This essay aims to philosophically understand flow in popular scientific. For this I use the terminology of Jean-Luc Nancy in Corpus. Nancys critic of the discussion on the body, and his critic against a wide spread phrase in western European culture, hoc est enim corpus meum: this is my body, give him the purpose to re-conceptualize the body. Nancys terminology show us the way to account the body as its own subject, with its own expressions. From that I try to show that flow is an example of a bodily expression that comes out of itself. My declaration supports with an article by Jennifer Hardes and Bryan Hogeveen, both prevailing in sociology and sport science. They use Nancys terminology and Heidegger’s three fundamental notions of Being in human existence, to rephrase flow in popular scientific. Their goal is to provide and to make flow visible in a new meaning, with the use of Nancy and Heidegger, so to understand the body as relational to other bodies and its environment. It signifies a meaning of flow as a bodily expression that is unique for every individual. Finally, this new meaning of flow visualize an ethical implication of including athletes in sport, which alludes to all who practise sport, even those who doesn’t reach for the stars at the elite level.
