In 1968, thirteen men gathered at the Harvard Medical School to virtually undo 5,000 years of the study of death. In a three-month period, the Harvard committee (full name: the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death) hammered out a simple set of criteria that today allows doctors to declare a person dead in less time than it takes to get a decent eye exam. A good deal of medical language was used, but in the end the committee’s criteria switched the debate from biology to philosophy. Before many years went by, it became accepted by most of the medical establishment that death wasn’t defined by a heart that could not be restarted, or lungs that could not breathe. No, you were considered dead when you suffered a loss of personhood.
But before we see what substituting philosophy for science actually means to real patients, let’s look at the criteria the Harvard authors believed indicated that a patient had a “permanently nonfunctioning brain”:
• Unreceptivity and unresponsivity. “Even the most intensely painful stimuli evoke no vocal or other response, not even a groan, withdrawal of a limb or quickening of respiration,” by the committee’s standard.
• No movements or spontaneous breathing (being aided by a respirator does not count). Doctors must watch patients for at least one hour to make sure they make no spontaneous muscular movements or spontaneous respiration. To test the latter, physicians are to turn off the respirator for three minutes to see if the patient attempts to breathe on his own (the apnea test).
• No reflexes. To look for reflexes, doctors are to shine a light in the eyes to make sure the pupils are dilated. Muscles are tested. Ice water is poured in the ears.
