Why do wars start? How can we avoid them? Do countries wage wars whenever it suits their own goals? Or are wars a product of failed understanding and military madmen?
These are questions at the centre of the study of war and peace. But for too long, the field of international relations has answered them by scavenging data from European history alone. To better understand the human capacity for peace, we need to understand military history more broadly.
Or so argues David C. Kang, a professor at the University of Southern California.
A Korean American scholar of international relations, Kang argues that the histories of China, Japan, Korea, and Vietnam give us lessons that no reading of European countries could: lessons about neighbouring countries living in peace for centuries. Yes, there was violence. At times, there was war. But peace between these countries prevailed for stunningly long periods. And contrary to standard theories of war and peace, this wasn’t achieved by a “balance of powers”, nor by an inability to sustain military operations.
But is this too peaceful a picture of East Asian history? Didn’t China keep up bullying Vietnam? What about the epic wars started by Japan? What about the Mongols, the Great Wall, and China’s expansion on its Western frontier? And what, if anything, can this tell about war and peace in the 21st Century? Doesn’t the “Thucydides trap” make a war between the US and China inevitable?
We discuss these and many other questions in this fascinating episode.
I am particularly glad to bring you this episode as it brings together two of the major themes on the show this fall: the study of war and peace and the study of Asian history.
Co-hosting again was Jordan Schneider from ChinaTalk.

Our ancestors did not wage war. Warfare emerged only when humans started settling down and storing food. Indeed, some modern hunter-gatherers still enjoy the peaceful existence that once was the natural state of our species.
Or so argued Douglas P. Fry, my guest in episode 8. I found many of his arguments convincing. For example, ancient cave art is surprisingly void of depictions of warfare. You can hear many more of his arguments in that episode, titled "Is War Natural For Humans?"
But not all scholars agree. Far from it. And I owe a voice to the other side of the debate. So here is an episode with one of the most thoughtful voices arguing for a deeper origins of war.
Luke Glowacki is a professor of anthropology at Boston University, where teaches courses on the evolution of war. And he believes that war has very ancient origins, indeed.
We had a very stimulating conversation, discussing topics such as:
(03:00) The debate: What can we all agree on? And what are the disagreements?
(12:10) Hunter-gatherers: Are they peaceful? And are they any good as models of the past?
(25:55) Archaeology: Cave paintings and broken bones
(34:55) Primatology: Chimpanzees and bonobos
(46:40) Implications: What can we learn from all this?
As always, we finish with my guest's reflections on humanity.

Daron Acemoglu has been awarded the 2024 Nobel-prize for Economic Science. This is a great testament to his impressive career. But the award was given for his early work on global inequality, together with Johnson and Robinson. The Swedish Riksbank did not pay attention to his new work on inequality within rich countries. Should we? And is his new theory even consistent with the old?
I got to ask this from Acemoglu during our 2023 interview. I thought this would be a good time to re-post his answer. In this highlight, we also discuss:
The hidden tragedy behind growing wages Is automation the problem? Why we need a more "pro-human" direction of technology Lessons from (an imperfect) Germany Why fixing the economy starts from celebrating humanityIf you want to enjoy the full show, head to episode 26 of this feed.

You are given 20 dollars in cash. You can use it as you wish, but with one condition: you have to use it to treat yourself.
Now imagine getting another 20 dollars next week. This time, the rules have changed: you must use the money to treat someone else.
Which do you think will make you feel better?
Contrary to many people's predictions, we tend to feel much better after spending the money on others. Whether we act it out or not, it seems that the human psyche is fine-tuned for generosity.
Why? And why am I so confident about this anyway? Is the effect really a universal part of humanity? Does it take place across cultures and ages? What about those who give too much and experience a burnout? And if giving feels good, why don’t we do it more?
Lara Aknin is one of the world’s leading scientists working on generosity. Her master’s thesis led to a publication in Science — something I used to think was undoable — and she has studied generosity ever since.
In this episode, Prof Aknin and I discuss:
The original evidence / Cross-cultural research / Alternative explanations / Do toddlers like giving? / Why does generosity feel good? / Why don’t we give more then? / What about giving too much (or caring for someone with dementia)? / Selfish generosity?
As always, we finish with my guest's reflections on humanity.

