In this article, I revise the normative account of sport that I proposed in ‘William J. Morgan’s “conventionalist internalism” approach. Furthering internalism? A critical hermeneutical response.’ I first present Habermas’ discursive ethics, placing emphasis on his interpretation of the relationship between moral (Kantian) and ethical (Hegelian/hermeneutical) principles. Then, I provide a reformulation of my account by both drawing on Habermas and going beyond him—as I go beyond Habermas, I will refer to the account as ‘discourse-ethics based.’ To further explore the (...) normative potential of the account, I connect its main tenets to the three main normative theories of sport (formalism, broad internalism, and deep conventionalism) and illustrate it with examples from anti-doping governance.
