In this paper, I introduce the ideas to be discussed in the articles of this journal with reference to an imaginary case involving a pregnant woman declared dead on the basis of neurological criteria. I highlight the fact that although these ideas have proved useful for advancing certain claims in bioethical debates, their implications are not always well understood and may complicate our arguments. The ideas to be discussed are an ethic internal to the profession of medicine; the difference between (...) killing and letting die; the organism as a whole; and the “lives” and interests of the dead.
