"Everything we know has its origin in questions. Questions, we might say, are the principal intellectual instruments available to human beings. Then how is it possible that no more than one in one hundred students has ever been exposed to an extended and systematic study of the art and science of question-asking? How come Alan Bloom did not mention this, or E. D. Hirsh, Jr., or so many others who have written books on how to improve our schools? Did they simply fail to notice that the principal intellectual instrument available to hu­man beings is not examined in school?"
