It is a "given" in discussions of genetic
engineering that no sensible person can be in favour of eugenics. The
main reason for this presumption is that so much horror, misery, and
mayhem have been carried out in the name of eugenics in the 20th
century that no person with any moral sense could think
otherwise.1-3 In fact, the abysmal history of murder and
sterilisation undertaken in the name of race hygiene and the
"improvement" of the human species again and again in this century
is so overpowering that the risk of reoccurrence, sliding down what has
proved time and time again to be an extremely slick, slippery slope,
does seem enough to bring all ethical argument in favour of eugenics to an end.
However, before dismissing any
favourable stance towards eugenics it is important to distinguish what
has happened in the past under the banner of eugenics and what might
happen in the future. It is important to distinguish between genetic
changes undertaken with respect to improving a group or population and genetic change that takes a single individual as its focus.
Summary points
The horrible abuses committed in the name of eugenics through
coercive policies imposed by governments have obscured the fact that
eugenic goals can be the subject of choice as well as coercion
In the rush to map the human genome and reap the benefits of new
genetic knowledge it has become commonplace to argue that eugenic goals
will play no part in how new genetic knowledge is used
The moral case against voluntary choices to advance eugenic goals by
individuals or couples has not been persuasively made
Given the power and authority granted to parents to seek to improve or
better their children by environmental interventions, at least some
forms of genetic selection or alteration seem equally ethically
defensible if they are undertaken freely and do not disempower or
disadvantage children
Efforts to change the genetic makeup of a group or population almost always require third parties to be involved in the personal reproductive choices of individuals and couples. Someone besides the individuals making children has to set a policy and a standard. In our century these efforts have almost always incorporated force or coercion since individuals may not agree with the policy or third parties may seek to force their vision of improvement on an unwilling population.
It is, however, a different matter for couples to undertake their own efforts to use genetic technologies and knowledge to improve the potential of their offspring. Eugenics has not, until the advent of genetic engineering, offered this option. Efforts to change the inherited genetic makeup of a particular person may be the result of third party involvement, but it is far more likely that such efforts will be the result of individual reproductive choice.4 To put the point another way, population eugenics involves commanding people to produce desired genotypic or phenotypic traits. This sort of eugenics is not the same as allowing an individual or couple voluntarily to choose a heritable trait in their sperm, egg, embryo, or fetus, motivated by their view of what is good or desirable.
The most common arguments against any attempt to either avoid a trait
through germline genetic engineering or to create more children with
desired traits fall into three categories: worries about the presence
of force or compulsion, the imposition of arbitrary standards of
perfection,4 or inequities that might arise from allowing
the practice of eugenic choice.5 The first worry is not
one that seems insurmountable as an objection to allowing individual
choice about germline changes. The latter two may also not discount
eugenic choices.

Coercion |

Certainly it is morally objectionable for governments or institutions or any third party to compel or coerce anyone's reproductive behaviour. 1 3 The right to reproduce without interference from third parties is one of the fundamental freedoms recognised by international law and moral theories from a host of ethical traditions. However, the goals of obtaining perfection, avoiding disease, or pursuing health with respect to individuals need not involve coercion or force.
A couple may wish to have a baby who has no risk of inheriting
Tay-Sachs disease or transmitting sickle cell disease. Or they may want
a child with a particular hair colour or sex. If their choice is free
and informed then there is no reason to think that such a choice is
immoral on grounds of force or coercion.

