Pollution in Pre-Industrial Europe

Pollution in Pre-Industrial Europe

Prime Minister Benjamin Disraeli once described the River Thames as "a Stygian pool, reeking with ineffable and intolerable horrors."

Last week, I wrote about Jason Hickel’s romantic idea that people in the past “lived well” with little or no monetary income. I noted that prior to the Industrial Revolution, clothing was immensely expensive and uncomfortable. The cotton mills changed all that.

As a French historian noted in 1846, “Machine production…brings within the reach of the poor a world of useful objects, even luxurious and artistic objects, which they could never reach before.”

Today, I wish to turn to pollution. It is well known that industrialization helped to pollute the environment, but that does not mean that air and water were clean before factories and mills came along! Compared to today, our ancestors had to endure horrific environmental conditions.

Let’s start with air quality. In the 17th century London, Claire Tomalin observed in Samuel Pepys: The Unequalled Self, “Every household burnt coal … The smoke from their chimneys made the air dark, covering every surface with sooty grime. There were days when a cloud of smoke half a mile high and twenty miles wide could be seen over the city … Londoners spat black.”

In a similar vein, Carlo Cipolla in his book Before the Industrial Revolution: European Society and Economy 1000-1700, quotes from the diary of British writer John Evelyn, who wrote in 1661: “In London we see people walk and converse pursued and haunted by that infernal smoake. The inhabitants breathe nothing but an impure and thick mist, accompanied by a fuliginous and filthy vapour … corrupting the lungs and disordering the entire habit of their bodies.”

The streets were just as dirty. John Harrington invented the toilet in 1596, but bathrooms remained rare luxuries two hundred years later. Chamber pots continued to be emptied into streets, turning them into sewers. To make matters worse, even large towns continued to engage in husbandry well into the 18th century. As Fernand Braudel noted in The Structures of Everyday Life, “Pigs were reared in freedom in the streets. And the streets were so dirty and muddy that they had to be crossed on stilts.”

Lawrence Stone observed in The Family, Sex and Marriage in England 1500-1800 that “In towns in the eighteenth century, the city ditches, now often filled with stagnant water, were commonly used as latrines; butchers killed animals in their shops and threw the offal of the carcases into the streets; dead animals were left to decay and fester where they lay; latrine pits were dug close to wells, thus contaminating the water supply. Decomposing bodies of the rich in burial vaults beneath the church often stank out parson and congregation.”

A “special problem” in London, Stone wrote, was the “poor holes” or “large, deep, open pits in which were laid the bodies of the poor, side by side, row by row. Only when the pit was filled with bodies was it finally covered with earth.” As one contemporary writer, whom Stone quotes, observed, “How noisome the stench is that arises from these holes.” Furthermore, “great quantities of human excrement were cast into the streets at night … It was also dumped into on the surrounding highways and ditches so that visitors to or from the city ‘are forced to stop their noses to avoid the ill smell.’”

According to Stone, “The result of these primitive sanitary conditions was constant outbursts of bacterial stomach infections, the most fearful of all being dysentery, which swept away many victims of both sexes and of all ages within a few hours or days. Stomach disorders of one kind or another where chronic, due to poorly balanced diet among the rich, and the consumption of rotten and insufficient food among the poor.”

Then there was “the prevalence of intestinal worms,” which is “a slow, disgusting and debilitating disease that caused a vast amount of human misery and ill health … In the many poorly drained marshy areas, recurrent malarial fevers were common and debilitating diseases … [and] perhaps even more heart-breaking was the slow, inexorable, destructive power of tuberculosis.”

The situation was no better on the European mainland. In the middle of the 17th century, Queen Anne of Austria and mother of Louis XIV noted that “Paris is a horrible place and ill smelling. The streets are so mephitic that one cannot linger there because of the stench of rotting meat and fish and because of a crowd of people who urinate in the streets.”

In the 19th century, pollution remained a problem. In Inside the Victorian Home: A Portrait of Domestic Life in Victorian England, Judith Flanders noted Waldo Emerson’s observation that “no one … [in England] wore white because it was impossible to keep it clean.” According to Flanders, hair brushes looked “black after once using” and tablecloths were laid just before eating, “as otherwise dust settled from the fire and they became dingy in a matter of hours.”