Where is China today? Will its rise continue to benefit the vast majority of its population? Or is Xi Jinping's increasingly repressive government committing one of the biggest blunders of modern history?
This is the final episode in the China-trilogy, the product of hours of conversations I've had with ChinaTalk's Jordan Schneider and MIT professor Yasheng Huang.
In part 1, we discussed the deep currents of Chinese history, shaping the country's destiny from its early technological lead to its more recent decline and stagnation. In part 2, we discussed China during and after Mao, trying our best to explain the Chinese economic miracle. In this final episode, we discuss questions about China's present and future, guided by lessons from its recent past. We touch upon issues such as:
The causes and consequences of Xi Jinping's rise Why both Chinese leaders and Western observers misunderstand China's miracle – and why this matters for the future Why China is on course towards a sudden eruption of political chaosAs always, we finish with my guest's reflections on humanity.

China's rise has shook the world. It has changed the lives of over a billion people in China. It has flooded humanity with cheap goods, from single-use toys to high-tech solar panels. And it has changed the logic of war and peace in the 21st Century.
But how to explain China's dramatic rise? Was it due to the wisdom of China's leaders after Mao? Or was it all about foreign investors searching for cheap labor?
Both and neither, argues MIT professor Yasheng Huang. Yes, the Chinese leaders learned from the mistakes of Mao. And yes, foreign money made a difference.
But there is a hidden story behind China’s rise - a story which merits our attention. This is a story with deep roots in history, but with the main act being played in the Chinese countryside during 1980’s. It is also a drama whose characters have never recovered from the tragedy that took place on the streets around Tiananmen Square during a warm summer night in 1989.
This is part 2 of this 3-part mini-series "What About China", hosted by me, Ilari Mäkelä, together with ChinaTalk’s Jordan Schneider. Part 1 looked at China's deep history. Part 3 will look at China's present and future.
In this part 2, we sketch the story of China's rise, meeting many colorful characters and discussing fascinating themes, such as:
How did Mao shape the direction of Chinese history? Why did China become richer than India? Why was 80's a golden era for liberal Chinese? How did the 1989 crackdown at Tiananmen square paved the way for China today?MENTIONS

The West has ruled history — at least the way history has been written. This is a shame. To tell the story of humans, we must tell the story of us all.
So what about the rest? What themes and quirks does their history hide? And what forces, if anything, prevented them of matching Europe’s rise?
I aim to cover these topics for several countries and cultures over the next year. But I wanted to start with China. To do so, I’ve teamed up with Jordan Schneider, the host of ChinaTalk.
Our guest is MIT professor Yasheng Huang (黄亚生). Huang is the author of Rise and Fall of the EAST – one of my all-time favorite books on China’s past and present.
In this episode, we explore the deep currents shaping China’s history.
We trace the forces shaping China's early mastery of technology to its falling behind Europe in the modern era. We also discuss the surprising role that standardized exams have played in Chinese history, and why certain democratic elements in China’s past actually bolstered the emperor’s authority.
The episode covers all of Chinese imperial history, ending with a brief note on the early 20th Century. In part 2, will zoom into China’s economic miracle and its uncertain future.

