The applied ethical issue of euthanasia, or mercy killing, concerns whether it is morally
permissible for a third party, such as a physician, to end the life of a terminally ill patient
who is in intense pain.
The euthanasia controversy is part of a larger issue concerning the right to die.
Staunch defenders of personal liberty argue that all of us are morally entitled to end our
lives when we see fit. Thus, according to these people, suicide is in principle morally
permissible. For health care workers, the issue of the right to die is most prominent when a
patient in their care (1) is terminally ill, (2) is in intense pain, and (3) voluntarily chooses
to end his life to escape prolonged suffering. In these cases, there are several theoretical
options open to the health care worker. First, the worker can ignore the patient’s request
and care can continue as usual. Second, the worker can discontinue providing
life-sustaining treatment to the patient, and thus allow him to die more quickly. This
option is called passive euthanasia since it brings on death through nonintervention. Third,
the health care worker can provide the patient with the means of taking his own life, such
as a lethal dose of a drug. This practice is called assisted suicide, since it is the patient, and
not technically the health care worker, who administers the drug. Finally, the health care
worker can take active measures to end the patient’s life, such as by directly administering
a lethal dose of a drug. This practice is called active euthanasia since the health care
worker’s action is the direct cause of the patient’s death. Active euthanasia is the most
controversial of the four options and is currently illegal in the United States. However,
several right to die organizations are lobbying for the laws against active euthanasia to
Two additional concepts are relevant to the discussion of euthanasia. First,
voluntary euthanasia refers to mercy killing that takes place with the explicit and voluntary
consent of the patient, either verbally or in a written document such as a living will.
Second, nonvoluntary euthanasia refers to the mercy killing of a patient who is
unconscious, comatose, or otherwise unable to explicitly make his intentions known. In
these cases it is often family members who make the request. It is important not to confuse
nonvoluntary mercy killing with involuntary mercy killing. The latter would be done
against the wishes of the patient and would clearly count as murder.
Like the moral issues surrounding suicide, the problem of euthanasia has a long
history of philosophical discussion. On the whole, ancient Greek thinkers seem to have
favored euthanasia, even though they opposed suicide. An exception is is Hippocrates
(460-370 BCE), the ancient Greek physician, who in his famous oath states that “I will not
prescribe a deadly drug to please someone, nor give advice that may cause his death.” The
entire oath is presented below, which places emphasis on the value of preserving life and
in putting the good of patients above the private interests of physicians. These two aspects
of the oath make it an important creed for many heath care workers today. In medieval
times, Christian, Jewish, and Muslim philosophers opposed active euthanasia, although the
Christian Church has always accepted passive euthanasia.
During the Renaissance, English humanist Thomas More (1478-1535) defended
Euthanasia in book Utopia (1516). More describes in idealic terms the function of
hospitals. Hospital workers watch after patients with tender care and do everything in their
power to cure ills. However, when a patient has a torturous and incurable illness, the
patient has the option to die, either through starvation or opium. In New Atlantis (1627),
British philosopher Francis Bacon (1561-1626) writes that physicians are “not only to
restore the health, but to mitigate pain and dolours; and not only when such mitigation
may conduce to recovery, but when it may serve to make a fair and easy passage.”
One of the most cited contemporarly discussions on the subject of euthanasia is
“Active and Passive Euthanasia” (1975) by University of Alabama philosophy professor
James Rachels. Rachels argues that there is no moral difference between actively killing a
patient and passively allowing the patient to die. Thus, it is less cruel for physicians to use
active procedures of mercy killing. Rachels argues that, from a strictly moral standpoint,
there is no difference between passive and active euthanasia. He begins by noting that the
AMA prohibits active euthanasia, yet allows passive euthanasia. He offers two arguments
for why physicians should place passive euthanasia in the same category as active
euthanasia. First, techniques of passive euthanasia prolong the suffering of the patient, for
it takes longer to passively allow the patient to die than it would if active measures were
taken. In the mean time, the patient is in unbearable pain. Since in either case the decision
has been made to bring on an early death, it is cruel to adopt the longer procedure.
