The Ethics of Human Enhancement and the Boundaries of Therapy
Quick fact
The U.S. Food and Drug Administration partly justifies approval of eugenol and other drugs used 'off-label' for enhancement based on a distinction that many bioethicists argue is conceptually unstable.
Why this is interesting
Vaccines are celebrated, but would you give your child a pill that makes them – and their descendants – permanently taller or smarter?

Understanding The Ethics of Human Enhancement and the Boundaries of Therapy
Imagine a doctor who restores a patient's lost vision. That's therapy. Now imagine that same doctor can give sight to someone with perfect vision, granting them night vision like a cat. That's enhancement. The line seems simple, but it blurs quickly. Consider a drug that improves memory in Alzheimer's patients – therapy. That same drug could boost memory in healthy students – enhancement. The ethical issue is that therapy is almost universally accepted, but enhancement raises questions about fairness, coercion, and the meaning of being human. This distinction is central to debates about genetic modification, cognitive enhancers, and even cosmetic surgery.
A deeper explanation
The therapy-enhancement distinction is not just descriptive; it carries moral weight. Critics argue that there is no irrefutable line between restoring and improving. For example, vaccinations enhance the immune system, yet we consider them therapeutic. Whole-genome sequencing could identify disease risks and also non-medical traits. The debate splits into two main camps: bioconservatives, who warn that enhancement undermines human dignity and authenticity, and transhumanists, who see it as a moral duty to improve ourselves. Key philosophical questions include: is there a fixed human nature? Does enhancement threaten personal identity? How should we ensure fair access? These questions challenge us to define the purpose of medicine and the limits of scientific progress.
