BRIEFING* (from BIOETHICS NEWS Vol.11 No. 4 July 1992 page 40)
Introduction
'Euthanasia' is a compound
of two Greek words - eu and thanatos meaning, literally, 'a good
death'. Today, 'euthanasia' is generally understood to mean the
bringing about of a good death - 'mercy killing,' where one person,
A, ends the life of another person, B, for the sake of B.
This understanding of euthanasia
emphasizes two important features of acts of euthanasia. First,
that euthanasia involves the deliberate taking of a person's life;
and, second, that life is taken for the sake of the person whose
life it is - typically because she or he is suffering from an incurable
or terminal disease. This distinguishes euthanasia from most other
forms of taking life.
Every society known to us
subscribes to some principle or principles prohibiting the taking
of life. But there are great variations between cultural traditions
as to when the taking of life is considered wrong. If we turn to
the roots of our Western tradition, we find that in Greek and Roman
times such practices as infanticide, suicide and euthanasia were
widely accepted. Most historians of Western morals agree that Judaism
and the rise of Christianity contributed greatly to the general
feeling that human life has sanctity and must not deliberately be
taken. To take an innocent human life is, in these traditions, to
usurp the right of God to give and take life. It has also been seen
by influential Christian writers as a violation of natural law.
This view of the absolute
inviolability of innocent human life remained virtually unchallenged
until the sixteenth century when Sir Thomas More published his Utopia.
In this book, More portrays euthanasia for the desperately ill as
one of the important institutions of an imaginary ideal community.
In subsequent centuries, British philosophers (notably David Hume,
Jeremy Bentham and John Stuart Mill) challenged the religious basis
of morality and the absolute prohibition of suicide, euthanasia
and infanticide. The great eighteenth-century German philosopher
Immanuel Kant, on the other hand, whilst believing that moral truths
were founded on reason rather than religion, nonetheless thought
that 'man cannot have, the power to dispose of his life' (Kant,
1986, p.148).
Mercy for a hopelessly ill
and suffering patient and, in the case of voluntary euthanasia,
respect for autonomy, have been the primary reasons given by those
who have argued for the moral permissibility of euthanasia. Today,
there is widespread popular support for some forms of euthanasia
and many contemporary philosophers have argued that euthanasia is
morally defensible.
Official religious opposition
(for example, from the Roman Catholic Church) does, however, remain
unchanged, and active euthanasia remains a crime in every nation
other than the Netherlands. There, a series of court cases, beginning
in 1973, have established the conditions under which doctors, and
only doctors, may practise euthanasia: the decision to die must
be the voluntary and considered decision of an informed patient;
there must be physical or mental suffering which the sufferer finds
unbearable; there is no other reasonable (i.e. acceptable to the
patient) solution to improve the situation; the doctor must consult
another senior professional.
Before looking more closely
at the arguments for and against euthanasia, it will be necessary
to draw some distinctions. Euthanasia can take three forms: it can
be voluntary, non-voluntary and involuntary.
Voluntary, non-voluntary
and involuntary euthanasia
The following case is an
example of voluntary euthanasia: Mary F. was dying from a progressively
debilitating disease. She had reached the stage where she was almost
totally paralysed and, - periodically, needed a respirator to keep
her alive. She was suffering considerable distress. Knowing that
there was no hope and that things would get worse. Mary F. wanted
to die. She asked her doctor to give her a lethal injection to end
her life. After consultation with her family and members of the
health care team, Dr. fi. administered the asked-for lethal Injection,
and Mary F. died.
The case of Mary F. is a
clear case of voluntary euthanasia; that is, euthanasia carried
out by A at the request of B. There is a close connection between
voluntary euthanasia and assisted suicide, where one person will
assist another to end her life - for example, when A obtains the
drugs that will allow B to suicide. Euthanasia can be voluntary
even if the person is no longer competent to assert her wish to
die when her life is ended. You might wish to have your life ended
should you ever find yourself in a situation where, whilst suffering
from a distressing and incurable condition, illness or accident
have robbed you of all your rational faculties, and you are no longer
able to decide between life and death. If, whilst still competent,
you expressed the considered wish to die when in a situation such
as this, then the person who ends your life in the appropriate circumstances
acts upon your request and performs an act of voluntary euthanasia.
