It is difficult to class them, some are too young, some are slow, some perverse.

—Ralph Waldo Emerson (1803–1882)
“Some rough political choices lie ahead. Should affirmative action be retained? Should preference be given to people on the basis of income rather than race? Should the system be—and can it be—scrapped altogether?”
—David K. Shipler (b. 1942)