How do hunter-gatherers live? Do they wage war? Are they egalitarian? Do they really work for less?
These are fascinating questions. I’ve tried my best at covering them on the show. (You can see a list of episodes below).
But since 2023, the most controversial question has been on the role of women. Is it true that men hunt and women gather? Or is this theory, nicknamed “Man the Hunter”, a myth that should be buried for good?
I've covered this sensitive topic on the podcast and in writing. And for a moment, I thought I had it all figured out.
In late 2023, I concluded that there is no real debate, just an important reminder not to slip "from more to all". Yes, women hunt. No, they don't do it as much as men. And yes, this pattern is accepted by all serious scholars.
I was wrong.
Many scholars messaged me insisting that the debate was very real. Soon, new papers came out attacking the many headline grabbing claims of 2023.
I’ve spent a lot time in 2024 trying to get to the bottom of the topic. I’ve had conversations with several scholars on the matter.
The most interesting conversation I had with Katie Starkweather, an Assistant Professor of Anthropology at University of Illinois.
Starkweather studies women’s decision making in a variety of cultures. For years, she has been a thoughtful critic of many myths around women’s behaviour and biology. Typically, she pushed against traditionalist ideas about fixed gender roles. But she has also become a critic of the recent enthusiasm around “Woman the Hunter”. This makes her a particularly nuanced commentators on this sensitive topic.
We began this conversation by talking about the basic question: What's the current debate about? And what does should make of the evidence? (You can read my conclusion, with many more references, at OnHumans.Substack.com)
This was all interesting.
But towards the end, we also touch upon a deeper question: Does it matter? What is at stake in this debate? What are the implications for science? What about for gender equality? And what would a chimpanzee say about the topic?
As always, we finish with my guests reflection on humanity.

Agriculture changed everything. Traditionally, this “Neolithic Revolution” was celebrated for opening the gates of civilisation. Recently, it has been compared to the original sin. But whatever our take on agriculture, we should be puzzled by one thing: Why did our ancestors start to farm in the first place?
It's not like early farmers had improved lives. Quite the opposite, they worked harder and suffered from worse health. So why did so early farmers stick to it? And why did farming spread so far and wide?
Andrea Matranga thinks he has the answer.
An economic historian at the University of Torino, Matranga links agriculture to climate change. This is not a new idea — not as such. After all, agriculture developed in lockstep with the end of Ice Ages. For years, this vague link has formed my own pet-theory on the matter.
But I never paused to reflect on the obvious problem with it. There was never an “Ice Age” in Sudan. Why didn’t humans just farm there?
Matranga has the answer to this and many other puzzles. And surprisingly, his answer is linked to the movements of Jupiter. I will let him tell you why.
We begin this episode covering some previous theories on the origins of agriculture. Next, we dissect Matranga's theory and the evidence for it. Towards the end, we talk about the spread of farming — peaceful and violent — and note a neglected downside to the hunter-gatherer lifestyle. As always, we finish with my guest’s reflection on humanity.

You are driving a car. The brakes stop working. To your horror, you are approaching a busy street market. Many people might be killed if you run into them. The only way to prevent a catastrophe is by turning fast to the right. Unfortunately, a lonely pedestrian might be killed if you do so.
Should you turn? Many people say you should. After all, killing one is better than killing many. But following the same logic, would you kill an individual to collect their organs for people in dire need of one? In this case, too, you would kill one to save many. Yet very few are willing to do so.
Why?
These are variations of the infamous “trolley problems”. Originally formulated half a century ago, these trolley problems continue to elicit heated conversations. They have a whole meme culture built around them. Yet for years, I was not convinced of their value. They seemed to squeeze ethics into narrow funnels of “yeses" and "noes", neglecting much of real life's texture.
I have changed my mind. And I’ve done so largely thanks to Peter Railton.
A professor of philosophy at UC Michigan, Railton used to share my scepticism about the trolley problems. But he, too, changed his mind. Having in-depth conversations about them with his students, Railton came to see these problems as revealing some important about morality. Combined with recent evidence from psychology and neuroscience, Railton believes that these insights can reveal a lot about the human mind more generally.
I will let him tell you why.

The Industrial Revolution played in the hands of the rich. A century after James Watt revealed his steam engine in 1776, the richest 1% owned a whopping 70% of British wealth. Then things changed. Across rich countries, inequality plummeted for decades.
Join Branko Milanovic on this quest to understand the evolution of inequality during the building of modern prosperity. Our conversation ranges from Karl Marx to the "golden age” of American capitalism and from Yugoslavia’s market socialism to China's rise.

