This article discusses the status of animal rights, and more particularly whether these rights may be defended from a natural rights perspective or from an ethical perspective. I argue that both options fail. The same analysis applies in the case of humanity. 'Humanity' does not bring with it the acknowledgement of such rights, nor does a focus on what is arguably characteristic of humanity, namely, reason. Reason is decisive, though, in another respect, namely, the fact that reasonable beings can claim and lay down rights. It does not follow from this that animals should have no rights, since human beings may be motivated to constitute such rights, thus providing the most solid basis for them.
