Ethics Animals Paper
Yes I'm covering all three areas. haha I know. That's one of my points for this paper too.

Ethics Animals Paper
that's true. Animals do have cognition, but they don't have all aspects of it. They think more instinctively than planning for the future.

Ethics Animals Paper
Would this be a good introductory paragraph? For several years, there has been an on-going debate over animal rights, animal testing, and where animals fit into our society. Whether or not they have morals, or if it's ethical to test them for the benefit of our own species...

Animal Community Paper (Ethics)
ok. how about... while society does not view animals as having cognition, therefore placing them outside the moral community, they still do belong and are involved with the human community.

oh also, that i dont believe in animal rights, so much as I believe in animal wellfare. I'm curious, how are animals not part of the moral community, when they are a part of the human community and interact with us on a daily basis?

Intro to Ethics
Ok. Thank you. So far I'm at the fact that animals do not have any rights, but that they are protected under our laws against abuse and neglect. They should not be given any rights because even though they are sentient intelligent beings, they do not have the human thought...
