Book review: How the world thinks by Julian Baggini

Whilst economising during a period without work I thought I would turn to other books in the house to read and review. This is how I came to How the World Thinks: A Global History of Philosophy by Julian Baggini. This is not to say I am uninterested in philosophy but, as a scientist in the Western tradition, philosophy was a substrate on which I worked without thinking.

How the World Thinks aims to provide an outline of the major schools of philosophy around the world, Baggini alludes to the fact that in the Western world university philosophy departments are more accurately described as “Western philosophy” departments. Comparative philosophy, apparently, is not really a thing. Baggini also talks about how “academic” philosophy impacts the culture in which it sits – a process called sedimentation. Baggini cites the 5rd-3th centuries BCE as when the major philosophical traditions were born (know as the Axial Age), when understanding of the world started moving from myth to some sort of reason.

How the World Thinks is divided into four parts and an additional concluding part; these cover the nature of philosophy in different traditions, the nature of the world, who we are and how philosophy impacts the way we live. The text typically covers Far Eastern traditions (China and Japan), India, Islamic and Western traditions with some references to African philosophy. Rather strangely he mentions Russian philosophy in the final part, only to say really he hasn’t mentioned Russian philosophy!

Western philosophy is built around “reason” and nowadays is largely separate from theology, there are empiricist and rationalist schools within this. Empiricists believing on observing the world and building models based on observation, whilst rationalist believe the world can be understood with pure thought. East Asian philosophy is more concerned with a “way” of living in the world which is difficult if not impossible to explain in words. Indian philosophy lies between these two. Interestingly yoga is part of a philosophical tradition which sees it as a way of better seeing how the world really is.

The next part of the book concerns the processes that govern the world: time, karma, emptiness, naturalism, unity, and reductionism. Karma is a particularly Indian concept, and is linked by Baggini to the caste system which DNA evidence dates back to the 6th century AD. East Asian philosophy is more concerned with emptiness / nothingness then Western philosophy – it struck me reading The First Astronomers that Australian Aboriginal constellations include the absence of stars into their constellations. Naturalism, a regard for nature which links the natural world to the human, is stronger in East Asian philosophies – Chinese art incorporated natural scenes long before Western art. Islamic philosophy is strong on unity, whilst Western philosophy likes reductionism.

Part 3 concerns the self, contrasting the East Asian view of the self which is defined in relationship to others, similarly in Africa, with the indivisible, individualistic self of the West. There is even the idea that the self does not exist, as such. Baggini refers to the indivisible self as “atomistic” which harks back to the ancient Greek definition but for a modern scientist this is a bit confusing because an atom is a very different thing. Indian philosophy thinks in terms of a self that is reborn but need not hold any recollection of previous selves. Perhaps not made explicit in this part but one gets the feeling that other philosophies have a strong sense of being concerned with individual self-improvement, by acting in the right way, leading the right life one improves through each rebirth.

The final part of the book concerns how the world lives, how the philosophy discussed in earlier chapters is reflected in culture. This starts with a consideration of the idea of “harmony” in China, this can have elements of hierarchy and misogyny. Although Baggini highlights that it is understood that hierarchy is not bad in all cases, or even most. There is a chapter on “virtue” which as much as anything highlights that the meanings of words when translated can shift. We might think about the importance of “ritual” in Far Eastern cultures but equally we could call it “cultural grammar” which has different connotations in English .

I found How the World Thinks straightforward enough to read, the chapters are a convenient size and the style is readable. It also thought provoking, in that it challenges the deepest assumptions about the way I lead my intellectual life – in some ways it parallels The First Astronomers by Duane Hamacher in this respect.

Book review: Broad Band by Claire L. Evans

Broad Band by Claire L. Evans book cover. Cream background with a silhouette of a woman made from circuit boards

This review is of Broad Band by Claire L. Evans, subtitled The Untold Story of the Women Who Made the Internet. It is arranged thematically with each chapter focusing on a couple of women moving in time from the first chapter, about Ada Lovelace in the 19th century, through to the early years of the 21st century. The first part of the book covers the early period of computing up to the mid-sixties, the second part the growth of networked computing through the seventies and eighties with the final part covering the rise of the World Wide Web and services devoted to women.

The first chapter introduces us to Ada Lovelace, sometimes heralded as the first programmer which is a somewhat disputable claim. More importantly she was clearly a competent mathematician and excelled in democratising and explaining the potential of the mechanical computing engines that Charles Babbage was trying, and largely failing, to build. More broadly this chapter covers the work of the early human “computers”, who were often women, employed to carry out calculations for astronomical or military applications. Following on from this role, by 1946 250,000 women were working in telephone exchanges (presumably in the US).

