There’s probably not a parent in the world who hasn’t wished
for a magic wand that would make a sad child happy, or transform an unruly child
into a civil one. And history is littered with the myriad methods cultures have
applied to bend their members toward a particular definition of human nature.
But for the first time in human history, we are confronted
with an entirely new approach to altering human nature, one that could have
great benefits but could also carry great risks. Geneticists are closing in on
a mythic power that humans once only dreamed of, the power to alter the genetic
materials we pass on to future generations by engaging in “inheritable genetic modification”
(IGM) or “germline engineering.” (In contrast, “somatic engineering” affects
only the person being treated, without producing changes in patients’ germ
cells—their eggs or sperm—that can be passed on to future generations.)
The personal, social, and political dangers inherent in
asserting control over the human germline were well apparent when Aldous Huxley
published his prophetic novel Brave New World in 1932. At that time,
wellintentioned, highly educated scientists and politicians were wielding the
surgeon’s scalpel to realize a vision of genetically “improving” human nature
by eliminating “bad genes” from the human gene pool.
Humanity needs a crash course in the science and politics of
the new human genetic technologies. We need to distinguish benign applications from
pernicious ones, and we need to adopt policies affirming the former and
proscribing the latter. We need to repudiate eugenic political ideologies and deepen
our commitment to the integrity of the human species and the dignity of all
people. We need to do this on a global scale and within less than a
decade. Two new technologies are of
critical concern: reproductive cloning and inheritable genetic modification and
reproductive cloning is the creation of a genetic near-duplicate of an existing
person. If I cloned myself, would the child be my son or my twin brother? In truth,
he would be neither. He would be a new category of biological relationship—my
clone. Opposition to reproductive cloning is nearly universal, and the United
Nations has begun negotiations on an international treaty to ban it.
Inheritable genetic modification (IGM) means modifying the
genes we pass to our children. Most people intuitively understand that if IGM
were allowed it would change forever the nature of human life. People would
quite literally have become artifacts. If cloning is the atomic bomb of the new
human genetic technologies, IGM is the multi-megaton hydrogen bomb. Only the
most egotistical or deluded would want to clone themselves, but if IGM were allowed
even many who are appalled at the prospect of using it would feel compelled to
do so, lest their children be left behind in the new techno-eugenic rat-race. Once
we begin genetically modifying our children, where would we stop? If it was
acceptable to engineer one gene, why not two? If two, why not twenty, or two
hundred? IGM would put into play wholly unprecedented biological, social, and
political forces that would feed back upon themselves with impacts quite beyond
our ability to foresee, much less control.
What policies do we need? We need domestic and international
bans on reproductive human cloning and inheritable genetic modification, and effective,
accountable regulation of all other genetic technologies. At the same time we
need to affirm the many beneficial applications of genetic science—in diagnostics,
therapeutics, pharmaceutical development, and other medical fields—and to
ensure that these are available to all people, regardless of economic status or
geography.
