Abstract: Advances in cognitive neuroscience make cosmetic neurology in some form inevitable and will give rise to extremely difficult ethical issues.
Comment: This short paper introduces the ethical challenges related to cognitive enhancement. It lists some existing enhancing drugs, discusses the differences between developing drugs which treat diseases and those developed to enhance healthy individuals. The ethical challenges it considers include: safety and possible harmfulness of enhancing drugs; whether suffering and hardships are integral parts of human development and thus removing them might be problematic; whether the possibility of enhancement won't result in explicit and implicit coercive pressure to enhance, at the cost of human happiness. Chatterjee's text will serve well as an introduction to human enhancement in medical and applied ethics classes. In higher level classes it will be useful to supplement it with other, more in-depth papers engaging with specific problems.