Women gained this role as “computers” for a range of reasons. In the 19th century it was seen as acceptable work for educated women whose options were severely limited – as they would be for many years to come, excepting war time. The lack of alternatives meant they were very cheap to employ. Under the cover of this apparently administrative role of “computer” women made useful, original contributions to science albeit they were not recognised as such. Women were seen as good at this type of meticulous, routine work.

When the first electronic computers were developed in the later years of the Second World War it was unsurprising that women were heavily involved in their operation partly because of their previous roles, and partly because men had been sent to fight. There appears to have been an attitude that the design and construction of such machines was men’s work and their actual use, the physical act of programming was women’s work – often neglected by those men that built the machines.

It was in this environment that the now renowned Grace Hopper worked. She started writing what we would now describe as compilers to make the task of programming computers easier. She was also instrumental in creating the COBOL programming language, reviled by computer scientist in subsequent years but comprising 80% of the world’s code by the end of the 20th century. The process that Hopper used to create the language, a committee involving multiple companies working towards a common useful goal, looks surprisingly modern.

In the sixties there was a sea-change for women in computing, it was perceived that there was a shortage of programmers and the solution was to change programming into an engineering science which had the effect of gradually pushing women out of computing through the seventies. It was at this time that the power of computer networks started to be realised.

The next part of the book covers networking via a brief diversion into mapping the Mammoth Cave system in Kentucky which became the basis of the first network computer game: Colossal Cave Adventure. I was particularly impressed by Project One, a San Francisco commune which housed a mainframe computer (a Scientific Data Systems 940) which had been blagged from a company by Pam Hardt-English. In the early seventies it became the first bulletin board system (BBS) – a type of system which was to persist all the way through to the creation of the World Wide Web (and beyond). Broad Band also covers some of the later bulletin board systems founded by women which evolved into women’s places on the Web, BBS were majority male spaces for a long time. In the meantime Resource One also became the core of the San Francisco Social Services Referral Directory which persisted through until 2009, this was a radical innovation at the time – computers used for a social purpose outside of scientific or military applications.

The internet as we know it started with ARPANET in 1969. Broad Band covers two women involved in the early internet – Elizabeth (Jake) Feinler who was responsible for the Resource Handbook – a manually compiled directory of computers, and their handlers, on ARPANET. This evolved, under her guidance, to become the WHOIS service and host.domain naming convention for internet addresses. The second woman was Radia Perlman, who invented the Spanning Tree Protocol for ethernet whilst at DEC in 1984.

This brings us, in time, to the beginning of the World Wide Web. The World Wide Web grew out of the internet. Hypertext systems had been mooted since the end of the Second World War but it wasn’t until the eighties that they became technically feasible on widely available hardware. Broad Band cites British Wendy Hall and Cathy Marshall at Rank Xerox as contributors to the development of hypertext systems. These were to be largely swept away by Tim Berners-Lee’s HTML format which had the key feature of hyperlinking across different computers even if this made the handling of those links prone to decay – something handled better by other non-networked hypertext systems. The World Wide Web grew ridiculously quickly in the early nineties. Berners-Lee demonstrated a rather uninspiring version at HyperText ’91 and by HyperText ’94 he was keynote speaker.

There is a a brief chapter devoted to women in gaming. Apparently Barbie Fashion Designer sold 600,000 units in 1996 more than Doom and Quake! There was a brief period when games were made very explicitly for girls – led to a degree by Brenda Laurel who had done extensive research showing boys strive for mastery in games, whilst girls were looking for a collaborator to complete a task. These ideas held sway for a while before a more diverse gaming market took hold which didn’t divide games so much by gender.

It is tempting for me to say that where women have made their mark in computing and the internet is in forming communities, communicating the benefits of technology and making them easier to use – in a reprise of the early pioneering women in science – because that is what women are good at. However, this is the space in which women have been allowed by men – it is not a question of innate ability alone.

I found this book really interesting, it is more an entry point into the topic of women in computing than a comprehensive history. It has made me nostalgic for my computing experiences of the eighties and nineties, and I have added a biography of Grace Hopper to my reading list.

Book review: Foreign Bodies: Pandemics, Vaccines and the Health of Nations by Simon Schama

My next review is of Foreign Bodies: Pandemics, Vaccines and the Health of Nations by Simon Schama.

