This issue has always upset myself to become paranoid towards this subject. I'm curious what you all think about this subjective thought.
Human enhancement has emerged in recent years as a b topic in ethics. With continuing advances in science and technology, people are beginning to realize that some of the basic parameters of the human condition might be changed in the future. One important way in which the human condition could be changed is through the enhancement of basic human capacities. If this becomes feasible within the lifespan of many people alive today, then it is important now to consider the normative questions raised by such prospects. The answers to these questions might not only help us be better prepared when technology catches up with imagination, but they may be relevant to many decisions we make today, such as decisions about how much funding to give to various kinds of research. Enhancement is typically contra-posed to therapy. In broad terms, therapy aims to fix something that has gone wrong, by curing specific diseases or injuries, while enhancement interventions aim to improve the state of an organism beyond its normal healthy state. However, the distinction between therapy and enhancement is problematic, for several reasons.
First, we may note that the therapy-enhancement dichotomy does not map onto any corresponding dichotomy between standard-contemporary-medicine and medicine-as-it-could-be-practised-in-the-future. Standard contemporary medicine includes many practices that do not aim to cure diseases or injuries. It includes, for example, preventive medicine, palliative care, obstetrics, sports medicine, plastic surgery, contraceptive devices, fertility treatments, cosmetic dental procedures, and much else. At the same time, many enhancement interventions occur outside of the medical framework. Office workers enhance their performance by drinking coffee. Make-up and grooming are used to enhance appearance. Exercise, meditation, fish oil, and St John’s Wort are used to enhance mood.
Second, it is unclear how to classify interventions that reduce the probability of disease and death. Vaccination can be seen as an immune system enhancement or, alternatively, as a preventative therapeutic intervention. Similarly, an intervention to slow the aging process could be regarded either as an enhancement of healthspan or as a preventative therapeutic intervention that reduces the risk of illness and disability.
Third, there is the question of how to define a normal healthy state. Many human attributes have a normal (bell curve) distribution. Take cognitive capacity. To define abnormality as falling (say) two standard deviations below the population average is to introduce an arbitrary point that seems to lack any fundamental medical or normative significance. One person might have a recognizable neurological disease that reduces her cognitive capacity by one standard deviation (1σ), yet she would remain above average if she started off 2σ above the average. A therapeutic intervention that cured her of her disease might cause her intelligence to soar further above the average. We might say that for her, a normal healthy state is 2σ above the average, while for most humans the healthy state is much lower. In contrast, for somebody whose “natural” cognitive capacity is 2σ below the average, an intervention that increased it so that she reached a point merely 1σ below the average would be an enhancement. As a result, an enhanced person may end up with lower capacity than even an unenhanced person with subnormal cognitive functioning; and therapeutic treatment may turn a merely gifted person into a genius. In cases like these, it is hard to see what ethical significance attaches to the classification of an intervention as therapeutic or enhancing. Moreover, in many cases it is unclear that there is a fact of the matter as to whether the complex set of factors determining a person’s cognitive capacity is pathological or normal. Does having a gene present in 20% of the population that correlates negatively with intelligence constitute a pathology?
Having a large number of such genes might make an individual cognitively impaired or even ********, but not necessarily through any distinctive pathological process. The concepts of “disease” or “abnormality” may not refer to any natural kind in this context. These concepts are arguably not useful ways of characterizing a constellation of factors that are normally distributed in a population, as are many of the factors influencing cognitive capacity or other candidate targets for enhancement. A concept that defined enhancement as an improvement achieved otherwise than by curing specific disease or injury would inherit these problems of defining pathology.
Fourth, capacities vary continuously not only within a population but also within the lifespan of a single individual. When we mature, our physical and mental capacities increase; as we grow old, they decline. If an intervention enables an 80-year-old person to have the same physical stamina, visual acuity, and reaction time as he had in his twenties, does that constitute therapy or enhancement? Either alternative seems as plausible or natural as the other, suggesting again that the concept of enhancement fails to pick out, in any clear or useful way, a scientifically significant category.
Fifth, we may wonder how “internal” an intervention has to be in order to count as an enhancement (or a therapy). Lasik surgery is a therapy for poor vision. What about contact lenses? Glasses? Computer software that presents text in an enlarged font? A personal assistant who handles all the paperwork? Without some requirement that an intervention be “internal”, all technologies and tools would constitute enhancements in that they give us capacities to achieve certain outcomes more easily or effectively than we could otherwise do. If we insist on an internality constraint, as we must if the concept of enhancement is not to collapse into the concept of technology generally, then we face the problem of how to define such a constraint. If we believe that enhancements raise any special ethical issues, we also face the challenge of showing why the particular way we have defined the internality constraint captures anything of normative significance.
Sixth, even if we could define a concept of enhancement that captured some sort of unified phenomenon in the world, there is the problem that is ourselves to accept this concept that might take over the world some-day.
