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.