The book is divided into three parts, covering smallpox, cholera and bubonic plague – in its late 19th century manifestation – and how vaccines were developed and deployed for these diseases. Waldemar Haffkine features heavily in the chapters on cholera and bubonic plague, for which he invented and delivered vaccines, and in some senses this is his biography albeit somewhat unfocussed with much additional material.

The first part covers the introduction of inoculation for smallpox to Western Europe in the early 18th century. This a process whereby a small quantity of the material from a smallpox pustule is introduced to small cuts in the skin of a patient who then falls mildly ill with the disease but is protected from further more serious infection. Voltaire appears in this section as a hook for some of the discussion – he was one of the early promoters of inoculation in France.

Terms are a bit fluid in this area but inoculation refers to the use of the live, unaltered bacteria/virus whilst vaccination refers to the use of a vaccine which is based on a weakened or even partial version of the disease causing micro-organism.

Smallpox was a serious disease in the 18th century, having apparently mutated to a more virulent, deadly form in the mid-17th century. This newer variant killed as many as 1 in 6 of those infected with many of those surviving showing significant scarring. It was indiscriminate, killing royalty as well as paupers. The inoculation process had been used by at least some communities in the Middle East, Africa and South America. The first chapter in this section is largely about the introduction of the idea of inoculation to polite Western European society. This met with some resistance – inoculation did not fit with the then current model of the smallpox disease (essentially the side effect of a bodily purging process), and it challenged the medical establishment coming as it did from a “foreign” country and, worse than that, was often practiced by women!

The second of the smallpox chapter covers the commercialisation of the inoculation process during the 18th century. This typically involved upselling preliminary treatments and post-inoculation care which was largely superfluous. It is interesting though that as part of this process the first clinical trials were conducted to test the efficacy of the process.

The second part of the book, on cholera, features Adrien Proust, father of Marcel Proust. Adrien Proust would become very involved in creating international the first public health organisations. Cholera had come to Europe around 1817 with pandemics killing many thousands recurring through the century. Proust senior had been a young doctor in the 1854 outbreak in Paris as a hospital doctor he would have seen 40% of patients die from this disease. At the time the cause of cholera was not known, it was assumed that it was a result of “filth” and unsanitary living conditions. This perhaps explains some of the Victorian efforts to install sewers and water systems, as well as the fact that living in crowded insanitary cities was simply unpleasant.

In the case of cholera, which is a bacterial infection discovered (quietly) by Filippo Pacini in 1854 and more famously by Robert Koch in 1883, sanitation and disinfection measures are a reasonable approach which has some benefits. There was commercial opposition to seeing cholera as an infection because that implied quarantines and the like which had a commercial impact. This attitude was to recur in the subsequent bubonic plague outbreaks in Indian and China which has more serious consequences since dirty water has no bearing on plague transmission. In fact we saw this argument regarding the COVID-19 restrictions.

It is in this part we first meet Waldemar Haffkine, born into a Jewish family in Odessa in 1860. He trained as a biologist working under Ilya Mechnikov, who would later win a Noble Prize for his work on immunity. Haffkine went on to the Pasteur Institute in Paris (Pasteur was still alive at this point), where he developed a vaccine for cholera. Haffkine had a an extensive file with the authorities in Odessa as a result of his activism in the defence of the Jewish community against repeated pogroms.

He tested his vaccine in India with minimal support from the colonial medical services. Reading between the lines it looks like his expenses claims were a key historical resource. To a degree he used the Indian population as one amenable for doing controlled trials of the vaccine due to their living conditions, and their status in the colonial system.

The part of the book on bubonic plague is a repeat of the chapters on cholera with Haffkine involved in the discovery of the plague bacillus, and the development and deployment of the vaccine, particularly in India. Here the story diverges a bit, the colonial response to plague was to apply sanitation measures up to and including burning down houses where infections had occurred. This, naturally, angered the local population and played some part in the rise of Indian nationalism.

Haffkine’s medical career was to effectively come to an end in the Indian plague vaccination programme. A vial of vaccine that had been produced in the facility he led was contaminated with tetanus leading to the death of nineteen vaccine recipients. The colonial Indian medical authorities were quick to place the blame on Haffkine although later investigations showed that the vial was most likely contaminated “in the field” (literally) and so was not at all Haffkine’s responsibility. He was eventually notationally exonerated with the support of Sir Ronald Ross (who won a Noble prize for his work on the transmission of malaria) but the damage was done and after some work on a typhoid vaccine he gave up his medical work aged 54.

