I think I could turn and live awhile with the animals,
They are so placid and self-contained,
I stand and look at them sometimes half the day long.
They do not sweat and whine about their condition,
They do not lie in the dark and weep for their sins,
They do not make me sick discussing their duty to God,
Not one is dissatisfied, not one is demented with the mania of owning things,
Not one kneels to another nor to his kind that lived thousands of years ago,
Not one is respectable or unhappy over the whole earth.
Walt Whitman, from "Song of Myself"
