“The sight of a Black nun strikes their sentimentality; and, as I am unalterably rooted in native ground, they consider me a work of primitive art, housed in a magical color; the incarnation of civilized, anti-heathenism, and the fruit of a triumphing idea.”
—Alice Walker (b. 1944)
“Greed is a bottomless pit which exhausts the person in an endless effort to satisfy the need without ever reaching satisfaction.”
