Abstract
The therapy/enhancement distinction is a controversial one in the philosophy of medicine, yet the idea of enhancement is rarely if ever questioned as a proper goal of sports medicine. This opens up latitude to those who may seek to use elite sport as a vehicle of legitimation for their nature-transcending ideology. Given recent claims by transhumanists to develop our human nature and powers with the aid of biotechnology, I sketch out two interpretations of the myth of Prometheus, in Hesiod and Aeschylus, which can help frame the moral limits of sports medicine. By way of conclusion I assemble some banal reminders: We are mortal beings; our vulnerability to disease, injury and the waning of our powers, far from something we can overcome or eliminate, represent natural limits both for morality and medicine generally and sports medicine in particular
