People have always told tales. Long before humanity learned to write and gradually became literate, everybody told tales to everybody else and everybody listened to everybody else's tales. Before long it became clear that some of the still illiterate storytellers told more and better tales than others, that is, they could make more people believe their lies.
Lies that do not hurt, which are different from lies that protect oneself or hurt another person. That is not my business. But the truth is mostly very boring, and you can help it along with lies. There is no harm in that.
Believing: it means believing in our own lies. And I can say that I am grateful that I got this lesson very early.
