Homo sapiens is a post-truth species, whose power depends on creating and believing fictions. Ever since the Stone Age, self-reinforcing myths have served to unite human collectives. Indeed, Homo sapiens conquered this planet thanks above all to the unique human ability to create and spread fictions. We are the only mammals that can cooperate with numerous strangers because only we can invent fictional stories, spread them around, and convince millions of others to believe in them. As long as everybody believes in the same fictions, we all obey the same laws and can thereby cooperate effectively.

In the last few centuries, liberal thought developed immense trust in the rational individual. It depicted individual humans as independent rational agents and has made these mythical creatures the basis of modern society. Democracy is founded on the idea that the voter knows best, free-market capitalism believes that the customer is always right, and liberal education teaches students to think for themselves. It is a mistake, however, to put so much trust in the rational individual.

Globalization has made people in one country utterly dependent on markets in other countries, but automation might unravel large parts of this global trade network with disastrous consequences for the weakest links. In the twentieth century, developing countries lacking natural resources made economic progress mainly by selling the cheap labor of their unskilled workers. Today millions of Bangladeshis make a living by producing shirts and selling them to customers in the United States, while people in Bangalore earn their keep in call centers dealing with the complaints of American customers.

For years I had lived under the impression that I was the master of my life, the CEO of my own personal brand. But a few hours of meditation were enough to show me that I had hardly any control over myself. I was not the CEO; I was barely the gatekeeper.

Individual humans know embarrassingly little about the world, and as history has progressed, they have come to know less and less. A hunter-gatherer in the Stone Age knew how to make her own clothes, how to start a fire, how to hunt rabbits, and how to escape lions. We think we know far more today, but as individuals, we actually know far less.
