What are the facts? They are these:

With very great courtesy, one is impelled to ask those who argue that human nature in all its manifestations must remain unchanged how they interpret history. We have seen man progress from the mere animal fighting with other animals, seizing his food by force, seizing also by force his females, eating his own kind, the sons of the family struggling with the father for the possession of the father's wives; we have seen this incoherent welter of animal struggle at least partly abandoned for settled industry, and partly surviving as a more organized tribal warfare or a more ordered pillaging, like that of the Vikings and the Huns; we have seen even these pillagers abandon in part their pillaging for ordered industry, and in part for the more ceremonial
