In the next part, Regan describes the process how the beliefs are produced. He asks a question, how to make the moral status of animals become understandable, as start. Then, through an example that one’s neighbour kicks his dog, he raises a theory that the duties of humans to regard animals are indirect ones. In order to illustrate this theory more clearly, he quotes a conception called contractarianism which, in the follow several paragraphs, has been proved is not strongly enough to protect animal rights. Because, according to this theory, it systematically denies the duties that humans have to those, including animals undoubtedly, who do not have a sense of justice. Animals will be protected only depend on the sentimental interests of humans. Needless to say, the author needs to look for another theory.
Utilitarianism, which is mentioned next, has two main principles: equality and utility. The much more significant point is the second one, which means that what we will do must be brought out the best balance between satisfaction and frustration, and the best results for majority, even an evil means with a good end. Obviously, any adequate moral theory will refuse to justify this assertation. Again, Regan discards utilitarianism as an unsuitable theory.