Euthanasia is non-voluntary
when the person whose life is ended cannot choose between life and
death for herself - for example, because she is a hopelessly ill
or handicapped newborn infant, or because illness or accident have
rendered a formerly competent person permanently incompetent, without
that person having previously indicated whether she would or would
not like euthanasia under certain circumstances.
Euthanasia is involuntary
when It is performed on a person who would have been able to give
or withhold consent to her own death, but has not given consent
- either because she was not asked, or because she was asked but
withheld consent, wanting to go on living. Whilst clear cases of
involuntary euthanasia would be relatively rare (for example, where
A shoots B without B's consent, to save her from falling into the
hands of a sadistic torturer), it has been argued that some widely-accepted
medical practices (such as the administration of increasingly large
doses of pain killing drugs that will eventually cause the patient's
death, or the unconsented-to withholding of life-sustaining treatment)
amount to involuntary euthanasia.
Active and Passive
Euthanasia
So far, we have defined 'euthanasia'
loosely as 'mercy-killing', where A brings about the death of B,
for the sake of B. There are, however, two different ways in which
A can bring B's death about: A can kill B by, say, administering
a lethal injection: or A can allow B to die by withholding or Withdrawing
life-sustaining treatment.
Cases of the first kind are
typically referred to as 'active' or 'positive' euthanasia,
whereas cases of the second kind are often referred to as 'passive'
or 'negative' euthanasia. All three kinds of euthanasia listed
previously - voluntary, non-voluntary and involuntary euthanasia
- can either be passive or active.
If we change the above case
of Mary F., but slightly, it becomes one of passive voluntary
euthanasia:
Mary F. was dying from a
progressively debilitating disease. She had reached the stage where
she was almost totally paralysed and periodically needed a respirator
to keep her alive. She was suffering considerable distress. Knowing
that there was no hope and that things would get worse, Mary F.
wanted to die. She asked her doctor to ensure that she would not
be put on a respirator when her breathing would fail next. The doctor
agreed with Mary's wishes, instructed the nursing staff accordingly,
and Mary died eight hours later, from respiratory failure.
There is a widespread agreement
that omissions as well as actions can constitute euthanasia. The
Roman Catholic Church, in its Declaration on Euthanasia, for example,
defines euthanasia as 'an action or omission which of itself or
by intention causes death' (1980, p.6.). Philosophical disagreement
does, however, arise over which actions and omissions amount to
euthanasia. Thus it is sometimes denied that a doctor practises
(non-voluntary passive) euthanasia when she refrains from resuscitating
a severely handicapped newborn infant, or that a doctor engages
in euthanasia of any kind when she administers increasingly large
doses of a painkilling drug that she knows will eventually result
in the patient's death. Other writers hold that whenever an agent
deliberately and knowingly engages in an action or an omission that
results in the patient's foreseen death, she has performed active
or passive euthanasia. In spite of the great diversity of views
on this matter, debates on euthanasia have time and again focused
on certain themes:
- Does it make a moral
difference whether death is actively (or positively) brought about,
rather than occurring because life-sustaining treatment is withheld
or withdrawn?
- Must all available life-sustaining
means always be used, or are there certain 'extraordinary' or
'disproportionate' means that need not be employed?
- Does it make a moral difference
whether the patient's death is directly intended, or whether it
comes about as a merely foreseen consequence of the agent's action
or omission?
The following is a brief
sketch of these debates.
Actions and Omissions
/ Killing and Letting Die
To shoot someone is an action:
to fail to help the victim of a shooting is an omission. If A shoots
B and B dies, A has killed B. If C does nothing to save B's life,
C lets B die.
But not all actions or omissions
that result In a person's death are of central interest in the euthanasia
debate. The euthanasia debate is concerned with intentional actions
and omissions, that is, with deaths that are deliberately and knowingly
brought about in a situation where the agent could have done otherwise
- that is, where A could have refrained from killing B, and where
C could have saved B's life.
