Poets to come! orators, singers, musicians to come!
  Not to-day is to justify me and answer what I am for,
  But you, a new brood, native, athletic, continental, greater than
      before known,
  Arouse! for you must justify me.

  I myself but write one or two indicative words for the future,
  I but advance a moment only to wheel and hurry back in the darkness.

  I am a man who, sauntering along without fully stopping, turns a
      casual look upon you and then averts his face,
  Leaving it to you to prove and define it,
  Expecting the main things from you.
