Where does our sense of right and wrong come from? We peer inside the brains of people contemplating moral dilemmas, watch chimps at a primate research center share blackberries, observe a playgroup of 3 year-olds fighting over toys, and tour the country's first penitentiary, Eastern State Prison. Also: the story of land grabbing, indentured servitude and slum lording in the fourth grade.
Then we'll move from inner chimp to outer. Dr. Frans de Waals lets us watch a chimp fight at the Yerkes National Primate Research Center
in Atlanta. And we'll turn our navel-gazing toward the furrier navels of the chimps to learn a little more about this thing called morality: where it comes from, its evolutionary benefit, and why you can't guilt-trip an ape.