The Industrial Revolution did not create modern prosperity. Indeed, the British workers saw little or no improvements in their wages between 1750 and 1850. They did, however, experience ever-worsening working conditions.
Then things changed. Britain became a democracy. And with democracy, the economy changed, too.
Or so argues Daron Acemoglu, one of the most influential economists alive. You can either listen to the episode here, or read some highlights and commentary at Onhumans.Substack.com/

For millenia, patriarchy, population growth, and extractive elites made the world a bleak place for most humans. But there are good news, too: everything changed around 1870. And the changed happened due to the taming of the genius of people like Nikolai Tesla.

We live longer and grow taller than ever before. We are healthier and wealthier. Our ancestors could hardly have imagined a life of such prosperity. A future archaeologist would be equally puzzled. How did we become so rich so fast? What changes could have been so dramatic as to literally change the height of our species?
Our modern prosperity is not the outcome of slow and steady progress. For most of human history, there was no upward trend in the health and wealth of the average human. The big events of history rarely changed the life of the local farmer.
So what changed?
"The Birth of Modern Prosperity" is a four-part series exploring the recent revolution in the human condition. The series is composed of curated highlights from interviews with leading economic historians. Each episode introduces one leading theory about the origins of our modern experience. While doing so, they offer fresh answers to many old questions, such as: Is technological innovation a force for good? Did the Industrial Revolution benefit the masses? Is the world more or less equal than before?
The series will explore these topics from four angles:
Education, Family, & Colonialism (with Oded Galor) Inventors & Engineers (with Brad DeLong) Democracy & Labour (with Daron Acemoglu) Equality & Inequality (with Branko Milanovic)Today's episode is part 1 with Oded Galor, author ofThe Journey of Humanity: Origins of Wealth and Inequality. The original episodes are numbers 12 and 13.
We discuss:
The long arch of human history Why improvements in technology have rarely benefitted the masses Why this changed around the 1870s. The virtuous cycle of technology, education, and prosperityWe also compare the economic history of Britain and India to shed light on how colonialism has enforced age-old obstacles to prosperity.

Over half a century, Sarah Blaffer Hrdy has challenged many of our myths about parenting, attachment, and "human nature".
In this conversation, we dive into her remarkable career, culminating in her new book, Father Time.
[You can now order Father Time via Amazon or Princeton Uni Press]
We discuss a variety of topics, from hunter-gatherer parenting to the limitations of comparing humans to chimpanzees. We also discuss "allomothers", attachment theory, and the tragedy of infanticide. We finish with a discussion on the remarkable social changes in fatherhood and the neuroscience that has enabled it.
As always, we finish with Hrdy’s reflections on humanity.

Modern cities are unique. Never before have so many people lived so close to each other. But just how unique is our modern cosmopolitanism?
Completely unique, says a traditional theory.
Humans evolved in tiny groups. These groups were not only smaller than modern cities. They were smaller than medieval towns. Indeed, hunter-gatherers often move in bands of 25 people or so. These bands might draw people from a "meta-group" of 150 people — but not more. And so, 150 people is the "maxiimum" group size natural for humans. Or so the theory goes.
My guest today thinks that this is wrong.
Cecilia Padilla-Iglesias is an evolutionary ecologist who studies hunter-gatherer societies. And her work points to a very different conclusion. Yes, hunter-gatherers spend much of their time in small bands. But these bands can form much larger groups of connections, extending further and further away, even to areas with different languages. Even in the rainforest, cosmopolitanism is the norm.
So what do hunter-gatherer societies look like? And are they really good models of our deep past? We discuss these and other topics in this episode, touching upon topics such as:
(04:00) Living with hunter-gatherers
(10:30) Fluid societies

(17:20) Dawkins’ mistake

(43:40) Was agriculture a mistake?
As always, we end with my guest's reflections on humanity.

