Ever since the Cognitive Revolution, Sapiens have thus been living in a dual reality. On the one hand, the objective reality of rivers, trees and lions; and on the other hand, the imagined reality of gods, nations and corporations. As time went by, the imagined reality became ever more powerful, so that today the very survival of rivers, trees and lions depends on the grace of imagined entities such as the United States and Google.

The cause of war is fictional, but the suffering is 100 per cent real. This is exactly why we should strive to distinguish fiction from reality.

Can a nation really suffer? Has a nation eyes, hands, senses, affections and passions? If you prick it, can it bleed? Obviously not. If it is defeated in war, loses a province, or even forfeits its independence, still it cannot experience pain, sadness or any other kind of misery, for it has no body, no mind, and no feelings whatsoever. In truth, it is just a metaphor.

Fiction isn't bad. It is vital. Without commonly accepted stories about things like money, states or corporations, no complex human society can function. We can't play football unless everyone believes in the same made-up rules, and we can't enjoy the benefits of markets and courts without similar make-believe stories. But the stories are just tools. They should not become our goals or yardsticks. When we forget that they are mere fiction, we lose touch with reality.
