"Always the weed returns; the cultured plant retreats before it. Racial purity, true aristocracy, devolve not from edict, nor from rote, but from the preservation of kinship with the elemental forces and purposes of life whose understanding is not further beyond the mind of a Native shepherd than beyond the cultured fumblings of a mortar-board intelligence."