Haffkine, in his later years, returned to his Jewish roots – arguing the case for Orthodox Judaism, and supporting a movement to make Crimea an area for training Jews in agriculture with a view to moving to Palestine. After the Russian revolution Jews no longer faced pogroms on the basis of their religion, they experienced persecution because the Soviet Union did not want anyone, regardless of religion practicing their religion.

I have mixed feelings about this book, it feels like it is trying to be several things at once – a history of vaccination for smallpox, cholera and bubonic plague but also a biography of Waldemar Haffkine with substantial chunks of not entirely relevant material also added. The long chapters don’t suit my reading style very well. At one point Schama manages a half-page sentence which I don’t think I’ve seen before in English! The book is clearly well-researched and written with some style but it doesn’t feel like a book to be read by the pool.

Book review: Femina by Janina Ramirez

In my history thread of reading, Femina by Janina Ramirez is up next. The subtitle, A New History of the Middles Ages, Through the Women Written Out of It, is as good a summary as one would like. Through nine chapters it relates the stories of women from the 7th century through to the 15th century. The earliest chapter relies entirely on archaeological evidence with later chapters mainly documentary but with some reference to historical objects.

The introductory chapter highlights that medieval women, such as Joan of Arc and Julian of Norwich influenced the suffragettes, so their existence was not unknown. It is fair to say that medieval women have not been subject of a huge amount of academic interest.

Subsequent chapters typically focus on one woman but include some material on other similar or related women. The chapters progress chronologically.

A recurring theme is the spread of the Catholic Church through the medieval period, and the role of women in that spread. First, bearing jewelry with secret Christian symbols but later as abbesses – in this period it seemed common for a monastery, for monks, and a convent, for nuns, to be paired. The position of abbess was quite senior, and providing an opportunity for study. The Reformation in the first half of the 16th century took away this route to power for women.

As is my custom I will provide a short summary of the chapters:

Movers and Shakers – the “Loftus princess burial” in North East England in the 7th century. It represents a transitional burial incorporating pre-Christian grave goods – in a Christian cemetery where grave goods are typically not found. It also considers the role of women like Queen Bertha of Kent and Hilda of Whitby in the development of the early Christian church in England.

Decision makers – the women of the British kingdoms prior to the “Viking” invasion in the second half of the 9th century. Cynethryth, Queen of the Mercians, features heavily – she ruled with her husband, Offa, until he died, and then in her own right. Cynethryth is unique as a women in England found on coinage of this period.

Warriors and Leaders – the Birka Warrior, a burial in a settlement near Stockholm – occupied for a period of 200 years. They were buried with weapons but were recently identified as a woman rather than a man. Obviously this caused some controversy but other sources suggest that there were at least some military women in this period and other burials on the site suggested that women were also tradespeople.

Artists and patrons – the Bayeux Tapestry, and the team of women believed to have made it – it turns out that it isn’t King Harold getting the arrow in the eye – once again my childhood history knowledge is false!

Polymaths and scientists – this chapter focusses on Hildegard of Bingen (1098-1179). She was an abbess and wrote widely on a range of topics including science and medicine as well as composing music. Her correspondence network included several popes.

Spies and Outlaws – the Cathars in southern France – who were subject to the Albigensian Crusade for heresy in the early 13th century. This was in a time when the Inquisition was only part-formed and local arrangements were more important than the central view. Women appear in the records of the Inquisition, and could be preachers in the Cathar religion.

Kings and diplomats – Jadwiga, the only female king of Poland, a member of the Europe-wide royal families. She introduced the Catholic Church to Poland, founded a University in Krakow, the first in Poland. She died following childbirth at the age of 26. In common with the Decision Makers chapter it shows how marriage was used as a tool of diplomacy in medieval Europe but with women playing some role in organising these partnerships – not simply pawns moved around a board by men.

Entrepreneurs and influencers – the chance survival of The Book of Margery Kempe – the first autobiography in English, written around 1440. Margery Kempe was from a relatively important family in Kings Lynn. She seems like quite a character, reporting a wide range of business enterprises, and religious visions as well as a pilgrimage to Jerusalem.

The final chapter touches on diversity, looking at the ethnicity of Londoners around the time of the Black Death – it shows (on the basis of 41 skeletons) that London in 1350 was about as diverse as modern London. There is also a single court account, elided in the official translation, relating to someone who might now be considered transgender.

