I know that isn't the most exciting title but bear with me.
There are many ways to describe the twentieth century but one that brings together how we did business, ran politics and thought about life seemed to be systems theory.
From the way that factories built things to how we constructed our welfare system, the general principle was built on theories that stemmed from management experts.
These theories were developed to address how to manage large workforces, get the most out of the production process and deal with employees.
Of course, it wasn't just systems theory. There were political ideas too but they appeared to reflect or find inspiration from the idea that there was a rational system for everything as long as you found the right process or procedure.
The combination of European rationalism, which began a century before by Rousseau and made flesh by Robespierre, with systems theory proved to be, at its worst, deathly and at its best stifling.
It's grip on how we think is strong. It tells us that we can design models to predict behaviour and to some extent events. It tells us that we can identify our sub-conscious impulses and eradicate them and it tells us that if we don't conform to certain definitions of humanity, we cannot possibly be human.
Management theory and rationalism still hold sway but there is evidence that we are seeing a shift.
John Kay's book
Obliquity looks at the flaws of thinking that you know everything.
These ideas are not new.
Over half a century ago,
Hayek wrote about spontaneous order.
He was in favour of people running their lives and organising themselves as they wished.
This approach is very different from the belief that you can use management or systems theory to order society.
If the twentieth century was the century of process and systems, perhaps this century will be one of spontaneous order?
After all, we now have a technological infrastructure that allows us to organise how we do things without a central planning unit to direct our efforts.
But the final bit of the jigsaw would be to embrace Hayek's rejection of macro thinking.
