The book provides an in-depth discussion on the human nature concept from different perspectives and from different disciplines, analyzing its use in the doping debate and researching its normative overtones. The relation between natural talent and enhanced abilities is scrutinized within a proper conceptual and theoretical framework: is doping to be seen as a factor of the athlete's dehumanization or is it a tool to fulfill his/her aspirations to go faster, higher and stronger? Which characteristics make sports such a peculiar subject of ethical discussion and what are the, both intrinsic and extrinsic, moral dangers and opportunities involved in athletic enhancement? This volume combines fundamental philosophical anthropological reflection with applied ethics and socio-cultural and empirical approaches. Furthermore guidelines will be presented to decision- and policy-makers on local, national and international levels. Zooming in on the intrinsic issue of what is valuable about our homo sapiens biological condition, this volume devotes only scant attention to the specific issue of natural talent and why such talent is appreciated so differently than biotechnological origins of ability. In addition, specific aspects of sports such as its competitive nature and its direct display of bodily prowess provide good reason to single out the issue of natural athletic talent for sustained ethical scrutiny.​
