Nicholas Wade in today's NYT: "... primatologists have shown... a sizable overlap between the behavior of people and other social primates..."
"Though human morality may end in notions of rights and justice and fine ethical distinctions, it begins, Dr. de Waal says, in concern for others and the understanding of social rules as to how they should be treated. At this lower level, primatologists have shown, there is what they consider to be a sizable overlap between the behavior of people and other social primates.
Social living requires empathy, which is especially evident in chimpanzees, as well as ways of bringing internal hostilities to an end. Every species of ape and monkey has its own protocol for reconciliation after fights, Dr. de Waal has found. If two males fail to make up, female chimpanzees will often bring the rivals together, as if sensing that discord makes their community worse off and more vulnerable to attack by neighbors. Or they will head off a fight by taking stones out of the males’ hands.
Dr. de Waal believes that these actions are undertaken for the greater good of the community, as distinct from person-to-person relationships, and are a significant precursor of morality in human societies...
Dr. de Waal’s definition of morality is more down to earth than Dr. Prinz’s. Morality, he writes, is “a sense of right and wrong that is born out of groupwide systems of conflict management based on shared values.” The building blocks of morality are not nice or good behaviors but rather mental and social capacities for constructing societies “in which shared values constrain individual behavior through a system of approval and disapproval.” ...
“Morality is as firmly grounded in neurobiology as anything else we do or are,” Dr. de Waal wrote in his 1996 book “Good Natured.” Biologists ignored this possibility for many years, believing that because natural selection was cruel and pitiless it could only produce people with the same qualities. But this is a fallacy, in Dr. de Waal’s view. Natural selection favors organisms that survive and reproduce, by whatever means. And it has provided people, he writes in “Primates and Philosophers,” with “a compass for life’s choices that takes the interests of the entire community into account, which is the essence of human morality.”