In 1858, the stench from the River Thames was so bad that “the curtains on the river side of the building were soaked in lime chloride to overcome the smell”. The effort was unsuccessful, with Prime Minister Benjamin Disraeli once fleeing a committee room “with a mass of papers in one hand, and with his pocket handkerchief applied to his nose,” because the stench was so bad. He called the river “a Stygian pool, reeking with ineffable and intolerable horrors.”

Keep in mind that even after the Industrial Revolution had begun, much of the pollution was still non-industrial. Henry Mayhew, an English social researcher and journalist, found that the Thames contained “ingredients from breweries, gasworks, and chemical and mineral manufactories; dead dogs, cats, and kittens, fats, offal from slaughterhouses; street-pavement dirt of every variety; vegetable refuse; stable-dung; the refuse of pig-styes; night-soil; ashes; tin kettles and pans … broken stoneware, jars, pitchers, flower-pots, etc.; pieces of wood; rotten mortar and rubbish of different kinds.”

There can be no doubt that industrialisation did great damage to the environment during the second half of the 19th century. But it also created wealth that allowed advanced societies to build better sanitation facilities, and spurred the creation of an enlightened populace with a historically unprecedented concern over the environment and a willingness to pay for its stewardship through higher taxation.

Fast-forward to 2015 and the BBC reported “more than 2,000 seals have been spotted in the Thames over the past decade … along with hundreds of porpoises and dolphins and even the odd stray whale … There are now 125 species of fish in the Thames, up from almost none in the 1950s.” Similarly, average concentrations of suspended particulate matter in London rose from 390 in 1800 to a peak of 623 in 1891, before falling to 16 micrograms per cubic meters in 2016. Today, air in the capital of the United Kingdom ranks as one of the cleanest among the world’s major cities.

Contemporary evidence clearly shows that the lives of many Western Europeans before industrialisation were, at least by today’s standards, deeply unpleasant. It would be a stretch to conclude that they have “lived well.”

Lessons From Adam Smith’s Edinburgh and Paris

Examining the places where major advances happened is one way to learn about the conditions that foster societal flourishing, human achievement, and prosperity.

Summary: Amidst the turmoil of modern times, evidence reveals significant progress across various metrics, from rising life expectancy to declining global poverty. Cities have emerged as epicenters of innovation and progress throughout history, fostering collaboration, competition, and freedom of thought. By exploring the unique environments of cities like Edinburgh and Paris, where intellectual liberty thrived, Chelsea Follett uncovers the vital role of peace, freedom, and population density in driving human achievement and societal advancement.


This article appeared in Adam Smith Works on 2/8/2024.

Has humanity made progress? With so many serious problems, it is easy to get the impression that our species is hopeless. Many people view history as one long tale of decay and degeneration since some lost, idealized golden age.

But there has been much remarkable, measurable improvement—from rising life expectancy and literacy rates to declining global poverty. (Explore the evidence for yourself). Today, material abundance is more widespread than our ancestors could have dreamed. And there has been moral progress too. Slavery and torture, once widely accepted, are today almost universally reviled.

Where did all this progress come from? Certain places, at certain times in history, have contributed disproportionately to progress and innovation. Change is a constant, but progress is not. Studying the past may hold the secret to fostering innovation in the present. To that end, I wrote a book titled Centers of Progress: 40 Cities that Changed the World, exploring the places that shaped modern life.

The origin points of the ideas, discoveries, and inventions that built the modern world were far from evenly or randomly dispersed throughout the globe. Instead, they tended to emerge from cities, even in time periods when most of the human population lived in rural areas. In fact, even before anything that could be called a city by modern standards existed, progress originated from the closest equivalents that did exist at the time. Why is that?

“Cities, the dense agglomerations that dot the globe, have been engines of innovation since Plato and Socrates bickered in an Athenian marketplace,” urban economist Edward Glaeser opined in his book The Triumph of the City. Of course, he was hardly the first to observe that positive change often emanates from cities. As Adam Smith noted in 1776, “the commerce and manufactures of cities, instead of being the effect, have been the cause and occasion of the improvement and cultivation of the country.”

One of the reasons that progress tends to emerge from cities is, simply, people. Wherever more people gather together to “truck, barter, and exchange,” in Smith’s words, that increases their potential to engage in productive exchange, discussion, debate, collaboration, and competition with each other. Cities’ higher populations allow for a finer division of labor, more specialization, and greater efficiencies in production. Not to mention, more minds working together to solve problems. As the writer Matt Ridley notes in the foreword he kindly wrote for Centers of Progress, “Progress is a team sport, not an individual pursuit. It is a collaborative, collective thing, done between brains more than inside them.”

