Yuval Noah Harari:
The best test to know whether an entity is real or fictional is the test of suffering. A nation cannot suffer, it cannot feel pain, it cannot feel fear, it has no consciousness. Even if it loses a war, the soldier suffers, the civilians suffer, but the nation cannot suffer. Similarly, a corporation cannot suffer, the pound sterling, when it loses its value, it doesn’t suffer. All these things, they’re fictions.
