“I've argued that many of what philosophers call moral sentiments can be seen in other species.”
"Confessions of a Lonely Atheist" by Natalie Angier, in The New York Times Magazine (14 January 2001) http://partners.nytimes.com/library/magazine/home/20010114mag-atheism.html
Context: 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.