A higher population is sufficient to explain why progress often emerges from cities, but, of course, not all cities become major innovation centers. Progress may be a team sport, but why do certain cities seem to provide ideal playing conditions, and not others?

That brings us to the next thing that most centers of progress share, besides being relatively populous: peace. That makes sense, because if a place is plagued by violence and discord then it is hard for the people there to focus on anything other than survival, and there is little incentive to be productive since any wealth is likely to be looted or destroyed. Smith recognized this truth, and noted that cities, historically, sometimes offered more security from violence than the countryside:

Order and good government, and along with them the liberty and security of individuals, were in this manner established in cities, at a time when the occupiers of land in the country, were exposed to every sort of violence. But men in this defenceless state naturally content themselves with their necessary subsistence; because, to acquire more, might only tempt the injustice of their oppressors. On the contrary, when they are secure of enjoying the fruits of their industry, they naturally exert it to better their condition, and to acquire not only the necessaries, but the conveniencies and elegancies of life. That industry, therefore, which aims at something more than necessary subsistence, was established in cities long before it was commonly practised by the occupiers of land in the country. […] Whatever stock, therefore, accumulated in the hands of the industrious part of the inhabitants of the country, naturally took refuge in cities, as the only sanctuaries in which it could be secure to the person that acquired it.

Of course, not all cities were or are peaceful. Consider Smith’s own city: Edinburgh. At times, the city was far from stable. But the relatively unkempt and inhospitable locale emerged from a century of instability to take the world by storm. Scotland in the 18th century had just undergone decades of political and economic turmoil. Disruption was caused by the House of Orange’s ousting of the House of Stuart, the Jacobite Rebellions, the failed and costly colonial Darien Scheme, famine, and the 1707 Union of Scotland and England. It was only after things settled down and the city came to enjoy a period of relative peace and stability that Edinburgh rose to reach its potential. Edinburgh was an improbable center of progress. But Edinburgh proves what people can accomplish, given the right conditions.

During the Scottish Enlightenment centered in Edinburgh, Adam Smith was far from the only innovative thinker in the city. Edinburgh’s ability to cultivate innovators in every arena of human achievement, from the arts to the sciences, seemed almost magical.

Edinburgh gave the world so many groundbreaking artists that the French writer Voltaire opined in 1762 that “today it is from Scotland that we get rules of taste in all the arts, from epic poetry to gardening.” Edinburgh gave humanity artistic pioneers from the novelist Sir Walter Scott, often called the father of the historical novel, to the architect Robert Adam who, together with his brother James, developed the “Adam style,” which evolved into the so‐​called “Federal style” in the United States after Independence.

And then there were the scientists. Thomas Jefferson, in 1789, wrote, “So far as science is concerned, no place in the world can pretend to competition with Edinburgh.” The Edinburger geologist James Hutton developed many of the fundamental principles of his discipline. The chemist and physicist Joseph Black, who studied at the University of Edinburgh, discovered carbon dioxide, magnesium, and the important thermodynamic concepts of latent heat and specific heat. The anatomist Alexander Monro Secondus became the first person to detail the human lymphatic system. Sir James Young Simpson, admitted to the University of Edinburgh at the young age of fourteen, went on to develop chloroform anesthesia.

Two of the greatest gifts that Edinburgh gave humanity were empiricism and economics. The influential philosopher David Hume was among the early advocates of empiricism and is sometimes called the father of philosophical skepticism. And by creating the field of economics, Smith helped humanity to think about policies that enhance prosperity. Those policies, including free trade and economic freedom that Smith advocated, have since helped to raise living standards to heights that would be unimaginable to Smith and his contemporaries.

That brings us to the last but by no means least secret ingredient of progress. Freedom. Centers of progress during their creative peak tend to be relatively free and open for their era. That makes sense because simply having a large population is not going to lead to progress if that population lacks the freedom to experiment, to debate new propositions, and to work together for their mutual benefit. Perhaps the biggest reason why cities produce so much progress is that city dwellers have often enjoyed more freedom than their rural counterparts. Medieval serfs fleeing feudal lands to gain freedom in cities inspired the German saying “stadtluft macht frei” (city air makes you free).

