Within the philosophy of sport considerable attention has been given to the practices employed by elite athletes to improve performance. For example, Schneider and Butcher (66) and Tamburrini (71), along with many others, have tackled the issue of the use of performance-enhancing drugs in sport 1 ; Munthe (51; 52), Tamburrini (72), and Miah (43;44;45) have considered the potential role of genetic modification in performance enhancement; and Loland (38; 39) has addressed the logic of progress that underlies both elite sport and the performanceenhancement practices that it generates.Although each of these deals with a specific issue, Hoberman (29; 30) provided an early, and largely successful, attempt to produce an overview of what we might refer to as "the technological attitude to the elite sporting body." 2 Hoberman is critical of the practices of sport science (particularly sport psychology) and sports medicine. He regards the performance principle in elite sport as motivating a technological attitude to the sporting body that treats the body as a machine (the notion of "mortal engines"). This attitude manifests itself in practices such as the use of performance-enhancing drugs, genetic modification, 3 and extreme training. This results in an alienation of the athlete from his or her body. Hoberman's analysis does, however, tend toward an ideological account and in doing so neglects to consider any possible self-deception on the part of athletes that might accompany the adoption of the role of an elite competitor. This article will focus on that selfdeception, treating it as a motivated project by considering the Sartrean notion of "bad faith" (mauvaise foi) (61: pp. 47-70).The central thesis here is that there are elements of the structure and practice of "record sports" and "quasi-record sports" (39: p. 128) that facilitate or promote self-deception to a greater degree than most other social practices. 4 This article is concerned with self-deception on the part of athletes. It is possible that sport facilitates self-deception among spectators, but that is beyond the scope of this discussion. I begin by considering Hoberman's account of the technologizing of the elite sporting body as a means of both contextualizing and clarifying the problem of self-deception in relation to the performance-enhancement practices in much elite competitive sport. Having identified a concern, I then consider Sartre's approach to bad faith before addressing the possibility of avoiding bad faith in elite sport and the possible implications of such avoidance. I then locate bad faith within elite Downloaded by [University of Western Ontario] at 23:55 17 November 2014 CULBERTSON 66 sport. Finally, I argue that record sports and quasirecord sports are especially fertile grounds for self-deception.In all the work cited in the first paragraph, a central concern is the ethical issues raised by performance-enhancement practices in elite sport. This article does not attempt to explicitly deal with questions of ethics. This is not to den...
