What does “dead” mean?

Should death be defined in strictly biological terms — as the body’s failure to maintain integrated functioning of respiration, blood circulation, and neurological activity? Should death be declared on the basis of severe neurological injury even when biological functions remain intact? Or is it essentially a social construct that should be defined in different ways?

❝ These are among the wide-ranging questions explored in a new special report, “Defining Death: Organ Transplantation and the Fifty-Year Legacy of the Harvard Report on Brain Death,”…The special report is a collaboration between The Hastings Center and the Center for Bioethics at Harvard Medical School.

Sometimes, these days, I think of death and dying. Some of us must. The old ones. I think of Dylan Thomas. I must needs think of science. Most of me pretty worn; but, I may provide a jot of knowledge simply for what I have experienced and survived.
