In this article I examine whether Moral Foundations Theory can fulfil the promises that Haidt claims for the theory: that it will help in developing new approaches to moral education and to the moral conflicts that divide our diverse society. I argue that, first, the model that Haidt suggests for understanding the plurality of moralities--a shared foundation underlying diverse moralities--does not help to overcome conflicts. A better understanding of the nature and background of moral conflicts can lead to a more respectful attitude towards people with conflicting views, but need not contribute to ending conflicts. Second, I show that pervasive moral conflicts should be dealt with on the level of politics. They require a morality of compromising. Third, I examine why this approach does not seem to work in the USA.