That adage referred to laws granting serfs liberty after a year and a day of urban residency. But the phrase arguably has a wider application. Cities have often served as havens of freedom for innovators and anyone stifled by the stricter norms and more limited choices common in smaller communities. Edinburgh was notable for its atmosphere of intellectual freedom, allowing thinkers to debate a wide diversity of controversial ideas in its many reading societies and pubs.

Of course, cities are not always free. Authoritarian states sometimes see laxer enforcement of their draconian laws in remote areas, and Smith himself viewed rural life as in some ways less encumbered by constraining rules and regulations than city life. But as philosophy professor Kyle Swan previously noted for Adam Smith Works:

Without denying the charms and attractions Smith highlights in country living, let’s not forget what’s on offer in our cities: a significantly broader range of choices! Diverse restaurants and untold many other services and recreations, groups of people who like the same peculiar things that you like, and those with similar backgrounds and interests and activities to pursue with them — cities are (positive) freedom enhancing.

The same secret ingredients of progress—people, peace, and freedom—that helped Edinburgh to flourish during Smith’s day can be observed again and again throughout history in the places that became key centers of innovation. Consider Paris.

As the capital of France, Paris attracted a large population and became an important economic and cultural hub. But it was an unusual spirit of freedom that allowed the city to make its greatest contributions to human progress. Much like the reading societies and pubs of Smith’s Edinburgh, the salons and coffeehouses of 18th‐​century Paris provided a place for intellectual discourse where the philosophes birthed the so‐​called Age of Enlightenment.

The Enlightenment was a movement that promoted the values of reason, evidence‐​based knowledge, free inquiry, individual liberty, humanism, limited government, and the separation of church and state. In Parisian salons, nobles and other wealthy financiers intermingled with artists, writers, and philosophers seeking financial patronage and opportunities to discuss and disseminate their work. The gatherings gave controversial philosophers, who would have been denied the intellectual freedom to explore their ideas elsewhere, the liberty to develop their thoughts.

Influential Parisian and Paris‐ based thinkers of the period included the Baron de Montesquieu, who advocated the then‐​groundbreaking idea of the separation of government powers and the writer Denis Diderot, the creator of the first general‐​purpose encyclopedia, as well the Genevan expat Jean‐​Jacques Rousseau. While sometimes considered a counter‐​Enlightenment figure because of his skepticism of modern commercial society and romanticized view of primitive existence, Rousseau also helped to spread skepticism toward monarchy and the idea that kings had a “divine right” to rule over others.

The salons were famous for sophisticated conversations and intense debates; however, it was letter‐​writing that gave the philosophes’ ideas a wide reach. A community of intellectuals that spanned much of the Western world—known as the Republic of Letters—increasingly engaged in the exchanges of ideas that began in Parisian salons. Thus, the Enlightenment movement based in Paris helped spur similar radical experiments in thought elsewhere, including the Scottish Enlightenment in Edinburgh. Smith’s many exchanges of ideas with the people of Paris, including during his 1766 visit to the city when he dined with Diderot and other luminaries, proved pivotal to his own intellectual development.

And then there was Voltaire, sometimes called the single most influential figure of the Enlightenment. Although Parisian by birth, Voltaire spent relatively little time in Paris because of frequent exiles occasioned by the ire of French authorities. Voltaire’s time hiding out in London, for example, enabled him to translate the works of the political philosopher and “father of liberalism” John Locke, as well as the English mathematician and physicist Isaac Newton. While Voltaire’s critiques of existing institutions and norms pushed the boundaries of acceptable discourse beyond even what would be tolerated in Paris, his Parisian upbringing and education likely helped to cultivate the devotion to freethinking that would come to define his life.

By allowing for an unusual degree of intellectual liberty and providing a home base for the Enlightenment and the far‐​ranging Republic of Letters, Paris helped spread new ideas that would ultimately give rise to new forms of government—including modern liberal democracy.

Surveying the cities, such as Edinburgh and Paris, that built the modern world reveals that when people live in peace and freedom, their potential to bring about positive change increases. Examining the places where major advances happened is one way to learn about the conditions that foster societal flourishing, human achievement, and prosperity. I hope that you will consider joining me on a journey through the book’s pages to some of history’s greatest centers of progress, and that doing so sparks many intelligent discussions, debates, and inquiries in the Smithian tradition about the causes of progress and wealth.

