Think of a
murmuration of starling birds preparing to roost, and a
shot of Manhattan. Both are stunning images, and they are both the result of what's known in complex systems theory as self-organising
structures, where each individual is contributing to the whole in looking after
its own interests. The starlings are using basic rules determining how each
individual of the flock responds to its neighbours. The most notable thing is that one doesn’t
need any governing central planning principle to underpin the system – all
that’s needed is the procedures for each bird to look after itself, and those
beautiful flight patterns emerge in collective form.
The starling murmuration tells
us plenty about how we went from primitive hunter gatherers to citizens of places like Manhattan in just a few millennia,
and how once the wheels of industry were in motion the acceleration of our
progress exponentiated. The primary driving force of this has been trade, and
the value created (signalled by prices and behaviour) in a supply and demand
market
Think back to what the
first transactions might have looked like. Once upon a time, a hunter-gatherer
trades a piece of meat for some fur. The trade is beneficial to both parties because
each gets something they value more than the thing they parted with. Nowadays,
in this far more sophisticated age, each day involves millions of transactions,
where value is created because for the buyers the price they pay is valued less
than the item they are purchasing, and for the sellers the income they receive is
valued more than the item they are selling.
This is the primary
process that has led to our being much more advanced and prosperous humans in such a
relatively short time: it is one of the most stupendous self-organising
mechanisms the world has ever seen - so complex that it cannot possibly be
controlled from on high, yet so efficient that it has been the driving force
that has lifted tens of millions out of poverty, constructed things like the
city of Manhattan, engendered an interconnected world of travel and
information-sharing, brought us a rich variety of goods and services from a multitude
of diverse cultures, paid for health care, education, social services, defence,
armed forces, emergency services, medicine, science, the arts, roads, technological
advances, and countless other illuminations on the vast circuit board of human
progression.
It's always worth bearing
that in mind when you have a downer on capitalism. The reality is, it almost
resembles a miracle how through the local activity of individuals looking after
their own local interests the wider results produce things as wonderful as
Manhattan, worldwide travel and the Internet.
The way that trade and competition
brings about self-interest for the good of humankind, where prices
near-perfectly match supply and demand and create so much value and advancement,
is one of the most uniquely beautiful things the human story has ever
witnessed. What's particularly remarkable about it is that there is almost
nothing else in the world quite so efficient - even biological evolution has no mechanism quite as spectacularly efficient as this.
