Jarvis is going through the things in Arthur's study. Arthur's bookshelves are filled with biographies of Abraham Lincoln and books on South Africa and race.
His desk is covered with pages of Arthur's writing on South African politics. Apparently, Arthur believes that the white people who live in South Africa now have a responsibility to invest in education and social institutions for black South Africans, since the white people have destroyed the traditional black tribal cultures that used to function there.
As he walks out the door of Arthur's house, Jarvis thinks of what his son looked like as a small boy. (Sniff. Sorry, excuse us, just—where's that Kleenex?)