Unrelated to gender, Femina highlights how cosmopolitan and connected medieval England was to Europe, and even Asia.

One thing that struck me from this book is that history is viewed through a glass darkly. Across the span of the 600 or so years from the latest of the women described in this book to the present day a great deal can happen. The first is that women are simply not written about, although this book shifts the balance a bit, it is clear were not generally considered the equals of men in the Middle Ages but they were more important than we perhaps currently believe.

More insidiously history is continually re-written by (usually) men with their own axe to grind, or simply a story to tell. An example of this is the “invention” of the Vikings in the 19th century, including their horned helmets which were popularised by a staging of The Ring of the Nibelung in 1876. The suppression of women’s stories started not long after the end of this book, in the 16th century or so.

This is without considering the amount of material simply lost over the span of 600 years.

I found Femina really readable, the chapters all start with some scene setting written in a more fictional style, the chapters provide self-contained stories – it is easy to see this being made into a TV series. I think the biggest takeaways for me were how important at least some women were in the Middle Ages, and how distorted our view of the past is by the historians (and wider society) of the intervening period.

Book review: The Earth Transformed by Peter Frankopan

frankopanIt is rare that I am menaced by the sheer size of a book but The Earth Transformed by Peter Frankopan has done this to a degree. The Silk Roads, by the same author is similarly massive. So in a break from my usual habit I am going to review as I read.

The book is about the interplay of climate and humanity, and how humanity impacts the environment with an attempt to cover history across the world rather than focussing on Western Europe.

The extensive footnotes for this book are found in a separate downloadable pdf.

0 – Introduction – Frankopan is a year younger than me – born in 1971, and his early memories were shaped by news reports of acid rain, the fear of nuclear winter and Chernobyl – all stark demonstrations of man’s potential impact on the environment.

1 – The World from the Dawn of Time(4.5bn-7m BC) – The earth’s environment has always been changing, in deep time there was a much lower concentration of oxygen in the atmosphere. Those animals we see around us are the result of evolution through multiple cataclysmic environmental events.

2 – On the origins of our species (7m BC-12,000BC) – Climate change in central Africa and growing social groups led to speciation of the hominid group. We started large scale manipulation of the environment – managing forests with fire – 65,000 years ago.

3 – Human interactions with Ecologies (c.12000-c.3500BC) – End of the Younger Dryas and the start of the Holocene is a key point for civilisations, the climate becomes more benign and stable and larger settlements start to grow.

4 – The first cities and trade networks (c3500-c2500 BC) – the first cities are founded, and arguably the first anthropogenic climate change takes place. With cities came hierarchies, ownership and vulnerability to shocks and disease.

5 – On the risks of living beyond one’s means (2500BC-c.2200BC) – One such shock is the great drought of 2200BC, often seen as a global phenomena but actually rather complicated with different regional effects and an impact which was perhaps most obvious on the ruling class.

6 – The first age of connectivity (c.2200-c.800BC) – the environment provides resources unevenly, and so trade is necessary as societies become more sophisticated, these trade networks lead to interdependence so when one society falls others are impacted. The trade is not just in goods but also in ideas.

7 – Regarding Nature and the Divine (c1700-c.300BC) – Religions which we still see today arose several hundred years BC, and many of them made references to the environment. The ruler was often an intermediary to the gods/control of the weather – rain being particularly important. Even in this time there were exhortations to preserve the environment.

8 – The Steppe Frontier and Formation of Empires (c.1700-c.300BC) – the Eurasian steppes provided a catalyst for the growth of empires in the neighbouring region, alongside the domestication of the horse in about 3000BC. This combination provided rapid transport, and the flatness of the terrain made expansion easy. There is also an interplay between nomadic and pastoral peoples.

9 – The Roman Warm Period (c.300BC-AD c.500) – the Roman Empire grew at a time of benign and stable climatic conditions – and fell when those climatic conditions changed. Contemporary writers noted the pollution in Rome and other big cities. We can see the lead of the Roman Empire in Greenland ice cores.

10 – The Crisis of Late Antiquity (AD c.500-c.600) – the decades from 530AD saw multiple volcanic eruptions leading to global cooling, food shortages, and the rise of disease (the Justinian plague) and the fall of empires.

11 – The Golden Age of Empire (c.600-c.900) – the Prophet Mohammad’s agreement with the ruling elite in Mecca in 628AD provided an Arab identity that grew to an Empire stretching across North Africa and into Spain. Trade grows with sub-Saharan Africa. These patterns are replicated in the Americas and the Far East. Literacy grew in the eighth century with the introduction of paper from China. Empires started to decline in the 9th century as another warmer drier period started.

