Love and work are to people what water and sunshine are to plants.
The rider evolved to serve to the elephant.
The most powerful force ever known on this planet is human cooperation - a force for construction and destruction.
Groups create supernatural beings not to explain the universe but to order their societies.
You can see the rider serving the elephant when people are morally dumbfounded. They have strong gut feelings about what is right and wrong, and they struggle to construct post hoc justifications for those feelings. Even when the servant (reasoning) comes back empty-handed, the master (intuition) doesn't change his judgment.
The mind is divided, like a rider on an elephant, and the rider's job is to serve the elephant.
