The advancement of progress in the fields of biology and technology, and by extension, the scion of these two fields – biotechnology – is generally lauded by experts and laypeople alike. Genetically modified foods, Dolly the sheep, stem cell research, and therapeutic cloning are just some of the breakthroughs in this field that have changed the scientific landscape, drawing attention to the past, present, and even potential future exploits of men and women. women involved in biotechnology. Mainly because it is becoming increasingly clear that the field may, in the near future, extend beyond therapy to human enhancement. With the possibility of such expansion in sight, it might be prudent to ask whether or not such improvement is morally and ethically desirable in the context of human nature and even nature itself. And although transhumanists, advocates of enhancement, themselves agree that there are concerns such as potential health danger, technological difficulties or impact on the environment linked to human enhancement, their counterparts on the bioconservative side of the gap believe there is much more to worry about. Some even argue that the idea of ​​human improvement beyond therapy, or in other words making us “better than good”1 is inherently flawed. In any case, if human improvement in its many forms became commonplace, it would surely “affect the rate of human intellectual, material, and political progress”2. This essay will focus on illustrating bioconservatives' belief in the harmful nature of human enhancement in relation to two hypothetical but still highly controversial forms of it: the expansion of human cognitive capabilities using nanotechnology and... middle of paper... . ...performance... and perfecting our nature”53 in what could become a “triumph of obstinacy over talent”54.
