Last week’s news that scientists had cloned a sheep sent
academics and the public into a panic at the prospect that humans might be next.
That’s an understandable reaction. Cloning is a radical challenge to the most
fundamental laws of biology, so it’s not unreasonable to be concerned that it
might threaten human society and dignity. Yet much of the ethical opposition
seems also to grow out of an unthinking disgust—a sort of "yuk factor. " And
that makes it hard for even trained scientist sand ethicists to see the matter
clearly. While human cloning might not offer great benefits to humanity, no one
has yet made a persuasive case that it would do any real harm, either.
Theologians contend that to clone a human would violate human dignity.
That would surely be true if a cloned individual were treated as a lesser being,
with fewer rights or lower stature. But why suppose that cloned person wouldn’t
share the same rights and dignity as the rest of us A leading lawyer-ethicist
has suggested that cloning would violate the "right to genetic identity." Where
did he come up with such a right It makes perfect sense to say that adult
persons have a right not to be cloned without their voluntary, informed consent.
But if such consent is given, whose "right" to genetic identity would be
violated Many of the science-fiction scenarios prompted by the
prospect of human cloning turn out, upon reflection, to be absurdly improbable.
There’s the fear, for instance, that parents might clone a child to have "spare
parts" in case the original child needs an organ transplant. But parents of
identical twins don’t view one child as an organ farm for the other. Why should
cloned children’s parents be any different Another disturbing
thought is that cloning will lead to efforts to breed individuals with genetic
qualities perceived as exceptional (math geniuses, basketball players). Such
ideas are repulsive, not only because of the "yuk factor" but also because of
the horrors perpetrated by the Nazis in the name of eugenics. But there’s a vast
difference between "selective breeding" as practiced by totalitarian regimes
(where the urge to propagate certain types of people leads to efforts to
eradicate other types) and the immeasurably more benign forms already practiced
in democratic societies (where, say, lawyers freely choose to marry other
lawyers ). Banks stocked with the frozen sperm of geniuses already exist. They
haven’t created a master race because only a tiny number of women have wanted to
impregnate themselves this way. Why think it will be different if human cloning
becomes available So who will likely take advantage of
cloning Perhaps a grieving couple whose child is dying. This might seem
psychologically twisted. But a cloned child born to such dubious parents stands
no greater or lesser chance of being loved, or rejected, or warped than a child
normally conceived. Infertile couples are also likely to seek out cloning. That
such couples have other options (in vitro fertilization or adoption) is not an
argument for denying them the right to clone. Or consider an example raised by
Judge Richard Posner: a couple in which the husband has some tragic genetic
defect. Currently, if this couple wants a genetically related child, they have
four not altogether pleasant options. They can reproduce naturally and risk
passing on the disease to the child. They can go to a sperm bank and take a
chance on unknown genes. They can try in vitro fertilization and dispose of any
afflicted embryo—though that might be objectionable, too. Or they can get a male
relative of the father to donate sperm, if such a relative exists. This is one
case where even people unnerved by cloning might see it as not the worst
option. Even if human cloning offers no obvious benefits to
humanity, why ban it In a democratic society we don’t usually pass laws
outlawing something before there is actual or probable evidence of harm. A
moratorium on further research into human cloning might make sense, in order to
consider calmly the grave question it raises. If the moratorium is then lifted,
human cloning should remain a research activity for an extended period. And if
it is ever attempted, it should — and no doubt will — take place only with
careful scrutiny and layers of legal oversight. Most important, human cloning
should be governed by the same laws that now protect human rights. A world not
safe for cloned humans would be a world not safe for the rest of us.
