This first section tells a story about the origins of our morality. The story is just a story, not history or science. The story is not, however, merely fiction. The aim is to embed elements of the essential structure of the story at the beginning of Genesis about the Garden of Eden in an account whose details are mostly drawn from contemporary (non-theological) anthropology. It is still a story or myth, telescoping what a scientific account would spread over hundreds of thousands of years. The story does not mention God, but the fifth section of the chapter suggests that a storyteller who did mention God would provide a satisfying addition from an explanatory point of view. We can see the story as one that an anthropologist might tell her children, or as a Kant-like translation of the biblical story “within the boundaries of mere reason.”
Once upon a time there lived in Central Africa a group of apes. They were different from the groups of apes who lived around them, and they recognized this difference. For one thing, they seemed to be able to think of themselves as a group, and to think of what helped them as a group and what harmed them as a group. They would regularly meet together, and they sometimes had a kind of experience together when they met that also separated them from the other apes. They had an experience of everything belonging together, not just their own group, but everything. And it all seemed to them good and beautiful. Their assemblies gave them great joy and also a sense of awe, and they came to organize their lives together around them. They were able at these times to forget what kept them apart from each other, and to rejoice in what kept them together. Because of their new kind of unity, they were able to invent new cooperative ways to find food, and find new places to live that could sustain their form of life.
There arose among them a symbol for this goodness and beauty they had discovered, and a symbol of how the enjoyment of it distinguished them from the other apes in the old lands. They found themselves refraining from a particular kind of fruit, and this restraint was connected with their distinctive new form of life. Eating this fruit had been typical of the old way, the way of their ancestors, and they now needed to separate off their new way, connected with their new capacities and their new assemblies. They came to think of the fruit as forbidden by their common life, even though there was no reason (other than the symbolic connection) for refraining.
One day, when food was scarce, the elders of the group saw other animals eating the forbidden fruit, and they felt weariness with the restriction and a desire to go back to the old ways. They decided to eat the fruit themselves. This was a decision different in principle from eating the fruit in the old life, even though it was a decision to eat the same food, because it was now a decision against the authority of the common standard for their lives that they had accepted.
When they had made this decision, they found consequences that were natural but unexpected. One was that they lost the joy in their assemblies together. They also found their sexual lives changed. Before, they had been so conscious of what held them together as a group that they had not needed to protect themselves from each other, though they protected themselves and each other against common enemies. Now, they found themselves hiding from each other or fighting each other. The power of their common life waned, and competition increased for what each controlled individually. That included their food, but also their own bodies. They started to hide their bodies from each other by covering them, and to feel a new emotion of shame when they were uncovered.
Finally, the fighting and the competition between them got so bad that they were not able any longer to trust each other in the way required for the cooperation in finding food that they had discovered in their new place. Without this cooperation their lives there became unsustainable, and they were forced to leave. However, they kept with them the memory of how it had been, and the aspiration to return to it. They became in this way divided, each internally in their hearts, between the desire to protect what belonged to the individual and the desire for the common good that had been shared between them.