There are some problems in
distinguishing between killing and letting die, or between active
and passive euthanasia. If the killing/letting die distinction were
to rest simply on the distinction between actions and omissions,
then the agent who, say, turns off the machine that sustains B's
life, kills B, whereas the agent who refrains from putting C onto
a life-sustaining machine in the first place, merely allows C to
die.
That killing and letting
die should be distinguished in this way has struck many writers
as implausible, and attempts have been made to draw the distinction
In some other way. One plausible suggestion is that we understand
killing as initiating a course of events that leads to death; and
allowing to die as not intervening in a course of events that leads
to death. According to this scheme, the administration of a lethal
Injection would be a case of killing; whereas not putting a patient
on a respirator, or taking her off, would be an instance of letting
die. In the first case, the patient dies because of events set in
train by the agent. In the second case, the patient dies because
the agent does not intervene in a course of events (e.g. a life-threatening
disease) already in train that is not of the agent's making.
Is the distinction between
killing and letting die, or between active and passive euthanasia,
morally significant? Is killing a person always morally worse than
letting a person die?
Various reasons have been
proposed why this should be so. One of the more plausible ones is
that an agent who kills causes death, whereas an agent who lets
die merely allows nature to take its course. This distinction between
'making happen' and 'letting happen', it has been argued, is a morally
important one insofar as it sets limits to an agent's duties and
responsibilities to save lives. Whilst it requires little or no
effort to refrain from killing anyone, it usually requires effort
to save a person. If killing and letting die were morally on a par,
so the argument goes, then we would be just as responsible for the
deaths of those whom we fail to save as we are for the deaths of
those whom we kill - and failing to aid starving Africans would
be the moral equivalent of sending them poisoned food. (See Foot,
1980, p.161-2.) This, the argument continues, is absurd: we are
more, or differently, responsible for the deaths of those whom we
kill than we are for the deaths of those whom we fail to save. Thus,
to kill a person is, other things being equal, worse than allowing
a person to die.
But even if a morally relevant
distinction can sometimes be drawn between killing and letting die,
this does not, of course, mean that such a distinction always prevails.
Sometimes at least we are as responsible for our omissions as we
are for our actions. A parent who does not feed her infant, or a
doctor who refrains from giving insulin to an otherwise healthy
diabetic, will not be absolved of moral responsibility by merely
pointing out that the person in her charge died as a consequence
of what she omitted to do.
Moreover, when the argument
about the moral significance of the killing/letting die distinction
is raised in the context of the euthanasia debate, an additional
factor needs to be considered. To kill someone, or deliberately
to let someone die, is generally a bad thing because it deprives
that person of her life. Under normal circumstances persons value
their lives, and to continue to live is in their best interest.
This is different when questions of euthanasia are at issue, In
cases of euthanasia, death - not continued life - is in the person's
best interest. This means that an agent who kills, or an agent who
lets die, is not harming but benefiting the person whose life it
is. This has led writers in the field to suggest: if we are, indeed,
more responsible for our actions than for our omissions, then A
who kills C In the context of euthanasia will, other things being
equal, be acting morally better than B who lets C die - for A positively
benefits C, whereas B merely allows benefits to befall C.
Ordinary and extraordinary
means
Powerful medical technologies
allow doctors to sustain the lives of many patients who, only a
decade or two ago, would have died because the means were not available
to avert death. With this an old question is raised with renewed
urgency: must doctors always do everything possible to try to save
a patient's life? Must they engage in 'heroic' efforts to add another
few weeks, days, or hours to the life of a terminally ill and suffering
cancer patient? Must active treatment always be instigated with
regard to babies born so defective that their short life will be
filled with little more than continuous suffering?
Most writers in the field
agree that there are times when life-sustaining treatment should
be withheld and a patient allowed to die. This view is shared even
by those who regard euthanasia or the intentional termination of
life as always wrong. It raises the pressing need for criteria to
distinguish between permissible and impermissible omissions of life-sustaining
means.
