Dignity. Daniel Keyes uses the closing events to show what dignity costs or achieves, rather than simply stating it.
Science ethics. The ending gives science ethics a final shape, which is why readers often point to it when they explain what the book is really about.
Loneliness. Even in the last scenes, loneliness keeps shaping the choices the characters make.
