What counts as a good moral argument, or a valid moral assertion or claim? What does ¡®validity¡¯ mean in the moral realm? Lots of ink has been spilled on these and related questions in the past few decades, but not much has been settled. In what follows I will spill a little more, this time with the hope that bringing epistemic concerns directly to bear on them might shed some light. A particular focus will be J¨¹rgen Habermas¡¯ discourse ethics and its conceptions of communicative rationality and ideal discourse. I will try to show that Habermas and some of his defenders in the philosophy of education literature fail to get the epistemology right and, as a result, both their defenses of Habermasian communicative rationality and critiques of non-Habermasian alternatives fail as well. I will also argue that these epistemic failures do not threaten their Habermas-based educational recommendations, which can be justified on other, more straightforwardly moral, grounds %K Dialogicality %K discourse ethics %K educational justice %K epistemic criteria %K Habermas %K justification %K moral epistemology %K virtue %U https://journals.sagepub.com/doi/full/10.1177/1477878518801753
