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 initial organization of the brain does not depend that much on experience. Nature provides a first draft, which experience then revises.

Almost everything we do is automatic, yet we're not aware of that. We feel like there's a circle of light. We're like the drunk who lost his keys and is looking under the streetlight, and the cop says, "Where'd you lose your keys?" You say, "Back in the alley, but the light's so much better over here." The divided self refers to the fact that we are basically animals with animal brains. These animal brains run our lives. They're very good at it.
