Invisible Man and Whitman.  What does the last sentence mean? MacGuffins in the novel.  Du Bois on the education of Black Men.  1943 riot in Harlem and the end if Invisible Man.  William Henry Johnson's "Moon Over Harlem." Moral of Invisible Man: don't use people.  Doing so turns them into the kind of people who use people. (Even the Invisible Man does: uses Sibyl for example.)
