This is a book about questioning what others believe to be true, not accepting ideas just because famous people say they are right. I think knowledge is more like a wave than a switch. Only very rarely do we go from being totally wrong to totally right--as a light turns off and on. Instead, what we learned before allows us to move on to what we can see next. We can surf ahead, but there will always be another challenge, another crest, another setp. We must always keep thinking and asking new questions.
