The various features of bioethics center around a person’s right to decide what happens to her body and what she may do with it. This is true for patients and medical professionals. Our intuitions concerning rights in bioethics are similar to our intuitions concerning rights in other areas. Consider, for example, rights concerning movement, privacy, religion, sex, speech, and thought. Intuitively, these rights are consistent with one another, trump other moral considerations, and can be lost. If people were to own themselves, this would provide a unified explanation of what justifies other rights, what particular rights people have, why these particular rights are consistent with one another, and why these particular rights have certain features, such as trumping utility. Here I explore whether people own themselves.
