Walt Whitman said this quote
“ Poets to ComePOETS 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! Arousefor you must justify meyou must answer.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. ”
