“To me, the black black woman is our essential mother—the blacker she is the more us she is—and to see the hatred that is turned on her is enough to make me despair, almost entirely, of our future as a people.”
—Alice Walker (b. 1944)
“God gave the righteous man a certificate entitling him to food and raiment, but the unrighteous man found a facsimile of the same in God’s coffers, and appropriated it, and obtained food and raiment like the former. It is one of the most extensive systems of counterfeiting that the world has seen.”
—Henry David Thoreau (1817–1862)
