We are by far the most contradictory of all primates. An animal with this much internal conflict has never lived on this earth.
Frans de WaalI am personally not against keeping animals at zoos, as they serve a huge educational purpose, but treating them well and with respect seems the least we could do, and with 'we' I mean not just zoo staff, but most certainly also the public.
Frans de WaalIt is not only visitors to the zoo who are fascinated but uneasy in the presence of chimpanzees; the same is true of scientists. The more they learn about these great apes, the deeper our identity crisis seems to become. The resemblance between humans and chimpanzees is not only external. If we look straight and deep into a chimpanzeeโs eyes, an intelligent, self-assured personality looks back at us. If they are animals, what must we be?