1,000 Bits of Good News You May Have Missed in 2023

A necessary balance to the torrent of negativity.

Reading the news can leave you depressed and misinformed. It’s partisan, shallow, and, above all, hopelessly negative. As Steven Pinker from Harvard University quipped, “The news is a nonrandom sample of the worst events happening on the planet on a given day.”

So, why does Human Progress feature so many news items? And why did I compile them in this giant list? Here are a few reasons:

  • Negative headlines get more clicks. Promoting positive stories provides a necessary balance to the torrent of negativity.
  • Statistics are vital to a proper understanding of the world, but many find anecdotes more compelling.
  • Many people acknowledge humanity’s progress compared to the past but remain unreasonably pessimistic about the present—not to mention the future. Positive news can help improve their state of mind.
  • We have agency to make the world better. It is appropriate to recognize and be grateful for those who do.

Below is a nonrandom sample (n = ~1000) of positive news we collected this year, separated by topic area. Please scroll, skim, and click. Or—to be even more enlightened—read this blog post and then look through our collection of long-term trends and datasets.

      A Reduction in the Proportion of Africans Living in Shanty Towns

      “According to the United Nations Development Programme (UNDP), a shanty town is a disadvantaged part of a city characterised by very unhealthy housing built by the inhabitants from salvaged materials, extreme poverty and no rights or security of tenure. According to the World Bank, over 60% of Africa’s urban population now lives in shanty towns. These almost 285 million urban dwellers represent 60% of Africa’s urban population. In 2003, Africans living in shanty towns made up 71.9% of the urban population.”

      Introducing Centers of Progress: 40 Cities That Changed the World

      “Cities, the dense agglomerations that dot the globe, have been engines of innovation since Plato and Socrates bickered in an Athenian marketplace,” as urban economist Edward Glaeser explains in his book The Triumph of the City.

      Athens’s storied breakthroughs in philosophy are but one example of how cities have often been the sites of pivotal advances throughout history. Kyoto gave us the novel. Bologna gave us the university. Florence gave us the Renaissance. Paris gave us the Enlightenment. Manchester gave us the Industrial Revolution. Los Angeles gave us cinema. Postwar New York gave us modern finance . . . the list goes on. As Glaeser also notes, “Wandering these cities—whether down cobblestone sidewalks or grid-cutting cross streets, around roundabouts or under freeways—is to study nothing less than human progress.”

      If you’re not able to travel to each of these extraordinary cities, perhaps the next best thing is to embark on a virtual tour from the comfort of your home. To that end, I wrote a book surveying 40 of history’s greatest urban centers, showcasing each city at a moment in time when it notably contributed to progress.

      Centers of Progress: 40 Cities That Changed the World offers a fact-filled yet accessible crash course in global urban history, spanning from the agricultural revolution to the digital revolution. This book affirms the importance of cities to the story of human progress and innovation by shining a spotlight on some of the places that have helped create the modern world.

      The book’s chapters can guide you through the Library of Alexandria, the stock exchange of Dutch Golden Age-era Amsterdam, and the pubs of Edinburgh during the Scottish Enlightenment, all in an afternoon.

      Centers of Progress “takes the reader on a time-travel cruise through the great flash points of human activity to catch innovations that have transformed human lives” at their moment of invention, according to writer Matt Ridley in the insightful foreword that he kindly provided. Come explore Agra as the Taj Mahal was erected and Cambridge as Isaac Newton penned the Principia. Meet engineers in Ancient Rome, Silk Road merchants in Tang Dynasty Chang’an, music composers in 19th-century Vienna, and Space Age flight controllers in Houston.

      Learning about past achievements may even hold the secret to fostering innovation in the present.

      As I note in the book, “Although there are some exceptions, most cities reach their creative peak during periods of peace. Most centers of progress also thrive during times of relative social, intellectual, and economic freedom, as well as openness to intercultural exchange and trade. And centers of progress tend to be highly populated. . . . Identifying those common denominators among the places that have produced history’s greatest achievements is one way to learn what causes progress in the first place. After all, change is a constant, but progress is not.”

      From the fall of the Berlin Wall to Hong Kong’s transformation from a war-ravaged “barren island” into a prosperous metropolis, many of the stories featured in Centers of Progress hold valuable lessons about the importance of ideas, people, and freedom. I hope that you will consider joining me on a journey through the book’s pages to some of history’s greatest centers of progress.
