"I was convinced that there was still plenty
of time."(1)
With those words the author Aldous Huxley looked back
to 1931, and the publication of his famous novel Brave New World. Huxley's
vision of an oppressive culture of total authoritarian control and social
engineering was among the most shocking literary events of the twentieth
century.
But just 27 years after the publication of Brave New
World, Huxley was already aware of his underestimation of the threat represented
by modern technocratic society. News that scientists
had cloned an adult sheep from non-reproductive cells shook
the scientific community, but prompted an earthquake of concern in the
larger culture.
The cloning of the sheep by Dr. Ian Wilmut's team
in Scotland raises a host of ethical, legal, and social issues which will
take time to untangle. Yet, even as this reality began to sink into our
cultural consciousness, further reports of the cloning of monkeys from
embryo cells and attempts at human cloning
raised the sense of ethical crisis.
The Cloning of Animals
and the Ethics of Dominion
The simple fact that an adult sheep had been produced
through cloning was a graphic indication of the remarkable
advances made in the field of genetics in recent years. The
achievement of a cloned mammal -- genuinely cloned from a non-reproductive
cell -- was thought to be years away.
Yet Wilmut and his colleagues apparently moved the
schedule ahead and achieved a genuine scientific
breakthrough. The proposed use of the cloned sheep and the
impetus behind the experiment is pharmaceutical research, but this limited
purpose is but a hint of the countless purposes to which the technology
can be directed. "Dolly," as the sheep is known, is the face
of the future as the technology of cloning is advanced and applied.
What Are The Ethical Implications
Of Cloning Animals?
At first glance, this question appears no more complicated
than related questions concerning animal husbandry and breeding. After
all, selective breeding designed to enhance the quality of stocks and
herds predates the development of genetics as a science.
Once the basic patterns of genetic inheritance were
observed, techniques intended to enhance genetic quality quickly followed.
Over the past two decades, this has exploded into international agribusiness,
and most modern animals produced for human
consumption bear the marks of some genetic
intervention.
Genetic enhancements such as the practice of "twinning"
cattle embryos are now practiced wholesale in developed nations. But the
arrival of "Dolly" represents an entirely new development toward
the artificiality of animal life at the hands of human engineers.
According to the Bible, human beings are granted and
assigned a dual responsibility by the Creator -- dominion and stewardship.
Human beings, made in the image of God, are to exercise dominion and "rule
over the fish of the sea and over the birds of the sky and over the cattle
and over all the earth, and over every creeping thing that creeps on the
earth."(2)
This extensive rule sets the human being apart from
the rest of creation, and the other creatures. This rulership is translated
into the intentional use of animals to human ends and the elevation of
human needs and purposes above all other creatures. But the dominion granted
to human beings is not inherently ours, but is a delegated rulership.
We rule over the animals by the authority of our Creator, and thus we
will answer for our stewardship of our rulership.
What does this suggest
about the issue of cloned animals?
First, the acknowledgment of our delegated dominion
should make clear that our rulership is limited.
We are not to take the
authority of the Creator as our own.
Second, this principle of a delegated rulership should
serve as a warning concerning the increasing artificiality of animal life
at human hands.
The increasing use of unnatural means of reproduction
leads automatically to a sense of engineered life forms as human creations.
Put bluntly, we were not commanded or authorized to create new forms of
life as extensions of our own designs and ego.
Nightmarish scenarios of unforeseen consequences
are easily imaginable.
Further, the issue of cloned mammals also threatens
the biodiversity God clearly intended as a mark of His creation. Cloned
animals repeat the genetic code of the host animals, avoiding the necessary
genetic mixing by natural reproduction. Performed on a wide scale, this
could threaten to harm species, or even threaten their survival from disease.
The intricate questions of ethical means and ends
revolve around every aspect of animal cloning. This is not a simple issue
of a new genetic technology.
The ethical issues of
animal cloning are real and unavoidable.
Without question, the development of cloning may provide
advances in therapeutic technologies which will benefit human beings as
well as animals.
Nevertheless, the technology of cloning also raises
the specter of transgenic animals -- crossing species and creating customized
new animal forms. Again, the Christian worldview warns us that our stewardship
and dominion of other creatures is to be exercised within
limits imposed by the Creator.
Many arguments on behalf of human "co-creation"
with God are not biblically sustainable, and indicate creaturely over-reaching
and hubris. Human beings are assigned responsibility for the care, use,
and enjoyment of animal creatures, but we are not granted license for
their mechanistic manipulation, transgenic innovation, or ruthless violation.
One need not accept the ideology of the animal rights
movement in order to question the moral character of these new technologies
which threaten the integrity of animal life. At the same time, abstract
claims of the integrity of animal life cannot be posed in terms of ultimacy.
The distinction between human beings and the other
living beings is central to the biblical text. Spiritual value is assigned
to human life in a sense that is totally foreign and alien to animal life.
