Lies, lies, lies. We all tell them even though we are told from an early age not to. In this very entertaining book, the author postulates that what made our brains so superior to other primates’ was our ability to invent and use our imagination, in other words to tell lies. He touches on a variety of subjects such as developmental psychology, theology, mesmerism, Benjamin Franklin, and the lie detector. I particularly enjoyed the part about « mental reservation » by which Catholics were allowed to omit certain truths by adding words in their head. A delight!