Second, Rachels argues that the passive euthanasia distinction encourages physicians to
make life and death decisions on irrelevant grounds. For example, Down’s syndrome
infants often have correctable congenital defects; but decisions are made to forego
corrective surgery (and thus let the infant die) because the parents do not want a child
with Down’s syndrome. The active-passive euthanasia distinction merely encourages these
Rachels observes that people think that actively killing someone is morally worse
than passively letting someone die. However, they do not differ since both have the same
outcome: the death of the patient on humanitarian grounds. The difference between the
two is accentuated because we frequently hear of terrible cases of active killings, but not
of passive killings. Rachels anticipates two criticisms to his argument. First, it may be
objected that, with passive euthanasia techniques, the physician does not have to do
anything to bring on the patient’s death. Rachels replies that letting the patient die involves
performing an action by not performing other actions (similar to the act of insulting
someone by not shaking their hand). Second, it may be objected that Rachels’s point is
only of academic interest since, in point of fact, active euthanasia is illegal. Rachels replies
that physicians should nevertheless be aware that the law is forcing on them an
indefensible moral doctrine.
In “Active and Passive Euthanasia: An Impertinent Distinction?” (1977), Thomas
Sullivan argues that no intentional mercy killing (active or passive) is morally permissible.
However, extraordinary means of prolonging life may be discontinued even though the
patient’s death may be foreseen. Sullivan argues that Rachels’s example of the Down’s
syndrome infant is misleading, since most doctors would perform corrective surgery since
it would be clearly wrong to let the infant die. Further, most reflective people will agree
with Rachels that there is no moral distinction between killing someone and allowing
someone to die. According to Sullivan, Rachels’s biggest mistake is that he misunderstands
the position of the AMA. The AMA maintains that all intentional mercy killing is wrong,
either active or passive. Although extraordinary procedures for prolonging life may be
discontinued for terminally ill patients, these procedures are ones that are both
inconvenient and ineffective for the patient. If death occurs more quickly by discontinuing
extraordinary procedures, it is only a byproduct. In short, to aim at death (either actively
or passively) is always wrong, but it is not wrong to merely foresee death when
discontinuing extraordinary procedures.
In a rejoinder essay, “More Impertinent Distinctions and a Defense of Active
Euthanasia” (1978), Rachels responds to Sullivan’s charges. Rachels begins noting that
Catholic thinkers, such as Sullivan, typically oppose mercy killing. However, Sullivan
himself concedes that it is sometimes pointless to prolong the dying process. Rachels
focuses on two specific points made by Sullivan. First, Sullivan argues that it is important
for the physician to have the correct intention (insofar as it is immoral to aim at the death
of a patient, but not immoral to foresee his death). Rachels counters that the physician’s
intention is irrelevant to whether the act is right or wrong. For, suppose two physicians
perform identical acts of withholding treatment, with one physician aiming at the death of
the patient, and the other only foreseeing it. Since the acts are identical, one cannot be
judged right and the other wrong. Second, Sullivan argues that physicians are justified
only in withholding extraordinary procedures. However, Rachels argues, to determine
whether a given procedure is ordinary or extraordinary, we must first determine whether
the patient’s life should be prolonged.
Rachels continues by offering several arguments in favor of the moral permissibility
of active euthanasia. The first is an argument from mercy. He begins by describing a
classic case where a person named Jack is terminally ill and in unbearable pain. Jack’s
condition alone is a compelling reason for the permissibility of active mercy killing. A
more formal utilitarian version of this argument is that active euthanasia is morally
permissible since it produces the greatest happiness. Critics have traditionally attacked
utilitarianism for focusing too heavily on happiness, and not enough on other intrinsic
goods, such as justice and rights. Accordingly, Rachels offers a revised utilitarian version:
active euthanasia is permissible since it promotes the best interests of everyone (such as
Jack, Jack’s wife, and the hospital staff). Rachels also argues that the golden rule supports
active euthanasia insofar as we would want others to put us out of our misery if we were
in a situation like Jack’s. A more formal version of this argument is based on Kant’s
categorical imperative (“act only on that maxim by which you can at the same time will
that it should become a universal law”). The categorical imperative supports active
euthanasia since no one would willfully universalize a rule which condemns people to
unbearable pain before death. Rachels closes noting an irony: the golden rule supports
active euthanasia, yet the Catholic church has traditionally opposed it.