Infinity is a puzzling idea. Even young children ponder its various manifestations: What is the biggest number? Does the universe have an edge? Does time have a beginning?
Philosophers have tried to answer these questions since time immemorial. More recently, they have been joined by scientists and mathematicians.
So what have we learned? Can we finally understand infinity? And what has this quest taught us about ourselves?
To explore this topic, I am joined by philosopher Adrian W. Moore.
Professor Moore is a special guest for two reasons. First, he is a world expert on infinity, known for an excellent BBC series, "History of the Infinite". More personally, he is the head tutor of Philosophy at St Hugh’s College, Oxford, where I studied my BA in Philosophy and Psychology. It has now been ten years since Prof Moore interviewed me and, for whatever reason, accepted me as a student. I feel honoured to mark the occasion with this episode.
In this episode, we discuss:
(02:35) Why infinity fascinates
(12:20) Greeks on infinity
(20:05) A finite cosmos?
(25:00) Zeno’s paradoxes
(32:35) Answering Zeno
(42:35) Measuring infinities? Georg Cantor
(54:05) Infinity vs human understanding
(66:20) Mystics on infinity
As always, we finish with Prof Moore’s reflections on humanity.

Why are we furless? Why do we cook our food and use spoken language? And how does climate change, sashimi, or the banks of Central America relate to human origins?
Human evolution is a deeply puzzling topic. But behind this dense mist lies many keys to our self-understanding. To guide us through the foggy territory, I am joined by Dr Ian Tattersall, a curator emeritus at the American Museum of Natural History (New York).
In this episode, Dr Tattersall and I discuss:
(04.00) An ancient climate change
(07:20) First humans
(11:20) Fire
(17:50) Fish
(21:40) Rocks
(24:00) Evolution vs Innovation
(25:30) Brain growth
(36:10) Children
(39:50) Language
(48:20) Why?
As always, we finish with Dr Tattersall's reflections on humanity.

A note on hominin taxonomy: Homo habilis was traditionally considered the first human and the first maker of stone tools. Dr Tattersall is among the many critics of this old idea. According to him and many others, there is no separate tool-making species called Homo habilis. Rather, Australopithecines started making stone tools without any change in the biology of the species. Also, it is worth noting that Dr Tattersall rejects the traditional view which gives a big role for Homo erectus in the human story. In this traditional view, Turkana Boy’s species, Homo ergaster, is called an African Homo erectus. Dr Tattersall and many others argue that this is a historic hangover with little basis in the biological evidence.

We are conscious creatures. But why? Why did consciousness evolve? Can we use biology to explain the origins of feeling and meaning? Or will consciousness forever escape the grip of the scientific method?
Eva Jablonka has thought hard about these issues. An eminent evolutionary biologist, she became famous for her pioneering work on epigenetic inheritance. More recently, she has produced very original work on the evolution of consciousness with her colleague, neuroscientist Simona Ginsburg. So invited him on the show to discuss the evolution of consciousness, or what she beautifully calls "the sensitive soul".
In this episode, we discuss themes such as:
(03:00) What is consciousness?
(10:45) Four links between evolution and consciousness
(27:30) Are robots conscious? Consciousness and vulnerability
(30:45) Which animals are conscious? Consciousness and the Cambrian Explosion.
(34:30) Can science fully explain consciousness?
(48:00) The future of consciousness
As always, we end with Jablonka’s reflections on humanity.

Why do we love? What brings us together? How to heal ethnic hatred?
According to my guest, the answer to all these questions lies in the human desire to grow ourselves through connecting with others.
Arthur Aron is a psychologist who studies human bonding in all its forms. A pioneer in the field, he has studied topics from connecting with strangers to maintaining romance in life-long marriages. And many of his findings are ultimately hopeful.
In this conversation, we discuss topics such as:
(4:30) Why we love
(12:50) Tools to cultivate love
(24:30) Friendships with the ethnic "other”
(31:30) Are we naturally xenophobic?
