If you look at national economies today, for example, the American economy, the European economy, the Indians, the Chinese, we're all tied together. If one of them sinks, the rest are going to sink with them and if one floats, the rest are lifted up. I find that very interesting.
Frans de WaalReligion may have become a codification of morality, and it may fortify it, but it's not the origin of it.
Frans de WaalThere's actually a lot of evidence in primates and other animals that they return favors.
Frans de WaalI'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.
