Despite its familiarity and widespread acceptance, the concept of “brain death” remains incoherent in theory and confused in practice. Moreover, the only purpose served by the concept is to facilitate the procurement of transplantable organs. By abandoning the concept of brain death and adopting different criteria for organ procurement, we may be able to increase both the supply of transplantable organs and clarity in our understanding of death.

Some form of agent-relative constraint against the killing of innocent personsis a central principle in deontological moraltheories. In this article I make two claimsabout this constraint. First, I argue that somekillings of innocents performed incircumstances usually not taken to exculpatethe killer are not even pro tanto wrong.Second, I contend that either there is noagent-relative constraint against the killingof innocents or this constraint has a verydifferent shape from that which deontologistsnormally take it to have. My defence of theseclaims rests on two (...) propositions. First, inkilling someone one may actually prolong thatperson''s life. Roughly, life-prolongingkillings are possible, because to kill someoneis to perform an act that causes someone''sdeath and it might well be true that, had onenot performed this act, one''s ``victim'''' wouldhave died earlier. Second, all other thingsbeing equal, killing and causing a person to beunconscious are morally equivalent. Both ofthese propositions are defended in thearticle. (shrink)
