Not all dissidents are imprisoned. Some write books at home or at the office or in libraries that give others an imagination for a new way of life— the way Harriet Beecher Stowe did in Uncle Tom’s Cabin, the way Alan Paton did in Cry, the Beloved Country, the way Dee Brown did in Bury My Heart at Wounded Knee, and the way Ralph Ellison did in The Invisible Man . . . some make Marvel movies . . . . . . and you may add others to the list.
