Abstract
The purpose of this article is to present the critical approaches made by Alasdair MacIntyre and Charles Taylor to the priority of the right over the good on Habermas’ dicourse ethics, criticisms that depart from the consideration that the moral agent, historical and socially conditioned, acts for reasons other than (only) the impartial consideration of all individuals. Claiming that the priority of the right over the good would disconnect individuals of their motivations, abstracting them from their cultural background and contingencies often determinants of their ethical life, the objections also claim that the choice of a particular set of conditions to be fulfilled for the validity of moral norms bind discourse ethics to a particular ethos, permeated of values shaped historically by a kind of society whose practices are not universals
