The aim of this paper is to defend the position that aesthetics and ethics in sport are not two separate domains or aspects. In sport, the aesthetic and the ethical both arise from sport’s attractiveness or from the pleasure sport offers to its activists and consumers. To think about sport philosophically, we should find a link and a principle beyond this division as a source of both the aesthetic and the ethical in sport. The philosophy and philosophical sociology of Jean-Marie (...) Guyau is presented as a response to this problem. Two points of fundamental importance are considered critically here: his criticism of any reductionism, and life or the idea of life as key principle of a philosophical system which puts ethics and aesthetics together.
