. Inequality may be increasing, but the general trend is for everyone to become richer (Pinker 2018: 120)
The Environment. Because of advancing technology, the risk of environmental catastrophe is receding, and most environmental indicators are improving (Pinker 2018:132-3).
Peace. The peaceful trends discerned in Pinker’s earlier book are shown to have continued (Pinker 2018: 157-9).
Safety. Steady reduction in vehicle accident deaths, plane crash deaths and most other forms of accidental death (Pinker 2018: 179-182).
Terrorism. Worldwide, deaths by terrorism are dwarfed by those from war and accidents (Pinker 2018: 192)
Democracy. Despite recent hiccups, Pinker cites the Polity Project as showing a steady advance for democracy in the world (http://www.systemicpeace.org/polity/polity1.htm) (Pinker 2018; 207).
Equal rights. A general rise in liberal values in nearly all areas of the world over the last 50 years (Pinker 2018: 227). A decline in racist, sexist and homophobic jokes on the internet (Pinker 2018: 218).
Knowledge. Great rises in literacy worldwide (Pinker 2018: 238). Back in 1475 20% or less of the people in European nations were literate. Today over 90% are, and the rest of the world is improving too.
Quality of Life. Decline in working hours in Europe and the USA, decline in housework hours, rise in useful household devices. Increase in leisure time (Pinker 2018: 249-256)
Happiness. Reported life satisfaction is correlated with physical wellbeing, and seems to be improving (Pinker 2018: 269-279)
Existential Threats. The worldwide stock of nuclear weapons is diminishing (Pinker 2018: 318), and doom-laden predictions have repeatedly been proved wrong (Pinker 2018: 309)
The Cause of It All
However, Pinker is not simply a Pollyanna, exclaiming at how wonderful everything is. He has a theory as to what underlies all these wonderful trends, and he also thinks that there is a threat to the entire process. As the title of his book suggests, he regards the Enlightenment as being a key cause of all this human improvement.
What do we mean by the Enlightenment? Pinker concedes that, unlike the Olympics, there was no opening and closing ceremony: you can argue about it endlessly (Pinker 2018: 7-8). However, he distinguishes some features of Enlightenment thinking. One theme is the use of reason, which leads to doubt and questioning. Another is the refinement of reason to understand the world. (Personally I regard this as an extension of reason, or using it in a special way.) Part of this understanding involves knowing ourselves, and how our minds and bodies work. A third attribute is humanism, involving a morality which privileges human welfare. Finally there is a belief in progress. Pinker stresses that these basic themes are not absolute: people are not completely reasonable, nor is progress guaranteed.
As he works through all the trends operating in the world today, Pinker tries to link them back to Enlightenment influences. For example, Enlightenment thinking values commerce because it involves free exchange and economic improvement. Although commerce can be tough at times, it creates wealth and is far, far better than war, destruction and murder. Again, Enlightenment thought leads to the questioning of cruel judicial punishments.
In my view, the least convincing of Pinker’s arguments is the one over inequality. His chapter on this is largely a response to the French economist Thomas Piketty (2013). Using massive amounts of evidence, Piketty argued that western nations are becoming less equal. Capital, for several decades, has grown faster than wages, and this means that the top few per cent of the population are accumulating more and more wealth, while the bottom half are making almost no progress at all. Pinker’s counter-argument is that, in absolute terms, even the poorest people are better off than they used to be (Pinker 2018: 97-120). My personal view is that if some people are becoming poorer relative to everyone else, it is little comfort to learn that they are better off than previous generations. I suspect that events like the election of Trump and the vote for Brexit are at least in part an outburst against adverse economic trends.
Unlike the earlier book, Enlightenment Now has attracted a great deal of criticism. One reason is that Pinker focuses a good deal of scorn on western liberal intellectuals, who are overwhelmingly gloomy about society and the way it is going. As Pinker points out, this gloom is not based on evidence, and again and again has been shown to be unjustified (Pinker 2018: 39-52). He has a series of explanations as to why intellectuals argue — wrongly – that things are getting worse. One explanation is the relentless focus of the popular media on violence: no matter what the overall crime rate, if there is a drug-crazed shooting or an atrocity, the media will focus upon it. This distorts our understanding because we use the ‘Availability heuristic’ (Pinker 2018: 41-2). When we readily remember an event, we assume things generally are like that event. So we may be disgusted by what has happened in Syria or the Yemen, or what was done to the Rohingya and regard these as characterising our age. As Pinker argues, however, in previous ages there were far more such atrocities, and they were accepted almost without comment. In addition, gloomy pessimism is often regarded as being far more profound than optimism – even when the optimism is supported by evidence and the pessimism isn’t.
Another reason why Pinker’s book has attracted criticism is because of what he calls ‘counter-Enlightenments’ (Pinker 2018: 29-35). The Enlightenment has suffered a series of reactions from religious and nationalist groups, and also from ideologies of the right and left. These movements do not accept evidence-based arguments and so are uncomfortable with the optimistic message of Pinker’s book. He makes this explicit when, partway through, he writes:
In writing the chapters on progress, I resisted pressure from readers of earlier drafts to end each one by warning, “But all this progress is threatened if Donald Trump gets his way.” Threatened it certainly is (Pinker 2018: 334)
Then he reviews the progress achieved in various fields, and points out that President Trump’s actions and words appear to oppose nearly all of it. In addition, the various nationalist outbursts in Europe could also threaten further progress. There is, Pinker stresses, nothing certain about continued improvements, and so the Enlightenment is well worth defending.
Science and Skepticism
Now the Enlightenment is the basis for two other important features of modern society. One is science, the other skepticism. Pinker (2018: 392-3) points out that science rests on two key ideals. One is that the world is comprehensible to our minds. This is borne out by the success of science. The other assumption is that we should allow the world to tell us what it is like. The traditional sources of belief, and the traditional authorities, are generators of error. Only by carefully formulating theories, and being willing to accept that the evidence may show them to be wrong, can we make scientific progress.
Skepticism, of course, stems from a similar set of ideals. Skeptics examine certain types of belief and question whether they are supported by evidence. It does not matter to skeptics who holds certain beliefs, or whether they stem from one ideology or another. The key question is, does the world tell us that they are true?
Is Pinker right?
Broadly, there are two different ways in which Pinker’s argument can be questioned. Is his evidence for massive, worldwide progress in a whole range of fields justified? And is his stress upon the Enlightenment as a key element in this progress justified? The answer to the first question is almost certainly yes. Pinker makes his sources of information clear, and it is easy to check them. He gets his facts right. The second question is more complex. Norberg (2016) for example, uses the same evidence as Pinker, but traces the improvements to free enterprise rather than the Enlightenment. My personal judgment is that the Enlightenment is a key feature in current progress, but not the only one: If we discard Enlightenment thought, we will suffer in the long run.
As a retiree, I have often worried about what kind of a world we are leaving our children and grandchildren. The short answer appears to be: with some exceptions, a lot better than the world we found. Provided we don’t lose sight of Enlightenment values, the future promises to be much better than the past.
