Humility before New Scientific Evidence: We No Longer Have Moral Certainty that "Brain Death" Is True Death.

In light of the current medical evidence, physicians and ethicists no longer have the moral certainty that Pope John Paul II deemed vital for vital organ transplantation. The current medical evidence suggests that some brain-dead patients do seem to exhibit signs of global integration. This article will analyze the interpretations of this evidence, both from ethicists for and against the neurological criteria. Even the strongest arguments in favor of the neurological criteria in light of the new evidence fail to prove that the patient with total brain failure (TBF) has died. Furthermore, the recent Jahi McMath case demonstrates a new and alarming reality that there is no way in practice to distinguish global ischemic penumbra from TBF. In the absence of the moral certainty required by Pope John Paul II, it is clear that the Catholic Church should immediately call for a halt on vital organ transplantation. SUMMARY: This article analyzes the current medical evidence about brain death and argues that we have lost the moral certainty that Pope John Paul II deemed necessary for vital organ transplantation.