12 – The Medieval Warm Period (c.900-c.1250) – the Medieval Warm Period was both warm, and stable with unusually low levels of volcanic activity. During this time there was a large growth in global population, and Northern Europe saw significant growth. This growth was a result of improvements in crops and technology, as well as the benign climate.

13 – Disease and the formation of a New World (c.1250-c.1450) – the 13th century saw the rise of the Mongol empire, under Genghis Khan, stimulated by wetting weather in the steppe leading to more productive pasture when other areas were suffering drought. But the wet weather and the extensive trade networks of the Empire led to the rise of Black Death. Interesting parallels between post-Plague and post-1918 influenza Europe – the roaring twenties.

14 – On the expansion of Ecological Horizons (c.1400-c.1500) – the 14th and 15th century saw the fall of some of those empires that rose during the earlier more benign and stable weather, more driven by the instability of large empires than by climate change. It also saw the European "exploration" of the world and the large scale transport of plant and animal species across the world.

15 – The Fusion of the Old and the New Worlds (c.1500-c.1700) – the European "discovery" of the New World introduced a massive migration of flora and fauna around the world, potatoes, tomatoes,chillies from the New World to the Old. Pigs, sheep, goats and cattle from the Old to the New.

16 – On the exploitation of Nature and People (c.1650-c.1750) – the new sugar, tobacco and cotton industries required a large workforce, resistant to malaria, and Africans fitted the bill – this chapter to about slavery.

17 – The Little Ice Age (c.1550-c.1800) – the Little Ice Age has long been known but its magnitude was quite variable around the world, many things have been ascribed to the Little Ice Age but connections and causality are tenuous. The 17th century saw significant developments in military technology and spending on professional armies in Europe. There was also a large rise in urbanisation. Variable weather, uncertain crops hit some countries hard.

18 – Concerning Great and Little Divergences (c.1600-c.1800) – 1600-1800 was the period in which the economies of Europe diverged from those of Asia and Africa, and in Europe the North pulled away from the South. The introduction of the potato to Europe was important, as was maize and manioc (cassava) to Africa.

19 – Industry, extraction and the Natural World (c.1800-c.1870) – markets became truly global with wheat from North America cheaper to ship from Canada to Liverpool than from Dublin to Liverpool. Colonialism was at its height with Britain leading the world and the Americans expelling indigenous people from their own lands.

20 – The Age of Turbulence (c.1870-c.1920) – new resources became ripe for exploitation like rubber, guano and tin. Industrialisation proceeded apace. Concerns about climate began, and the Carrington Event and the Krakatoa eruption started scientists thinking about global impacts. Global pandemics made an appearance for both people and animals.

21 – Fashioning New Utopias (c.1920-c.1950) – the middle years of the 20th century saw a new wave of exploitation with oil, copper, uranium and more recently lithium becoming important resources. Colonialism receded but was replaced by corporate and government interference in states. In the Soviet Union ecological damage, and great human upheaval was driven by the dash to modernise but in a communist rather than capitalist framework.

22 – Reshaping the Global Environment (the mid-Twentieth Century) – the USSR and the USA started large scale environmental modification projects, see Teller’s proposals to use nuclear explosions to change just about anything.

23 – The Sharpening of Anxieties (c.1960-c.1990) – in the sixties the USA and USSR got heavily into weather modification, and the Americans into Agent Orange in Vietnam. The USA programme was conducted in deep secrecy, and when it was revealed there was an outcry which lead to a treaty banning such environmental modification. This led to a wider thaw of Cold War interactions.

24 – On the edge of Ecological Limits (c.1990-today) – the 1990s saw the fall of the Soviet Union and the rise of Industrial China. It also saw the discussions over climate change heating up.

25 – Conclusions – Frankopan’s conclusion is rather gloomy, he highlights how we are failing to act on climate change but then points we may suffer worse consequences from volcanic activity, or an asteroid strike!

There are themes across the whole book, in the environment we see periods of stable climate interspersed by periods of change – particularly driven by volcanic eruptions. From the human side we see the growing scale of civilisations, larger civilisations with more connections are more vulnerable to instability and the fall of other civilisations. We see ever increasing urbanisation and exploitation of the environment at ever greater scale.

Although initially intimidating, I found The Earth Transformed rather readable – perhaps because I saw each chapter as a separate essay.
