Animal Sentience
The basis of animal rights is the recognition that animals are sentient beings.
This means they are capable of being aware of sensations and emotions, of feeling pain and suffering, and of experiencing a state of well being. ARAs believe that our own behavior towards animals should be guided by this recognition of their sentience.
There are many types of animals. An earthworm is an animal, and it is undoubtedly not sentient. It has no brain, just a nerve ganglion, with negligible intelligence. A chimpanzee is also an animal, and they are estimated to have an intelligence comparable to that of a five year old human child, which clearly does fall within the range of sentience. So it depends which species we are talking about.
