The use of certain performance-enhancing drugs (PED) is banned in sport. I discuss critically standard justifications of the ban based on arguments from two widely used criteria: fairness and harms to health. I argue that these arguments on their own are inadequate, and only make sense within a normative understanding of athletic performance and the value of sport. In the discourse over PED, the distinction between “natural” and “artificial” performance has exerted significant impact. I examine whether the distinction makes sense (...) from a moral point of view. I propose an understanding of “natural” athletic performance by combining biological knowledge of training with an interpretation of the normative structure of sport. I conclude that this understanding can serve as moral justification of the PED ban and enable critical and analytically based line drawing between acceptable and nonacceptable performance-enhancing means in sport.

Understanding the ethics of enhancement begins with getting clear about the concept, as well as the factors likely to move people to pursue biomedical enhancement. This article first considers the usefulness of the distinction between therapy and enhancement for understanding the ethics of enhancement. Once the conceptual underbrush has been cleared away, we can move on to ethics. The next section examines critically a number of arguments that have been offered to defend biomedical enhancement, or, at least, to claim that (...) efforts to deter it are either ethically or practically mistaken. Finally, the article considers a set of arguments that take the ethics of enhancement to be a serious matter and that gives reasons to question whether some biomedical enhancements, for some purposes, may be ethically suspect.
