The aim of this article is twofold. Against the traditional interpretation of ‘the conscience of Huckleberry Finn’ (for which Jonathan Bennett’s article with this title is the locus classicus) as a conflict between conscience and sympathy, I propose a new interpretation of Huck’s inner conflict, in terms of Huck’s mastery of (the) moral language and its integration with his moral feelings. The second aim is to show how this interpretation can provide insight into a particular aspect of moral education: learning a moral language. A moral education that has a proper regard for the flexibility of moral language and the importance of the integration of moral language and (pre-)moral feelings should prevent such conflicts as Huck experienced from arising.
