" Humans have this remarkable ability to know and not to know at the same time. Or more correctly, they can know something when they really think about it, but most of the time they don’t think about it, so they don’t know it. If you really focus, you realise that money is fiction. But usually you don’t focus. If you are asked about it, you know that football is a human invention. But in the heat of the match, nobody asks you about it. If you devote the time and energy, you can discover that nations are elaborate yarns. But in the midst of a war you don’t have the time and energy. If you demand the ultimate truth, you realise that the story of Adam and Eve is a myth. But how often do you demand the ultimate truth?
