"Biologists are allowed an even smaller piece of the action by Jesse Prinz, a philosopher at the University of North Carolina. He believes morality developed after human evolution was finished and that moral sentiments are shaped by culture, not genetics. â??It would be a fallacy to assume a single true morality could be identified by what we do instinctively, rather than by what we ought to do,â?? he said. â??One of the principles that might guide a single true morality might be recognition of equal dignity for all human beings, and that seems to be unprecedented in the animal world.â??
Dr. de Waal does not accept the philosophersâ?? view that biologists cannot step from â??isâ?? to â??ought.â?? â??Iâ??m not sure how realistic the distinction is,â?? he said. â??Animals do have â??oughts.â?? If a juvenile is in a fight, the mother must get up and defend her. Or in food sharing, animals do put pressure on each other, which is the first kind of â??oughtâ?? situation.â??"
Great, he's not sure how realistic the distinction it is....He's not sure. Stop acting like he closed the case on the topic. He's still not even sure if the chimp's 'ought' IS, or IS not, an 'is.' In short, he's not doing anything new. Chimps exhibit social behavior. I think we all knew that.
