Famous quotes containing the word black:
“It’s perversion. Don’t you see what it is? It’s not natural. To go to great expense for something you want, that’s natural. To reach out to take it, that’s human, that’s natural. But to get your pleasure from not taking, from cheating yourself deliberately like my brother did today, from not getting, from not taking. Don’t you see what a black thing that is for a man to do? How it is to hate yourself?”
—Abraham Polonsky (b. 1910)
