I've argued that many of what philosophers call moral sentiments can be seen in other species. In chimpanzees and other animals, you see examples of sympathy, empathy, reciprocity, a willingness to follow social rules. Dogs are a good example of a species that have and obey social rules; that's why we like them so much, even though they're large carnivores.
Frans De WaalTo endow animals with human emotions has long been a scientific taboo. But if we do not, we risk missing something fundamental, about both animals and us.
