Sport, Rules and Values presents a philosophical perspective on some issues concerning the character of sport. Central questions for the text are motivated from 'real life' sporting examples as described in newspaper reports. For instance, the (supposed) subjectivity of umpiring decisions is explored via an examination of the judging of ice-skating at the Salt Lake City Olympic Games of 2002. Throughout, the presentation is rich in concrete cases from sporting situations, including cricket, baseball, American football, and soccer. While granting the constitutive nature of the rules of sport, discussion focuses on three broad uses commonly urged for rules: in defining sport; in judging or assessing sport (as deployed by judges or umpires); and in characterising the value of sport - especially if that value is regarded as moral value. In general, Sport, Rules and Values rejects a conception of the determinacy of rules as possible within sport. Overall, this work exemplifies the dependence of philosophical considerations of sport on ideas from philosophy more generally. The book's argumentative structures originate in the writings of Ludwig Wittgenstein without explicitly being an exposition of those ideas. It views philosophy as addressing the specific issues of particular persons, rather than approaching perennial problems. The result is a distinctive and appealing conception both of sport and of its philosophical investigation.
