I think I could turn and live with the animals, they are so placid and self contained; I stand and look at them long and long. They do not sweat and whine about their condition; They do not lie awake 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 his kind that lived thousands of years ago; Not one is responsible or unhappy over the whole earth.
Walt Whitman, Leaves of Grass
