 What about organ donation that goes beyond what is currently permitted, such as the donation of the second kidney or donation of an organ necessary for life? Liberal democracies do not generally allow consent to be a defense to bodily harm at or well below the level of death (Price 2000), but should they? The answer turns in part on how far third parties—transplant teams in this case—may inflict harms on those who genuinely give autonomous consent or, to put it another way, the extent to which autonomous people can waive their rights of bodily integrity. But policy considerations are also relevant. Can one be sure that consent is genuine? Would some people be forced into consenting in a way that a screening process would fail to detect? If so, how much weight should be attached to cases where organs are taken without genuine consent? These questions arise for living donation in general, but the errors are worse in cases where severe harm or death is the certain consequence of donation. (The questions also arise in the debates about whether voluntary slavery or euthanasia should be permitted (Feinberg 1986)).
