ABSTRACT It is argued that sport, like science or medicine, is a valued human practice and is characterised as much by the moral manner in which its participants conduct themselves as by the pursuit of its own skills, standards and excellences. Virtues, such as justice, honesty and courage, are not only necessary to pursue its goals but to protect it from being corrupted by external interests. After explicating the practice view of sport in contrast to the sociological view, the nature (...) of competition in sport is discussed before examining two related issues: winning at all costs and the taking of performance-enhancing drugs. The importance of practices to education and the good life is also outlined. (shrink)
