The sci-fi novel that actually gave us the term: 'time machine'. The book's protagonist travels to the year A.D. 802, 701, only to find that the state of the human race has changed considerably. He discovers two distinct peoples; the Eloi, and, the Morlocks, and originally believes that they share a kind of 'Lord/Servant' relationship. However, he soon realises that it is more like that of 'Ranchers/Livestock'.
