In practice, people choose the book considered sacred by the community in which they are born, and out of that book they choose the parts they like, ignoring the others. At one time, the most influential text in the Bible was: “Thou shalt not suffer a witch to live.” Nowadays, people pass over this text, in silence if possible; if not, with an apology. And so, even when we have a sacred book, we still choose truth whatever suits our own prejudices.