Traditionally, this distinction
has been drawn in terms of so-called ordinary and extraordinary
means of treatment. The distinction has a long history and was employed
by the Roman Catholic Church to deal with the problem of surgery
prior to the development of antisepsis and anaesthesia. If a patient
refused ordinary means - for example, food - such refusal was regarded
as suicide, or the intentional termination of life. Refusal of extraordinary
means (painful or risky surgery, for example) on the other hand,
was not regarded as the intentional termination of life.
Today, the distinction between
life-sustaining means that are regarded as ordinary and obligatory
and those that are not is often expressed in terms of 'proportionate'
and 'disproportionate' means of treatment. A means is 'proportionate'
If it offers a reasonable hope of benefit to the patient: it is
'disproportionate' if It does not. (See Sacred Congregation for
the Doctrine of the Faith, 198O, pp.9-10.) Understood in this way,
the distinction between proportionate and disproportionate means
is clearly morally significant. But it is not, of course, a distinction
between means of treatment, considered simply as means of treatment.
Rather, it is a distinction between the proportionate or disproportionate
benefits different patients are likely to derive from a particular
treatment. The same treatment can thus be proportionate or disproportionate,
depending on the patient's medical condition and on the quality
and quantity of life the patient is likely to gain from its employment.
A painful and invasive operation, for example, might be an 'ordinary'
or proportionate' means if performed on an otherwise healthy 20-year-old
who is likely to gain a lifetime; it might well be considered 'extraordinary'
or 'disproportionate' if performed on an elderly patient, who is
also suffering from some other serious debilitating disease. Even
a treatment as simple as a course of antibiotics or physiotherapy
is sometimes judged to be extraordinary and non-obligatory treatment.
(See Linacre Centre Working Party, 1982, pp.46-8.)
This understanding of ordinary
and extraordinary means suggests that an agent who refrains from
using extraordinary means of treatment engages in passive euthanasia:
A withholds potentially life-sustaining treatment from B, for the
sake of B. Not everyone agrees, however, that the discontinuation
of extraordinary or disproportionate treatment is a case of passive
euthanasia. 'Euthanasia', It is often argued, involves the deliberate
or intentional termination of life. Administering a lethal injection,
or withholding ordinary life-sustaining means, are cases of the
intentional termination of life; withholding extraordinary means
and allowing the patient to die, is not.
The question then becomes:
what does the doctor 'do' when she withholds disproportionate life-sustaining
treatment from B, foreseeing that B will die as a consequence? And
how can this mode of bringing the patient's death about (or of allowing
the patient's death to occur) be distinguished, in terms of the
agent's intention, from the withholding of ordinary care on the
one hand, and the administration of a lethal injection on the other?
This brings us to the third
major theme on which the debate about euthanasia has focused:
the distinction between deaths that are directly intended and deaths
that are merely foreseen.
Intending death and foreseeing
that death will occur
If A administers a lethal
injection to B to end B's suffering, A has intentionally terminated
B's life. This case is uncontroversial, but has A also intentionally
terminated B's life when she seeks to alleviate 8's pain by Increasingly
large doses of drugs ('pyramid pain-killing') that she knows will
eventually bring about B's death? And has A terminated B's life
intentionally when she turns off the respirator that-sustains B's
life, knowing that B will die as a consequence?
Those who want to hold that
the first case is, but the second and third case is not, a case
of euthanasia or the intentional termination of life, have sought
to draw a distinction between these cases in terms of directly intended
results, and foreseen but non-intended consequences. Reflecting
on the administration of increasingly large and potentially lethal
doses of pain-killing drugs, the Vatican's Declaration on Euthanasia
thus holds that 'pyramid pain-killing' is acceptable because, in
this case, 'death is in no way intended or sought, even if the risk
of it is reasonably taken' (p.9). In other words, even if A foresees
that B will die as a consequence of what A does, B's death is only
foreseen and not directly intended. The direct intention is to kill
the pain, not the patient.
This distinction between
intended results and foreseen but non-intended further consequences
is formalized in the Principle of Double Effect (PDE); The
PDE lists a number of conditions under which an agent may 'allow
or 'permit' a consequence (such as a person's death) to occur, although
that consequence must not be intended by the agent. Thomas Aquinas,
with whom the PDE is said to have its origin, applied the distinction
between directly intended and merely foreseen consequences to actions
of self-defence. If a person is attacked and kills the attacker,
her intention is to defend herself, not to kill the attacker (Summa
Theologiae, II, ii).
