The Metaphysical Irreversibility of Death

The popularization of the term "clinical death" for the absence of vital signs suggests the possibility of a radical change in our understanding of death. While death used to be considered something that we do not have the power to reverse, contemporary optimism suggests that we may be able to restore life to a dead organism. In this article, I examine how the term "death" is used today to clarify what kind of irreversibility we ought to assign to it. I conclude that the kind of irreversibility closest to our concept of death is one that depends on implicit metaphysical commitments: we generally treat death as though it were metaphysically irreversible, and therefore not reversible by us.
