The struggle for the future, and perhaps the soul, of sport is an ongoing conflict. The arguments pressed by the opponents of doping control have not changed much at all in the quarter-century since Thomas H. Murray, PhD, of the Hastings Center began his research into the ethics of performance enhancement in sport. Five arguments come up repeatedly in one variation or another. Each of them seems plausible at first, but each one has serious flaws.
