Who Will Take Advantage of Human Cloning?

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 reasonable to be concerned that it might be a preface to activities that will threaten human society and dignity.

Yet much of the moral opposition seems also to grow out of an automatic, unthinking disgust. This refusal to consider the issue logically makes it hard for even trained scientists and other experts to see the matter clearly. While human cloning might not offer great benefits to humanity, no one has yet made a convincing case that it would do any real harm, either.

Conservative spiritual leaders have claimed that cloning a human constitutes a gross attack on human dignity. That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower status. But why suppose that the laws that protect our rights and dignity would not be applicable to cloned persons? A leading lawyer has suggested that cloning would violate the "right to a unique 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 were given, whose "right" to genetic identity would be violated? Many of the vivid warnings of science-fiction concerning the prospect of human cloning turn out,
upon reflection, to be wildly improbable.

There's the fear, for instance, that parents might clone a child for the sake of having "surplus 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 desirable (math geniuses, soccer players, etc.). Such ideas are offensive, not only because of an unthinking disgust, but also because of the horrors carried out by the Nazis in the name of improving their race. But there's a vast difference between the breeding programs as practiced by some groups (where the urge to breed certain types of people leads to efforts to destroy other types) and the much more harmless forms already practiced in democratic societies (where, say, lawyers freely choose to have sexual relations with other lawyers).

Banks stocked with the frozen sperm of geniuses already exist, but they haven't created a master race because few women are queuing up to get pregnant this way. Why should we think it would be different if human cloning becomes available? So who will likely take advantage of cloning? Perhaps a couple whose child is dying. This might seem psychologically suspect.

But a cloned child born to such suspect parents stands no greater or lesser chance of being loved, or rejected, than a child created the normal way. Infertile couples are also likely to seek out cloning. That such couples have other options (artificially bringing egg and sperm together, or adopting a child) 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 unfortunate genetic defect.

Currently, if this couple wants a genetically related child, they have four not altogether pleasant options. They can reproduce naturally and resign themselves to the risk of passing on the disease to the child. They can go to a sperm bank and take a chance on unknown genes. They can bring egg and sperm together artificially and dispose of any affected baby before placing it in the mother, or before birth — though that might be objectionable, too.

Or they can get a male relative of the father to be a sperm donor, if such a relative exists. This is one case where even people bothered by creating a child under the lens of a microscope might see cloning as not the worst option. Even if human cloning offers no obvious benefits to mankind, why ban it? In a democracy we don't usually pass laws against something before there is actual or probable evidence of harm.

Before we go any further, it might make sense to require a temporary pause on research into human cloning in order to make a systematic enquiry into the grave questions it raises. When research into cloning is resumed, 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 under careful examination and layers of legal administration.

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.