Two main questions have been
raised regarding the intention/foresight distinction:
- Can a clear distinction
always be drawn between those consequences that an agent directly
intends and those that she merely foresees?
- Is the distinction, to
the extent that it can be drawn, morally relevant in itself?
Consider the first point
in the light of the following frequently cited example: A party
of explorers is trapped in a cave, in whose narrow opening a rather
fat member of the party is lodged, and the waters are rising. If
a member of the party explodes a charge of dynamite next to the
fat man, should we say that he intended the fat man's death or that
he merely foresaw it as a consequence of either freeing the party,
removing the fat man's body from the opening, or blowing him to
atoms?
If one wants to hold that
the fat man's death was clearly intended, in what way then is this
case different from the one where a doctor can administer increasingly
large doses of a pain-killing drug that will foreseeably bring about
the patient's death, without that doctor being said to have intended
the patient's death?
There are serious philosophical
problems in any systematic application of the intention/foresight
distinction, and the literature is replete with criticisms and refutations.
Nancy Davis discusses some of this literature in the context of
deontological ethics (where the distinction is crucial) in Article
17, "contemporary deontology" [in P. Singer (ed.) A Companion
to Ethics]. Assuming that the difficulties can be overcome, the
next question presents itself: is the distinction between directly-intended
results and merely foreseen consequences morally relevant in itself?
Does it matter, morally, whether a doctor when administering what
she believes to be a lethal drug merely intends to relieve the patient's
pain, or whether she directly intends to end the patient's life?
Here a distinction is sometimes
drawn between the goodness and badness of agents: that it is the
mark of a good agent that she not directly intend the death of another
person. But even if a distinction between the goodness and badness
of agents - can sometimes be drawn in this way, it is of course
not clear that it can be applied to euthanasia cases. In all euthanasia
cases, A seeks to benefit B, thus acting as a good agent would.
Only if it is assumed that there is a rule which says 'A good agent
must never directly intend the death of an innocent', does the attempt
to draw the distinction make sense - and that rule then lacks a
rationale.
Conclusion
The above distinctions represent
deeply felt differences. Whether or not these differences are morally
relevant, and if so on what grounds, is a debate that is still continuing.
There is, however, one other aspect of the euthanasia debate
that has not yet been touched on. People frequently agree that
there may be no intrinsic moral difference between active and passive
euthanasia, between ordinary and extraordinary means, and between
deaths that are directly intended and deaths that are merely foreseen.
Nonetheless, the argument is sometimes put that distinctions such
as these represent important lines of demarcation as far as public
policy is concerned.
Public policy requires
the drawing of lines, and those drawn to safeguard us against unjustified
killings are among the most universal. Whilst it is true that such
lines may appear arbitrary and philosophically troubling, they are
nonetheless necessary to protect vulnerable members of society against
abuse. The question is, of course, whether this kind of reasoning
has a sound basis: whether societies that openly allow the intentional
termination of life under some circumstances will inevitably move
into a dangerous 'slippery slope' that will lead from justified
to unjustified practices.
In its logical version, the
'slippery slope' argument is unconvincing. There are no logical
grounds why the reasons that justify euthanasia - mercy and respect
for autonomy - should logically also justify killings that are neither
merciful nor show respect for autonomy. In its empirical version,
the 'slippery slope' argument asserts that justified killings will,
as a matter of fact, lead to unjustified killings. There is little
empirical evidence to back up this claim. Whilst the Nazi 'euthanasia'
programme is often cited as an example of what can happen when a
society acknowledges that some lives are not worthy to be lived,
the motivation behind these killings was neither mercy nor respect
for autonomy: it was, rather, racial prejudice and the belief that
the racial purity of the Volk required the elimination of certain
individuals and groups. As already noted, in the Netherlands a 'social
experiment' with active voluntary euthanasia is currently in progress.
As yet there is no evidence that this has sent Dutch society down
a slippery slope.
