Ishmael and his student go on to discuss how, for the ancient herders among whom the tale originated, the Biblical story of Cain killing Abel symbolizes the Leaver being killed off and their lands taken so that it could be put under cultivation. These ancient herders realized that the Takers were acting as if they were gods themselves, with all the wisdom of what is good and evil and how to rule the world: agriculture is, in fact, an attempt to more greatly create and control life, a power that only gods can hold, not humans. To begin discerning the Leavers' story, Ishmael proposes to his student a hypothesis: the Takers' Agricultural Revolution was a revolution in trying to strenuously and destructively live "above" the laws of nature, against the Leavers' more ecologically peaceful story of living "by" the laws of nature.
