The reversibility of death

Area of Science:

• Medical Ethics
• Philosophy of Medicine
• Neuroscience

Background:

• The definition of death has evolved, with medical advancements leading to new criteria.
• Revisionary medical definitions often focus on the irreversible loss of brain function.
• Previous critiques have centered on the 'locus' (brain) rather than the 'irreversibility' condition.

Purpose of the Study:

• To analyze and compare the ordinary concept of death with revisionary medical definitions.
• To critically evaluate the 'irreversibility condition' in current medical definitions of death.
• To explore the epistemological and ethical implications of the irreversibility condition.

Main Methods:

• Philosophical analysis of the concept of death.
• Comparison of ordinary language definitions with medical criteria.
• Argumentation regarding the ambiguity and consequences of the irreversibility condition.

Main Results:

• The irreversibility condition in medical definitions of death is found to be ambiguous.
• The condition has unacceptable epistemic and other consequences under plausible interpretations.
• Irreversibility is not an inherent component of the ordinary concept of death.

Conclusions:

• Current medical definitions of death illegitimately conflate a weak construal of 'irreversible' (certainty) with a strong construal (freedom from moral obligation).
• The focus on irreversible brain function requires re-evaluation due to conceptual and practical issues.
• A clearer, more philosophically sound definition of death is needed.
