I'm not sure about this. I saw an interesting episode of the BBC series Horizon a while back in which Danny Wallace tried to answer this question. A couple of the philosophers he spoke to were very dismissive and didn't even bother to address the question properly, but I thought the part where he met a chimp and she asked him to play chasey with him was quite lovely.
When we talked about this subject at uni the conclusion I came to was that animals should be treated more or less like children, ie. looked after but not expected to take full responsibilty for their own actions because they just don't have the same intelligence that we do. Looked at in a historical context though that sounds a bit creepy since there was a time when women and people of particular races were regarded as things or as children rather than fully fledged thinking adults.
I would think a big stumbling block would be that it's hard to measure the intelligence of a creature who is very different from us since they don't see the world the same way we do (literally even, some have different senses from us).
So...yeah, I really don't have an answer, but I'll be interested to see what other people come up with.
I don't think that chimps should be treated like humans, they don't have the intelligence, or communication skills. That being said, I also believe that animals should have more rights than they do. Animals are living being and that should give them rights all their own. Unfortunately, the world currently does not work that way. Hopefully, as we move forward, we will become more forward thinking in this regard.
Interesting question. I don't think that chimps should be legally considered people per se. But I certainly think they should be given the respect they deserve as intelligent and feeling animals, and that this should be protected by law, if they call these 'chimpanzee rights' then so be it. To cage an animals such as a chimp is despicable given what we know about the way they function and behave.
No. Chimpanzees are animals. If we started giving them legal personhood, we would then have to consider, Orangutans, Gorillas and all other apes. Having said that, animals are still deserving of our respect and consideration.
