The United States themselves are essentially the greatest poem.

I bequeath myself to the dirt to grow from the grass I love
If you want me again look for me under your boot-soles.
You will hardly know who I am or what I mean
But I shall be good health to you nonetheless
And filter and fibre your blood.

The city sleeps and the country sleeps,
The living sleep for their time, the dead sleep for their time,
The old husband sleeps by his wife and the young husband sleeps by his wife;
And these tend inward to me, and I tend outward to them,
And such as it is to be of these more or less I am,
And of these one and all I weave the song of myself.

A writer can do nothing for men more necessary, satisfying, than just simply to reveal to them the infinite possibility of their own souls.
