The late Zhou of China and the Classical age of Greece both saw great impetus in intellectual thought and were marked by intense warfare. Being closely linked to warfare in antiquity, sports was a vital, commonplace activity whose jargon and practices naturally informed philosophical discourses. One can thus observe convergences between athletics and ethics in texts which took shape in these times and places, a phenomenon which I shall refer to as “athl-ethics.” In this paper, I separately examine and then compare athl-ethic phenomenon in Mencius and in the Nicomachean Ethics. Both texts are rife with sports metaphors. I regard the use of sports-derived imagery as a thin form of athl-ethicism. Sports, however, did more than inspire useful analogies. Physical training and competition were considered occasions for nourishing and practicing virtue. This generated thicker forms of athl-ethicism.
