Urbanisation
The City That Taught Us What Cities Are For
For most of human history, the city wasn't a place people chose — it was a place that chose them.
The Idea
We tend to think of urbanisation as a modern phenomenon, a consequence of industrialisation and economic migration. But the pull of cities is far older and stranger than that story suggests. The first cities — emerging in Mesopotamia around 3500 BCE, in the Indus Valley, in early China — weren't just settlements that grew large. They were fundamentally new kinds of social technology: machines for concentrating strangers and forcing cooperation between them. What makes a city a city isn't population density. It's the density of non-kin relationships — connections between people who share no blood, tribe, or village history. This is what the sociologist Georg Simmel noticed in 1903, writing about the mental life of the metropolis: the city produces a particular psychological type, someone who has learned to be selectively indifferent in order to stay sane amid the crush of strangers. The 'blasé attitude' he described wasn't rudeness — it was a cognitive adaptation. This is the underappreciated tension at the heart of urbanisation: cities simultaneously produce more creativity, more disease, more crime, more art, more inequality, and more innovation than any other human arrangement. They are amplifiers. Whatever human beings are capable of — beautiful and terrible — cities turn up the volume. The question urbanisation really poses isn't 'why do people move to cities?' It's 'what do we become when we do?'
In the World
Çatalhöyük, in what is now central Turkey, gives us one of the most disorienting windows into early urban life. Occupied from roughly 7500 to 5700 BCE, it housed up to 8,000 people at its peak — a genuinely dense settlement for the Neolithic world. Archaeologists excavating it through the twentieth century expected to find the usual markers of urban hierarchy: palaces, temples, a ruling class with bigger houses. They found almost none of that. The houses at Çatalhöyük were strikingly uniform in size. There were no streets — people entered their homes through holes in the roof and moved across the settlement by walking over other people's houses. The dead were buried beneath the floors of the living. Skulls were sometimes retrieved, plastered, and kept. The walls were covered in paintings of vultures and headless humans that still resist confident interpretation. What Çatalhöyük reveals is that urban density doesn't automatically produce the social hierarchies we associate with cities. For centuries, thousands of people lived cheek-by-jowl without obvious kings or priests accumulating disproportionate power. The city wasn't yet an engine of stratification — it was something stranger and more experimental than that. It took millennia of urbanisation before the template we now take for granted — the powerful centre, the peripheral poor, the anonymity of the crowd — became cities' default mode.
Why It Matters
Most of us now live in cities, or are shaped by cities even if we don't. It's easy to experience urban life as a given — the traffic, the noise, the cost, the loneliness in crowds — without recognising it as a historically peculiar way of being human that we are still, in some sense, adapting to. Simmel's insight about the blasé attitude is genuinely useful here. When city life feels alienating, it's worth asking whether what you're experiencing is failure — or a feature. The psychological distance urbanisation demands of us is real, and it costs something. But it also produces something: the possibility of encounters with people radically unlike you, the creative friction of proximity, the anonymity that lets you reinvent yourself. Understanding urbanisation as a social technology — one that was invented, iterated on, and is still being redesigned — means you can hold cities more lightly. Not as the natural endpoint of human civilisation, and not as a problem to be solved, but as an ongoing experiment in what it means to live among strangers. The experiment is still running.
A Question to Ponder
In your own daily urban life, where do you notice Simmel's blasé attitude in yourself — and is it protecting you, or costing you something worth keeping?
