Despite
the warnings, others have glibly declared we have nothing to fear from
this new technology. Objections to human genetic engineering, scoffs Ronald Bailey at “Reason,”
are “ethically nonsensical.” After basic health screenings, he writes,
“gene-edited kids can be released into the wild human gene pool with no
special worries about how they might effect [sic] future generations.”
His reasoning
behind this, unbelievably, is that mutations happen naturally all the
time, and we don’t panic about those. What he misses in this
proclamation is an essential aspect of bioethics: intent. The fact that
people die naturally doesn’t mean killing is okay.
The fact that people have disabilities doesn’t mean we should intentionally disable people. In fact, natural genetic mutations perfectly
illustrate how small changes in DNA can be devastating, and will be
passed from generation to generation. Just ask those who suffer from
hemophilia, or Tay–Sachs or Huntington’s disease.
If there is a
legitimate use for gene-editing, it’s in healing, not enhancing. But of
course, even that has to be done with the greatest caution, and only by
geneticists fully aware that even our best laid plans often fail, and in
this case, the consequences will last for generations.
Still, our
concerns must be more than pragmatic. Other reproductive technologies
have already been used to experiment on children without their consent,
and many of these folks are now speaking up with concerns we promised
ourselves they would never have.
Reproductive
ethics must fundamentally recognize that we don’t own our children. We
have no right to remake them. Whether or not the future of gene-editing
will look anything like the movies, the idea of engineering the next
generation to suit our preferences is definitely the definition of mad science.
