What's wrong with designer children, bionic athletes, and genetic engineering.

In Better than Human, noted bioethicist Allen Buchanan grapples with the ethical dilemmas of the medical revolution and biomedical enhancements. One problem, he argues, is that the debate over these enhancements has divided into polar extremes--into denunciations of meddling in the natural order, or else a heady optimism that we can cure all that ails humanity. In fact, Buchanan notes, the human genome has always been unstable, and intervention is no offense against nature.

This article examines arguments concerning enhancement of human persons recently presented by Michael Sandel (2004). In the first section, I briefly describe some of his arguments. In section two, I consider whether, as Sandel claims, the desire for mastery motivates enhancement and whether such a desire could be grounds for its impermissibility. Section three considers how Sandel draws the distinction between treatment and enhancement, and the relation to nature that he thinks each expresses. The fourth section examines Sandel's views about (...) parent/child relations and also how enhancement would affect distributive justice and the duty to aid. In conclusion, I briefly offer an alternative suggestion as to why enhancement may be troubling and consider what we could safely enhance. (shrink)

As cognitive neuroscience has advanced, the list of prospective internal, biological enhancements has steadily expanded. Education and training, as well as the use of external information‐processing devices, may be labeled as “conventional” means of cognition enhancement (CE). They are often well established and culturally accepted. By contrast, methods of enhancing cognition through “unconventional” means, such as ones involving deliberately created nootropic drugs, gene therapy, or neural implants, are nearly all to be regarded as experimental at the present time. Transcranial magnetic (...) stimulation (TMS), genetic interventions, brain‐computer interfaces and new senses are highly experimental and unlikely to be important over the next 15 years. Many of the concerns about enhancement are nonspecific to the tools used to achieve it, which means that enhancement–ethic scrutiny should also apply to nonbiological external enhancements. (shrink)

The treatment-enhancement distinction draws a line between services or interventions meant to prevent or cure conditions that we view as diseases or disabilities and interventions that improve a condition that we view as a normal function or feature of members of our species. The line drawn here is widely appealed to in medical practice and medical insurance contexts, as well as in our everyday thinking about the medical services we do and should assist people in obtaining.

In their excellent book Disadvantage, Jonathan Wolff and Avner de-Shalit (hereafter: the Authors) state that their aim “is to provide practical guidance to policy makers by providing a version of egalitarian theory which can be applied to actual social policy.”1 This is a worthy project and their execution of it is full of insight. However, I doubt that they succeed in fulfilling their stated aim.
