Walt Whitman: Song of the Open Road, Part 10

Allons! the inducements shall be greater,
We will sail pathless and wild seas,
We will go where winds blow, waves dash, and the Yankee clipper
speeds by under full sail.

Allons! with power, liberty, the earth, the elements,
Health, defiance, gayety, self-esteem, curiosity;
Allons! from all formules!
From your formules, O bat-eyed and materialistic priests.

The stale cadaver blocks up the passage—the burial waits no longer.

Allons! yet take warning!
He traveling with me needs the best blood, thews, endurance,
None may come to the trial till he or she bring courage and health,
Come not here if you have already spent the best of yourself,
Only those may come who come in sweet and determin'd bodies,
No diseas'd person, no rum-drinker or venereal taint is permitted here.

(I and mine do not convince by arguments, similes, rhymes,
We convince by our presence.)
