Culture is knowing the best that has been thought and said in the world; in other words, culture means reading, not idle and casual reading, but reading that is controlled and directed by a definite purpose. Reading, so understood, is difficult, and contrary to an almost universal belief, those who can do it are very few. I have already remarked the fact that there is no more groundless assumption than that literacy carries with it the ability to read. At the age of seventy-nine Goethe said that those who make this assumption "do not know what time and trouble it costs to learn to read. I have been working at it for eighteen years, and I can't say yet that I am completely successful."
