“The neurologist and psychologist Maurice Nicoll told how he had once asked his headmaster about a passage in the Bible, and after he had listened to the answer for some time, he realized that the man had no idea what he was talking about. What I admire about Nicoll is that he made this discovery when he was only ten. It took me another forty-five years before the penny dropped: very, very few people have any idea what they are talking about.”
