Political philosophers often grapple with the issue of the legitimacy of state coercion. Aristotle, a perfectionist, opines that all men hold an objective account of the good life. As regards legitimacy, he entails that state policies are justified only when all its members comprehend the value that has been identified in accordance with the true notion of good. Aristotle argues that the state should facilitate the encouragement of objectively valuable notions of the good. Ronald Dworkin, a neutralist, proposes a specific (...) model of the good life so that one can live well. He holds that certain elements of the ethical conception lead to various notions of the good and, in matters of legitimacy, the state should be neutral towards the notion of good. This is so because A cannot make B’s life better by way of the coercive means of the state. This paper throws light on Aristotle’s and Dworkin’s dialogues on the moral foundations of legitimacy (conceived during their notion of the good life). Therefore, I argue that, in contrast to perfectionism, Dworkin justifies his liberal principle of legitimacy through the idea of state neutrality. But, eventually, Dworkin’s arguments overlook his ethical foundation or admissible towards perfectionism, which is emaciated enough to offer any justification for the principle of legitimacy. (shrink)
