Abstract
Legal systems in the Western world currently regard animals as property. This status implies that they are not subjects of rights. None of the recent legal measures aimed at protecting animals have conferred on them the legal status of person, which is arguably a necessary condition to benefit from the most fundamental individual rights. In this chapter, we argue that the type of control of animals that is based on property rights and domination is ethically unacceptable. We also argue that extending personhood and its corresponding rights to all sentient beings is the best way to ensure that they are not made to suffer unnecessarily and that they are protected from domination. While there may exist morally legitimate occurrences of human control over other animals, justice requires that we abolish all forms of their exploitation.
