The Case Against Perfection: Ethics in the Age of Genetic Engineering

[This is a review that I wrote and posted on my blog: http://nat99.blogspot.com/ ]

Reckless hubris on the road to “perfection”

This little book does a nice job of laying out many of the arguments that support genetic “enhancement” and then takes them apart piece by piece from a philosophical perspective. But unfortunately, Sandel neglects to highlight some of the strongest arguments against such offspring-engineering:

Designing one’s offspring for “success” makes assumptions about what “success” entails. The unwritten subtext is usually “financial success,” but is it the parent’s job to build cogs for the empire? Is it one’s destiny and obligation to function in as utilitarian a manner as possible? Does this not show more make a mockery of “the pursuit of happiness”? Can the happiness of one ever be defined by another?

How can autonomy not be lost when one person overlays their values onto another? Sandel discounts the argument that such bioengineering takes autonomy from its object, but in deciding what features to “enhance” in the building of another person, value judgments are inescapable, and making such choices on behalf of another is by definition a violation of that other’s autonomy. What gives anyone the right to instill math and engineering skills into someone whose temperament better suits them for life as a poet or naturalist? Or even to add height to one who might have been more physically coordinated at their natural height?

Is there an implicit ownership of the subject of one’s design? What happens when an offspring subsequently does not meet the parent’s expectations “after all we spent on designing you”?

Will a child have recourse against “parental malpractice”? If the parent’s choices result in harm, or a parent is negligent in opting for available enhancements, will the child be allowed to seek damages?

Changes in a single gene will have multiple effects via such genetic mechanisms as pleiotropy and epistasis, and these secondary effects can be impossible to predict. For example, what if an increase in growth hormone intended to increase the height of one’s child also shortens their lifespan by five years, or increases their odds of developing cancer, or decreases their IQ by 5 percent? Is there any way to discover all possible outcomes, and would the parent have the right to discount such downsides as being of negligible import? Or, what if a genetic manipulation intended to improve an offspring’s math ability resulted in a 5 percent increase in the chances of the child becoming schizophrenic, or dyslexic, or less attractive? Is the parent morally justified in taking the inevitable risks of their intended enhancement creating unforeseen deficits of any sort?

There is a lesson to be taken from our experience with the unintended consequences that have been observed in the development of our chemical industry; we would be well-advised to comprehend that mucking about in genomes has the potential for unintended consequences exceeding those created by the chemists by many orders of magnitude. Do we really want to bestow that legacy onto the generations that follow us, as we selfishly try to give our own children a leg up in the competition they will face? Do we really believe ourselves to be competent “designers”? show less

In this little volume, Michael Sandel, Professor of Government at Harvard, discusses the ethical arguments surrounding genetic engineering. Is it OK to "cure" genetic diseases? What about enhancing IQ, artistic or athletic ability, overall health? What are the arguments for and against "designer children"? Is eugenics OK as long as it's voluntary? What about embryonic stem cell research? Sandel raises these questions and presents the arguments pro and con in a very readable and thought-provoking way.

This book had great potential and started off so well.... but never really lived up to its promise. Although the author raised many interesting points about genetic manipulation and the ethics about selecting for short term improvements, it felt like he never really got into the heart of the matter. At first I thought this was because of the brevity of the book, but Sandel managed to get into much meatier levels of dicussion in an appended chapter on stem cell research. It really felt like this book only skimmed the surface of the arguments about genetic engineering. That's probably fine for a lot of people but I was hoping for a dramatic dive into the centre rather than a surface level discussion.

Excerpt of my review:

The technology of genetic engineering is one cultural location where the politics of reproductive freedom and disability rights come together. These are not the only issues, or the only place these two interests intersect, but it is probably the most culturally compelling in our time.

¿Que tiene de malo manipular nuestra naturaleza? ¿Dónde están las líneas rojas, si las hay? El filósofo Michael Sandel trata de responder a esta pregunta a traves de un ameno pero profundo repaso del campo de la bioetica.
"Contra la perfección" explora estos y otros dilemas morales relacionados con la búsqueda de nuestro propio perfeccionamiento. Michael Sandel argumenta que la búsqueda de la perfección es imperfecta por razones que van más allá de la seguridad y de la equidad, y nos lleva más allá de los familiares terminos del discurso político para mostrarnos que la revolución genetica transformará el modo en que se discute sobre cuestiones eticas y obligará a reintroducir las cuestiones de orden espiritual en el show more centro del debate político. show less