The subjectivity of perfection |
|---|
|
|
|---|
Some who find the pursuit of perfection morally objectionable worry about more than coercion. They note that it is simply not clear which traits or attributes are properly perceived as perfect or optimal. The decision about what trait or behaviour is good or healthy depends on the environment, culture, and circumstances that a child will face. Stigma and prejudice need not be the inevitable result of choice.
Views about what is perfect or desirable in a human being are, more
often than not, matters of taste, culture, and personal experience. But
they are not always simply the product of subjective feelings. There
are certain traits
physical stamina, strength, speed, mathematical
ability, dexterity, and acuity of vision, to name only a few
that are
related to health in ways that command universal assent as to their
desirability. It would be hard to argue that a parent who wanted a
child with better memory or greater physical dexterity was simply
indulging his or her biases or prejudices. As long as people are not
forced to make choices about their children that are in conformity with
particular visions of what is good or bad, healthy or unhealthy, there
would seem to be enough consensus about the desirability of some traits
to permit parents to make individual choices about the traits of their
children in the name of their health. And if no coercion of compulsion
were involved it could even be argued that parents should be free to
pick the eyebrow shape or freckle pattern of their children or other
equally innocuous traits as long as their selection imposed no risk for the child, did not compromise the child's chance of maximising his or
her opportunities, or lead to parents becoming overly invested in
superficial aspects of the child's appearance or
behaviour.

A parent might concede that their vision of perfection is to some degree subjective but still insist on the right to pursue it. Since we accept this point of view with respect to child rearing, allowing parents to teach their children religious values, hobbies, and customs as they see fit, it would be difficult to reject it as overly subjective when matters turn to the selection of a genetic endowment for their child.
For many years cosmetic surgeons, psychoanalysts, and sports medicine
specialists have been plying their trades without all people with big
noses or poor posture feeling they need to visit specialists to have
these traits altered. Some people choose to avail themselves of these
specialists in the pursuit of perfection. Many do not. If there is a
slope from permitting individual choice of one's child's traits to
limiting the choices available to parents it is a slope that does not
start with individual choice. And if there is a problem of a slope then
it must be shown why it is morally permissible for parents to seek
betterment after a child is born but why such efforts are wrong if
genetic alteration is used. There is nothing terrible about
subjectivity in a decision to indulge preferences about the traits of
one's child as long as those preferences do nothing to hurt or impair
the child.

Equality |

|
|

Another objection to allowing eugenic desires to influence parenting is that this will lead to fundamental social inequalities.5 Allowing parental choice about the genetic makeup of their children may lead to the creation of a genetic "overclass" with unfair advantages over those who parents did not or could not afford to endow them with the right biological dispositions and traits. Or it may lead to homogenisation in society where diversity and difference disappear in a rush to produce only perfect people, leaving anyone with the slightest disability or deficiency at a distinct disadvantage. Equity and fairness are certainly important concepts in societies that are committed to the equality of opportunity for all. However, a belief that everyone deserves a fair chance may mean that society must do what it can to insure that the means to implementing eugenic choices are available to all who desire them. It may also mean that a strong obligation exists to try and compensate for any differences in biological endowment with special programmes and educational opportunities. It is hard to argue in a world that currently tolerates so much inequity in the circumstances under which children are brought into being that there is something more offensive or more morally problematic about biological advantages as opposed to social and economic advantages.
It is difficult to argue in a world that tolerates the creation of homogeneity through the parental selection of schools, music lessons, religious training, or summer camps that only environmentally engineered homogeneity is morally licit. The fact that those people with privileged social backgrounds go on to similar sorts of educational and life experiences does not seem sufficient reason to interfere with parental choice.
No moral principle seems to provide sufficient reason to condemn
individual eugenic goals. While force and coercion, compulsion and
threat have no place in procreative choice, and while individual decisions can have negative collective consequences, it is not clear
that it is any less ethical to allow parents to pick the eye colour of
their child or to try and create a fetus with a propensity for
mathematics than it is to permit them to teach their children the
values of a particular religion, try to inculcate a love of sports by
taking them to football games, or to require them to play the piano. In
so far as coercion and force are absent and individual choice is
allowed to hold sway, then presuming fairness in the access to the
means of enhancing our offsprings' lives it is hard to see
what exactly is wrong with parents choosing to use genetic knowledge to
improve the health and wellbeing of their offspring.