Animal life is certainly not without value, as attested by the "goodness"
of animal creation by the verdict of the Creator. But animal life cannot
be assigned the highest value, for such would be an inversion of the biblical
hierarchy of value and moral responsibility.
The Cloning of Humans
and the Reproductive Revolution
Though the cloning of a sheep was the proof that cloning
could be achieved, few thoughtful persons could keep their minds on the
lamb. The cloning of human beings -- long limited
to the domain of science fiction -- now appeared to be an impending
reality.
Ian Wilmut accepted the fact that cloning humans would
be possible. "There is no reason in principle why you couldn't do
it," he acknowledged. Yet he added, "All of us would find that
offensive."(3)
Though his first statement remains to be demonstrated,
his second statement is blatantly false. It is simply not true that all
of us would find the cloning of human beings to be offensive. Indeed,
an editorial published in Nature advised that human cloning "is likely
to be achievable any time from one to ten years from now. Ethical constraints
aside, there are even some rare genetic and medical disorders for which
it would be a desirable way for a couple to produce offspring."(4)
Bioethicist John Robertson agrees, adding that the
cloning of a dying child or infertile adults might be morally justified.(5)
Others, such as John Fletcher, a former ethicist for the National Institutes
of Health, assert that the cloning of a baby designed to provide a tissue-matched
organ or bone marrow could also be justified. "The reasons for opposing
this are not easy to argue," Fletcher commented.(6)
The claim that the cloning of a human being could
take place in the next few years came as a surprise to the general public.
The idea of cloning a human being was quickly championed by some of the
more eager proponents of genetic technologies. Others were more skeptical,
doubting that the difficulty of cloning a human would be comparable to
cloning a sheep.
Nevertheless, the technology is basically the same,
and the achievement of a cloned human being is not likely
to be far in our future, if it has not occurred already. This
is an issue of immediate, urgent, and universal importance. The cloning
of a human being represents a radical break with the human past, and with
the established patterns of human life.
The very possibility of human cloning is repulsive
to many persons. Harold Varmus, director of the National Institutes of
Health, suggested that the notion of cloning a human being would be "repugnant
to the American public."(7) Harvard neurobiologist Lisa Geller, who
admitted that she could make no ethical distinction between in vitro fertilization
and cloning, nevertheless confessed: "I admit is makes my stomach
feel nervous."(8)
The cloning of a human brings to mind the sterile,
dehumanizing images of Huxley's Brave New World, with its fertilizing
rooms, decanting chambers, and embryo stores representing the technological
perfection of artificial human reproduction. The reproductive revolution
has already thrown a host of difficult ethical issues on the national
agenda, but the genetic revolution is
perhaps the greatest ethical challenge of the new millennium.
That nervous stomach to which Geller admitted is about
all the secular worldview can offer in response to this issue.
Having denied the existence and authority of God the
Creator, all that remains for modern secularists is the artificial morality
of an ad hoc ethic. Any opposition to cloning -- human or otherwise -- is
merely arbitrary. Business Week was positively ecstatic about the possibilities
of cloning, and stated editorially: "The world should embrace the
biological revolution, not cringe from it."(9)
Yet, incongruous though it may seem, the same editorial
warned: "There is no question that the notion of individuals cloning
themselves is not only repugnant but also raises important questions."
Clearly, Business Week's embrace of the biological
revolution is not unconditional -- at least not yet -- but their editorial
opposition to human cloning appears merely arbitrary and superficial.
The possible development of human cloning raises a host of ethical quandaries.
Who would be the "parents" of a cloned child? In an age of patented
forms of life, could a cloned being be "owned," at least in
genetic pattern?
Will parents seek to clone children in order to provide
tissues, organs, or bone marrow for transplant into another child? These
are but a few of the many pressing questions which will demand address.
The secular worldview provides only tentative and provisional answers.
Does the Christian worldview offer a more substantial
basis for the ethical evaluation of human cloning? I will argue that the
Christian worldview alone can provide us with an ethical context and authority
adequate to this task
In the Image of God: Human
Beings and the Purpose of God
The biblical creation account presents the creation
of human beings as the pinnacle of God's creative purpose. After creating
the world and filling it with living creatures, God purposed to create
human beings.
The human creature -- set apart from all other creatures -- would
bear the Imago Dei, the image of God. While the exact nature of the image
of God in the human creature is not identified in detail, it clearly represents
the spiritual character and capacity God established in us, and it sets
the human creature apart from all other living beings.(10)
Though the image of God in human beings has been corrupted
by sin, it has not been removed, and this image is an essential mark of
true humanity. Each human being is a special creation of God, made in
His own image. Human beings share certain common characteristics and features,
as well as a common form with specializations, but each is unique by the
design of the Creator.
