"I swear the earth shall surely be complete to him or
her who shall be complete,
The earth remains jagged and broken only to him
or her who remains jagged and broken.
I swear there is no greatness or power that does not
emulate those of the earth,
There can be no theory of any account unless it
corroborate the theory of the earth,
No politics, song, religion, behavior, or what not,
is of account, unless it compare with the
amplitude of the earth,
Unless it face the exactness, vitality, impartiality,
rectitude of the earth."
- Walt Whitman, from "A Song of the Rolling Earth" in Leaves of Grass, first published 1855.
