Have you come over time to think that you know more now than you did when you were young, know less now than when young, know now there is so much more to know than you knew there was to know when young that it is moot whether you think you knew more then than now or less, or do you now know that you never knew anything at all and never will and only the bluster of youth persuaded you that you did or would?
Padgett Powell, The Interrogative Mood
knowledge, youth