The status of human beings as created beings, each
unique but all bearing the image of God, establishes a foundation for
theological understanding. The fact that the precise character of the
image of God in humanity is unknown to us does not mean that we have no
general knowledge of its meaning. The Reformed tradition has identified
knowledge, righteousness, and holiness as a triad of qualities representing
the image of God.(11)
Each of these qualities establishes the human as qualitatively
distinct from other creatures. Thomas Aquinas, the great synthesizer of
the medieval tradition, defined the image of God as a function and capacity
of human consciousness or intellect. This capacity exists in three stages,
argued Thomas, rising from the potential knowledge of God, to the actual
acknowledge of God, to the perfect knowledge of God.
John Calvin tied the concept of the image of God to
the human capacity to glorify God, but accepted that every part of the
human being is marked in some sense by the image, even though it is corrupted
by sin. Herman Bavinck stated the issue clearly: "Man does not simply
bear or have the image of God; he is the image of God."(12)
He continues: From the doctrine that man has been
created in the image of God flows the clear implication that that image
extends to man in his entirety. Nothing in man is excluded from the image
of God. All creatures reveal traces of God, but only man is the image
of God. And he is that image totally, in soul and body, in all faculties
and powers, in all conditions and relationships. Man is the image of God
because and insofar as he is true man, and he is man, true and real man,
because and insofar as he is the image of God.(13)
Thus, the biblical view of human value is rooted in
the revealed knowledge that we are made in God's image, and thus are image-bearers
by our very nature. Bavinck's reminder that this is essential to true
humanity is echoed by Anthony Hoekema's insistence that the concept of
the image of God is the "most distinctive feature of the biblical
understanding of man."(14)
Without the knowledge of the divine image, man does
not know himself for who he is. This makes clear the decisive distinction
between the biblical and secular conceptions of human nature and value.
The naturalistic understanding of humanity central
to modernity accepts no theistic referent of value. Human beings are cosmic
accidents -- the fortuitous by-products of blind evolutionary process. As
James Watson reflected, he came early to accept Linus Pauling's simple
statement, "We came from chemistry."(15)
Any value thus ascribed to human life is arbitrary
and tentative, and necessarily self-referential. This explains why contemporary
secular debates concerning the value or sanctity of human life are so
inherently confused. We will ascribe value to ourselves by an act of the
will. But, as the murderous twentieth century has shown, those who ascribe
value to human life by an act of the will can deny that same value by
a similar act of the will.
According to the biblical revelation, human beings,
like all of creation, were created in order to glorify God. But humans
were created with a distinct and unique capacity to know, reverence, worship,
and glorify the Creator. He made human beings, male and female, of his
own good pleasure, in his own image, and to his own sovereign purpose.
Thus, human beings are not mere biological artifacts,
nor accidental forms of life. The special, purposeful, and direct creation
of every human being in the image of God is central to the Christian worldview.
Modernity's rejection and refutation of that revealed knowledge has set
the stage for the rise of abortion, euthanasia, genetic manipulation,
infanticide, and even genocide -- all in the name of social responsibility
and personal autonomy.
Genetic Manipulation and
the Eugenic Temptation
Since the rise of genetic knowledge, the eugenic temptation
has always been with us. As Daniel Kevles notes, the desire to breed better
humans goes back as far as Plato, though Plato had no conception that
genetic knowledge would one day put that goal within human reach.(16)
Francis Galton's term eugenics (literally,
"good in birth") is now a part of our cultural vocabulary, and
the eugenic reality is on the front line of our cultural crisis.
The temptation to conceive
human breeding in eugenic terms is powerful and, in one sense, virtually
unavoidable.
No thoughtful person would suggest or recommend casual
disregard of genetic knowledge regarding, for example, inherited genetic
disorders such as Tay-Sach's disease.
But the advent of genetic testing and the exploding
knowledge of the human genotype present entirely new eugenic opportunities
and ethical challenges. The crusades of the early eugenicists were directed
at limiting the reproduction of those persons or races considered "inferior"
and the enhancement of the human species by the intentional breeding of
those considered racially or individually "superior."
Eugenic experiments, movements, and theories were
common in the early twentieth century in both Europe and the United States,
and these often were presented as essentially hygienic and progressive
in purpose.
Widespread knowledge of the eugenics-driven genocide
of the Nazi regime pushed eugenics outside the pale of acceptable science
and medicine in the western democracies -- at least until the rise of the
new genetic knowledge after 1953, and the identification by James Watson
and Francis Crick of the molecular code of DNA. Now, the eugenic temptation
is back, armed with knowledge and technologies unimagined by the Nazi
doctors and their eugenic compatriots.
The Human Genome Project
represents the Manhattan Project of human genetics, and will present humanity
with the greatest ethical challenges of the coming century.
Though this is seldom articulated or acknowledged
in public, genetic testing currently available is used by some parents
to decide if a developing fetus is worthy of life.
